Problems solved by technology

[0002] At present, the domestic lightweight wall panels are mainly lightweight aggregate concrete or foamed concrete structures, which have the problem of insufficient thermal insulation performance. At present, the domestic steel structure roof panels are generally made of color steel plates with insulation layers, which generally have a high water absorption rate. The problem is that the thermal insulation wall panels and steel structure roof panels need to be coated with a layer of waterproof coating after installation to improve waterproof performance. However, in some places with long rainy seasons, waterproof and anti-seepage of wall panels and roof panels are required Performance has stricter requirements

Abstract

The invention discloses an RPC light insulation board, which comprises an RPC layer with a cavity and an insulation layer arranged in the cavity, wherein the RPC layer comprises the following raw material components: 80-120 parts of cement, 16-22 parts of mineral powder, 20-27 parts of silica fume, 138-146 parts of quartz sand, 47-56 parts of quartz powder, 16-25 parts of fibers, 21-30 parts of water and 2.5-3.6 parts of a water reducing agent. According to the invention, the RPC layer is adopted to wrap the heat insulation layer, so that the waterproof and durable performances of the whole wallboard and roof board can meet the requirements; the heat insulation layer is integrally wrapped by the RPC layer, so that no moisture exists in the heat insulation layer, no external moisture entersthe heat insualtion layer, and the heat insulation performance of the heat insulation layer can be continuously not reduced; the reinforcing plates are used for supporting, so that the overall strength of the structure is guaranteed; and by utilizing the ultrahigh strength and bending resistance of the RPC layer, the RPC layer can achieve enough strength and bending resistance under the conditionthat the RPC layer is thin.
