Laminated magnesium oxide board

Abstract

The invention relates to the technical field of building boards and particularly relates to a laminated magnesium oxide board. The laminated magnesium oxide board comprises a magnesium oxide board, abalancing layer and a bamboo board. According to the laminated magnesium oxide board, the balancing layer is arranged on an outer layer of the magnesium oxide board, so that moisture in a cement floorcan be effectively prevented from eroding the interior of the magnesium oxide board; the bamboo board serves as a cover of the board and is subjected to carbonization processing treatment, so that the bamboo board can be prevented from bug bite and rotting; and light-burned magnesia, magnesium sulfate heptahydrate, magnesium chloride, styrene-butadiene latex, closed-pore pearlite, kaolin, a couplant, bamboo fibers and a proper volume of pure water serve as production raw materials of the magnesium oxide board, the process is simple, the water resistance and corrosion resistance are improved greatly, and the coefficient of thermal conductivity is relatively low, so that the heat-insulating property of the laminated magnesium oxide board is improved, performance defects of the traditional magnesium oxide boards are made up, the problems of halogenide accumulating and moisture absorption of products are avoided, and thus, the laminated magnesium oxide board is applicable to popularization.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a composite glass magnesium board. Background technique [0002] Magnesium oxychloride material has excellent physical and mechanical properties, and it has outstanding fire resistance and wear resistance, which makes this material widely used in construction engineering, municipal engineering, agricultural production, environmental protection industry, machinery packaging, transportation and light industry.

Problems solved by technology

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, corrosion resistance and low shrinkage. Performance, which is superior to all kinds of artificial boards. However, the glass magnesium boards currently used have problems such as moisture absorption and halogen return, board embrittlement, etc., which affect the quality of the product and limit the wide application of the product, and most of the fabrics use melamine paper, etc. The cover of the material is not environmentally friendly, and the appearance is not natural and beautiful. Therefore, a composite glass magnesium board is proposed to solve the above problems
