Abstract

The invention relates to a flame-retardant ACS composite material. The flame-retardant ACS composite material is composed of, by weight part, 80-100 parts of ACS, 2-4 parts of polyhexafluoropropylene,6-8 parts of flame retardant, 6-8 parts of chlorinated polyvinyl chloride, 0.1-0.3 part of dispersant and 0.1-0.5 part of antioxidant. According to the flame-retardant ACS composite material, the chlorinated polyvinyl chloride achieves self-extinguishment and can produce HCl during combustion, which can shield and dilute combustible gas and block further combustion and accordingly enhance the flame retardance of the flame-retardant ACS composite material; through certain flame retardance of the ACS as well as self-extinguishment of the chlorinated polyvinyl chloride, the flame retardant rating of the ACS can reach V-0 only by adding in a small amount of phosphorous-nitrogen fire retardant of WRO3.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a flame-retardant ACS composite material. Background technique [0002] Styrene-vinyl chloride-acrylonitrile resin (ACS) is one of the most widely used engineering plastics due to its high surface strength, stable size, chemical resistance, good electrical properties, easy molding and processing, and low price. [0003] This application innovatively uses chlorinated polyvinyl chloride to modify ACS, and finally synthesizes a flame-retardant ACS composite material. This material has not been reported so far, which has very important practical significance for expanding the application of ACS composite materials. Contents of the invention [0004] The purpose of the present invention is to provide a flame-retardant ACS composite material to solve the problem of low flame-retardant performance of the ACS composite material in the prior art. [0005] The present inventio...
