Abstract

The present invention relates to a mass polymerization compound of an acrylonitrile- butadiene-cinnamene and poly-terephthalic acid butanediol lipid, which is characterized by consisting of the following weight percentage compositions of materials: 30-70 percent of mass polymerization acrylonitrile- butadiene-cinnamene (ABS) resin, 5-30 percent of poly-terephthalic acid butanediol lipid (PBT) resin, 2-8 percent of compatibilizer, 0.5-5 percent of heat resisting modifier and 10-35 percent of glass fibre, and the manufacturing method thereof is characterized in that under the high speed cut, milling and delivery of a screw, the material can be melted and compounded sufficiently, and the final product can be achieved after fusing, extruding a stray, cooling, pelleting and drying. The advantage of the present invention is to obtain the performance, such as high intension, fatigue resistance, shock resistance, of the mass polymerization acrylonitrile- butadiene-cinnamene (ABS), extending the application range of the mass polymerization acrylonitrile- butadiene-cinnamene (ABS).

Description

technical field [0001] The invention relates to a bulk-process acrylonitrile-butadiene-styrene and polybutylene terephthalate compound and a preparation method thereof, which has high heat resistance, high rigidity, fatigue resistance, stable size and warpage prevention, etc. function, can be applied to home appliances, IT, auto parts, and belongs to the technical field of chemical materials. Background technique [0002] Acrylonitrile-butadiene-styrene (ABS) resin combines the characteristics of general-purpose synthetic resins and engineering plastics, has high impact strength, heat resistance and dimensional stability, excellent comprehensive performance, and is easy to process.
