ACS ALLOY, PREPARATION METHOD THEREFOR AND USE THEREOF

The present invention relates to the technical field of engineering plastics, and in particular to an ACS alloy, a preparation method and a use thereof. According to the present invention, a SAN resin and chlorinated polyethylene (CPE) are blended and extruded to form an ACS alloy; a compatibilizer used is ABS high-rubber powder having a core-shell structure, which can improve the compatibility of SAN and the CPE, and can also improve the impact properties of the ACS alloy; nano hydrotalcite is used as a heat stabilizer, and hydrotalcite (LDHS) is a basic magnesium aluminum carbonate layered compound and is porous, and thus can improve the thermal stability of the ACS alloy and has small damage to the mechanical properties of the ACS alloy; the stability of electrical properties of the ACS alloy can be improved while improving the flame retardancy thereof; and the ACS alloy having excellent mechanical properties, excellent weather resistance, excellent flame retardancy and excellent electrical properties is o
