Example Embodiment

[0011] The manufacturing method of the flame-retardant and impact-resistant ABS composite material of the present invention has the following process steps:

[0012] (1) First, put 20-40 parts by weight of glass fiber and 10-14 parts by weight of hollow glass beads into the solid mixer, and spray the silane coupling agent solution directly on the glass fibers and hollow glass beads and stir. Use high speed to achieve good dispersion effect. After stirring for 10-30 minutes, dry at 120°C for about 2 hours;

[0013] (2) Mix the processed glass fibers and glass beads with 100 parts by weight of ABS resin, 50-80 parts by weight of PC resin, and 2-4 parts by weight of lubricant under stirring, and then pass the feeding device Feed into the twin-screw extruder, under the heating, shearing, and mixing of the screw, the material can be fully melted, and then extruded, drawn, cooled, and pelletized into finished products.

[0014] The length-diameter ratio of the twin-screw extruder of the ...

Abstract

The invention provides a manufacturing method for flame-resistant impact resistant ABS (acrylonitrile-butadiene-styrene) composite material, the process of the manufacturing method is as follows: 20 to 40 weight portions of glass fiber and 10 to 14 weight portions of hollow glass microspheres are put into a solid blender; a silane coupling agent solution is directly sprayed on the glass fiber and the hollow glass microspheres to be stirred; high revolving speed is adopted so as to achieve good disperse effect. The mixed material is stirred for 10 to 30 minutes and dried at the temperature of 120 DEG C for about two hours; then the treated glass fiber and the hollow glass microspheres are stirred and fully mixed with 100 weight portions of ABS resin, 50 to 80 weight portions of PC resin and 2 to 4 weight portions of lubricating agent, then the mixture is fed to a double screw extruder by a feeding device; and the mixture material is fully molten through temperature rising, shearing and mixing of a screw rod, and then is squeezed out, braced, cooled and palletized to finished products. The manufacturing method has high production efficiency; and the product has excellent properties.

Description

technical field [0001] The invention relates to a method for manufacturing an ABS composite material, in particular to a method for manufacturing a flame-retardant and impact-resistant ABS composite material. Background technique [0002] ABS engineering plastics are adopted by most notebook computer manufacturers due to their low cost. At present, most notebook computers with plastic casings use ABS engineering plastics as raw materials. There are many kinds of ABS flame retardant materials currently sold on the market, and there are roughly two types related to the present invention: (1), PC / ABS alloy flame retardant materials: combining the strength and toughness of PC and the ease of processing of ABS, mainly It is used in the manufacture of shells in the fields of electronic appliances, communication equipment, automobiles, computers, office business machines, etc. But the biggest disadvantage is heavy weight, poor thermal conductivity, and high cost. (2) Glass fiber ...
