Abstract

The invention discloses an LED-UV ultraviolet light curing wood nano-coating and a preparation method thereof, which is composed of the following raw materials in weight percent: 25-30% of polyurethane acrylate crosslinked with pentaerythritol triacrylate and polyisocyanate, Fatty acid modified polyester acrylate resin 10‑15%, ethoxylated modified trimethylolpropane triacrylate 20‑25%, dipropylene glycol diacrylate 10‑20%, wetting and dispersing agent 0.2-1.0%, nano-barium sulfate powder is 10-15%, UV UV curable monomer dispersion of nano wear-resistant particles is 2-5%, hydrogen abstraction type photoinitiator is 2-4%, active amine is 1‑3%, cracking photoinitiator is 2‑4%, leveling agent is 0.2‑0.5%, defoamer is 0.2‑0.5%, and polymerization inhibitor is 0.1‑0.3%. The UV-curable coating of the present invention only needs 50-60mj / cm2 of LED-UV ultraviolet light energy to reach the required curing degree, which greatly reduces the energy required for coating curing, improves construction efficiency, and reduces wood surface coating. The possibility of quality defects in fabric construction.

Description

technical field [0001] The content of the present invention relates to the field of LED-UV ultraviolet light curing materials, in particular to the technology of LED-UV ultraviolet light curing wood coatings, and in particular to an LED-UV ultraviolet light curing wood nano coating and a preparation method thereof. Background technique [0002] Traditional wood coatings mainly include solvent-based PU polyurethane coatings, solvent-based PE polyester coatings, and solvent-based NC nitro coatings. With the continuous innovation of coating industry technology, following the above-mentioned traditional solvent-based coatings, mercury lamp-type UV-curable coatings and water-based coatings have been developed, especially mercury-lamp-type UV-curable coatings, which are more and more widely used. Mercury lamp-type UV coatings have significant characteristics such as high solid content, fast curing, low emission, less pollution, assembly line production, and excellent paint film pe...
