Environmentally friendly black cat carbon black

Environmentally friendly black cat carbon black is one of the rubber reinforcing agents, which can increase the wear resistance of rubber (such as rubber for tires).

Reinforcement of rubber means that the tensile strength, tear strength and wear resistance of rubber can be significantly improved. For non-self-reinforcing synthetic rubber, if no reinforcing agent is added, it has no use value. Adding carbon black and other reinforcing agents can increase the strength of these rubbers by several times to ten times. It is difficult to achieve rubber products by using pure rubber to make rubber products. After extensive experimentation, it has been found that adding carbon black to rubber can significantly improve rubber. Performance. If the proper amount of carbon black is added to the tire formula to improve its wear resistance and improve the service life, adding a certain amount of carbon black to the hose formula can increase its strength. Therefore, the purpose of adding carbon black to the rubber is mainly Reinforce.

It is difficult to achieve the expectations of rubber products made of pure rubber. After extensive experiments, it has been found that the addition of carbon black to rubber can significantly improve the performance of rubber. For example, adding a proper amount of carbon black to the tire formulation can improve its wear resistance and increase the service life, and adding a certain amount of carbon black to the hose formula can increase its strength. Therefore, the purpose of adding carbon black to rubber is mainly to reinforce.

Carbon black manufacturers talk about rubber vulcanization system

The vulcanization of rubber is to convert the substantially plastic raw rubber into an elastic and dimensionally stable product by chemical cross-linking between rubber molecules. The vulcanized rubber has stable physical properties and an extended temperature range. The term "Curing" is commonly used throughout the rubber industry and plays an important role in rubber chemistry. The ability of the vulcanization (crosslinking) reaction between rubber molecular chains depends on its structure. Unsaturated diene rubbers (such as natural rubber, styrene butadiene rubber and nitrile rubber) contain unsaturated double bonds in the molecular chain, which can form molecules with substitution or addition reaction with sulfur, phenolic resin and organic peroxide. Cross-linking. Saturated rubber is generally crosslinked by a radical having a certain energy (such as an organic peroxide) and high-energy radiation. A rubber containing a special functional group (such as chlorosulfonated polyethylene) is crosslinked by a specific reaction of various functional groups with a predetermined substance, for example, a sulfinamide group in a rubber is reacted by reacting with a metal oxide or an amine.
