Abstract

The invention discloses a wood-plastic composite material for an indoor suspended ceiling. The wood-plastic composite material is prepared from the following raw materials: high-density polyethylene,plant straws, wood flour, surface-modified glass fibers, rare earth phenolic resin, nano calcium carbonate, illite, kaolin, a compatilizer and a lubricant. The surface-modified glass fibers are prepared according to the following process: uniformly mixing glass fibers with hydrogen peroxide, reacting at 95-100 DEG C, and filtering and drying to obtain a material A; uniformly mixing with isocyanatopropyltriethoxysilane and ethanol, reacting at 72-78 DEG C, filtering and drying to obtain a material B; uniformly mixing with 1H, 1H, 10H, 10H-perfluoro-1, 10-decanediol and 1, 4-dioxane, adding dibutyltin dilaurate, uniformly stirring, heating to 40-45 DEG C under the protection of nitrogen, reacting, adding diethylenetriamine for reaction, filtering, washing and drying to obtain a material C; and carrying out low-temperature plasma treatment on the material C, immersing the material C into a rare earth solution, standing, filtering, washing and drying.

Description

technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to a wood-plastic composite material for indoor ceilings. Background technique [0002] Wood-plastic materials are made of thermoplastics such as polyethylene, polypropylene, polyvinyl chloride, and polystyrene, and wood powder such as wood powder, plant straw powder, and plant seed shells, and are made by extrusion, injection molding, and compression molding. Compared with wood materials, it has the advantages of not easy to deform and crack, prevent moth and mildew, high mechanical performance, light weight, moisture-proof, acid and alkali resistance, corrosion resistance, etc. It is an ideal composite material. A substitute for wood and plastic, it has been widely used as a ceiling material for home decoration. With the development of the economy and the improvement of people's living standards, people's requirements for the quality of life and living environment ...
