Non-halogen fire-retardant Nylon 6 and Nylon 66 alloy

Abstract

A non-halogen fire-retardant nylon6 and nylon66 alloy consists of nylon6 30-65wt%, nylon66 30-65wt%, fire retardantA0.1-15wt%, fire retardantB0.1-15wt%, carbon-forming agent 0.1-2wt%, antioxidant 0.1-1wt% and anti-ultraviolet agent 0.1-1wt%. It has no environmental pollution, has efficient fire-retardant performance, better rigid, heat-resisting performances and stable size. It can be used for various household electrical appliances.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant nylon 6 and nylon 66 alloy, in particular to a halogen-free flame-retardant that can be used for injection molding various electronic and electrical equipment and household appliances that have environmental protection and flame-retardant requirements and are for export. Nylon 6 and Nylon 66 alloys. technical background [0002] Nylon 6 has good physical and mechanical properties, such as high tensile strength, excellent wear resistance, good impact resistance, and outstanding chemical and oil resistance. Nylon 66 is a homogeneous thermoplastic polymer with six symmetrical methylene groups in its molecular structure. It has the advantages of high strength, wear resistance, solvent resistance, good self-lubrication and wide temperature range. It is the most widely used One of engineering plastics, widely used in various electronic and electrical equipment and home appliances. Since nearly 80% of ...

Problems solved by technology

However, in recent years, brominated flame retardants have been troubled by the problem of dioxins. At the same time, the flame-retardant polymer materials using it (bromine-antimony system) will generate a large amount of smoke and corrosive gases during thermal cracking and combustion. At present, the EU and Japan has successively issued laws and regulations prohibiting the use of such flame retardants
