Problems solved by technology

PP and PE have excellent resistance to weak acid and weak alkali, but they are not resistant to high temperature, and after adding flame retardants, they lose a lot of performance, so it is difficult to meet the requirements of wire harness tubes at the same time; in addition, PP has poor impact resistance at -40°C low temperature; Although PA is resistant to high temperature, its resistance to weak acid and weak alkali is not good. Therefore, the development of a material that is economical and can meet the requirements of corrugated wire harness tubes will have a good market prospect.

Abstract

The invention discloses a material for an automobile wire harness pipe. The material comprises, by weight, 20-30 parts of phenolic aldehyde epoxy resin, 50-80 parts of polymethyl methacrylate, 2-8 parts of nano-titanium dioxide, 5-8 parts of diethylaminopropylamine, 34-42 parts of polyketone resin, 7-11 parts of flame retardants, 5-8 parts of zinc stearate, 3-6 parts of antioxidants and 6-9 partsof lubricating agents. A produced halogen-free flame retardant polyketone material has excellent low-temperature performance, flame resistance and acid and alkali resistance. The produced wire harnesspipe material can meet market requirements of high-temperature resistance, low-temperature resistance, low smoke and flame resistance and has excellent market prospect, an organic silicon material possibly improves toughness and heat resistance of the wire harness pipe material, and the material has the advantages of simple design, low cost and high productivity.

Description

technical field [0001] The invention relates to the technical field of wire harnesses, in particular to a material used for automobile wire harness tubes and a preparation method thereof. Background technique [0002] The small-diameter wire harness tube (with an inner diameter of 5-130mm) mainly protects the wire harness from damage, thereby protecting the safety of the energized circuit, so it needs good insulation performance, so most of them are currently using PP, PE and PA materials. . Because of the need for safety, this type of wire harness tube needs to be flame retardant, and in some cases, it needs to be resistant to low temperature impact at -40°C, high temperature resistance above 100°C, weak acid resistance, weak alkali resistance and chemical resistance, and needs to be generated when burning. Very little smoke. PP and PE have excellent resistance to weak acid and weak alkali, but they are not resistant to high temperature, and after adding flame retardants,...
