Abstract

The invention relates to a PC / ABS alloy with noise reduction performance and a preparation method of the PC / ABS alloy. The alloy is prepared from, by weight, 40-80 parts of PC, 20-45 parts of ABS, 0.5-5 parts of compatilizer, 1-10 parts of noise reduction master batch, 2-10 parts of flexibilizer, 0.1-1 part of antioxidant and 0.1-1 part of lubricating agent. The materials are prepared according to the components and weight parts and placed into a medium-speed mixer to be mixed for 5-30 min to obtain a mixed material, finally, the mixed material is placed into a double-screw extruder, the screw rotating speed is controlled to be 180-600 rpm, melt extrusion and pelleting are carried out, and therefore the product is obtained. Compared with the prior art, the PC / ABS material with the noise reduction performance has the good physical property and has the good noise reduction effect.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PC / ABS alloy with noise reduction performance and a preparation method thereof. Background technique [0002] PC / ABS alloy is an amorphous engineering plastic with excellent impact strength, heat resistance, high rigidity and other properties, and is widely used in automobiles, electronics, home appliances and other fields. Due to the increasing use of plastic parts in automobiles, the requirements for automobiles are getting higher and higher, and the requirements for the environment and noise in the car are also getting higher and higher. Therefore, in many applications, PC / ABS alloy needs to have better sound insulation and noise reduction effect, and better provide a comfortable and quiet environment in the car. [0003] At present, there is no PC / ABS alloy that can reduce noise in the industry. Other related industries mainly use composite materials or multi-layer extrusi...
