Abstract

The invention discloses resin-impregnated functionalized wood and a processing technology. The formula comprises finished wood, water-soluble low-molecular-weight phenolic resin, a defoaming agent, a formaldehyde eliminating agent, a dispersing agent, a coupling agent, an insect-resist agent and a curing agent. The weight parts of the components are as follows, 82-90 parts of the finished wood, 40-48 parts of the water-soluble low-molecular-weight phenolic resin, 1-3 parts of the defoaming agent, 5-9 parts of the formaldehyde eliminating agent, 2-4 parts of the dispersing agent, 1-3 parts of the coupling agent, 6-10 parts of the insect-resist agent and 1-3 parts of the curing agent. According to the processing technology, redundant gas in wood pores is thoroughly removed through ultrasonic impregnation and vacuum rolling, the impregnation speed of resin is increased, diffusion is uniform, reaction is sufficient, the wood modification time is shortened, the functional improvement effect of the wood is improved, formaldehyde removal treatment is conducted on the resin, the body health of personnel is guaranteed, pollution to the environment is reduced, and the diffusion degree of the resin in the wood pores is ensured.

Description

technical field [0001] The invention relates to the technical field of wood, in particular to resin-impregnated functional wood and its processing technology. Background technique [0002] Wood is a kind of natural renewable porous polymer material. As a kind of green ecological environmental protection material, it has been favored by people all the time, and it is widely used in construction and furniture materials, interior decoration and papermaking, etc. However, under the background of a complete ban on logging in natural forests and a tense contradiction between supply and demand of timber, defects such as flammability, perishability, moisture absorption, insect infestation, deformation, and small diameter of plantation timber largely limit its use. . Therefore, researchers at home and abroad have used various physical, chemical and biological methods to improve the functionality of wood in order to obtain wood-based composites with excellent performance. At present...
