Abstract

Belonging to the technical field of high polymer materials, the invention relates to a flame retardant electroconductive nylon composite material. It is composed of the following raw materials by weight: 200-230 parts of nylon 66 resin; 60-90 parts of nylon 12 resin; 3-5 parts of a coupling agent; 60-100 parts of a filling material; 50-90 parts of a flame retardant; 1.0-2.0 parts of an antioxidant; 30-45 parts of an electroconductive agent; 90-120 parts of reinforced fibers; and 1.1-2.3 parts of a surface modifier. The flame retardant electroconductive nylon composite material of the invention has tensile strength of more than 170MPa, bending strength of more than 240MPa, izod notched impact strength of more than 23kj / m<2>, a melt index of over 27g / 10min, and a flame retardant grade up to V-0 (UL-94-1.6mm).And due to the adding of the electroconductive agent, static electricity can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant conductive nylon composite material. Background technique [0002] Due to the lack of flame retardancy and poor antistatic properties of nylon materials, it is limited to occasions with strict fire protection requirements, thus restricting the expansion of its application fields. In view of this, it is of positive significance to develop conductive nylon composite materials with excellent flame retardant and antistatic effects. The technical solutions to be introduced below are based on this premise. Contents of the invention [0003] The task of the present invention is to provide a flame-retardant conductive nylon composite material that helps to ensure excellent strength and is conducive to embodying excellent flame retardancy and antistatic properties. [0004] Task of the present invention is accomplished like this, a kind of flame-...
