Abstract

The invention is concerned with alloy with fibre made of poly(hexamethylene adipamide) and phthalamide phthalic diamide. It relates to 36.15 to 46.15 percent of poly (hexamethylene adipamide), 20 to 30 percent of phthalamide phthalic diamide (PPA), 30 to 33 percent of long fiberglas, 0.1 to 0.2 percent of lubricant and 0.1 to 0.3 percent of antioxidant in weight proportion. This also shows the preparation method of the said alloy. This product and method can improve the surface quality and control the cost of material and product, and it is fit for the high demand of heat resisting, such as engine accessory, dynamoelectric tool shell, inside and outside parts of electrical apparatus with and details of cars.

Description

technical field [0001] The invention relates to a polyhexamethylene adipate and polyphthalamide fiber-added alloy, in particular to a polyhexamethylene adipate which improves the surface quality of products and effectively controls the processing cost of materials and product production. Amine and polyphthalamide-added fiber alloy and its preparation method, the material of the invention is mainly used for mechanical parts with high heat resistance requirements, electric tool shells, internal and external parts of electrical appliances, auto parts and the like. Background technique [0002] At present, the domestically produced polyhexamethylene adipate (PA66) plus glass fiber modified materials are made of pure PA66 plus glass fiber or PA66 and polycaprolactam (PA6) blended with glass fiber. The advantages of this type of material Some materials have good flow properties and are easy to process and shape, but some high-end heat-resistant materials cannot meet the product re...
