Problems solved by technology

In the Chinese patent CN1908060, Bai Jie proposed a method for manufacturing flame-retardant acrylonitrile-styrene copolymer resin / acrylonitrile-chlorinated polyethylene-styrene copolymer resin plastic alloy. The plastic alloy produced by this method has good comprehensive properties, but due to Using rigid acrylonitrile-styrene copolymer resin (SAN) to modify ACS resin, the extrusion processing temperature is high, it is difficult to control, and the production cost is high

Abstract

The invention relates to a fire-retardant ACS/PVC plastic alloy and a manufacturing method thereof. The alloy uses ACS resin and PVC resin as base materials; and compound fire retardant, stabilizer, compatilizer, processing aid, antioxidant and lubricant are added into the base materials in proportion by weight, then the materials are mixed at high speed, and the mixture is blended, extruded and granulated in a double-screw extruder to form the alloy. The prepared fire-retardant ACS/PVC plastic alloy has the advantages of good fire-retardant property, weather resisting property, electrostatic resistance, mechanical property and processing property, can be widely applied in the fields of electron, electrical appliances, communication, instruments, building materials, automobile parts and the like, and is an engineering plastic alloy with good development prospect.

Description

technical field [0001] The invention relates to the technical field of polymer material synthesis, in particular to a flame-retardant ACS / PVC plastic alloy and a manufacturing method thereof. Background technique [0002] ABS resin usually refers to acrylonitrile-polybutadiene-styrene copolymer, which has the characteristics of impact resistance, oil resistance, low temperature resistance, mechanical strength and excellent electrical properties, and is widely used in construction, automobiles, electronics, electrical appliances and Medical equipment and other fields. However, the flame retardant performance of ABS resin is not ideal. Generally, the oxygen index of general-purpose ABS resin is only about 18%, which cannot meet the requirements of flame retardant grade in many applications. [0003] With the development of PVC resin processing technology and the in-depth study of ABS resin modification, it has become a common method to modify ABS resin with PVC resin to impro...
