ABS (Acrylonitrile-butadiene-styrene) alloy particle and preparation method thereof

Abstract

The invention relates to the field of alloy materials, and provides an acrylonitrile-butadiene-styrene (ABS) alloy particle which is prepared from the following raw materials in parts by weight: 40-60parts of ABS, 40-60 parts of polyvinyl butyral (PVB), 5-7 parts of maleic anhydride-grafted acrylonitrile-butadiene-styrene (ABS-g-MAH), 3-4 parts of nanometer calcium carbonate, 1-3 parts of white mineral oil, and 1-3 parts of a smoke suppressant, wherein PVB is specifically derived from PVB waste of production and life. The invention also provides a method for preparing ABS alloy particle. TheABS alloy particle has the advantages that the ABS wastes and the PVB wastes are used together, and a corresponding lubricant, the smoke suppressant, a toughening agent and a compatibilizer are properly matched, so that the finally obtained ABS / PVB modified alloy is more excellent, and the application range of the ABS alloy is further expanded. In addition, the PVB waste is used in the preparationof the ABS alloy particles, and can further reduce environmental pressure.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to an ABS alloy particle and a preparation method thereof. Background technique [0002] ABS has a special structure consisting of a plastic phase and a rubber phase, which determines its superiority in performance, such as good rigidity, toughness, oil resistance, corrosion resistance, and good processing fluidity. It is widely used in automobiles and home appliances. In all walks of life, but it also has the disadvantages of poor heat resistance, no flame retardancy and higher cost than general-purpose plastics. The phenyl and cyano groups in the ABS structure provide good conditions for the modification of ABS. There have been a large number of ABS blended modified varieties, such as PVC / ABS, PC / ABS, PBT / ABS and PMMA / ABS, etc. They have their own strengths in performance, and gradually replace some plastic varieties, and appear in people's lives.
