[0003] The document with the notification number CN 104371207 B discloses a flame retardant material and its preparation method. The flame retardant material is composed of the following components: 65wt% to 75wt% of high impact polystyrene, 10wt% to 30wt% Polyphenylene ether and 6wt% to 15wt% hypophosphite, although the material has simple components, low price, and high-efficiency flame retardancy, it is suitable for micro and thin-walled electronic and electrical equipment, compared with existing flame-retardant materials of the same type , the content of polyphenylene ether and phosphate flame retardant in the flame retardant material is greatly reduced, while reducing the cost, the heat distortion temperature of the flame retardant material can be greatly increased, but the preparation method of the material needs to go through many steps, which is difficult to control accomplish
[0004] The document whose notification number is CN 104278362 B discloses a preparation method of a flame-retardant fiber material. The steps of the preparation method of the flame-retardant fiber material are as follows: (1) take 15-28 parts of polyurethane, Chitin is 15-22 parts, after heating polyurethane and chitin, melt blending in a high-speed mixer; (2) adding 6-12 parts of chlorinated polyethylene to the melt blended material, The polyarylether resin is 8-14 parts, keep the temperature constant, and then carry out melt blending; (3) heat the melted blended material to become a spinning solution, degas the spinning solution, and melt it after degassing Spinning, cooling, heat stretching and heat setting to prepare flame-retardant fiber materials, but the cost of raw materials for this preparation method is relatively high

Abstract

The invention belongs to the technical field of material preparation, and discloses a preparation method of an electric power flame retardant material. The method comprises the following steps of step1, taking 70 to 120 parts of polypropylene and 60 to 100 parts of acrylonitrile-butadiene-styrene copolymers; performing uniform stirring and heating to 80 to 95 DEG C in a funnel of an extrusion machine; performing melting blending; step 2, adding 2 to 5 parts of anti-static agents, 1 to 5 parts of fire retardants, 2 to 6 parts of chlorinated paraffins and 3 to 7 parts of flame retardant synergists into the molten blending material; maintaining the temperature unchanged; performing melting extrusion; finally performing molding to obtain an anti-static flame retardant material. The preparation method solves the technical problems of flame retardant performance and anti-static performance of an electric power plastic product.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a method for preparing an electric flame-retardant material. Background technique [0002] There are many plastic products in traditional power materials, such as plastic power boxes and plastic warning tapes. At present, these plastic products are mostly made of polypropylene (PP), polyethylene (PE), acrylonitrile-butadiene-styrene The materials of copolymer (ABS) plastic products, the static electricity collection and flammability of these materials bring great harm to people, how to modify these materials and solve the flame retardant and antistatic properties of plastic resins is an urgent technology to be solved question. [0003] The document with the notification number CN 104371207 B discloses a flame retardant material and its preparation method. The flame retardant material is composed of the following components: 65wt% to 75wt% of high impact polystyrene,...
