Problems solved by technology

[0002] Compositions based on polyvinyl chloride resin are often used as covered wires in automotive wiring harnesses. Although they have good flame retardancy and wear resistance, polyvinyl chloride resins tend to burn to produce a large amount of halogen gas due to incineration or vehicle accident fires Hazardous substances such as
[0003] And, owing to adding a large amount of low-molecular substances such as plasticizer, stabilizer and lubricant in the composition of existing polyvinyl chloride resin, for example, the residual low-molecular straight chain of conventional plasticizer because of esterification Alcohol and by-product gaseous volatiles such as isomerized aldehydes and alcohols; and the linear alcohols and by-generated gaseous volatiles such as isomerized aldehydes and alcohols are difficult to completely remove from plasticizers by means of industrial distillation, so that The processed automotive wiring harness has an unpleasant and harmful smell

Abstract

The invention relates to an odorless flame-retardant vehicle wire harness cable material composition, which comprises the following components in parts by weight: 50-60 parts of a polyolefin resin, 10-20 parts of an alcohol-free plasticizer, 3-10 parts of nano silicon dioxide, 2-5 parts of a calcium-zinc composite stabilizer, 15-20 parts of a low-density polyethylene resin, 2-8 parts of an inorganic flame retardant and 0.2-0.4 part of an antioxidant. The vehicle wire harness prepared from the odorless flame-retardant vehicle wire harness cable material composition has the characteristics of odorlessness, good flame-retardant effect and the like, does not contain halogen elements, and is environment-friendly.

Description

Technical field [0001] The invention relates to an odorless flame-retardant cable material composition for automobile wire harnesses, belonging to the field of wire and cable materials. Background technique [0002] The composition based on polyvinyl chloride resin is usually used as the covered wire in automobile wiring harness. Although it has good flame-retardant and abrasion resistance, polyvinyl chloride resin is often burnt due to incineration or vehicle accidents and fires to produce a large amount of halogen gas Hazardous substances, which cause environmental problems. [0003] Moreover, since a large amount of low-molecular substances such as plasticizers, stabilizers, and lubricants are added to the existing polyvinyl chloride resin composition, for example, the low-molecular-weight linear residues of conventional plasticizers due to the esterification reaction Alcohols and by-produced isomeric aldehydes, alcohols and other gaseous volatiles; and the linear alcohols and ...
