Multipurpose glass fibre and magnesium eco-plate and preparation method thereof

Abstract

The invention discloses a multipurpose glass fibre and magnesium eco-plate which is characterized by being prepared from the following raw materials, by weight, 42-45 parts of light calcined magnesia, 40-42 parts of magnesium chloride hexahydrate, 6-7 parts of tourmalinite powder, 0.2-0.25 part of a silane coupling agent kh550, 1.5-2 parts of waterborne polyurethane, 6-8 parts of 5% polyvinyl alcohol solution, 2-3 parts of spent pulping liquor, 7-9 parts of waste glass powder, 4.5-5 parts of metakaolin, 2.5-3 parts of aluminium dihydrogen phosphate, 0.8-1 part of aluminum sulfate, 1-2 parts of vinyltriethoxysilane, 15-18 parts of thermoplastic phenolic resin, 5-6 parts of 25% urotropine aqueous solution, 1.5-2.5 parts of aluminium silicate fibre and a proper amount of pure water. According to the invention, insufficiencies of materials such as artificial marble, ceramic tile, natural stone and the like are overcome. The multipurpose glass fibre and magnesium eco-plate has high heat-resistant and fireproofing grade, is nontoxic, harmless, waterproof and fracture resistant, has high strength and can be applied to interior and exterior walls, decorative sheets, furniture, floor and the like.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a multipurpose glass magnesium ecological board and a preparation method thereof. Background technique [0002] Magnesium oxychloride gel material is an air-condensing material, which has the energy-saving function of producing products without burning and steaming. Magnesium oxychloride material has excellent physical and mechanical properties, and it has outstanding fire resistance and wear resistance, making it This material is widely used in construction engineering, municipal engineering, agricultural production, environmental protection industry, machinery packaging, transportation and light industry. Glass magnesium board is the leading product in the magnesium oxychloride gel material industry. It has outstanding fire resistance, and the fire resistance limit can reach 1-4 hours. It has excellent bending resistance, impact resistance, heat insulation, heat preservation...

AI Technical Summary

Problems solved by technology

[0003] Poor water resistance is a defect that hinders the development of glass magnesium board. Due to the structural characteristics of hydration products, the board is easy to return to halogen, warp and deform when used in a humid environment, which limits the scope of use and service life of glass magnesium board.
