Problems solved by technology

[0007] However, the formaldehyde pollution problem caused by wood-based panels seriously restricts the healthy development and survival of the industry.
In the production of wood-based panels, urea-formaldehyde resin adhesives account for more than 90% of the total. In addition, most enterprises' wood-based panel gluing technology is relatively backward, so that the amount of formaldehyde released from wood-based panels remains high, leading to the deterioration of the living environment.

Abstract

The invention discloses a method for preparing a weather-resistant biological composite. The method includes a coarse vinegar pretreatment procedure and a self-dissolving agent treatment procedure; after the coarse vinegar pretreatment procedure and the self-dissolving agent treatment procedure, pretreated raw materials and a self-dissolving agent are evenly mixed with a mass ratio of m<pretreated raw materials> to m<self-dissolving agent> being 100 to 1-15, and then preparation of the weather-resistant biological composite is completed according to process parameters of paving, pre-pressing, hot-pressing, aging, sanding and edge cutting of conventional fiber boards. The method is easy to realize, convenient to operate and low in production cost.

Description

technical field [0001] The invention relates to a method for preparing a biological composite material, in particular to a method for preparing a weather-resistant biological composite material. Background technique [0002] Activated carbon is a kind of carbon material with well-developed pore structure, large specific surface area and excellent adsorption performance, and has extensive and important uses in various industries. With the development of the national economy, many fields put forward higher requirements for the performance of activated carbon, which further promotes the development of activated carbon in raw materials, production technology and performance. The preparation of activated carbon is a complex process affected and restricted by many factors, and the difference in raw materials and activation treatment processes will have a significant impact on the performance of activated carbon. [0003] The raw materials for preparing activated carbon with excel...
