Abstract

The invention provides a preparation method for modified mica powder used for rubber product filler, and belongs to the field of preparation for mica powder. In order to overcome the technical problem that the mica powder has high surface energy in the prior art, thus agglomeration is quite easy to generate when fill with the rubber raw material, and reinforcement effect is difficult to perform, the invention provides the preparation method for modified mica powder. The preparation method comprises implementing surface modification processing for the mica powder by using titanate, and controlling the modified time and temperature. The prepared modified mica powder can be used as semi-reinforcing filler and bulking filler to increase the volume and mass of the rubber, and reduce the production cost. Moreover, the hardness of the rubber is raised, and the oil resistant performance and technological performance are improved. The modified mica powder can be used for rubber product filler widely.

Description

technical field [0001] The invention belongs to the field of mica powder preparation, and in particular relates to a preparation method of modified mica powder used as filler for rubber products. Background technique [0002] Rubber products mainly refer to products produced and processed using natural and synthetic rubber as the main raw materials, including [0003] Including rubber products remanufactured from waste rubber. Because the types of rubber products are more complicated. making it difficult to carry out detailed [0004] categorized. Under normal circumstances, rubber products can be roughly divided into two categories: natural rubber products and synthetic rubber products. [0005] Natural rubber products. The main raw material used in this type of rubber products is natural rubber, which is mainly produced in clover rubber. After the rubber tree skin is cut, milky white liquid will flow out, which is usually called latex. After latex is processed, natu...
