Embodiment 1

[0027] A UV-super-matte skin-feeling surface coating method applied to wood coating, the base coating is a conventional UV roller coating process, and the top coating is a UV-super-matte skin-feeling surface coating process, specifically using a special excimer equipment laser roller The equipment adopts UV-ultra-matte skin-feeling surface coating for roller coating, and the coating weight is 25g / m 2 .

[0028] The specific steps of the surface coating process are:

[0029] S1: Laser roller coating to obtain a sufficiently thick paint film and flatness;

[0030] S2: Pre-curing stage, pre-cured by energy-adjustable UV-LED lamp, curing energy is 20%; UV-ultra-matte skin effect coating that can obtain matte effect;

[0031] S3: Cured with an excimer lamp with a wavelength of 172 nm. During the curing process of the excimer lamp, nitrogen is used to isolate the oxygen on the surface of the coated substrate, providing a wrinkled surface, obtaining an ultra-matte gloss, and formin...

Abstract

The invention discloses a UV-ultra-matte skin-feeling surface coating method and a surface coating applied to woodware coating, a conventional UV roller coating process is adopted for bottom coating, a UV-ultra-matte skin-feeling surface coating process is adopted for surface coating, and specifically, special excimer equipment laser roller equipment is adopted for roller coating by adopting the UV-ultra-matte skin-feeling surface coating. The UV-ultra-matte skin-feeling coating is prepared from special raw materials through compatibility of the materials, and then the effects of extinction and skin feeling are achieved in cooperation with special excimer equipment and process. According to the UV-ultra-matte skin-touch coating, in the aspect of selection of UV resin, resin with good elasticity, moderate crosslinking density and good surface curing is selected, the resin can provide a soft framework, meanwhile, the surface curing is good, special excimer curing equipment is matched, after a paint film is cured by an excimer lamp, wrinkled textures are formed on the surface to obtain ultra-matte, the addition amount of matte powder is reduced, and the skin-touch effect is good. The hand feeling of a paint film is greatly improved, and the leveling property of a paint surface is excellent.

Description

technical field [0001] The invention relates to a coating method and a coating, in particular to a UV-ultra-matte skin-feeling top coating method and top coating coating applied to woodware coating. Background technique [0002] As a new material that began to rise in the 1970s, UV-curable coatings have been increasingly widely used because of their fast curing speed, excellent coating performance, energy saving, and solvent-free emissions. The matte coating can give people an elegant and comfortable feeling, and the soft luster can give people a beautiful enjoyment. 95% of furniture and floor coatings in foreign countries are matt coatings, and in China, wood coatings are also moving from bright to matt. [0003] Due to the fast curing and high efficiency of UV curing coatings, the curing and film formation are generally completed within a few seconds. From its coating film-forming mechanism, it can be seen that as long as the double bond is cross-linked to form a film, t...
