Abstract

The invention discloses a hydrolysis-resistant, halogen-free flame-retardant, high-toughness PC / ASA alloy material and its preparation method and application. The PC / ASA alloy material comprises the following components: PC base resin, phosphazene flame retardant, Toughening masterbatch, anti-dripping agent, dispersant; wherein, the toughening masterbatch includes PC carrier resin, ASA resin and toughening agent. In the present invention, by controlling the compounding of the toughening agent and the rubber size and particle size in the ASA resin, and pre-blending the phosphazene flame retardant and the PC base resin, adding the toughening master batch for modification, the prepared PC / ASA The alloy material also has high toughness, high temperature hydrolysis resistance and excellent flame retardancy, and can be widely used in the preparation of automobiles and electrical products.

Description

technical field [0001] The invention relates to the technical field of alloy modification, in particular to a hydrolysis-resistant, halogen-free flame-retardant, high-toughness PC / ASA alloy material and its preparation method and application. Background technique [0002] Polycarbonate / acrylonitrile-styrene-acrylate copolymer (PC / ASA) alloy is a material that combines good toughness, good temperature resistance of PC and good processing performance of ASA, good chemical resistance and good weather resistance. been extensively studied in recent years. In order to meet the technical update and change requirements of this material in the application, the PC / ASA composition should have good flame retardancy, high toughness and high temperature hydrolysis stability to ensure that the material can be safe in some severe environments. service. [0003] Patent CN109486147A discloses an anti-drawing flame-retardant PC-ASA alloy, by adding one or more of organic phosphorus flame ret...
