Problems solved by technology

The barrier layer is powdery, discontinuous, and low in strength. It is difficult for this barrier layer alone to play the role of heat insulation and fire resistance.
[0004] Existing peroxide vulcanized hose assemblies generally use silicone rubber as the rubber material, which has poor oil resistance and fire resistance, which greatly limits its application occasions

Abstract

The invention relates to an oil-resistant fireproof rubber material for a peroxide vulcanized hose assembly and a preparation method. The oil-resistant fireproof rubber material comprises the following components in parts by weight: 80-100 parts of rubber, 45-60 parts of a flame-retardant filler, 10-30 parts of a fluxing agent, 1.0-2.0 parts of a chloroplatinic acid solution, 0.8-1.5 parts of a peroxide vulcanizing agent and 0.5-2.0 parts of a coupling agent. The preparation method comprises the following steps: premixing silicone rubber, fluorinated silicone rubber and phenyl silicone rubber on a rubber mixing machine to prepare premixed rubber; and gradually adding the flame-retardant filler and the fluxing agent into the premixed rubber, dropwise adding the chloroplatinic acid solution and the coupling agent, finally adding the peroxide vulcanizing agent, uniformly mixing to obtain a rubber compound, and vulcanizing and molding the rubber compound to obtain the oil-resistant and fire-resistant rubber product. Compared with the prior art, the material has the advantages of certain mechanical properties, oil resistance, flame combustion resistance and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an oil-resistant fire-resistant rubber compound for a peroxide-vulcanized hose assembly and a preparation method. Background technique [0002] Silicone materials have excellent high and low temperature resistance, ozone resistance, weather resistance, excellent electrical insulation and chemical stability. At the same time, they have less smoke and no toxicity when burning, low calorific value, and slow flame propagation. Therefore, they are widely used in aerospace, electronics and electrical appliances. , power transmission and other fields have been widely used. [0003] The main chain of silicone rubber contains Si-O bonds, and the cleavage of the main chain and the oxidation of side groups are the main reactions of silicone rubber in a high-temperature aerobic atmosphere, in which the cleavage of the main chain generates cyclic siloxane, which softens the silicone rubber; ...
