Abstract

The invention discloses a non-thickening ultraviolet curing coating material and a preparation method thereof. The coating material comprises the following components in parts by weight: a filler comprising transparent spherical micro-powder and fumed silica micro-powder, and functional aids comprising a dispersing agent, an antifoaming agent, a leveling agent, a photo-initiation aid and a photo-initiator. According to the invention, a diluent is used for reducing the viscosity of a coating material, so that the coating material can be leveled, the cross-linking speed of hydroxyl acrylic resinand polyurethane acrylate is low, and reworking is easy; hydrogen bonds are formed between the diluent and the surface of a coated object, so that the adhesive force is improved, paint removal is prevented, and the structure of double bonds, ester groups and alkane in molecules enables a paint film to have good elongation at break; the dispersing agent disperses the polyurethane acrylate, so thatthe coating material is not easy to thicken; and the filler enhances the roughness of the paint film, lowers the glossiness to achieve the matte effect, and solves the problems in the existing coating material.

Description

【Technical field】 [0001] The invention relates to the technical field of photocurable coatings, in particular to a UV-curable coating that does not return to thickness 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 solvents, high solid content, and high gloss, but there is a problem that it is difficult to extinction. In addition, there are still many requirements for ultra-low matte products that cannot be met, such as high viscosity of the paint, which cannot be recycled, the paint is easy to thicken, does not level, the paint film is easy to return to white after drying, cracking and peeling, and is not scratch-resistant For problems such as rubbing, a new UV-curable coating that can overcome the above-mentioned defects is needed. 【Content of invention】 [0003] The object of the present invention is to provide a non-thickening UV-curable coati...
