Abstract
The invention belongs to the technical field of coatings and particularly relates to a colorful LED-UV glass coating and a preparation method thereof. The coating is prepared from modified aliphatic acrylate, modified epoxy acrylate, modified polyester acrylate, a glass surface adhesion promoter, a compound photoinitiator, nano zirconia, a boiling resistant aid, a defoaming agent, a leveling agent, graphene, pigment and a diluent. The glass surface adhesion promoter capable of improving glass surface adhesion as well as resin, the initiator and various aids capable of improving boiling resistance of cured films are added to the colorful LED-UV glass coating, these substances are crosslinked through reactions and are instantly cured to form a film under irradiation of an LED-UV lamp, the adhesion to the glass surface is enhanced, the performance of the glass coating is greatly improved, and the formed film has the characteristics of high gloss, high hardness, high adhesion, freezing resistance, boiling resistance, organic solvent resistance, acid-base resistance and salt mist resistance. The preparation method is simple and feasible.
Description
technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a colored LED-UV glass coating and a preparation method thereof. Background technique [0002] LED-UV nano glass coatings are used in glass decoration, glass electrical panels and glass products. After the glass surface is coated with LED-UV coatings, it is both beautiful and can protect the surface of the glass substrate. However, due to the smooth surface of the glass substrate, these will affect the adhesion between the coating film and the glass, which will also affect the adhesion, water boiling resistance, acid and alkali resistance, etc. of the coating film. The LED-UV lamp is used to irradiate and cure, and at the same time, it solves the problems of ozone, energy saving and environmental protection that were generated when the paint was irradiated with a high-pressure ultraviolet mercury lamp. Contents of the invention [0003] Aiming at the deficiencies...
