Problems solved by technology

However, the adhesion between the ultraviolet resin in this pearl paint ultraviolet coating and the color powder in the colored pigment is not good, making it difficult to control the color of the coating
In addition, due to the light-shielding properties of the color powder, ultraviolet light cannot penetrate to the deep layer of the coating, making it difficult to fully cure the coating

Embodiment Construction

[0018] In order to further elaborate the technical means and effects that the present invention adopts to achieve the intended purpose of the invention, a kind of colored coating for photocuring is proposed according to the present invention, and its specific implementation, features and effects are described in detail as follows: Rear.

[0019] The photocurable colored coating of the present invention, wherein the colored coating includes a photoinitiator, an ultraviolet resin, and an ultraviolet sensitive fluorescent powder.

[0020] The photoinitiator can absorb the radiant energy of the curing light, and can induce the polymerization of the colored coating during the curing process, and has the characteristics of good thermal stability. For example, the photoinitiator is p-methoxyphenylacetone (molecular formula C 10 h 12 o 2 ), 9-phenylacridine (molecular formula: C 19 h 13 N), N-phenylglycine (molecular formula: C 8 h 9 NO 2 )...or others etc.

Abstract

The present invention provides a light curable colored coating, comprising a photoinitiator, a UV resin and a UV photosensitive phosphor, wherein the light curable colored coating is formed by mixing and then separating the photoinitiator, the UV resin and the UV photosensitive phosphor, wherein the mixture is applied to a substrate thereafter, and thus the curing time of the light curable colored coating is largely shortened.

Description

technical field [0001] The invention relates to a colored paint, in particular to a colored paint for photocuring. Background technique [0002] Coatings are widely used on the surface of substrates such as electronic products, building materials, automobiles, etc., in order to achieve the effect of decoration or protection. However, the coatings in the prior art must go through repeated spraying processes to evenly adhere to the casing of electronic products, and after each spraying process, they need to be baked at high temperature, and the next spraying process can only be carried out after the paint is dry. , so it consumes a lot of process time and energy. [0003] In addition, there are also companies in the industry who have developed a pearl varnish UV coating, which is cured on the casing of electronic products with UV light after a spraying process. However, the adhesiveness between the ultraviolet resin in the pearl lacquer ultraviolet coating and the color powd...
