Problems solved by technology

Most of the commonly used adhesives are synthetic adhesives, such as urea-formaldehyde resin, phenolic resin, etc. These adhesives will release harmful substances such as formaldehyde during use, which will endanger the environment and human health. Therefore, the use of such synthetic adhesives is gradually restricted.

Abstract

The invention discloses a die pressing biosynthesis blockboard and a preparing method thereof. A novel natural composite panel can be obtained. Various physical and chemical performance indexes of finished products meet the national standard and user requirements, pollution is avoided, formaldehyde is low, the formaldehyde releasing amount is smaller than or equal to 0.5 mg / 100 mg, the tensile strength is larger than or equal to 0.8 mpa, the bending strength is larger than or equal to 20 mpa, high-temperature resistance, water resistance, corrosion resistance, ultraviolet ray resistance, ageing resistance, heat resistance and photochemical performance of the novel natural composite panel are all superior to those of an ordinary blockboard, and the novel natural composite panel is a novel panel capable of meeting the modern green and environment-friendliness concept.

Description

technical field [0001] The invention relates to a molded biosynthetic joinery board and a preparation method thereof. Background technique [0002] In recent years, the application of composite boards has become increasingly widespread, and adhesives with different properties are required in the processing and use of composite boards. The commonly used adhesives are mostly artificial synthetic adhesives, such as urea-formaldehyde resin, phenolic resin, etc. These adhesives will release harmful substances such as formaldehyde during use, which is harmful to the environment and human health. Therefore, the use of such synthetic adhesives is gradually restricted. Therefore, there is an urgent need for a new type of adhesive and a new type of board that meets the concept of modern green environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a molded biosynthetic blockboard...
