Abstract

The invention belongs to the field of polymers, aiming at the problems of low impact strength and poor fluidity of a prior AS / CPVC alloy material, the invention provides an AS / CPVC alloy material withhigh impact strength and high fluidity, which consists of, by weight, 40-60 parts of AS resin; 40-60 parts of CPVC resin; 5-15 parts of a toughening agent; 4-8 parts of a compatilizer hyperbranched polystyrene-maleic anhydride; 2-8 parts of a flame retardant; 1-3 parts of a stabilizer; 0.1-0.5 part of an antioxidant; 0.5-2 parts of a lubricant; 1-2 parts of a processing aid; 1-3 parts of C5 / C9 copolymer petroleum resin as a flow modifier. The invention also provides a preparation method of the alloy material, which comprises the following steps: mixing the CPVC resin powder, the toughening agent, the compatilizer, the lubricant and the antioxidant, and then adding the processing aid and the flow modifier; adding the AS resin into a double-screw extruder from a main feeding port, adding premix from a side feeding port, and extruding and granulating. The AS / CPVC alloy material prepared by using hyperbranched polystyrene-maleic anhydride as the compatilizer has high impact strength, highfluidity and wide application space.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an acrylonitrile-styrene copolymer / chlorinated polyvinyl chloride alloy material and a preparation method thereof. Background technique [0002] Acrylonitrile-styrene copolymer (AS) is a synthetic resin formed by copolymerizing two monomers of acrylonitrile (AN) and styrene (ST). It has good mechanical properties and processing properties, but is brittle. Flammable, which limits its scope of application; chlorinated polyvinyl chloride resin (CPVC) is a product obtained after further chlorination and modification of polyvinyl chloride resin, and its chlorine element mass content range is usually 62% to 69%. It has excellent flame retardancy, heat resistance, weather resistance, etc., but it has high viscosity and is not easy to process. Although the alloy material modified by the blending of the two resins has excellent flame retardancy and heat resistance, ...
