Problems solved by technology

Traditional plywood decoration materials will release a large amount of formaldehyde and other carcinogens during use. After the solid wood board is impregnated with preservatives, painted and other processes, on the one hand, there are many health and safety hazards during use. On the other hand, wood It is a non-renewable resource, a large amount of deforestation leads to the deterioration of the natural environment, and the cost is also increasing year by year
[0003] More importantly, the traditional plywood and solid wood boards generally have the disadvantage of high hygroscopicity, which further leads to the easy breeding of microorganisms, and the formation of pathogenic microorganisms such as fungi (bacteria) and mold on the surface of the material. endanger the health of children and parents

Description

technical field [0001] The invention relates to the field of materials, in particular to a herbal wood-plastic composite material and a preparation method thereof. Background technique [0002] With the development of the home improvement market, residents' awareness of environmental protection is getting stronger and stronger, and the requirements for interior decoration are getting higher and higher. Traditional plywood decoration materials will release a large amount of formaldehyde and other carcinogens during use. After the solid wood board is impregnated with preservatives, painted and other processes, on the one hand, there are many health and safety hazards during use. On the other hand, wood Belonging to non-renewable resources, a large number of deforestation has led to the deterioration of the natural environment, and the cost has also increased year by year. [0003] More importantly, the traditional plywood and solid wood boards generally have the disadvantage ...
