Abstract

The invention belongs to the technical field of composite materials, and particularly discloses a sand-wood composite material and a preparation method thereof. Phenolic resin, polystyrene, attapulgite, a coupling agent, titanium dioxide, silica sand and the like are matched in a specific proportion for use for the first time, the coupling agent can improve the dispersity of titanium dioxide and silica sand in a system, titanium dioxide and silica sand are prevented from being gathered into a cluster in the system, and the heat preservation performance of the product is improved; meanwhile, the coupling agent can firmly couple titanium dioxide and silica sand into a base material formed by phenolic resin, polystyrene and the like, so that the product is stable in structure and has lastingheat preservation performance; titanium dioxide and the coupling agent are coupled and uniformly dispersed in the whole system, so that the product has waterproof performance, the water absorption phenomenon of the product after long-time use is avoided, the water content of the product is reduced, and the heat preservation durability of the product is improved; and glass fibers can maintain the pore structure of the product, the bonding compactness among all raw materials is improved, and the heat preservation performance of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a sand-wood composite material and a preparation method thereof. Background technique [0002] Building materials are a general term for materials used in civil engineering and construction engineering. It can be divided into structural materials, decorative materials and some special materials. Common building materials include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics and composite materials. With the improvement of people's living standards, the requirements for the living environment have also been continuously improved. They all hope that their houses can be as warm as spring in the severe winter and have a good heat preservation effect; the materials used in the kitchen can prevent oil and dirt, etc. Building materials, such as oil-proof materials and insulation materials. [0003] In the prior art,...
