Abstract

The invention provides a construction method for surface coat of a wooden article. The method comprises the following steps: (1) carrying out surface sanding treatment; (2) carrying out undercoat treatment and UV drying; (3) carrying out coloring and drying; (4) carrying out sanding and dedusting; (5) carrying out middle-layer treatment; and (6) carrying out topcoat treatment, wherein UV wood raw paint in the step (2) contains the following ingredients in parts by weight: 10-15 parts of hexa-functionality polyurethane acrylic resin, 20-25 parts of bi-functionality polyurethane acrylic resin, 30-35 parts of bi-functionality modified UV monomer, 3-5 parts of photosensitizer, 0.1-0.2 part of leveling agent, 0.3-0.5 part of antifoamer, 0.3-0.5 part of humectant, 15-20 parts of nano-silica dispersion solution and 10-15 parts of gas-phase nano-silica matte powder. By the embodiment of the invention, a relatively thin protective layer is obtained on the surface of wood and has excellent waterproof and wear-resisting properties, and meanwhile, the intrinsic grains and texture of the wood are preserved.

Description

technical field [0001] The invention relates to the field of paint surface treatment technology, in particular to a construction method of wood product surface paint, which is mainly used for the construction treatment of wood floor surface paint, and can also be used for the construction treatment of wood product surface paint such as furniture and wooden doors. Background technique [0002] With the improvement of national consumption level and environmental protection requirements, people have more choices and higher requirements when choosing wood products, such as requiring wood products to be closer to the essential color and texture of wood. [0003] Traditional solid wood products, solid wood flooring or solid wood composite flooring have poor weather resistance. When used for a long time in an environment with large humidity and temperature changes, they are prone to deformation and cracking, and their dimensional stability is poor. Especially wooden floors, when us...
