Abstract

The invention relates to a bathroom wood-based composite material and a preparation method thereof, and belongs to the technical field of decorative materials. White carbon black and a coloring material are soaked with a composite coupling agent, extremely high activity is shown by utilizing the unique three-dimensional silica structure, small particle size and large specific surface area of the nanometer white carbon black, the adsorbing effect on pigment particles is strong, the surfaces of the pigment particles are tightly wrapped, and shielding effect is formed, so that pigment attenuationcaused by ultraviolet irradiation is greatly reduced, sudden light oxygen degradation of a core layer part is delayed, excessive generation of chromophores is blocked, light oxygen degradation of thematerial is slowed down, obvious dark color change is avoided, the color of the composite material is improved, the requirement of bathroom indoor environment is met, and the composite material is harmonious with the indoor integrated environment.

Description

technical field [0001] The invention relates to a wooden composite material for bathroom and a preparation method thereof, belonging to the technical field of decorative materials. Background technique [0002] With the continuous development of the country's economic construction and the improvement of people's living standards, the contradiction between the supply of timber resources and the demand is also becoming more serious. Since the country implemented the natural forest protection project, vigorously building artificial forests has become an important way to solve the contradiction between my country's timber supply and demand. How to rationally and effectively utilize plantation forest resources and develop its huge potential will become a key topic for forestry researchers. Plantation fast-growing wood has the characteristics of wide distribution, strong adaptability, and short growth cycle. It usually becomes a material in about 10 years, so the material is loos...
