Problems solved by technology

[0006] The problem with the PC-ABS resin alloy disclosed in ZL200610035661.3 is that its impact strength index is 35-43KJ / m 2 During use, it was found that the electronic product shell made of the aforementioned materials, the embedded part is often broken during maintenance and disassembly. Obviously, such an impact strength index cannot meet the application needs of some electronic product shells, such as obviously meeting Can not be used as a mobile phone shell material, and at the same time, the cost is relatively high. According to the above, it is obvious that there is a need for further improvement in the existing technology

Abstract

The invention discloses an improved PC-ABS (polycarbonate-acrylonitrile-butadiene styrene) resin alloy. The improved PC-ABS resin alloy is characterized by comprising the following components in parts by weight: 60 parts of polycarbonate, 25 parts of acrylonitrile-butadiene styrene, 1 to 20 parts of flexibilizer, 1 to 10 parts of stress-resistant cracking agent, 0.1 to 5 parts antioxidant of and 0.1 to 5 parts of flowable agent, wherein the flexibilizer is selected from at least one of ethylene-1-octene copolymer, ethylene-butylene copolymer, ethylene-propylene polymer and styrene-butadiene copolymer; and the stress-resistant cracking agent is selected from at least one of ethyl-hydrogenated nitrile-acrylate ternary polymerized graft and crylic acid grafted polyolefin elastomer copolymer. On the basis that the other performance indexes of the prior art are maintained, the impact strength is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to an improved PC (Polycarbonate, polycarbonate)-ABS resin alloy and a production method thereof, belonging to the field of thermoplastic resin compositions in polymer material technology. Background technique [0002] PC-ABS resin alloy is polycarbonate and acrylonitrile-butadiene-styrene copolymer and mixture, it is a thermoplastic plastic made of polycarbonate (Polycarbonate) and polyacrylonitrile (ABS) alloy, in PC- In ABS resin alloys, the content of PC is generally greater than 50%.
