UV paint

Abstract

The invention discloses a UV coating, which mainly includes the following components, the content of which is expressed in parts by weight: tripropylene glycol diacrylate 10-25; dipentaerythritol hexaacrylate 0-15; acrylate phosphate 3-7 Acrylic resin 10-20; Acrylic acid metal salt 5-15; Photoinitiator 2.0-3.0; Defoamer 0-0.3; Acrylic acid metal salt) as an adhesion promoter, has good adhesion and corrosion resistance on the magnesium alloy oxide layer and passivation layer.

Description

technical field [0001] The invention relates to a UV paint, in particular to a UV varnish with high adhesion. Background technique [0002] UV coatings have the advantages of fast curing speed, energy saving, room temperature curing, superior performance, and environmental protection. The coating speed is fast, the film layer has high brightness, and the film surface is firm and heat-resistant after drying, which can make the surface of the substrate very bright and smooth. , The refraction effect is good, so that the substrate has a strong sense of subject, and has been widely used in chemical industry, machinery, electronics, light industry, communication and other fields. [0003] However, some substances, especially metal substances, have a smooth surface and are sprayed with UV coatings. Due to insufficient adhesion, the spraying effect is not ideal. For example, the surface coating of magnesium alloy is more difficult. The sprayed UV varnish may fall off, which seriou...

Problems solved by technology

[0003] However, some substances, especially metal substances, have a smooth surface. When spraying UV coatings, the spraying effect is not ideal due to insufficient adhesion.

For example, magnesium alloy, its surface coating is more difficult, the sprayed UV varnish may fall off, which seriously affects the appearance effect, and loses the function of UV varnish protective film
