Fiber polymerized concrete external wall panel

Abstract

The invention relates to a fiber polymerized concrete external wall panel. The fiber polymerized concrete external wall panel comprises a concrete layer on the surface and a heat-insulating material layer on the bottom surface, wherein a fiber material layer is arranged in the concrete layer, the fiber material layer and concrete bond and solidify through an adhesive, the concrete layer and the heat-insulating material layer bond and solidify through an adhesive, and a coloring layer is arranged on the upper surface of the concrete layer. According to the invention, cement is replaced by resin adhesives, gravel and other materials are mixed and bond through reinforcing fibers, and the strength is improved; anti-ultraviolet corrosion-resistant resin and color powder are adopted by the coloring layer on the upper surface of the concrete layer, compared with natural granite, the coloring layer has a brighter color, and cannot fade, the surface resists wear, and is sealed and waterproof, and the phenomenon that an external wall panel cracks or delaminates and falls off due to the fact that seeping water is frozen cannot happen; the heat-insulating material layer on the bottom surface is light in weight and improves the heat insulation effect. Compared with similar cement concrete panels, the fiber polymerized concrete external wall panel has the advantages that the strength is improved by about four times, the weight is reduced by above 15%, the appearance is attractive, and the fiber polymerized concrete external wall panel is firm and durable.

Description

technical field [0001] The present invention relates to building boards, especially a concrete exterior wall board containing fiber reinforced material, coagulated and polymerized by binder. Background technique [0002] At present, the exterior wall panels used in existing buildings generally include stone and concrete panels. Stone exterior wall panels are usually cut and polished from mined natural stone. Concrete panels are made by using cement as a binder to bond sand and gravel. , and solidify and shape through the mold. The above-mentioned stone and concrete slabs are heavy, high-strength, and have flame-retardant properties. However, due to the large number of micropores inside the materials, the water absorption is relatively high. It is the internal micro-pores that freeze in winter, which can easily cause cracking or peeling off of the exterior wall panels. Contents of the invention [0003] In view of the above deficiencies of the existing building exterior w...
