Abstract

The invention provides a xanthochromia-resistant UV paint for an external wall sheet material, and a preparation method of the xanthochromia-resistant UV paint, wherein the xanthochromia-resistant UV paint has the properties of good water resistance, good alkali resistance, good washing resistance and good xanthochromia resistance. The xanthochromia-resistant UV paint for the external wall sheet material, disclosed by the invention, consists of the following raw materials in percentage by weight: 30%-40% of an aliphat polyurethane acrylic ester,10%-20% of an acrylic ester,10%-30% of a reactive diluent, 3%-6% of a photoinitiator, 0.1%-2% of a light stabilizer, 0.5%-2% of an auxiliary, and 10%-20% of a mixed solvent. The aliphat polyurethane acrylic ester adopts the polyurethane acrylic ester of which the functionality is 2-4; the acrylic ester is the pure acrylic ester.

Description

technical field [0001] The invention relates to a UV coating and a preparation method thereof, in particular to an anti-yellowing UV coating for exterior wall panels and a preparation method thereof. Background technique [0002] UV coatings are also called Ultra-Violet Ray curing coatings, which mainly cure the coatings to form films through the irradiation of ultraviolet lamps. The application range of ultraviolet wavelengths for industrial use is 200nm-450nm. UV coatings can be applied by roller coating and curtain coating. , spraying and other methods of coating, with low VOC, green environmental protection, fast curing, energy saving, easy industrialization and other advantages. [0003] The exterior wall coatings currently used are basically divided into water-based coatings and solvent-based two-component curing coatings. Water-based coatings dry slowly and have poor performance; solvent-based coatings have high VOC content and are not environmentally friendly. ...
