Problems solved by technology

[0003] Although the existing pearlescent paint is a water-based system, it adopts thermal curing, the curing speed is slow, the temperature and humidity of the construction are high, and there is a large amount of VOC emissions. The construction will cause serious air pollution and high energy consumption. And the surface properties of the cured coating film are poor

Abstract

The invention provides a UV (Ultraviolet) cured pearly luster coating which comprises the following components in parts by weight: 45-65 parts of a light-cured resin, 5-20 parts of a light-cured active monomer, 1-10 parts of a photoinitiator, 1-5 parts of a sensitizer, 0.1-0.5 part of a lubricant, 0.1-0.5 part of a defoaming agent, 0.5-2 parts of rheological additives, 3-6 parts of a mica pearly luster pigment and 0.1-0.5 part of a dispersant. The invention further provides a preparation method of the UV cured pearly luster coating. The pearly luster coating provided by the invention can be cured with UV, is high in curing speed, low in energy consumption, good in environment protection, low in VOC (Volatile Organic Compound), high in construction efficiency, low in construction cost, excellent in coating mechanical property, good in weather resistance and good in scratch resistance.

Description

technical field [0001] The invention relates to a UV curing pearlescent coating and a preparation method thereof. Background technique [0002] Pearlescent paint has a dazzling decorative effect. At present, the automobile, jewelry, and 3C manufacturing industries have widely used pearlescent paint for decoration. [0003] Although the existing pearlescent paint is a water-based system, it adopts thermal curing, the curing speed is slow, the temperature and humidity of the construction are high, and there is a large amount of VOC emissions. The construction will cause serious air pollution and high energy consumption. And the surface properties of the cured coating film are poor. Contents of the invention [0004] The object of the present invention is to provide a kind of UV curable pearlescent coating and preparation method thereof, the pearlescent coating of the present invention can adopt UV curing, curing speed is fast, energy consumption is low, environmental protec...
