Embodiment Construction

[0027] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0028] A flame-retardant injection molding material, wherein the flame-retardant injection molding material comprises:

[0029] Polycarbonate 15-18%;

[0030] Polyethyl ether 8-12%;

[0031] Wood pellet material 21%~29%;

[0032] Active hydrogen calcium 10% to 16%;

[0033] Stearic acid 16%~18%;

[0034] Compound foaming agent 2% to 3%;

[0035] Nanoscale graphite powder 5-9%;

[0036] Industrial paraffin 11% to 13%;

[0037] Impact modifier 6% to 9%;

[0038] Flame retardant 6% to 8%.

[0039] Among them, the flame retardant is selected from one of nitrogen-based flame retardants, phosphorus-based flame retardants and nitrogen-phosphorus-based flame retardants. The compound blowing agent is selected from one of alkanes and fluorocarbons. The impact modifier includes: 35-45% styrene-butadiene copolymer; 55-65% ...

Abstract

The invention discloses a flame retardant injection molding material. The flame retardant injection molding material comprises the following components by mass percent: 15-18% of polycarbonate, 8-12% of polyethylether, 21-29% of wood granular materials, 10-16% of activated hydrogen carbon, 16-18% of stearic acid, 2-3% of compound foaming agent, 5-9% of nano graphite powder, 11-13% of industrial paraffin, 6-9% of impact modifier and 6-8% of flame retardant. The parts manufactured by using the injection molding material not only have good heat dissipation functions but also can be effectively prevented from spontaneous combustion when the working environment temperatures are too high and the heat dissipation effects are not good.

Description

technical field [0001] The invention relates to an injection molding material, in particular to an injection molding material with flame retardancy. Background technique [0002] With the development of technology and the change of people's ideas, many non-metallic parts appear in parts such as computer components, electrical appliances and electronic equipment. Among them, the dominant material of non-metal parts is plastic parts, which are easy to process, easy to install and light to use, so they are more and more favored by the electronic equipment industry. The use of plastic parts is an inevitable requirement for the future development of automobiles. [0003] The so-called injection molding (injection molding) refers to the method of injecting the heated and melted material into the mold, cooling and solidifying to obtain the molded product. The specific process is that the granular or powdery plastic is fed from the hopper of the injection molding machine into the h...
