Abstract

The invention relates to a rubber sealing element raw material applied to an electrical appliance in a high temperature, high pressure or high humidity environment. The raw material is obtained by mixing a main body system material, a reinforcing system material, a softening system material, an auxiliary system material, a protective system material and a vulcanization system material. The raw material is prepared by the following steps of: mixing the main body system material, the reinforcing system material and the softening system material, discharging and standing; mixing the auxiliary system material with the protective system material, discharging and standing; and adding all raw materials into a mixing roll for mixing, discharging and standing. The sealing material prepared by the method has high temperature resistance, low temperature resistance and ageing resistance, and can be taken as a raw material of an electrical appliance sealing element.

Description

technical field [0001] The invention relates to the field of rubber material production, in particular to a raw material for rubber seals used in electrical appliances under high-temperature, high-pressure or high-humidity environments and a preparation method thereof. Background technique [0002] Rubber is divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. Rubber seals are a common basic component in sealing devices, and play a very important role in the contradiction between leakage and sealing. Solve leakage and sealing problems in the process of man's conquest of nature. It has been an important way to promote technological progress, prevent and reduce environmental pollution. Rubber seals are a type of rubber products widely ...
