Abstract

The invention discloses a sealing material for high-pressure medium delivery valves, and relates to the technical field of sealing materials. The sealing material comprises, by weight, 60-70 parts of butyl rubber, 15-20 parts of stearic acid, 12-17 parts of phenolic resin, 10-15 parts of attapulgite, 10-15 parts of ceramic powder, 8-12 parts of asbestos powder, 8-12 parts of hydrogenated castor oil, 6-10 parts of alkylphenol ethoxylates, 5-8 parts of adhesive assistants, 5-8 parts of epoxidized soybean oil, 3-6 parts of nanometer titanium dioxide, 2-4 parts of polyoxyethylene polyoxy-propanol amidogen ether, 2-4 parts of barium stearate and 1-2 parts of alumina powder. The sealing material has the advantages that the sealing material is excellent in high-pressure resistance, impact resistance, corrosion resistance and high-temperature and low-temperature resistance; good sealing effects can be realized, high-pressure media can be effectively prevented from leaking, and accordingly safety accidents can be prevented; the adhesion performance of raw materials further can be improved by the aid of the adhesive assistants, and rubber mixing and vulcanizing can be facilitated.

Description

Technical field: [0001] The invention relates to the technical field of sealing materials, in particular to a sealing material for high-pressure medium delivery valves. Background technique: [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. For high-pressure media, the delivery valve system used needs to have excellent high-pressure resistance, impact resistance and sealing performance, and the sealing performance is higher. The quality of the sealing material directly affects the sealing effect and reduces the delivery pressure. And if the service life of the sealing material is short, the number of replacements will be increased, thereby affecting the conveying efficiency. Invention content: [0003] The technical problem to be solved by the present invention is to provide a sealing material ...
