Formula of ozone-resistant rubber part

Abstract

The invention relates to a formula of an ozone-resistant rubber part. The formula of the ozone-resistant rubber part is characterized by comprising the following components in parts by weight: 75 parts of chloroprene rubber, 25 parts of butadiene-styrene rubber, 100 parts of ethylene propylene rubber, 3 parts of a plasticizer, 1 part of white carbon black, 1 part of zinc oxide, 2 parts of an antiager, 3 parts of polypropylene cellulose, 12 parts of an antioxidant, 2 parts of fibers, 3 parts of modified coal ash, 10 parts of epichlorohydrin rubber, 12 parts of polyamide wax micropowder, 5 parts of polycaprolactone, 3 parts of dibenzothiazyl disulfide and 5 parts of paraffin. According to the formula of the ozone-resistant rubber part provided by the invention, a rubber main material which is good in ozone resistance is selected and meanwhile, the antiager and paraffin which are good in ozone resistance are further used in the formula, so that the ozone resistance of the ozone-resistant rubber part for a transformer is improved. The ozone-resistant rubber part provided by the invention is simple in processing process, the raw materials are easily available and the cost is low; therefore, the ozone-resistant rubber part has potential economic benefit and social meaning.

Description

technical field [0001] The invention relates to a chemical product, especially a formula for ozone-resistant rubber parts. Background technique [0002] Rubber-plastic alloy is a kind of material that takes nitrile rubber as the main base material and adds part of polyvinyl chloride for effective modification. From the perspective of polymer material research, through polyvinyl chloride macromolecules The closure of the double bond endows the rubber-plastic alloy with a series of superior properties. There will be ozone in the working environment of many rubber parts. Ozone has a relatively large impact on compression deformation and resilience, so the material properties of rubber materials are high, and most rubbers have poor ozone resistance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a formula for ozone-resistant rubber parts. [0004] In order to solve the above-mentioned technical problems, the formu...
