Abstract

The invention relates to an extrusion-grade inflaming retarding ACS (acrylonitrile-chlorinated polyethylene-styrene) resin. The resin is characterized by comprising the following components in parts by weight: 100 parts of ACS resin, 15-25 parts of brominated inflaming retarding agent, 3-6 parts of super-fine antimonous oxide, 0-10 parts of flexibilizer, 1-5 parts of melt strength regulator, 3-6 parts of thermal stabilizer, 0.5-1.5 parts of lubricant, 0.5-2 parts of antioxidant and 0.1-1.0 part of weather resisting agent. The extrusion-grade inflaming retarding ACS resin provided by the invention can be compounded and co-extruded with PVC (polyvinyl chloride) and has uniform coating, good surface gloss and smooth section, and the maximum processable width of the resin is greatly improved.

Description

Technical field [0001] The invention relates to the field of polymer modification, and specifically refers to an extrusion-grade flame-retardant ACS resin and a preparation method thereof. Background technique [0002] PVC plastic doors and windows have been widely used in China because of their light weight, corrosion resistance, high strength, energy saving, sound insulation, easy processing and low cost. Compound co-extrusion is one of the main methods of colorization of PVC profiles. By co-extruding a layer of color co-extrusion material with a thickness of 0.2mm~0.5mm on the surface of PVC profiles, the product is bright in color and beautiful in appearance. Commonly used co-extrusion raw materials are PVC, ASA and PMMA, but due to the poor weather resistance of PVC itself, more choices are ASA and PMMA as co-extrusion raw materials. [0003] PMMA has excellent weather resistance and high coloring performance. However, due to its poor flowability, it is difficult to form a un...
