Effect of zinc stearate in rubber compound
Release time：
2021-11-12
It is well known that zinc stearate has many functions, such as softening and plasticizing. As an external lubricant, it is conducive to the full diffusion of carbon black, white carbon black and zinc oxide, and the reaction of zinc oxide or alkaline accelerator can promote its activity, or the main vulcanization accelerator can play the role of a second accelerator, which can accelerate the hardening. What is the effect of zinc stearate on glue? The following Hongyuan Chemical Industry will explain to you.

What is the effect of zinc stearate on glue? The following Hongyuan Chemical Industry will explain to you.
1. Zinc stearate has a great influence on rubber materials, and its main effect is carbon black
2. Zinc stearate significantly reduces the viscosity of the adhesive, improves the technical performance, and significantly improves the plasticity of the adhesive
3. The length of fatty acid carbon chain has no effect on its efficacy, for example, the softening effect of lauric acid and oleic acid is also good;
4. However, too high unsaturation of oleic acid will interfere with rubber processing, and oleic acid will also increase rubber aging;
5. The acid value of lauric acid is very high, which will greatly delay the vulcanization of rubber. The factory needs to change the formula and adjust the process parameters. Due to the restriction of formula and consideration of some parameters, all enterprises basically only use stearic acid.
