Embodiment 1

[0023] In Example 1, the anti-wear agent and polytetrafluoroethylene (PTFE) prepared by the present invention were not added.

[0024] The preparation method of the alloy material of this embodiment is specifically as follows:

[0025] 1) Weigh ABS840g, PMMA150g, antioxidant 2g, lubricant 4g, and silicone oil 10g for use;

[0026] 2) Add ABS, PMMA, and silicone oil to a high-speed mixer and mix for 5 minutes, then add antioxidants and lubricants in sequence and mix well;

[0027] 3) The mixture obtained in step 2) is added to a co-rotating twin-screw extruder for extruding and granulating at a speed of 300-400r / min and a temperature of 210-235°C. After cooling in a water tank, the mixture is cut into ABS alloy materials.

Abstract

The invention provides a high-rigidity wear-resistant ABS (acrylonitrile-butadiene-styrene) alloy material which comprises the following components in parts by mass: 50-85% of ABS, 10-40% of PMMA (polymethyl methacrylate), 0-5% of PTFE (polytetrafluoroethylene), 0-5% of self-made anti-wear agent, 0-5% of organic silicone oil, 0.2-1% of lubricant and 0.2-1% of antioxidant. The high-rigidity wear-resistant ABS alloy material has the advantages of high surface hardness, small friction factor, high gloss, favorable toughness and the like; and the preparation method of the alloy material is simple in manufacturing procedure and low in composite cost. Thus, the invention is especially applicable to the industries of electronics / electrical appliances, home appliances and the like.

Description

Technical field [0001] The invention belongs to the technical field of plastic alloy preparation, and specifically relates to an ABS alloy material and a manufacturing method. Background technique [0002] ABS resin is a terpolymer (acrylonitrile-butadiene-styrene) developed on the basis of polystyrene (PS) resin modification. It is a kind of good quality between engineering plastics and general plastics. Thermoplastic resin with comprehensive properties and easy processing and molding. ABS resin has the advantages of high gloss, easy molding, impact resistance, etc., and its application in household appliances, chemicals, automobiles, electronic appliances and other fields has become more and more extensive, so the demand is growing rapidly. However, ABS resin itself has many performance deficiencies and defects, such as self-lubricity, wear resistance, heat resistance, weather resistance, and poor surface hardness, which hinder and limit the further application of ABS resin. ...
