With rapid economic development, zinc oxide has been widely used in various aspects of life, especially in rubber. Why can zinc oxide be used in rubber? Zinc oxide What is the role of zinc oxide in rubber?
    Zinc oxide It is an indispensable additive in rubber production. Zinc oxide can be called an activator of natural latex. Zinc oxide and stearic acid are important reactants in rubber vulcanization and are also one of the important raw materials for rubber production. The hardness of rubber depends on the mixture of zinc oxide and stearic acid.
I. The role of zinc oxide in black and dark rubber tires and radial tires: improving the thermal conductivity, wear resistance, tear resistance, tensile strength, etc. of the products, and saving zinc oxide consumption by about 30%.
II. The role of zinc oxide in rubber products
① When active zinc oxide is mainly used as a rubber enhancer, it can improve the corrosion resistance, tear resistance, elasticity and elongation of rubber.
② Rubber vulcanization accelerator, as a multifunctional rubber composite, is mainly used as a vulcanization activator and reinforcing agent for natural rubber, synthetic rubber and latex.
③ Zinc oxide When used as a vulcanization activator, it is evenly distributed in the rubber material, with a large contact area with hydrogen sulfide, and a large chance of interfacial reaction.
④ When zinc oxide is used as a curing oxidizing agent, it plays a significant role in improving the activity of the accelerator, reducing the amount of accelerator, and shortening the curing cycle.
⑤ Zinc oxide can accelerate the vulcanization speed, improve the thermal conductivity of the vulcanized rubber, and make the vulcanization reaction more thorough.
