Rubber protective wax can extend the service life of rubber products and is widely used in tire companies. It is a physical antioxidant for the production of radial tires, bias tires, engineering tires and other rubber products. It forms a stable film on the surface of the rubber that does not react with ozone, isolating the ozone from the rubber and playing a protective role.
The properties of rubber protective wax are affected by many factors, among which the carbon number distribution of rubber protective wax, the content of isomeric paraffin, the use temperature and rubber additives. The distribution of carbon number and the content of isomeric paraffin are the key factors, which have a decisive influence on the protective properties of rubber protective wax. Mainly used for biasing tires, transport belts and industrial rubber products, profiles, sponge rubber, cable sheaths and other rubber physical aging. All steel radial tires, half steel radial tires, heavy engineering tires, bias tires and other rubber physical aging. Physical aging of rubber for high-grade car tires and special purpose tires.
The formulation and optimization of rubber protective wax are realized by adding appropriate additives to paraffin wax and microcrystalline wax as raw materials. The specific optimization work mainly focuses on the distribution of carbon number and the composition of iso-alkanes. The formula optimization of Richon rubber protective wax is mainly based on the application environment of rubber tires and other products, reasonable adjustment of raw material proportion, accurate control of the content of isomeric paraffin between the specified carbon number to meet the application requirements of the product. At present, the carbon distribution test method has been improved for high melting point petroleum wax, especially for rubber protection wax.

At present, the Chinese SBS market is still in a stalemate and consolidation stage, with a long-short game of cost, supply and demand. May is about to end, and there is still no clear news guidance for SBS.
In the short term:
First, the butadiene market fluctuates violently, and the guidance is unclear: the spot butadiene market fell rapidly in mid-to-early May, reaching a relative low in the middle of the month, a 5%-6% drop from the beginning of the month. Then, under the influence of some foreign news, the butadiene market began to rebound violently. As of May 22, rebounding by about 5%. The price of butadiene fluctuated violently, and the future trend needs to be continuously monitored. At present, the cost is still high.
Second, the supply continues to be low: In mid-May, the Dushanzi unit was fully shut down for maintenance, and Huizhou Li Changrong is expected to shut down in the short term in the near future. Most other private and joint venture companies are still in a state of suspension, and the SBS operating load is still less than 40%. The market spot continues to be consumed, and imports have also decreased. The supply side continues to support.
Third, the demand is released slowly: the road reform start-up in May is still in a slow increase stage, TPR shoe material orders are gradually reduced, and the start-up has declined. At present, most terminals maintain rigid demand purchases, and the demand side is difficult to have a significant support effect.
Therefore, before the end of May, under the influence of cost and supply, SBS prices will remain strong. Different brands in the market have different sources of supply. With the differentiation of terminal purchasing volumes, the price gap between brands will gradually widen, and the market will be mainly in a wide range of fluctuations. In terms of exports, as SBS production in May is still at a low level, it is expected that the export volume in May may decrease compared with April, but it may still be higher than the same period last year. Increasing export volume is an effective way to ease competitive pressure.

Carbon black is a commonly used filler material and reinforcing agent, widely used in rubber, plastic, paint, printing ink and other fields. The dispersion of carbon black is one of the important factors affecting its performance, poor dispersion will lead to the deterioration of the strength, hardness, wear resistance and other properties of the material. Therefore, how to improve the dispersion of carbon black is an important problem.
ⅠInfluencing factors of carbon black dispersion
1．Carbon black particle size: carbon black with small particle size is easy to disperse, and the larger the particle size, the more difficult to disperse.
2．Surface properties of carbon black: the chemical properties and hydrophilicity of carbon black surface will affect its dispersion, and carbon black with good surface hydrophilicity is easy to disperse.
3．Selection of dispersants: different dispersants have different dispersion effects on carbon black, and the choice of suitable dispersants can improve the dispersion of carbon black.
4．Shear force in the dispersion process: the greater the shear force, the higher the dispersion of carbon black.
5．The choice of solvent: different solvents also have an impact on the dispersion effect of carbon black, and the choice of suitable solvents can improve the dispersion of carbon black.
ⅡMethods to improve the dispersion of carbon black
1．Choose the right dispersant: Choosing the right dispersant is the key to improving the dispersion of carbon black. Commonly used dispersants are surfactants, polymers, colloids and ion exchange resins. Different dispersants have different dispersion effects on carbon black, and the appropriate dispersant should be selected according to the specific situation.
2．Increase the shear force: the greater the shear force, the higher the dispersion of carbon black. The dispersion of carbon black can be improved by using high speed agitator, high shear mixer and other equipment to increase shear force.
3．Choose the right solvent: different solvents also affect the dispersion effect of carbon black, and choose the right solvent to improve the dispersion of carbon black. In general, carbon black has poor hydrophilicity, and solvents with good surface hydrophilicity should be selected for dispersion.

