Abstract
The utility model discloses a tectorial membrane colorful steel plate belongs to various steel sheet technical field, and it includes steel sheet substrate and the coating finish paint layer on the steel sheet substrate, characterized in that: the fusion pressure has the pad pasting on the finish paint layer, pad pasting ab intra is to being equipped with hot melt adhesive resinous coat, binder layer and PET layer outward in proper order, the hot melt adhesive resinous coat passes through binder layer bonding on the PET layer. The various steel sheet of this kind has the close prevention of seepage of matter and loses, is able to bear or endure high microthermal characteristic because PET belongs to the polymer plastic material, and hot carry over factor far is lighter than the steel sheet, so this pad pasting helps improving the thermal -insulated corrosion resisting property of various steel sheet, through binder layer and the hot melt adhesive resinous coat back that bonds, can through hot melt adhesive resinous coat hot melt on the finish paint layer of various steel sheet, simple process and firm in connection.
Description
Technical field
The utility model belongs to color steel technical field, is specifically related to a kind of overlay film color steel sheet.
Background technology
Color steel, owing to having the good characteristics such as lightweight, attractive in appearance, easy-formation and mechanical strength be high, becomes in recent years by one of the brand-new material of praising highly, is widely used in household electrical appliances, decoration, building, office furniture and other industry.
Current color steel adopts mostly to be made in the mode of the colored finish paint of the surface spraying of steel plate, in the application of the particular surroundings such as some humidity, color steel is easily corroded, have a strong impact on its service life, cause color steel application to be in this context restricted, substantially reduce the range of application of color steel.
For above-mentioned present situation, need the color steel that those skilled in the art research and develop a kind of withstand corrosion badly, to widen its application.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of overlay film color steel sheet, can strengthen its heat-insulating corrosion-resistant performance.
For solving the problems of the technologies described above, the technical solution of the utility model is: invent a kind of overlay film color steel sheet, comprise substrate of steel plate and be coated in the top coat layer on substrate of steel plate, it is characterized in that: on described top coat layer, fusion pressure has pad pasting, described pad pasting is provided with PUR resinous coat, adhesive layer and pet layer from the inside to the outside successively; Described PUR resinous coat is bonded on pet layer by adhesive layer.
Preferably, also fireproof coating and cenosphere is contained in described top coat layer.
Preferably, described PUR resinous coat is one or more in polyurethane resin, mylar and polyurethane termoplastic elastomer resin.
Preferably, described adhesive layer is weatherability transparent glue.
Preferably, described pad pasting is also provided with transparent protective film.
Preferably, described transparent protective film is UV diaphragm.
Preferably, described substrate of steel plate is zinc-plated substrate, aluminum-zinc alloy substrate or cold-rolled substrate.
Preferably, the two sides of described substrate of steel plate is equipped with top coat layer and pad pasting.
Compared with prior art, the beneficial effects of the utility model are:
1, because pad pasting is provided with PUR resinous coat, adhesive layer and pet layer from the inside to the outside successively; Described PUR resinous coat is bonded on pet layer by adhesive layer, and PET belongs to high molecule plastic material, have the characteristic that erosion, high-low temperature resistant are oozed in matter tight defense, heat transfer coefficient is much smaller than steel plate, therefore this pad pasting contributes to the heat-insulating corrosion-resistant performance improving color steel; After being bondd by adhesive layer and PUR resinous coat, can by PUR resinous coat hot melt on the top coat layer of color steel, technique is simple and be connected firmly.
2, owing to also containing fireproof coating in top coat layer, can contribute to the fire protecting performance improving color steel, the hollow-core construction that cenosphere has then can improve the heat-proof quality of color steel.
3, due to pad pasting being also provided with transparent protective film, be beneficial to protection pad pasting, extend its service life.
4, the utility model structure is simple and firmly can be connected with color steel, enhances the fire prevention of color steel, heat insulation and corrosion resisting property, widens its range of application, be more convenient to applying of color steel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral is: 1, zinc-plated substrate; 2, top coat layer; 3, PUR resinous coat; 4, adhesive layer; 5, pet layer; 6, UV diaphragm.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Side near substrate of steel plate is defined as inner side by the utility model, correspondingly the opposite side away from substrate of steel plate is defined as outside.
The utility model is coated with the top coat layer 2 that thickness is 10 ~ 70um on zinc-plated substrate 1, is specifically as follows 10um, 20um, 40um, 60um or 70um.Also containing fireproof coating and cenosphere in top coat layer 2, fireproof coating can contribute to the fire protecting performance improving color steel, and the hollow-core construction that cenosphere has then can improve the heat-proof quality of color steel.On top coat layer 2, fusion pressure has pad pasting, and pad pasting is provided with PUR resinous coat 3, adhesive layer 4 and pet layer 5 from the inside to the outside successively; PUR resinous coat 3 is by being bonded on pet layer 5.The thickness of PUR resinous coat 3 is 0.01 ~ 10um, is specifically as follows 0.01um, 3um, 5um, 8um or 10um.The thickness of adhesive layer 4 is 0.01 ~ 5um, is specifically as follows 0.01um, 3um or 5um.The thickness of pet layer 5 is 12 ~ 50um, is specifically as follows 12um, 20um, 30um, 40um or 50um.PUR resinous coat 3 used is polyurethane resin, and adhesive layer 4 is weatherability transparent glue.
In order to extend the service life of pad pasting, also on pad pasting, be also provided with transparent protective film, transparent protective film is UV diaphragm 6.The thickness of UV diaphragm 6 is 0.05 ~ 5um, is specifically as follows 0.05um, 3um or 5um.
PUR resinous coat 3, except selecting above-mentioned polyurethane resin, also can select mylar or polyurethane termoplastic elastomer resin, or any combination of above-mentioned three.
Top coat layer 2 and pad pasting all can also be arranged on the two sides of substrate of steel plate, form the full protection to substrate of steel plate, and substrate of steel plate, except the zinc-plated substrate 1 adopted in above-described embodiment, also can adopt aluminum-zinc alloy substrate or cold-rolled substrate.
