Abstract

The invention discloses a single-component water-based UV protection coating material for polyvinyl chloride and a preparation method thereof. The single-component water-based UV protection coating material is special functional assistant-containing aqueous emulsion of an acrylic ester copolymer. When used, the aqueous emulsion is sprayed on the surface of a polyvinyl chloride product; and after the aqueous emulsion is solidified, the uniform photoprotection coating material is formed. Results of experiments show that the polyvinyl chloride product of the single-component environmental-friendly water-based UV protection coating material provided by the invention has obviously improved UV stability, greatly improved mechanical property long-term conservation rate and obviously improved appearance color stability.

Description

technical field [0001] The invention relates to the technical field of polymers, more specifically to an ultraviolet light protective coating material for polyvinyl chloride, and a preparation method for the ultraviolet light protective coating material. technical background [0002] In the field of chemical building materials in my country, the amount of polyvinyl chloride has always ranked first. However, when used outdoors, under the influence of ultraviolet light as the main cause, PVC molecules will undergo a series of physical and chemical changes, which will lead to performance degradation such as hardening, brittleness, discoloration, and pulverization of the product. eventually loses its use value. Therefore, the poor UV resistance of polyvinyl chloride has become one of the main obstacles restricting its healthy development. [0003] The most commonly used method to improve the light resistance of polyvinyl chloride is to add a certain amount of organic ultraviol...
