Abstract

The invention discloses a non-thickening ultraviolet curing coating and a preparation method thereof. The coating comprises the following components in parts by weight: fillers include transparent spherical micropowder and fumed silica micropowder, and functional assistants include dispersant, defoamer, leveling agent, photoinitiator assistant and photoinitiator. The thinner is used to reduce the viscosity of the coating so that the coating can be leveled. The crosslinking speed of the hydroxy acrylic resin and the urethane acrylate is slow, and it is easy to rework; the thinner forms a hydrogen bond with the surface of the coating to improve the adhesion and prevent paint stripping. The structure of the double bond, ester group and alkane makes the paint film have better elongation at break; the dispersant disperses the urethane acrylate, and the paint is not easy to thicken; the filler increases the roughness of the paint film and reduces the gloss to achieve a matte effect , to solve the problems existing in existing coatings.

Description

【Technical field】 [0001] The invention relates to the technical field of light-curing coatings, in particular to a non-thickening ultraviolet light-curing coating and a preparation method thereof. 【Background technique】 [0002] At present, the UV-curable coatings on the market basically have the characteristics of no volatile organic solvent, high solid content and high gloss, but there is a problem that it is difficult to extinction. In addition, there are many needs for ultra-low matte products that cannot be met, such as high viscosity of the coating, inability to recycle, easy to thicken the paint, not leveling, easy to white after drying, cracking and peeling, and no scratch resistance. There is a need for a new UV-curable coating that can overcome the above-mentioned defects. [Content of the invention] [0003] The object of the present invention is to provide a non-thickening UV-curable coating, which solves the problems that the existing coating cannot meet the m...
