Abstract

The invention provides a silicone rubber composite material used for seal rings. The composite material is prepared from the following components in parts by weight: 100 parts of silicone rubber, 0.5-1.5 parts of peroxidation vulcanizing agent, 10-15 parts of fluoroether rubber, 20-30 parts of plaster fibers, 25-35 parts of fillers, 1-3 parts of coupling agent, 0.5-1 part of release agent, 2-3 parts of anti-aging agent, 12-15 parts of plasticizer and 1.5-2 parts of softening agent. The invention also provides a preparation method of the composite material. With good tensile strength and oil resistance, the silicone rubber composite material used for seal rings, which is provided by the invention, can be used on various occasions.

Description

Technical field: [0001] The invention relates to a composite material, in particular to a silicone rubber composite material used for a sealing ring and a preparation method thereof. Background technique: [0002] Silicone rubber refers to the rubber whose main chain is composed of silicon and oxygen atoms alternately, and there are usually two organic groups attached to the silicon atoms. Ordinary silicone rubber is mainly composed of silicone chains containing methyl groups and a small amount of vinyl groups. The introduction of phenyl can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano can improve the temperature and oil resistance of silicone rubber. Silicone rubber has good low temperature resistance, and generally can still work at -55°C. After the introduction of phenyl groups, it can reach -73°C. The heat resistance of silicone rubber is also outstanding. It can work for a long time at 180 °C, an...
