Embodiment 1～5 and comparative example 1～4

[0040] According to Table 1, formula PC resin, ABS resin, flame retardant, toughening agent, antistatic agent, antioxidant and other additives are put into the mixer and blended until uniform, and the obtained premix is ​​put into the twin screw extruder Melt mixing and extrusion granulation are performed to obtain the antistatic and flame-retardant PC / ABS composite material of the present invention. Among them, the screw length-diameter ratio of the twin-screw extruder is 40:1, the barrel temperature is 260-280°C, and the screw speed is 400-500rpm.

[0041] The antistatic property, flame retardancy and notched cantilever beam impact strength of the prepared PC / ABS composite material were tested. The reference standards or methods for the test are as follows:

[0042] (1) Antistatic property: The surface resistivity is used to characterize the antistatic properties of the material. A 2mm thick molded square plate is adjusted for 24 hours at 23°C and 50% humidity, and the surface re...

Abstract

The invention discloses an antistatic and flame-resistant PC / ABS composite material and a preparation method thereof. The composite material comprises 60-80 parts of PC resin; 8-15 parts of ABS resin; 8-12 parts of flame retardant; toughening agent 1-5 parts; antistatic agent 8-25 parts; antioxidant 0.01-2 parts; other additives 0.4-0.8 parts. The present invention selects the preferred antistatic agent, which minimizes the impact on PC performance, and the use of the antistatic agent in conjunction with the emulsion method ABS is beneficial to the antistatic effect of the antistatic agent and can last.

Description

Technical field [0001] The invention relates to the field of PC / ABS composite materials, in particular to an antistatic and flame-retardant PC / ABS composite material. Background technique [0002] PC / ABS resin is an alloy material with excellent properties. It has excellent physical and mechanical properties, surface hardness, high strength and fluidity, and has a certain degree of heat resistance. It has been widely used in electrical and electronic equipment materials, computers , Mobile phones, printers, housing materials, automotive materials and other industrial parts manufacturing materials. However, the disadvantage of PC / ABS resin is that it has poor flame retardancy and high electrical insulation. Therefore, various modifiers should be added to PC / ABS alloy to improve its performance. Flame retardant PC / ABS alloy is one of them. An important modification direction. [0003] In the semiconductor and automotive industries, the accumulation of static charges can cause perma...
