GRANULAR BUTYL RUBBER COMPOSITION HAVING ANTI-STICKING EFFECT, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

摘要

The present invention relates to the field of rubber preparation, and in particular, to a granular butyl rubber composition having an anti-sticking effect, and a preparation method therefor and an application thereof. The composition is formed by uniformly mixing granular butyl rubber and a small amount of a solid additive; the solid additive is one or a mixture of two or more of talcum powder, calcium stearate, magnesium stearate, calcium carbonate, carbon black, and argil; moreover, a) the specific surface area BET (m2/g) of each component of the solid additive satisfies 0.1
