Abstract

Provided is a PC-ABS alloy for a thin-wall product and a preparation method of the thin wall product PC-ABS alloy. The PC-ABS alloy comprises, by weight, 30-90 parts of PC, 15-60 parts of ABS, 2-20 parts of LLDPE and 0.5-10 parts of lubricant. Through adding the flow modifier compounding linear low density LLDPE and lubricant in the PC-ABS material, the method hugely increases the melting point of the PC-ABS alloy, thus making the die stamping of the injection molding process of thin-wall product smooth, making the product fusion connection strength high and not prone to break.

Description

technical field [0001] The invention relates to a PC-ABS alloy and a preparation method thereof, in particular to a PC-ABS alloy used for thin-walled products and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the automobile industry and the communication industry, the lightweight of related products and the development trend of replacing steel with plastic are also accelerating. The application of PC-ABS alloy materials in these industries has also ushered in new opportunities. Since the mid-1960s, the United States BorgWarner Chemicals developed the first PC-ABS alloy. The PC-ABS alloy with PC and ABS as the main raw materials has become an important engineering plastic alloy. After that, many PC-ABS alloys have been developed successively. ABS alloy products, such as flame retardant PC-ABS, glass fiber reinforced PC-ABS and other categories. [0003] PC-ABS is a modified engineering plastic synthesized by mixing...
