Abstract

The invention discloses an alkali-resistant rubber hose and belongs to the technical field of manufacture of rubber components. The alkali-resistant rubber hose is prepared from raw materials in parts by weight as follows: 100 parts of chlorinated butyl rubber, 6-10 parts of rosin, 6-10 parts of petroleum resin, 6-10 parts of ferric oxide, 0.1-0.2 parts of nanoscale perlite powder, 20-30 parts of dilauryl thiodipropionate, 15-20 parts of zinc stearate, 0.1-0.2 parts of sulphur, 1-3 parts of isopropyl alcohol, 15-20 parts of paraffin and 1-5 parts of thiourea dioxide. According to the alkali-resistant rubber hose, the rosin, the petroleum resin, ferric oxide, the nanoscale perlite powder, isopropyl alcohol and thiourea dioxide in a special ratio are added to rubber for modification, so that the alkali resistance of the rubber hose is improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing rubber fittings, and in particular relates to an alkali-resistant rubber hose. Background technique [0002] At present, there are rubber hoses with various special properties on the market, and alkali-resistant rubber hose is one of them.
