A pc/abs material with high binding force and easy electroplating and its preparation method

Abstract

The invention relates to a PC / ABS material with high binding force and easy to electroplate and a preparation method thereof. The PC / ABS material is prepared from the following components by a weight ratio: 33.4 to 61.3 percent of PC, 20 to 30 percent of ABS, 15 to 30 percent of modified carbon fiber, 3 to 5 percent of compatilizer, 0.2 to 0.5 percent of dispersant, 0.3 to 1 percent of antioxidant and 0.2 to 0.5 percent of lubricant. The preparation method of the PC / ABS material comprises the following steps of mixing all the components into a mixing agitator according to a proportion to carry out mixing; blending and granulating an obtained mixture through a twin screw extruder. The method provided by the invention is simple, easy and feasible; the dispersion, in a PC / ABS matrix, of the carbon fiber is promoted through the introduction of the compatilizer, so that the excellent electric conduction performance can be given to a PC / ABS alloy composition through a minute quantity of the carbon fiber; the linear expansion coefficient of the composition is decreased; an electroplating procedure can be directly carried out; coarsening, activating and chemical plating procedures are omitted; the electroplating procedure is simplified; a product composition provided by the invention has high mechanical strength; further, the dimensional stability is good.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PC / ABS material with high binding force and easy electroplating and a preparation method thereof. Background technique [0002] At present, the casing materials of office supplies are mostly PC resin, ABS resin or PC / ABS composite resin. However, PC resin has high melt viscosity, difficult processing and molding, especially large-scale products are prone to stress cracking, poor chemical resistance, and high price. These deficiencies limit the application of PC to a certain extent; the performance of ABS resin is between engineering Between plastics and general-purpose plastics, it has good impact resistance and processing performance, and the price is relatively cheap, so it has been widely used. However, its heat resistance and weather resistance are poor, and its mechanical properties are not ideal. The PC / ABS alloy with PC and ABS as the main raw materials is an...

However, PC resin has high melt viscosity, difficult processing and molding, especially large-scale products are prone to stress cracking, poor chemical resistance, and high price. These deficiencies limit the application of PC to a certain extent; the performance of ABS resin is between engineering Between plastics and general-purpose plastics, it has good impact resistance and processing performance, and the price is relatively cheap, so it has been widely used.

However, its heat resistance and weather resistance are poor, and its mechanical properties are not ideal.

The PC / ABS alloy with PC and ABS as the main raw materials is an important engineering plastic alloy, which has the characteristics of good processing formability, corrosion resistance and toughness, but its heat resistance and weather resistance are poor, and its mechanical properties are not ideal.

Moreover, PC is the main component of PC / ABS alloy materials, which results in a significant reduction in the number of electroplating points of PC / ABS materials, reduces its electroplatability, coating bonding strength and other properties, and cannot meet the increasingly higher performance requirements of electroplating products.
