Abstract

The invention discloses a wood composite material and a preparation method thereof. The preparation method comprises the steps that hot water extraction treatment is conducted on a wood veneer first,the extraction temperature is 30 DEG C-70 DEG C, the extraction time is 25-35 min, and the treated wood veneer is placed into 0.2 mol / l-0.4 mol / l of calcium chloride solution for magnetic stirring, then 0.25g / L-0.5g / L of a coupling agent is added for dipping under the ambient temperature and the normal pressure; then the wood veneer is placed into the sodium carbonate solution for dipping under the normal pressure condition; then the wood veneer is placed into 20%-40% of polyethylene glycol solution and 15%-25% of epoxy resin solution for dipping under the normal pressure condition; and the wood veneer is subjected to boiled desalting treatment and then dried. According to the wood composite material prepared through the preparation method, the weight increase rate is increased remarkably,and the abrasion resistance is increased obviously.

Description

technical field

[0001] The invention relates to the technical field of wood composite materials, in particular to a wood composite material and a preparation method thereof. Background technique

[0002] Wood is one of the most typical biomass materials in nature, widely used in construction, decoration and furniture manufacturing and other fields. my country's current non-renewable resources are increasingly depleted, and high-quality wood resources are seriously scarce. However, most types of raw wood have limited application fields due to their structural characteristics, poor water resistance and abrasion resistance, and low strength and hardness. Those skilled in the art have found through research that the modification of raw wood can effectively improve the relevant mechanical properties of raw wood. Among them, the wood composite board modified by calcium carbonate can improve its strength, density, hardness and wear resistance. promoted. Effective calcium carbonat...
