Embodiment 1

[0024] S1 Put the raw materials of each component into the kneader in proportion and mix them evenly;

[0025] S2 Add the mixture obtained in S1 into a twin-screw extruder, control the temperature of the extruder and die at 180°C, and cool the extrudate to ambient temperature;

[0026] S3 sends the cooled extrudate to the granulator to obtain the finished thermoplastic flame-retardant plastic granules.

Embodiment 2

[0028] The difference from Example 1 is that the temperature in step S2 is 220°C.

Embodiment 3

[0030] The difference from Example 1 is that the temperature in step S2 is 200°C.

Abstract

The invention provides a thermoplastic fire retardant plastic. The plastic is made from the following raw materials by weight: 80-100 parts of polypropylene, 40-60 parts of polyethylene, 60-100 parts of terpene resin, 20-40 parts of polystyrene, 20-30 parts of nitrile rubber, 10-20 parts of dibutyl sebacate, 10-20 parts of polyimide, 12-24 parts of melamine, 10-30 parts of liquid paraffin, 8-20 parts of antimonous trioxide, 40-80 parts of magnesium hydroxide, 10-30 parts of nanometre titanium oxide, 10-22 parts of zinc stearate, 5-20 parts of 2,6-tertiary butyl-4-methylphenol, 20-40 parts of fire retardant, 20-50 parts of filler, 4-10 parts of silicone and 5-20 parts of organosilane. The thermoplastic fire retardant plastic provided by the invention has a good fire retardant property.

Description

technical field [0001] The invention provides a thermoplastic, which has good flame retardancy and belongs to the technical field of polymer materials. Background technique [0002] Plastic is a polymer material with special properties. It has the characteristics of light weight, good chemical stability, corrosion resistance, good insulation, convenient molding, and low cost. It is widely used in electronics industry, automobile manufacturing, aerospace, industry and other fields. . [0003] However, plastics are flammable and burn quickly, producing a large amount of toxic gases. According to statistics, casualties caused by suffocation and smoke poisoning in fires account for 50-80% of the total number of casualties in fires. In recent years, the rapid development of electronics, construction, aviation and automobile industries has put forward higher requirements on the performance of plastics. Among them, flame-retardant plastics are not easy to burn, have low flame pr...
