Problems solved by technology

The antimony trioxide used in the bromine-antimony system contains lead oxide. Although antimony-containing flame retardant materials can meet EU standards under normal circumstances, some internationally renowned large companies have formulated stricter standards than ROHS. Germany BOSH The company stipulates that the lead content must be less than 2ppm, which is difficult for material manufacturers to achieve

Abstract

The invention discloses a low-lead flame-retardant material for corrugated pipes for vehicles. The low-lead flame-retardant material is prepared from the following raw materials in parts by weight: 70-100 parts of polypropylene, 30-50 parts of talcum powder, 2-5 parts of black master batch, 1-2 parts of coupling agent, 5-8 parts of compatilizer, 15-30 parts of flame retardant, 3-5 parts of impact modifier, 3-5 parts of organic clay nano reinforced elastomer composite material, 1-3 parts of lubricant and 1-3 parts of antioxidant. The invention also discloses a preparation method of the low-lead flame-retardant material for corrugated pipes for vehicles. The low-lead flame-retardant material has the advantages of excellent flame retardancy, excellent mechanical properties and very low lead content.

Description

technical field [0001] The invention belongs to the technical field of corrugated pipes for vehicles, and in particular relates to a low-lead flame-retardant material used for corrugated pipes for vehicles, its preparation method and application. Background technique [0002] Polypropylene is widely used in automotive bellows due to its excellent processability, chemical resistance and mechanical strength. However, polypropylene itself is extremely flammable. At present, some automobile wiring harnesses protect the bellows, and the vehicle will generate a lot of heat during driving. In order to prevent the vehicle from burning due to the heat of the bellows or traffic accidents during operation, it will emit lead substances that are not conducive to health and affect the human body. Health, it is necessary to develop an environmentally friendly low-lead flame-retardant bellows material. [0003] In consideration of cost and performance, the flame retardants used by factori...
