Abstract

The invention discloses a preparation method of a high-strength environment-friendly plate, and relates to the field of environment-friendly materials. The preparation method comprises the following steps of crushing and mixing of wood materials, stewing and hot grinding of the wood materials, preparation of wood fibers, mixing of the wood fibers and an adhesive, pavement, pre-pressing and hot pressing of the materials, sanding treatment and roller coating of a waterproof coating. According to the method, waste wood and Chinese herbal medicine additives are mixed, stewed and ground, the prepared wood materials have the good antibacterial property, corrosion resistance and moth repellency, wood material shell powder is mixed with the adhesive for bonding, the plate prepared through pressinghas good hardness and strength, the raw material source is wide, and the production cost is low.

Description

technical field [0001] The invention relates to the field of environment-friendly materials, in particular to a method for preparing a novel high-strength environment-friendly plate. Background technique [0002] my country is a country with an unbalanced forest structure and a lack of resources. The contradiction between supply and demand of timber resources has become increasingly prominent. The shortage of raw material supply has become a bottleneck restricting the development of the wood-based panel industry. However, the pressure of raw material shortage has also accelerated the adjustment of wood supply channels for the man-made industry. , to speed up the recycling of waste wood material resources. The recycling of waste wood can not only realize the use of waste wood materials as raw materials for the wood-based panel industry, to a certain extent relieve the pressure of insufficient supply of wood resources, but also change the traditional unidirectional wood consump...
