Abstract

Wear-resistant silicone rubber is composed of a component A serving as a base material and a component B serving as a cross-linking agent, the component A is composed of, by mass, 100 parts of siloxane, 5-20 parts of a reinforcing agent, 3-8 parts of a vulcanizing agent and 10-30 parts of wear-resistant filler, the component B is composed of, by mass, 2-5 parts of a catalyst, 1-3 parts of an anti-aging agent and 0.5-3 part of cross-linking agent, and the mass ratio of the component A to component B is 100: 0.5-5. The wear-resistant filler in the component A is prepared from the following components in parts by mass: 5-10 parts of silicon dioxide, 5-10 parts of zirconium dioxide, 5-10 parts of aluminum oxide, 1-5 parts of calcium carbonate, 1-5 parts of magnesium sulfate, 1-3 parts of calcium sulfate, 0.01-0.1 part of diamond particles, 0.1-0.5 part of wear-resistant carbon black, 0.1-0.5 part of graphene and 0.01-0.5 part of chromium powder. The invention also discloses a preparation method of the wear-resistant silicone rubber and an application of the wear-resistant silicone rubber in a mold.

Description

technical field [0001] The invention belongs to the field of silicone rubber, and in particular relates to a wear-resistant silicone rubber and its preparation method and application. Background technique [0002] Silicone rubber is a kind of rubber whose main chain is composed of silicon and oxygen atoms alternately, and there are usually two organic groups attached to the silicon atoms. Silicone rubber was first synthesized by the United States using ferric chloride as a catalyst. In 1945, silicone rubber products came out. After decades of vigorous development, the silicone rubber industry has made remarkable achievements. With the rapid growth of consumption, the silicone rubber industry has begun to transform from high-performance special rubber to popular synthetic rubber, becoming one of the most widely used rubber varieties. The development of the silicone rubber industry is not only a single development of a single industry, but involves the common development of...
