Problems solved by technology

While gaining its performance requirements, it also loses the aesthetic value of its appearance
[0003] Moreover, because ABS material is a poor conductor of electricity, it is easy to accumulate static charge during processing and use. When the static charge accumulates to a certain extent, static electricity will cause the material to absorb dust and cause material damage, and may also generate static spark discharge, causing The chemical product warehouse exploded and caught fire, causing major personal accidents

preparation example Construction

[0053] The preparation method of described transparent flame-retardant antistatic ABS material comprises the steps:

[0054] (1) Add MABS, phosphorus-nitrogen flame retardant and zinc borate into a high-temperature mixer, pre-mix, granulate and cool to obtain a flame-retardant masterbatch;

[0055](2) Fully mix MABS, antistatic agent, flame retardant masterbatch and toughening agent in a high-speed mixer for 10-60 minutes to obtain a premix;

[0056] (3) The premixed material is conveyed to the twin-screw extruder through a precisely metered feeding device. Under the shearing, mixing and conveying of the screw, the material can be fully melted and compounded, and then extruded, granulated and dried to obtain Transparent flame retardant antistatic ABS material.

[0057] The processing conditions of the melt extrusion of the twin-screw extruder are as follows: the temperature of the first zone is 180°C, the temperature of the second zone is 190°C, the temperature of the third z...

[0065]

[0066] As can be seen from the examples and comparative examples in Table 2, compared with brominated flame retardants, the present invention selects phosphorus-nitrogen flame retardants and zinc borate flame retardant masterbatches with MABS resin as the carrier as flame retardants , the mechanical properties are relatively excellent, and the flow properties are better than the traditional flame-retardant ABS. More importantly, its light transmittan...

Abstract

The invention provides a transparent flame-retardant antistatic ABS material and a preparation method thereof. The transparent flame-retardant antistatic ABS material is prepared from, by weight, 60-85 parts of resin A, 10-15 parts of an antistatic agent, 10-20 parts of flame retardation master batches and 5-25 parts of a flexibilizer. The flame retardation master batches are prepared from, by weight, 60-90 parts of resin B, 10-30 parts of a phosphor and nitrogen flame retardant, and 5-20 parts of zinc borate; and the resin A is same to the resin B in specifications. Addition of the antistatic agent in the invention reduces the surface resistivity of the above composite material to 10<8>omega from 10<16>omega, and makes the composite material have a good antistatic effect.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a transparent flame-retardant and antistatic ABS material and a preparation method thereof. Background technique [0002] ABS resin is a terpolymer composed of styrene, butadiene and acrylonitrile. It combines the high fluidity of styrene, the rubber toughness of butadiene and the chemical resistance of acrylonitrile. It has excellent processing performance, Low temperature resistance, electrical insulation, chemical corrosion resistance, high gloss and excellent electroplating performance, as well as good creep resistance, high dimensional stability, small molding shrinkage, etc., are widely used in military industry, automobiles, electronic appliances, etc. The field of application is very wide. But on the one hand, the oxygen index of ABS resin is only 18, which is a flammable material. Therefore, flame retardant modification of ABS resin is a commonly used ABS r...
