Problems solved by technology

The process of white PU as the base and transparent UV paint as the top coat is often accompanied by the volatilization of harmful substances during the production process, which seriously affects the health of the body, and the production cycle is long, prone to cracking, orange peel and other problems; roll coating White UV is used as a primer, and then transparent UV is used as a topcoat process. Although the environmental protection and bursting problems have been solved, the problem that white is the most prone to yellowing has not been solved.

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with examples, which are only preferred implementations of the present invention, and are not limitations of the present invention.

[0027] The construction technique of the present invention is on base materials such as white melamine base material.

[0028] The UV primer, UV color paint, and high-gloss UV topcoat used in the embodiments of the present invention are all commercially available products. And the allocation of various lacquers all adopts the method that this area usually adopts.

[0029] A high-gloss white UV coating construction process, comprising the following steps:

[0030] a) Sanding the base material;

[0031] b) Roller UV primer, the coating amount is 17~25 g / m 2 , and then use a single mercury lamp for ultraviolet light drying, the mercury lamp intensity is 280~320 mj, and the drying time is 1~3 seconds;

[0032] c1) Roller coating of pure white UV primer, the coating amo...

Abstract

The invention relates to the coating application technology, in particular to a high gloss white UV (Ultra Violet) coating application technology. The gloss white UV coating application technology comprises the following steps of hair sanding; roller coating UV priming paint; roller coating pure white UV priming paint; roller coating sanding UV priming paint; sanding and dedusting; shower coating transparent UV priming paint; moistening before shower coating; shower coating pure white highlight UV finishing paint; coating a film after drying. The application technology is dispense with spray coating, has no paint mists and is in batch production; since UV white paint is utilized for shower coating the surface of a plate, the color is very uniform, and the adhesive force is strong; most important is that transparent gloss paint is not used on the surface, so that the coating has strong resistance to yellowing, is non-discolouring basically, and has the grade of fifth level.

Description

[0001] technical field [0002] The invention relates to a paint construction technology, in particular to a high-brightness white UV coating construction technology. [0003] Background technique [0004] At present, the high-gloss white UV decorative panels on the market are generally made of white PU as the base, sprayed with transparent UV paint as the top coat or roller coated with white UV as the primer, and then poured with transparent UV as the top coat. The process of white PU as the base and transparent UV paint as the top coat is often accompanied by the volatilization of harmful substances during the production process, which seriously affects the health of the body, and the production cycle is long, prone to cracking, orange peel and other problems; roll coating Although white UV is used as a primer, and then transparent UV is used as a topcoat process, although the problems of environmental protection and bursting have been solved, the problem that white is th...
