According to relevant statistics, half of the zinc oxide used in the industrial field is in the rubber field. Zinc oxide and stearic acid are important reactants for rubber vulcanization and are one of the raw materials for rubber manufacturing.
The role in rubber products
①Active zinc oxide is mainly used as a reinforcing agent for rubber, so that the rubber has good corrosion resistance, tear resistance, elasticity and elongation.
② Accelerator used in rubber vulcanization process is a multifunctional rubber compounding agent, mainly used as vulcanization active agent and reinforcing agent for natural rubber, synthetic rubber and latex.
③When used as a vulcanization activator, it is evenly distributed in the rubber compound, has a large contact area with hydrogen sulfide, and has a greater opportunity for interface reaction. In addition, the active zinc oxide product has the catalytic effect of active substances, so that zinc oxide can be converted into The conversion rate of zinc sulfide is high.
④ As a vulcanization oxidant, its function is to increase the activity of the accelerator, reduce the amount of the accelerator, and shorten the vulcanization cycle.
⑤ It can speed up the vulcanization speed, improve the thermal conductivity of the vulcanized rubber, and make the vulcanization more thorough.
⑥In the rubber industry, especially in the production of transparent rubber products, activated zinc oxide is an excellent vulcanization activator.
Zinc oxide is also an important additive for tires.
(1) Highly dispersed active zinc oxide has higher dispersibility, fluidity and compatibility, which can improve the physical and mechanical properties of polymer products such as rubber and plastics, and can improve processing performance and vulcanization speed.
(2) Compared with conventional zinc oxide, highly dispersed active zinc oxide requires less amount to achieve the same application effect.
(3) Without changing the original operating conditions and operating habits of the manufacturer, highly dispersed active zinc oxide has obvious advantages in price.
