Abstract

The invention provides a UV (ultraviolet) roller-coating metal high-adhesion yellowing-resistant primer which comprises the following components in percentage by weight: 30-41% of functional monomer, 12-19% of polyacrylate, 19-25% of epoxy acrylic resin, 0.3-0.4% of defoaming agent, 0.2-0.3% of leveling agent, 0.5-1% of functional assistant, 2-4% of silane coupling agent, 0.2-0.4% of anti-settling agent, 10-15% of filler and 9-12% of photoinitiator. The UV roller-coating metal high-adhesion yellowing-resistant primer provided by the invention has the advantages of high adhesive force, favorable yellowing resistance, low cost, high drying rate, no waste and high production efficiency, and is simple and flexible to operate.

Description

technical field [0001] The invention relates to a UV roller clear primer, in particular to a high adhesion anti-yellowing primer coating applied on a metal surface. Background technique [0002] According to the popular trend of home decoration, and in order to beautify the design and the surrounding environment, many cabinets, decorative materials and some buildings now adopt the method of metal skinning. The advantages of this method are high-grade, cheap, fireproof, Waterproof, long service life, various and fashionable colors and shapes, etc., the disadvantages are poor paint adhesion, difficult repair after damage, fading after construction and outdoor time for a long time. Therefore need to provide a kind of high adhesion anti-yellowing primer coating that is coated on the metal surface. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the existing technology, to provide a UV roller coating metal high adhesio...
