Abstract
The invention relates to a board and a production technology thereof, in particular to an exterior wall cladding and a production technology thereof. The exterior wall cladding sequentially comprises an extruded sheet layer, a bo-mei board layer and a metallic paint layer from bottom to top. The production technology comprises the following steps: the surface of the bo-mei board is added with a layer of mixture formed by magnesium oxide and putty powder, and the mixture is trowelled; the surface layer of the processed bo-mei board is polished to lead the surface to be level; the surface layer of the polished bo-mei board is coated with a layer of fluorocarbon metal paint; an XPS extruded sheet with the same size as the bo-mei board is processed; the underside of the processed bo-mei board is agglutinated with the processed XPS extruded sheet by epoxide resin. The exterior wall cladding has good heat preservation and insulation performance, is energy-saving and environment-friendly, has level and beautiful surface, and is convenient for construction.
Description
Technical field
The present invention relates to a kind of sheet material and production technology thereof, a kind of specifically exterior wall cladding and production technology thereof.
Background technology
The exterior wall of modern architecture mostly uses decorative floor block to decorate, but along with the development of builing industry, the exterior walls of more and more buildings use exterior wall claddings to substitute decorative floor block, particularly some highrise buildings.Existing exterior wall cladding generally has aluminium alloys exterior wall cladding, plastics link plate, cement calcium silicate board with microporous, cement fibrolite plate etc.Wherein the use at present of aluminium alloys exterior wall cladding is more, but aluminium alloys exterior wall cladding price is higher, and thermal and insulating performance is bad.The plastics link plate is not then prevented fires, easy modification, and the time is long and also aging easily, and application life is shorter, and thermal and insulating performance is bad.Though cement calcium silicate board with microporous and cement fibrolite plate be flexible type not, also can prevent fires, Heavy Weight, fracture, and processing technology complexity easily, surface finish is more difficult.This shows that existing exterior wall cladding all has the shortcoming of himself, can not well satisfy the requirement of modern architecture exterior wall, have much room for improvement.
Summary of the invention
Technical problem to be solved by this invention is: at the shortcoming that above prior art exists, it is good to propose a kind of heat insulation property, environmental protection and energy saving, and surfacing is attractive in appearance, the exterior wall cladding of easy construction and production technology thereof.
The technical scheme that the present invention solves above technical problem is:
A kind of exterior wall cladding is extrusion molding flaggy, glass magnesium flaggy and metal enamelled coating from bottom to up successively.
A kind of production technology of exterior wall cladding may further comprise the steps:
(1) when processing glass magnesium plate, add the compound that one deck is mixed with powder of lacquer putty for use on by magnesia on the surface of glass magnesium plate, and compound is floating, compound and glass magnesium plate are become one;
The top layer of the glass magnesium plate that (2) polishing process step (1) processes makes its surfacing;
(3) at top layer spray one deck fluorine carbon metal paint through the glass magnesium plate after step (2) grinding process;
(4) the processing XPS extruded sheet identical with glass magnesium board size;
(5) epoxy resin bonding is passed through with the XPS extruded sheet that processes through step (4) in the bottom surface of the glass magnesium plate that will process through step (3).
Extrusion molding flaggy and glass magnesium flaggy pass through epoxy resin bonding.The surface of glass magnesium flaggy is provided with the flat surface layer that one deck magnesia mixes with powder of lacquer putty for use on, is sprayed with the metal enamelled coating on the flat surface layer, and the thickness of the flat surface layer that magnesia mixes with powder of lacquer putty for use on is 0.5～1 millimeter.The metal enamelled coating is the fluorine carbon metal paint layer, and moulding flaggy is XPS extrusion molding flaggy.The thickness of extrusion molding flaggy is 20～100 centimetres, and the thickness of glass magnesium flaggy is 6～12 centimetres.
In the step (1), the proportioning of magnesia and powder of lacquer putty for use on is 1: 1～2.
Advantage of the present invention is: because extrusion molding flaggy of the present invention, glass magnesium flaggy and metal enamelled coating are formed, make coefficient of thermal conductivity of the present invention lower, and, thermal and insulating performance.The coefficient of thermal conductivity of national standard sheet material is less than 0.04 in the time of 25 ℃, XPS extruded sheet coefficient of thermal conductivity is in the time of 25 ℃ about 0.03, add glass magnesium plate, after testing, the coefficient of thermal conductivity of exterior wall cladding of the present invention in the time of 25 ℃ less than 0.035, thermal and insulating performance more is better than existing aluminium alloys exterior wall cladding, plastics link plate, cement calcium silicate board with microporous, cement fibrolite plate etc. far above national standard.The present invention has fire prevention, waterproof, anti-ly damages by worms, in light weight, resistance to compression bending resistance, intensity height, advantage such as tongue green for a long time not.Because middle glass magnesium plate is by MgO, mgcl
2Make by hydration reaction Deng inorganic matter, this raw-material formation has just determined its waterproof, anti-performance of damaging by worms.Fireproof performance meets the standard of not firing class material (A level), and has the characteristic of waterproof.The density of glass magnesium plate is 0.9～1.1t/m
3(density of gypsum plank and cement fibrolite plate is: 15t/m
3About) compressive strength is greater than 53Mpa, flexural strength is greater than 80Mpa, does not contain formaldehyde and benzene, compliance with environmental protection requirements.
Because the surface of glass magnesium plate of the present invention adds the compound that one deck is mixed with powder of lacquer putty for use on by magnesia, make the surface finish of glass magnesium plate more convenient, be easier to be polished to desired planeness, make when the surface of glass magnesium plate spray metallic paint, metallic paint more easily forms smooth top layer.And cement calcium silicate board with microporous and cement fibrolite plate etc. need be criticized powder of lacquer putty for use on repeatedly, and polishing just can reach the planeness requirement repeatedly, complex process, and after spraying metallic paint, metallic paint is difficult for forming smooth top layer, and the top layer is easily uneven.Therefore, the present invention can guarantee the smooth of exterior wall cladding surface metal lacquer, makes the exterior wall cladding surface more attractive in appearance.
