Abstract

The invention belongs to the technical field of PVC material preparation, and particularly relates to a PVC and ASA co-extrusion profile and a preparation method thereof. The PVC and ASA co-extrusionprofile comprises a core layer and a skin layer, and is prepared from the core layer raw materials: 75 parts by mass of PVC resin, 20-60 parts by mass of a filling material, 3-5 parts by mass of a heat stabilizer, 1-3 parts by mass of a light stabilizer, 0.2-0.5 part by mass of an ultraviolet light absorber, 0.5-1 part by mass of an antioxidant, 2-5 parts of an anti-ultraviolet modifier, 0.3-1 part by mass of a lubricant, 0.5-2 parts by mass of a processing aid and 0-3 parts by mass of a pigment, and skin layer raw materials: 10-20 parts by mass of ASA resin granules. The prepared co-extrusionprofile has high weather resistance and mechanical property, does not fade and is good in electrical insulating property; meanwhile, the invention further provides the preparation method of the co-extrusion profile, a skin layer structure and a core layer structure can be obtained by the preparation method, the thickness of the co-extrusion layer can be smaller, and the product is more attractive.

Description

technical field [0001] The invention belongs to the technical field of PVC material preparation, and in particular relates to a PVC and ASA co-extrusion profile and a preparation method thereof. Background technique [0002] Polyvinyl chloride, referred to as PVC, is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. Polyvinyl chloride has been widely used in various products in various industries. As an emerging chemical building material, polyvinyl chloride has become an indispensable new building material in my country's construction industry because of its characteristics of energy saving, heat insulation, heat preservation, environmental protection, and easy installation. As a kind of PVC plastic profiles, PVC co-extruded profiles are in increasing market demand due to their rich colors or excellent weather resistance. [0003] ASA resin, also known as AAS resin, is a ternary graft copolymer composed of acrylonitrile (A), styrene (S) ...
