Abstract

The invention relates to a formulation of a haloflex hose. The components and the weight fraction are 100 parts of aloflex, 20-30 parts of fast extrusion carbon soot, 50-70 parts of pot clay, 25-35 parts of trioctyl trimellitate, 10-15 parts of magnesium oxide, 2-4 parts of fatty acid amide, 2-4 parts of dimercapto thiazole, and 1-3 parts of zinc fatty acid ester. Compared with the traditional products, the formulation has obviously effect of the maximum elongation of vulcanized rubber 450%; tearing strength 55KN / m, and 100 modulus 4.5Mpa. The formulation using thiadiazole vulcanizing system and high efficiency flow promotor is used for procuding the haloflex hose, has high maximum elongation and tearing strength, can solve the problem of difficult die-removing of the product; the product percent of pass is more than 95%.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to the formulation of chlorinated polyethylene rubber injection hoses with thiadiazole vulcanization system. Background technique [0002] Chlorinated polyethylene (referred to as CM) rubber hose refers to a kind of air intake pipe used in automobiles. Its structure is full of rubber with corrugations in the middle, and it can only be produced by glue injection. Chlorinated polyethylene is a chlorine-containing polymer without double bonds in the main chain. It has good weather resistance, ozone resistance, impact resistance, chemical resistance and oil resistance. It is more and more widely used in the manufacture of wires and cables, hoses and auto parts. There are three commonly used vulcanization systems for formulas with CM as the main material: 1. Peroxide vulcanization system 2. Thiourea vulcanization system 3. Thiadiazole vulcanization system. The vulcanization techno...
