Abstract
The utility model discloses a kind of weathering steel thermal insulating composite panel, comprise the sheet material of two pieces of end bendings, described board selection weathering steel, fill insulant material between described sheet material, sealed by weather strip between the bending part at described sheet material two ends, described sheet material comprises panel and backboard, described panel selects thickness to be the weathering steel of 1.2mm or 2.0mm, described backboard selects thickness to be the zinc-plated weathering steel of 1.2mm, polyurethane heat insulation material selected by described heat insulating material, and PVC weather strip selected by described weather strip.The weathering steel thermal insulating composite panel that the utility model provides, it has energy-saving and environmental protection, economical and practical advantage, uses middle color even, does not play slag, do not come off.
Description
Technical field
The utility model relates to a kind of constructional materials, is specifically related to a kind of weathering steel thermal insulating composite panel.
Background technology
In prior art, weathering steel sheet material mainly contains following several.
1, weathering steel lamina is used, surface imitative rust paint or imitative rust powder spray make autoxidation rust red effect, be characterized in that color is even, color is single, corresponding shortcoming shows because be lamina, there is no energy-saving heat preserving function, can not secondary oxidation when doing outdoor decoration plate, the color change of weathering steel in natural environment cannot be realized, because the imitative rust paint that surface is done or imitative rust powder spray form stable enamelled coating on surface, intercept the oxidation again of weathering steel composition.
2, weathering steel lamina surface acid solution or alkali lye or with watering in weathering steel surface direct oxidation, produces corrosion, is directly used in outdoor decoration or landscape ornamental after there is rust.The feature of this sheet material produces the own rust of weathering steel fast, its shortcoming weathering steel sheet metal thickness is very thick, prevent rust from wearing, the aggressive chemistry composition on weathering steel surface does not neutralize simultaneously, strong chemical reaction can accelerate the continued oxidation of weathering steel, and As time goes on, surface can produce anvil cinder and peel off, and continued oxidation peels off, until rust is logical.General designer, usually to increase the risk that thickness overcomes continuous corrosion, uses in the majority with the weather-resistant steel plate that 8mm to 20mm is thick.
3, chemical treatment is done on the surface of weathering steel, produces corrosion rust rear surface and makees layer of transparent varnish again, intercept the oxidation of air.The feature of this sheet material is that color is even, its shortcoming is that surface does not neutralize when doing chemical treatment, oxidation reaction is slowly carried out in weathering steel surface always, clear varnish temporary buffer that surface the is done secondary oxidation time, but can rust be returned at any time, the clear varnish on the broken surface of arch, produces bubbling, peels off.Peeled-off portion can continue be oxidized and fall slag, until rust is logical.
In sum, for overcoming the above-mentioned defect existed in prior art, the utility model proposes a kind of weathering steel thermal insulating composite panel, it has energy-saving and environmental protection, economical and practical advantage, uses middle color even, does not play slag, do not come off.
Utility model content
The weathering steel thermal insulating composite panel that the utility model provides, first selection, weathering steel preferably adopts the weathering steel material of the label S355 JOWP model of Italian import, because the composition of the inside institute cupric is relatively domestic higher, other composition is more stable, and most important reason impurity is fewer.The great advantage of this kind of sheet material is selected to be that oxidant and technique can well the oxidation course of control surface and the changes of pattern.
The weathering steel thermal insulating composite panel that the utility model provides comprises the sheet material of two pieces of end bendings, and fill insulant material between sheet material, is sealed by weather strip between the bending part at sheet material two ends.
Wherein, sheet material comprises panel and backboard, with the weathering steel bending of 1.2mm or 2.0mm, makes panel, the zinc-plated weathering steel that backboard 1.2mm is thick, and middle heat insulating material polyurethane heat insulation material is filled, and PVC weather strip selected by weather strip.
In addition, the surface of panel arranges acidic oxidation agent topping.
The concrete set-up mode of acidic oxidation agent topping is the acidic oxidation agent of researching and developing in surface hairbrush light brush one deck Wei Lesen company of panel; preferred placement naturally 15 days; the surface of panel forms oxide layer fast, and produce that weathering steel has by oneself rust, produce the lines of similar wood grain simultaneously.Afterwards, again polish on the surface of panel, the floating rust on surface is destroyed, again carries out smearing of acidic oxidation agent, preferably naturally place 7 days, now weathering steel surface and deep layer all produce stable topping.
By the process of twice in early stage, last one combined alkali liquid is smeared on surface again, neutralization remaining acid oxidant in early stage.
The utility model has following beneficial effect relative to prior art: the weathering steel thermal insulating composite panel that the utility model provides, the weathering steel bending of 1.2mm or 2.0mm is adopted to make panel, the zinc-plated weathering steel thick with 1.2mm makes backboard, do not play slag, do not peel off, color nature, has good decay resistance and decorative effect, the different spaces such as facade, indoor partition can be applied in, use more energy-conservation, economy, environmental protection.
Accompanying drawing explanation
The structural representation of the weathering steel thermal insulating composite panel that Fig. 1 provides for the utility model.
In figure: 1 sheet material 2 heat insulating material 3 weather strip.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
The weathering steel thermal insulating composite panel that the utility model provides comprises the sheet material 1 of two pieces of end bendings, and weathering steel selected by described sheet material 1, and fill insulant material 2 between sheet material 1 is sealed by weather strip 3 between the bending part at sheet material 1 two ends.
Wherein, sheet material 1 comprises panel and backboard, makes panel with the weathering steel bending of 1.2mm or 2.0mm, the zinc-plated weathering steel that backboard 1.2mm is thick, and middle heat insulating material 2 polyurethane heat insulation material is filled, weather strip 3 PVC weather strip.
In addition, the surface of panel arranges acidic oxidation agent topping.
The concrete set-up mode of acidic oxidation agent topping is the acidic oxidation agent of researching and developing in surface hairbrush light brush one deck Wei Lesen company of panel; preferred placement naturally 15 days; the surface of panel forms oxide layer fast, and produce that weathering steel has by oneself rust, produce the lines of similar wood grain simultaneously.Afterwards, again polish on the surface of panel, the floating rust on surface is destroyed, again carries out smearing of acidic oxidation agent, preferably naturally place 7 days, now weathering steel surface and deep layer all produce stable topping.By the process of twice in early stage, last one combined alkali liquid is smeared on surface again, neutralization remaining acid oxidant in early stage.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
