Problems solved by technology

[0002] Poplar has the advantages of light weight, high strength, good elasticity, long fiber and high content, and easy processing, so it has a wide range of uses. Many countries in the world have listed poplar as an important industrial raw material; poplar has poor aging resistance However, outdoor products such as outdoor wooden flooring and wooden exterior wall decoration materials are more and more favored by consumers. When used outdoors, a series of environmental factors will aggravate the aging of wood, making the wood prone to yellowing, gloss loss, The roughness increases, which greatly affects its performance and reduces its service life; therefore, a method to enhance the aging performance of poplar should be invented

Abstract

The invention belongs to the technical field of wood treatment, in particular to a coating method for improving aging resistance of a poplar board. The coating method comprises the following specific steps: (1) the processed poplar board is dipped in calcium chloride solution for dipping, and is taken out to dip in ethanol solution; (2) the poplar board is processed by steam, and is taken out for hot pressing and drying; and (3) the poplar board is dipped in paint, and is taken out for microwave drying; and the paint is prepared by the following raw materials: tin powder, salicylaldehyde, polyvinyl chloride resins, petroleum resins, tertiary butanol, algal polysaccharides, acrylic emulsion, tetraethoxysilane and water. The coating method effectively improves corrosion resistance and worm damage resistance of the poplar board, improves the color thickness of the poplar board, greatly improves the surface strength and wear resistance of the poplar board, improves fire resistance and flame retardance of the poplar board, prolongs the service life of the poplar board, and improves the use performance.
