Abstract

The invention discloses a preparation method of modified mica powder for rubber product packing, and belongs to the field of mica powder preparation. The preparation method aims at solving the technical problems that in the prior art, due to the fact that the surface energy of the mica powder is high, an agglomeration phenomenon is extremely prone to occurring if the mica powder is directly filled in rubber raw materials, and the reinforcing effect of the mica powder is difficult to achieve. According to the preparation method of the modified mica powder for the rubber product packing, surface modification processing is performed on the mica powder with a silane coupling agent, and the modification time and temperature are controlled, so that the mica powder can be effectively dispersed into organic polymers, the compatibility of the mica powder and the organic matter is improved, and the reinforcing effect is fully achieved.

Description

Technical field [0001] The present invention belongs to the field of preparation of Yunmu Fan, which involves a method of modified Yunmu powder for the filler of rubber products. Background technique [0002] Rubber products mainly refer to products produced by natural and synthetic rubber as the main raw materials, which also include rubber products produced by waste rubber.Rubber products are widely used in various industries. [0003] Carbon black is the main enhancement filler of rubber. The composition of 90%to 99%is element carbon, and the rest are a small amount of volatile scores and moisture.During the production of carbon black, its surface adsorption or combination of a small amount of carboxyl, cymbal, phenol, and laidone groups and other chemical groups.In the past, the reinforcement performance of charcoal black only depends on its particle size (ratio of surface area) and structural, and has nothing to do with its surface chemical properties.In recent years, a larg...
