Description
The present invention relates to a kind of building board and manufacture craft thereof as building non-bearing wall body or building roofing.
Along with the continuous progress of society, more and more higher to the requirement of building and building masonry wall material.As the modern building materials for wall, not only require it to possess certain intensity, and require it to have the performance of good sound insulation, thermal insulation, damp proof insulation and fire prevention, waterproof, etch-proof performance.Building masonry wall has the branch of bearing wall and non-bearing wall body, and materials for wall also has the branch of bearing wall material and non-lbearing wall material, for non-lbearing wall material, except the general requirements of above-mentioned materials for wall, also must possess the characteristics of light weight.Non-lbearing wall material kind of the prior art is a lot, has both comprised the sheet material as single levels such as gypsum hollow lath and cement perlite light thermal-insulation sheet materials, also has such as composite materials such as color steel sheet sandwich sheet and concrete built-in insulation layer combined walls.Though the material of these single levels and composite material respectively have its advantage and strong point, also all exist some significantly not enough.For example, gypsum hollow lath is heavier, and sound insulation, damp proof insulation performance are also relatively poor, only is suitable for using under the dry environment, and it is relatively poor to add its intensity, so can only be unsuitable for as building roofing as materials for wall in the building non-bearing.The water absorption rate of cement perlite partition board is quite big, and also must carry out secondary operations during as inner wall of building body material and handle its surface, so the construction technology more complicated.Color steel sheet sandwich sheet not only raw material is more expensive, and steel plate is also as easy as rolling off a log by corrosion, therefore must often carry out anti-corrosion treatment.The construction technology of concrete built-in insulation layer combined wall is more complicated, also can't be used for building roofing.In a word, the scope of application limitation of various non-lbearing wall materials of the prior art is bigger, the construction technology more complicated that has.
Purpose of the present invention promptly is to obtain a kind of light weight, and manufacture craft and construction technology are easy, not only can be used as the building non-bearing wall body but also can be used as the building board of building roofing.
To achieve these goals, the present invention adopts the method for mould composite molding, presss from both sides with lightweight thermal insulation layer between two-layer panel, thereby obtains a kind of lightweight composite building board.Panel is composited by panel material and glass fabric, and panel material is mainly formulated by proper proportion by magnesia and inorganic magnesium salt, and lightweight thermal insulation layer is aggregate with the foamed polystyrene then, is that cementitious material is formulated with the panel material.The manufacture craft of sheet material mainly comprises preparation slip, moulding, curing in the mold and demoulding maintenance 4 procedures, technology is fairly simple, the composite building board that is obtained has sound insulation preferably, heat preservation and insulation and waterproof, Corrosion Protection, and light weight, surfacing, intensity height can directly be used as building non-bearing external and internal wall material and building roofing plate.Be described in further detail below in conjunction with the technical characterictic of specific embodiment lightweight composite building board of the present invention.
