Problems solved by technology

[0003] In the material selection of decorative panels, wooden decorative panels are the most used, and the raw materials of wooden decorative panels can be divided into wooden boards and wooden integrated boards. The cost of the overall wooden board is relatively high, so the price is more expensive
The integrated wood board is made of wood powder bonded by glue and molded. Because it contains a lot of glue, although the price is low, it is not environmentally friendly. The glue contains a lot of harmful substances, causing the decorative panel to emit a lot of harmful substances and odors, which is not good for human health.
Moreover, since the integrated wooden decorative panel is made of wood powder, its mechanical properties and workability are poor, and it is easy to drop slag and even crack when performing processing operations such as cutting and nailing
[0004] The Chinese invention patent with the patent application number of 95106184.4 discloses a new Cainiao desktop board and its manufacturing process, using magnesium oxide, magnesium chloride aqueous solution, diatomaceous earth, wood flour, ammonium dihydrogen phosphate and other raw materials, according to a certain ratio, after mixing Stirring, pouring and molding through the mold in turn, after demoulding, the preliminary tabletop board is immersed in water, oxidized and cured at high temperature. The tabletop has the functions of waterproof, fireproof, and crack prevention. , The desktop board made of MDF is not fire-resistant, not water-resistant and has the disadvantages of short service life
[0005] The desktop board of the invention has good fireproof and waterproof properties, but the tabletop board is not environmentally friendly, and contains a large amount of gypsum powder, and the texture is relatively brittle and the strength is low

Abstract

The invention relates to the field of building material preparing, and discloses a method for producing an integrated bamboo wallboard. The method includes the steps of 1, material mixing, wherein polyvinyl chloride resin, calcium powder, a PVC small-tube material, bamboo powder, PE wax, stearic acid AC-1801, a foaming agent, a foaming regulation agent, a calcium-zinc composite stabilizing agent, a toughening agent and dye are placed into a heating mixer to be stirred and then transferred into a cold mixer to be stirred; 2, extrusion molding, wherein the raw materials are transferred into a material barrel of an extrusion molding machine to be heated, enter a flow combining core and then enter a mold to be molded; 3, traction stretching and shaping, wherein a semi-finished product is subjected to traction stretching, and meanwhile vacuumizing shaping is carried out; 4, cutting and high-temperature laminating, wherein a board is cut and finally subjected to high-temperature laminating, and the finished integrated bamboo wallboard is produced. The integrated bamboo wallboard produced with the method is environmentally friendly, high in strength, stable in physical and chemical performance and capable of adsorbing static electricity, and later-period installation and processing of the board are convenient.
