Abstract
The invention discloses a high-sealing synthetic rubber material. The high-sealing synthetic rubber material is prepared from the following raw materials, by weight, 8.6-9.8 parts of dibutyl phthalate, 7.6-10 parts of chloroprene rubber, 6.1-7.5 parts of conductive graphite, 3.4-4.5 parts of modified epoxy phenolic resin, 4.6-6.7 parts of lithium catalyst polyisoprene rubber, 2.3-4.7 parts of methacrylic acid, 1.5-2.6 parts of trithiocyanuric acid and 0.8-1.3 parts of aluminium oxide. The compression permanent deformation of the rubber material is 68%, the compression permanent deformation is reduced greatly, therefore during the medium conveying process, the compression permanent deformation is good, and rubber tube oil leakage is prevented effectively. The defects are overcome that orange peel phenomena of traditional rubbers are easy to generate during the production vulcanizing process and therefore product performances are affected. The orange peel phenomena are improved through change of the formula and technology conditions, therefore no orange peel phenomena are generated during the vulcanizing process, the prepared rubber has good performances, and there is no oil leakage during the medium conveying process.
