Zinc oxide and stearic acid together form zinc soap, improve the solubility of zinc oxide in the compound, and with the accelerator to form a complex, this complex is particularly lively, it reacts with sulfur to produce a very strong vulcanizing agent.
Zinc oxide and stearic acid to form Zn2 + + salt, which is chelated with the sulfur-containing rubber accelerator side-chaining group, so that the weak bond in a stable state, change the cracking position of sulfur bonds, so that rubber vulcanization to produce shorter cross-linking , Add new cross-linking keys to increase the cross-linking density.
In the process of vulcanization and use, the polysulfide bond breaks, the resulting H2S will accelerate the rubber cracking, zinc oxide reacts with it to form new crosslinking bonds, stabilize the vulcanization network, and improve the aging resistance. Rubber technology consulting network for the majority of rubber industry friends to provide rubber technology, natural rubber, rubber price information, rubber training and learning, rubber materials exchange learning exchange platform. We strive to build a rubber company's favorite rubber technology information exchange platform.
In short, the main role of zinc oxide, 1) in the formula from the role of activator or accelerator, 2) as a sour agent, in the rubber vulcanization is to absorb some of the vulcanization of the production of acidic substances, such as HCl and so on. 3) can improve the thermal properties of the compound.

Soluble in aromatics, ethanol, acetone, and halo-hydrocarbon, TAIC is in-soluble in water. It is a triazine ring multi-functional olefin monomer, which may be subjected to aco-polymerization or be homogenously polymerized or crosslinked with various olefins, during which various characteristic reactions for aliphatic olefins may take place. Under normal temperature, it has stable properties and can be for extended periods.
Under normal temperature, TAC is a lightly yellow to colorless liquid or crystalline, and has a melting point of 25-27ºC, density of 1.1133g/mL(30ºC), a viscosity of 1.26×10-2 Pa·s (30ºC) and refractivity of 1.5049 (25ºC). It is insoluble in water, while remaining soluble in ethanol, acetone & heptane, petroleum ether, solvent oil, soybean extracted oil, and halo-hydrocarbon. Under normal temperature, it has stable properties and can be stored for extended periods.
