Magnesium oxysulfate pasting wood rock porcelain non-combustible board and manufacturing method thereof

Abstract

The invention belongs to the field of building decorative boards, and particularly relates to a magnesium oxysulfate pasting wood rock porcelain non-combustible board and a manufacturing method thereof. The raw materials and percentages of the board are as follows: 40% of magnesium oxysulfate; 12% of magnesium oxide; 3.5% of alumina; 3% of an electro-conductive porcelain powder; 3% of an electro-conductive mica powder; 3% of lithopone; 5% of perlite; 15% of a 100-200 mesh wood powder; 5% of a glass fiber cloth; 3% of a balance cloth; 3% of wood veneer; 2% of a waterborne white latex; 2% of a waterborne UV; and 0.5% of a waterborne UV color concentrate. The steps of the manufacturing method are as follows: 1) preparing a magnesium oxysulfate substrate with a fine pore structure; 2) laying the balance cloth and the wood veneer on two sides of the magnesium oxysulfate substrate, and performing hot pressing; 3) performing cold pressing shaping; and 4) performing double sided sanding treatment, and roll coating a waterborne UV color concentrate primer, a waterborne UV primer and a topcoat. The board has light texture, high surface brightness and high hardness, has good fireproof, moisture proof and temperature difference resistant performances, does not contain asbestos, formaldehyde and harmful radioactive elements, is smoke-free, non-toxic, odor-free in fire, has strong water resistance and no moisture-absorption and halogen-returning property, and has good heat preservation effects and wide application range.

Description

technical field [0001] The invention belongs to the field of building decoration boards, in particular to a magnesium oxysulfide laminated wood rock porcelain non-combustible board and a manufacturing method thereof. Background technique [0002] At present, the commonly used building decoration boards are: blockboard, plywood, particle board, density board, cement fiberboard, gypsum board, PVC board, wood-plastic board, aluminum-plastic board, aluminum foil board, aluminum gusset board, etc. The above-mentioned boards have their own advantages and disadvantages, and their scope of application is small. For example, blockboard, plywood, particle board, and density board have poor fire resistance and high formaldehyde content. They burn quickly after encountering a fire source and emit a large amount of toxic smoke. It is difficult to extinguish in time; cement fiberboard and gypsum board are heavy, and have poor waterproof and moisture-proof effects; wood-plastic board is br...

Problems solved by technology

The above-mentioned boards have their own advantages and disadvantages, and their scope of application is small. For example, blockboard, plywood, particle board, and density board have poor fire resistance and high formaldehyde content. They burn quickly after encountering a fire source and emit a large amount of toxic smoke. It is difficult to extinguish it in time; cement fiberboard and gypsum board are heavy, and have poor waterproof and moisture-proof effects; wood-plastic board is brittle, not tough enough, and the impact resistance is not strong; aluminum foil board and aluminum gusset board are expensive.

In order to solve the defect of the small application range of traditional architectural decorative panels, in recent years, technicians in the field have developed architectural magnesite decorative panels, also known as glass magnesium boards and magnesite boards, which have wide application ranges, strong adaptability, and fire resistance. Excellent, durable, insect-proof, mildew-proof, heat-insulating and energy-saving, but it also has the defects of low mechanical strength, easy to absorb moisture and return to halogen, strong corrosion of chloride ions to metal, and poor stability
