Vloga razreda ZnOrubber v zmesi gume:

1. ZnO razred gume acts as an activator or accelerator in the formulation,

2. ZnO razred gume can be used as an acid absorbent. When the rubber is vulcanized, it can absorb certain natural substances produced by the vulcanization reaction, such as HCl and so on.

3. ZnO razred gume can improve the thermal performance of the rubber compound.

4. ZnO razred gume can activate the entire vulcanization system,Zinc oxide and stearic acid together form zinc soap, improve the solubility of zinc oxide in the rubber compound, and form a complex with the accelerator, which is particularly active , It reacts with sulfur to form a strong vulcanizing agent.

5. ZnO razred gume can increase the crosslink density. Zinc oxide reacts with stearic acid to form Zn2++ salt, which chelates with the pendant group of the sulfur-containing rubber accelerator to stabilize the weak bond and change the cleavage position of the sulfur bond. Vulcanize rubber to generate shorter cross-links, increase new cross-links, and increase cross-link density.

6. ZnO razred gume can improve the aging resistance of the vulcanized rubber. During vulcanization and use, the polysulfide bond breaks, and the generated H2S will accelerate the cracking of the rubber. Zinc oxide will react with it to form new cross-linked bonds, stabilize the vulcanized network, and improve the resistance Aging performance.
