Description
Technical Field
The utility model relates to a heat preservation wallboard, especially a multilayer foaming cement takes heat preservation wallboard of surface veneer even.
Background
With the development of the construction industry of China, the heat preservation coefficient of a building is an important assessment index. The existing building also has the requirement, so that the adoption of a heat-insulating mortar layer and even a heat-insulating wallboard aiming at the existing building is an important way for improving the heat-insulating coefficient (energy-saving coefficient) of the existing building, the heat-insulating mortar layer is formed by permeating a large amount of EPS into cement mortar, the material cost is not high, but the construction cost is higher, the design margin is not large particularly during the preparation of a facing plastering, the facing of an outer wall needs to be installed on site, in general, the construction quality of the heat-insulating mortar layer is not easy to control, the adhesive force of cement mudflat is generally lower, and the stripping phenomenon is difficult to avoid. The prior art has considered the advantages of the foamed cement thermal insulation wallboard in application, but the foamed cement thermal insulation wallboard has contradiction in the aspects of heat conductivity and practical application: if the foaming cement heat-insulating wall board with larger aperture and lower density is adopted, the difficulty of directly pasting the wall surface with cement paste is slightly larger, the foaming cement board is generally a through hole, the cement paste consumption is more, the heat conductivity coefficient can be influenced, and the board 2 cm thick originally is not enough. Especially, the foamed cement heat-insulating wall board with larger pore diameter and lower density is easy to be damaged in the aspects of transportation and transportation (the damage rate is more than 25 percent). The foaming cement heat-insulation wallboard is used for improving the heat-insulation coefficient of the existing building in the existing building and has the trouble as above.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a foaming cement composite insulation wallboard, foaming cement insulation wallboard can not have the contradiction in coefficient of heat conductivity and in-service use, can also with wainscot integration, can not satisfy the building energy saving coefficient requirement by the board of 2.5 centimetres thick (the coefficient of heat dissipation of certain difference in temperature, it is significant to air conditioner and cold-proof winter in summer).
The utility model discloses technical scheme: a foamed cement composite heat-insulation wallboard comprises a first foamed cement board and a second foamed cement board, wherein the first foamed cement board and the second foamed cement board are bonded with cement paste through a polypropylene or polyacetylene net, the thickness of each of the first foamed cement board and the second foamed cement board is 10-17 mm, the thickness of the first foamed cement board and the polypropylene or polyacetylene net is 22-36 mm after the first foamed cement board and the second foamed cement board are compounded, the density of the first foamed cement board is 0.9-1.2, and the density of the second foamed cement board is 0.4-0.6 g/ml; the first foamed cement board is used as a substrate and can be directly pasted on a wall surface by cement paste, and the second foamed cement board is arranged on the outer layer.
Further, the utility model discloses the improvement is, second foaming cement board surface subsides have (foaming) PVC veneer, and the PVC veneer can regard as the outer decoration of foaming cement composite insulation wallboard, and the weatherability is good. The outer wall directly pastes through surface treatment (after roughening and whitewashing) when outer wall insulation function is reformed transform the utility model discloses foaming cement composite insulation wallboard then need not spout again and use outer wall coating.
When the first foamed cement board and the second foamed cement board are foamed, polypropylene or polyethylene short fibers (with the length of 2-10 mm and the diameter of about 0.1 mm) are added into the contents and uniformly mixed with cement slurry.
The first foamed cement board (base plate) and the second foamed cement board (panel) are used as composite boards, the density of the base plate is high, the strength can be high when the cement paste is used for lining, and the polypropylene or polyethylene fiber net lining is added, so that the overall strength is high, and the good yield can be ensured during transportation and facing.
Has the advantages that: the utility model provides a foaming cement composite insulation wallboard, foaming cement insulation wallboard can not have the contradiction in coefficient of heat conductivity and in-service use, can also with the wainscot integration, can not satisfy the building energy saving coefficient requirement by the board of 2.5 centimetres thick (the coefficient of heat dissipation of certain difference in temperature, it is significant to air conditioner and winter keep warm summer. The utility model discloses a simplest and conciseness structure has two insulating layers, and basement density is big, and material cost is low, and is rational in infrastructure, and intensity is big, save material, and outer thermal-insulated effectual, light in weight adopts inorganic material long service life basically, and intensity meets the requirements, and the construction is easy. Low cost, difficult damage and being beneficial to large-scale application.
