Abstract

The invention discloses self-oil-seepingsilicone rubberand a preparation method thereof. The self-oil-seeping silicone rubber is formed by mixing raw materials such as raw rubber with the vinylmole content of 0.12%, raw rubber with the vinylmole content of 8.0%, fumed silica, phenyl silicone oil, hydroxyl silicone oil, stearic acid and the like by a kneading machine. The self-oil-seepingsilicone rubber is good in self-oil-seeping lubricating effect, better in mechanical performance and machinability and wider in application range.

Description

technical field [0001] The invention relates to the manufacture of silicone rubber materials, in particular to a self-separating oil silicone rubber and a preparation method thereof, belonging to the field of rubber material manufacture. Background technique [0002] Silicone rubber has many excellent properties such as good high and low temperature resistance, ozone resistance, weather resistance, insulation and production inertia, and is widely used in various fields of the national economy. However, the friction coefficient of silicone rubber is relatively high, and its self-lubricating effect is not good, so it is not suitable for application in fields that require lubrication. Therefore, the study of self-analyzing oil silicone rubber has very positive significance. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, and provide a self-analyzing oil silicone rubber and a preparation method thereof. The ...
