Environment-friendly multifunctional composite artificial board

Abstract

The invention discloses an environment-friendly multifunctional composite artificial board. The artificial board comprises a surface layer, a middle layer and a bottom layer. The surface layer and the middle layer are bonded together through an adhesive layer, and the middle layer and the bottom layer are bonded together through an adhesive layer. The upper surface of the surface layer and the lower surface of the bottom layer are each coated with a functional protection coating. The adhesive layers are formed by inorganic phosphate adhesives which comprise the raw constituents of sodium phosphate, titanium dioxide powder, nano-silica, spinel particles, tourmaline powder, magnesium oxide and zinc oxide. The artificial board has the advantages that the structure is simple, and design is reasonable; the inorganic phosphate adhesives are adopted for both manufacturing of the board and bonding of the board layers, so that the problems that an artificial board generates poisonous and harmful gas and pollutes the environment are solved fundamentally; the artificial board has water resistance, flame resistance, antibacterial properties, worm damage resistance and the like; the artificial board is good in durability and use safety and long in service life.

Description

technical field [0001] The invention relates to the field of wood-based panels, in particular to an environment-friendly multifunctional composite wood-based panel. Background technique [0002] Wood-based panels are made of wood or other non-wood plants, processed into component materials of various shapes such as veneers, shavings or fibers, and recombined with (or without) adhesives and other additives. . Most of the existing wood-based panels in the market are products with adhesives applied, and the adhesives are usually aldehyde organic adhesives, which can continuously release toxic gases such as formaldehyde, benzene, and ammonia into the environment, seriously polluting the environment and affecting people. of good health. At present, the environment-friendly wood-based panels developed and used in the industry usually adopt the method of adding anion coating to suppress the release of toxic gases in the wood-based panels. The defect of gas, and the limitations o...

Problems solved by technology

Most of the existing wood-based panels in the market are products with adhesives applied, and the adhesives are usually aldehyde organic adhesives, which can continuously release toxic gases such as formaldehyde, benzene, and ammonia into the environment, seriously polluting the environment and affecting people. good health

At present, the environment-friendly wood-based panels developed and used in the industry usually adopt the method of adding anion coating to suppress the release of toxic gases in the wood-based panels. Gas defects, and the limitations of the existence time, contact area, and validity period of toxic gases fixed by negative ions cannot fundamentally solve the above-mentioned problem of wood-based panels polluting the environment

In addition, the existing wood-based panels have single functions, poor durability and durability, and short service life
