Abstract

The invention discloses solvent-free LED cold light source curing UV coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 40 parts of polyurethane acrylic resin, 6 parts of a cracking type initiator, 0.5 part of polyether-polysiloxane and 51.5 parts of active monomers. The preparation method of the solvent-free LED cold light source curing UV coating comprises the following steps: stirring the cracking type initiator, a hydrogen abstracting type photoinitiator and the active monomers according to a preset ratio until the mixture is dissolved completely; then adding the polyurethane acrylic resin and the polyether-polysiloxane, and fully stirring uniformly to obtain the final product. The solvent-free LED cold light source curing UV coating has the beneficial effects that under the premise that a coating layer is not affected, the problems of odor and pollution are solved, energy is saved, the production efficiency is improved, the odor is small, power consumption is low, production efficiency for consumers can be improved, and the production costs are saved.

Description

technical field [0001] The invention relates to a coating, in particular to a solvent-free LED cold light source curing UV coating and a preparation method thereof. Background technique [0002] UV light-curing coating is a functional coating that uses polyurethane acrylic resin and initiator as the main film-forming substance, active monomers, additives, and solvents to assist the film-forming substance through a high-pressure mercury lamp. It is currently in urgent need of LED cold light sources on the market. Solvent-free UV coating. [0003] The existing UV light-curing coatings available in the market are sprayed on products (such as: mobile phone casings, notebook casings, home appliances, cosmetic casings, etc.), and after being cured by ultraviolet high-pressure mercury lamps, the coating film will turn white if the solvent does not evaporate. Or the phenomenon of paint falling off, which volatilizes into the air and has a strong smell and pollution, and its high-pr...
