High-sealing silicone rubber material

Abstract

The invention provides a high-sealing silicone rubber material which comprises nano kaolin, a water blocking agent, a damping agent, low phenyl silicone rubber, nano ceramic powder, high-temperature-resistant resin, a fire retardant, zinc oxide, a heat stabilizer, a nano anti-wear agent, fluorinated silicone rubber and a cross-linking agent. Concretely, the silicone rubber is prepared from the following components in parts by weight: 3 to 5 parts of nano kaolin, 1 to 2 parts of water blocking agent, 1 to 2 parts of damping agent, 60 to 75 parts of low phenyl silicone rubber, 5 to 7 parts of nano ceramic powder, 10 to 15 parts of high-temperature-resistant resin, 2 to 3 parts of fire retardant, 1 to 2 parts of zinc oxide, 1.3 to 1.7 parts of heat stabilizer, 2 to 3 parts of nano anti-wear agent, 20 to 30 parts of fluorinated silicone rubber and 2 to 4 parts of cross-linking agent. The high-sealing silicone rubber material has the advantages of favorable sealing property, excellent aging resistance, long service life, favorable oil resistance, favorable solvent resistance and favorable high-temperature aging resistance. In addition, the material also has the advantages of high elasticity, low compression set rate, high temperature resistance, high mechanical properties and the like.

Description

technical field [0001] The invention relates to the technical field of high-temperature-resistant and high-sealing materials, in particular to a high-sealing silicone rubber material. Background technique [0002] Rubber is the latex taken from plants such as rubber trees and rubber grasses. After processing, it is a material with elasticity, insulation, and impermeability to water and air. High elastic polymer compound. 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 have unique properties, so rubber is a good raw material for making sealing rings. Rubber seals are a general basic component in sealing devices. Rubber seals are a type of rubber products widely used in sealing technology. They are widely used due to their small elastic modulus, high elongation, and air permeability...

Problems solved by technology

In the working environment, the lubrication system of mechanical equipment contains acid and alkali components, which can easily penetrate into the seals, causing the seals to expand and affect the service life of the seals. Moreover, long-term harsh working environments, such as high temperature and high pressure, will accelerate The damage rate of the seals is reduced, and the replacement cycle of the seals is short, which brings troubles to the continuous production of the enterprise
