Abstract

The invention relates to a high-performance extrusion grade ASA resin composition and a preparation method thereof. The preparation method comprises the following steps of: selecting two ASA rubber powders which have high stainability and are composited with different molecular weight and different rubber particle sizes, high molecular weight AS resin, a surface glazing agent, matching with lubricating agent, antioxidant and a weather-proofing agent simultaneously, melting in a twin-screw extruder, blending and preparing the resin composition. The ASA resin composition has high toughness, weathering resistance and surface glossness and good processing performance and is especially applicable to combining extrusion of profiled materials used for buildings of PVC doors and windows and glazed tiles and the like.

Description

technical field The present invention relates to a high-performance extrusion-grade ASA resin composition and a preparation method thereof, in particular to a high-performance extrusion-grade ASA resin composition that can be used for PVC doors and windows or glazed tiles and other architectural profiled materials and its preparation method. technical background PVC plastic doors and windows have been widely popularized and applied in China because of their light weight, corrosion resistance, high strength, heat preservation, sealing and sound insulation, energy saving and environmental protection, easy processing and low cost. Due to the relatively unstable α-C1 in the molecular structure of PVC, the weather resistance of pure PVC processed materials is poor, and it is easily damaged by ultraviolet rays in sunlight outdoors, causing yellowing and redness and other discoloration phenomena. Rutile TiO 2 Has excellent light refraction effect, by adding a certain proportion o...
