Problems solved by technology

[0002] High-performance engineering plastics are basically monopolized by the United States and Japan, especially most of the domestic high-performance engineering plastics are imported from Japan, and the price is relatively expensive
At present, the products of domestic counterparts are mainly concentrated in general-purpose products with low requirements. Almost no one is involved in the field of high-performance engineering plastics. It is related to the inability of my country's fine chemical industry to produce high-performance additives

Abstract

The invention discloses a polyethylene terephthalate fiber-adding inflaming retarding material. The polyethylene terephthalate fiber-adding inflaming retarding material is prepared from the following raw materials in parts by weight: 35-60 parts of polyethylene terephthalate, 5-20 parts of flexibilizer, 5-15 parts of fire retardant, 15-30 parts of glass fiber, 2 parts of montmorillonoid and 0.8 part of polyethylene glycol diglycidyl ether. The special PET (polyethylene terephthalate) fiber-adding inflaming retarding material has the characteristics of low price, low mould processing temperature, rapid crystallization rate, low warping, good flowability, good weather resistance and ultraviolet ray resistance, high thermal deformation temperature (195 DEG C), high surface finish, good fire resistance (UL-V0), rapid formation period, low formation shrinkage (0.2%), high notch impact strength (IDZO11-17KJ / m<2>) and the like, and is the preferred product for computer accessories, automobile accessories, electric connectors, switches, mechanical shell accessories and the like.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a polyethylene terephthalate fiber-added flame-retardant material and a preparation method thereof. Background technique [0002] High-performance engineering plastics are basically monopolized by the United States and Japan, especially most of the domestic high-performance engineering plastics are imported from Japan, and the price is relatively expensive. At present, the products of domestic counterparts are mainly concentrated in general-purpose products with low requirements. Almost no one is involved in the field of high-performance engineering plastics. It is related to the inability of my country's fine chemical industry to produce high-performance additives. With the rapid development of my country's economy, in terms of adjusting the structure and transforming the new growth model, metal substitutes for parts near the vehicle engine and electronic products ar...
