Abstract

The invention relates to a polyamide 66 composite material used for extruding thin-wall shaping articles, which is made from raw materials of the following percentage by weight: 70 percent to 94.8 percent of nylon 66, 0.1 percent to 24 percent of tackifier, 5 percent to 20 percent of compatilizer and 0.1 percent to 1 percent of antioxidant. The invention has the advantages that: the method of making is simple and the impact toughness of the made material is substantially improved while maintaining original excellent properties of nylon 66; the strength of fused mass is high, thereby the fused mass can be extruded or made into various thin-wall shaping articles through blow molding; particularly, due to possessing ideal compliance, high tenacity, low friction coefficient, the material can be used in high performance polymer pipe for surgery.

Description

technical field [0001] The invention relates to a polyamide 66 composite material for extruding thin-walled profiles, which can be used for extruding or blow molding into various thin-walled profiles, especially due to the material's good flexibility, high toughness, and low coefficient of friction, The utility model relates to a high-performance polymer pipe used in medical operations, and belongs to the technical field of engineering plastics. Background technique [0002] Nylon 66 has good physical and mechanical properties, such as high tensile strength, excellent wear resistance, good impact resistance, and outstanding chemical and oil resistance. It is the most widely used variety among the five major engineering plastics and is widely used in various Electrical and electronic equipment and home appliances. The number average molecular weight of commonly used nylon 66 is very low (<30000), such a low molecular weight makes the melt strength and viscosity too low to...
