Embodiment 1

[0031] Prepare materials according to the following weight ratio:

[0032] 60 parts of PC resin,

[0033] 40 parts of ABS resin,

[0034] 1 part anti-wear agent,

[0035] Antioxidant 0.3 part,

[0036] Lubricant 0.3 part,

[0037] 1) Add PC resin, ABS resin, wear-resistant agent, antioxidant and lubricant into the mixing mixer;

[0038] 2) Then, the mixture is blended and granulated by a twin-screw extruder to obtain wear-resistant PC / ABS alloy particles. The barrel temperature of the extruder is 240-280° C., and the screw speed is 400-600 rpm.

Abstract

The invention relates to a wear-resisting PC (polycarbonate) / ABS (Acrylonitrile butadiene styrene) alloy material and a preparation method thereof. The wear-resisting PC / ABS alloy material is prepared by the following raw materials according to weight portion: 50 to 80 portions of PC resin, 20 to 50 portions of ABS resin, 1 to 10 portions of wear-resistant agent, 0.1 to 1 portion of antioxidizer, and 0.1 to 1 portion of lubricator, wherein a PE-g-MAH (maleic anhydride) copolymer is adopted as the wear-resistant agent, and the content of the MAH accounts for 1 to 3 percent according to weight percentage. According to the invention, the PE-g-MAH copolymer is adopted as the wear-resistant agent, the wearing resistance of the surface of the PC / ABS alloy material is improved obviously, the defect of wearing resistance deficiency caused when the PC / ABS alloy material is adopted as spraying-free material can be overcome, and an important significance to the application of the PC / ABS alloy material in the field of spraying-free work pieces is played.

Description

technical field [0001] The invention relates to a modified resin, in particular to a wear-resistant PC / ABS alloy material and a preparation method thereof. Background technique [0002] Due to its excellent comprehensive performance, PC / ABS alloy materials are widely used in industries such as automobiles, home appliances, communications and IT. The trend has made PC / ABS alloy materials widely used in the automotive industry. [0003] For a long time, people are accustomed to post-processing PC / ABS alloy materials, such as spraying, water transfer printing, etc. However, with the improvement of people's awareness of environmental protection and the promulgation of ELV regulations for automobiles, more thermoplastic materials are required to be recycled directly without the process of separating thermosetting paint films. So people began to devote themselves to the research of spray-free materials, but due to the poor wear resistance of PC / ABS, its application as a spray-fr...
