Composite building material plate for buildings

Abstract

The invention relates to the technical field of building plates, particularly to a composite building material plate for buildings. The composite building material plate comprises a base material plate, a waterproof layer and a bamboo surface plate. According to invention, the waterproof layer is arranged on the outer layer of the base material plate, so that water and moisture in a cement floor can be effectively prevented from corroding the interior of the plate; a bamboo surface plate is used as a plate cover, and is subjected to carbonization processing treatment, so that the bamboo surface plate can be prevented from being eaten and rotted by insects; and light calcined magnesia, magnesium sulfate heptahydrate, magnesium chloride, styrene-butadiene latex, closed-cell perlite, kaolin,a coupling agent, bamboo fibers and a proper amount of pure water are used as manufacturing raw materials of the building material plate, so that the process is simple, the water resistance and corrosion resistance are greatly improved, the heat conductivity coefficient is low, the heat preservation performance is improved, the performance defects of a traditional building material plate are overcome, the problems of product halogenation and moisture absorption are avoided, and the method is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of building panels, in particular to a composite building material panel for construction. 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. Applications. After the existing building material board is added with magnesium oxychloride, it has outstanding fireproof performance, 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. It is better than the comprehensive performance of all kinds of man-made panels. However, the currently used building mat...

AI Technical Summary

Problems solved by technology

After the existing building material board is added with magnesium oxychloride, it has outstanding fireproof performance, 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. It is better than the comprehensive performance of all kinds of man-made panels. However, the currently used building material panels have problems such as moisture absorption and brine return, and the embrittlement of the panels, which affects the quality of the product and limits the wide application of the product. Most of the fabrics are covered with melamine paper and other materials, which is not enough. Environmental protection, losing the appearance is not natural and beautiful enough, therefore, a composite building material board for construction is proposed to solve the above problems