Rubber yellowing is a manifestation of rubber aging, mainly caused by the following reasons:
- Aging reaction: During the use or storage of rubber, it is affected by the action of heat energy, light energy, radiation energy, as well as oxygen, ozone, water and variable metal, which leads to the breakage and cross-linking reaction of rubber molecular chains, and then causes aging, manifested as yellowing, hardening, brittleness and so on.
- Ultraviolet radiation: ultraviolet light can cause the cracking of carbon-carbon bonds or carbon-hydrogen bonds in the rubber molecular chain, resulting in a concentration of activity, leading to degradation of the molecular chain, resulting in yellowing.
- The role of heat and oxygen: over time, rubber materials will undergo oxidation reactions, and heat will accelerate this process, resulting in material discoloration.
- Rubber structure: There is a bond energy between polymer macromolecular chain bonds, and when the energy provided by the outside world is greater than the bond energy, the molecular chain is prone to activity concentration, leading to degradation and yellowing.
- Impurities and metal ions: If there are trace metals and impurities such as NO-3 in silicone rubber, it may cause yellowing after secondary vulcanization.
- Vulcanization process: silicone rubber in the vulcanization process, if the vulcanization temperature is too high or the time is too long, it will lead to the oxidation of the vinyl in the rubber compound, forming conjugated diolefin compounds, so that the silicone rubber turns yellow.
- Reaction container impurities: In the process of rubber reaction, the reaction container may introduce trace metal impurities, such as iron, chromium, etc., which may also lead to yellow silicone rubber.
- Rubber spray frosting: Compounding agents in rubber products, such as sulfur, accelerators, antioxidants, etc., if the amount exceeds the solubility in the rubber, it will migrate from the inside of the rubber to the surface and precipitate, resulting in frosting phenomenon, which may also cause yellowing.
- Rubber formulations: Certain additives used in rubber formulations, such as antioxidants, plasticizers, etc., may produce color changes during the aging process.
In order to prevent rubber from turning yellow, the following measures can be taken:
Optimize rubber formulation and use additives with better aging resistance.
Control vulcanization temperature and time to avoid excessive vulcanization.
Use anti-UV agents and antioxidants to reduce the effects of light and oxygen.
Keep rubber products stored in a suitable environment to avoid high temperature and direct sunlight.
The use of appropriate packaging and storage conditions to reduce the impact of external factors on rubber.
Through these methods, the process of rubber aging and yellowing can be delayed and the service life of rubber products can be extended.

Application of Paraffin Wax
Because rubber aging is an inevitable change, rubber antioxidants are used in the production of rubber products to inhibit the aging of products and extend the service life of products. Rubber antioxidants are divided into physical and chemical antioxidants, and paraffin wax is commonly used as physical antioxidants. This passage mainly introduces how paraffin wax plays an anti-aging effect in rubber products and matters that should be paid attention to.
Paraffin is a white, odorless waxy solid, alkane structure, and it is a mixture of straight chain paraffin, branched paraffin and ring hydrocarbons. The commonly used paraffin wax in rubber is ordinary paraffin wax, microcrystalline wax, rubber protective wax. Paraffin wax in rubber is a physical protective agent or softener, which can improve the anti-aging property of rubber and increase the flexibility of rubber. It does not participate in the reaction during vulcanization and is only dissolved in the rubber. When the vulcanization is cooled, it is in a supersaturated state and slowly migrates to the surface of the vulcanized rubber, forming a protective film that insulates against the erosion of oxygen and ozone in the air, thus playing a role in preventing aging.
Paraffin supplied by Richon has the following advantages: the protective film of paraffin is compact and uniform, and there is a certain thickness, which plays a good protective role; The protective film has strong adhesion to rubber; The protective film has a certain stiffness, that is, ductility; The protective film has the corresponding ability to resist high and low temperatures.
The migration rate of common paraffin in rubber is faster, and the protective film can be formed quickly. The migration rate of microcrystalline wax in rubber is relatively slow, and the time of forming protective film is slightly longer, and the protective effect is longer. The migration rate of rubber protective wax in rubber is between the two. The solubility of different varieties of paraffin wax in rubber is different, ordinary paraffin wax > rubber protective wax > microcrystalline wax. When the amount of paraffin exceeds its solubility, it will migrate to the rubber surface, but the amount is too much, the protective film is too thick, and it is easy to crack and fall off, but it affects the protective effect.
