Abstract

The invention discloses a preparation method of resin-reinforced wood and belongs to the technical field of building materials. Through hydrothermal and high-pressure blasting treatment, the ultrastructure of wood is destroyed and it changes from a firm fibrous structure into a loose hollow porous structure. Through ultra-fine treatment of particles, degree of crystallization is reduced, which facilitates impregnation with Japan wax silicone oil. Finally, a rubber compound and reinforced fibers are mixed and injected into a vacuum extruder, and the mixture is extruded into a mould loaded withpretreated wood. After cooling and demoulding, the resin-reinforced wood is obtained. The resin used in the invention is polyfluororesin with lubricity. Thereby, abrasion loss of a resin layer on thewood surface is low; after the wood undergoes pressure impregnation with the Japan wax silicone oil, silicon dioxide introduced into pores of the wood also has an effect of enhancing the internal structure of the wood itself. The product has a wide application prospect.

Description

technical field [0001] The invention discloses a method for preparing resin-reinforced wood, which belongs to the technical field of building materials. Background technique [0002] As the only renewable natural material among the four major building materials in the world today, wood not only has a high strength-to-weight ratio, outstanding heat insulation, sound absorption and sound insulation, earthquake resistance, natural beauty, and comfortable texture and other environmental coordination properties , and has the advantages of low processing energy consumption, environmental protection, natural degradation and recycling. Therefore, as people pay more and more attention to energy conservation, environmental protection and sustainable development, people's demand for wood is also constantly growing. At present, the protection of the environment and forest resources in various countries makes the high-quality wood used in engineering relatively scarce, prompting countri...
