Abstract

The invention discloses a highly-weather-resistant type ASA (acrylonitrile Styrene acrylate copolymer)-based color co-extrusion material with low heat absorption effect and a preparation method thereof. The highly-weather-resistant type ASA-based color co-extrusion material is characterized by comprising the following components in parts by weight: 85-94 parts of ASA, 1-4 parts of a light stabilizer, 1-2 parts of an ultraviolet absorber, 1-3 parts of an antioxidant and 2-6 parts of pigments. The preparation method of the highly-weather-resistant type ASA-based color co-extrusion material comprises the following steps: (1) weighing base stock, the light stabilizer, the ultraviolet absorber, the antioxidant and the pigments in proportion; (2) firstly adding the light stabilizer, the ultraviolet absorber, the antioxidant and the pigments to uniformly mix, and then adding the base stock to uniformly mix; and (3) extruding and pelletizing the uniformly-mixed materials to prepare the highly-weather-resistant type ASA-based color co-extrusion material with low heat absorption effect. Compared with the prior art, the highly-weather-resistant type ASA-based color co-extrusion material has low heat absorption and more superior weather resistance.

Description

technical field [0001] The invention belongs to a high-weather-resistant color co-extrusion special material used for PVC profiles and a preparation method thereof, in particular to a high-weather-resistant color co-extrusion material with low heat absorption effect and a preparation method thereof. Background technique [0002] At present, PVC profile products occupy a very important position in doors and windows, especially in recent years, the energy-saving and environmental protection policy implemented by the national building materials, PVC profile has been widely used all over the country. With the improvement of living standards, people are increasingly pursuing the colorization and differentiation of doors and windows. In recent years, the colorization of PVC profiles has been vigorously promoted and supported by relevant national departments and profile industry associations. [0003] In recent years, the colorization of PVC profiles has developed rapidly, and colo...
