Magnesium oxysulfate melamine paper decoration surface inorganic rock porcelain non-combustible board and production method thereof

Abstract

The invention particularly relates to a magnesium oxysulfate melamine paper decoration surface inorganic rock porcelain non-combustible board and a production method thereof, wherein the raw materialscomprise: 40% of magnesium oxysulfate, 12% of magnesium oxide, 5% of alumina, 5% of a glass fiber cloth, 4% of perlite, 3% of electric-conduction procelain clay powder, 3% of electric-conduction micapowder, 4% of lithopone, 11% of 100-200 mesh wood powder, 4% of tourmaline powder, 3% of a balance cloth immersed with a melamine glue, 3% of decoration paper immersed with a melamine glue, and 3% ofwear-resistant paper immersed with a melamine glue. The production method comprises: 1) preparing a magnesium oxysulfate substrate having a fine pore structure; 2) respectively spreading both surfaces of the magnesium oxysulfate substrate with a balance cloth immersed with a melamine glue, decoration paper immersed with a melamine glue, and wear-resistant paper immersed with a melamine glue; and3) carrying out hot pressing molding. According to the present invention, the magnesium oxysulfate melamine paper decoration surface inorganic rock porcelain non-combustible board has advantages of light weight, smooth surface, high hardness, good fireproof performance, good moisture proof performance, good temperature-difference resistance, strong water resistance, no moisture absorption halogenaccumulation, good thermal insulation effect and wide application range, and does not contain asbestos, formaldehyde and harmful radioactive elements.

Description

technical field [0001] The invention belongs to the field of building decoration boards, in particular to a magnesium oxysulfide melamine paper-faced inorganic 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-pla...

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
