Abstract

The invention relates to the technical field of coatings, and provides a photocuring matte clean-surface wood coating. The invention provides a light-cured matte surface-cleaning wood coating. The light-cured matte surface-cleaning wood coating is prepared from 25-35 parts of acrylic resin, 7-13 parts of a photoinitiator, 15-20 parts of matte powder, 3-8 parts of glass powder, 0.5-3 parts of a dispersing agent, 15-25 parts of a reactive diluent, 0.1-1 part of an anti-sagging auxiliary agent and 0.4-1.8 parts of an auxiliary agent. Acrylic resin is used as a main component, contains carboxyl groups with higher reaction activity, can be compounded with a photoinitiator for use, can be quickly polymerized, cross-linked and cured within a very short time under the irradiation of LED (Light Emitting Diode) light, and is mixed with glass powder, matt powder, a dispersing agent, a reactive diluent, an anti-sagging auxiliary agent and an auxiliary agent at the same time; after a paint film is formed, the interlayer adhesive force is good, the covering power is high, the hardness is high, the scratch resistance is good, and the requirement that the Martindeer is smaller than or equal to the first grade can be met.

Description

technical field [0001] The application belongs to the technical field of coatings, in particular to a light-cured matte clear wood coating and a preparation method thereof. Background technique [0002] LED curing coating refers to the use of photosensitivity of photoinitiator (photosensitizer) to initiate a reaction under the irradiation of LED light, form excited ecological molecules, decompose into free radicals or ions, and polymerize, graft, and crosslink unsaturated organic compounds. Wait for chemical reactions to achieve the purpose of curing coatings. [0003] LED light-curing coating is a kind of high-efficiency, environmental protection, energy-saving, high-quality light-curing coating, which fully complies with the "4E" principle. Generally, LED curing energy consumption is 1 / 5 of thermal curing, and LED curing coatings contain less volatile components, less pollution, can reduce raw material consumption, and help reduce economic costs, and the coating film of L...
