Description
Technical field:
The utility model relates to a kind of environment-friendly type lagging metal structure, can use the lagging metal surface at electronics shell or building materials, produces kinds of surface sense of touch, wear-resisting, the good metal plate structure that has the visual appearance effect concurrently of adherence.
Background technology:
The lagging metal structure generally all contains the PVC skin membrane at present, the PVC skin membrane because raw material in the process that is processed into the PVC epithelium, can produce noxious material because of heating, belong to non-ep-type material, and the PVC epithelium generally all can add plasticizer, and the time has plasticizer too for a long time and disengages, and changes shortcomings such as its original rerum natura, if the then necessary resin bed that is coated with or follows another material in the surface of smooth abrasion-proof will be arranged, as: polyester resin etc.
Therefore, as No. 404888 patent of invention case of TaiWan, China patent announcement: " a kind of resin-coated metal sheet ", be primarily characterized in that: " on the substrate of a metal material, laminated in regular turn dope layer, sex change olefin resin layer D, style or comprehensive printed layers C that 5～100mm is thick, following layer B, and the resin-coated metal sheet that forms of the thick clear polymer based resin film A of 5～100mm; The sex change olefin resin layer that the centre of laminated resin is set is with the then property excellence of printed layers, dope layer, polyester based resin film etc., even so under harsh processing such as deep-draw, constitute peeling off of place, bed boundary the processing adherence of tool excellence also can not take place.
Again, metal sheet surface is coarse or respectively formation layer (resin bed) concavo-convex, absorbed by the sex change olefin layer, therefore, as resin-coated metal sheet, can obtain excellent clarity, its roll extrusion process of the processing mode of this kind structure is loaded down with trivial details, resin bed by two kinds of materials makes up again, more not unification of process, and sex change alkene has plenty of non-environmental protection material.
Because the metal sheet of common coated with resins still has aforementioned disappearance, the inventor studies improved method at these shortcomings, and generation of the present utility model is arranged finally.
The utility model content:
Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, a kind of environment-friendly type lagging metal structure is provided, it is to apply the skin membrane that an adhesion agent layer, a polyurethane surface layer and polyurethane bottom constitute on metal substrate, utilize layer of polyurethane easily to combine, make skin membrane and metal substrate have good adherence with adhesion agent layer.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of environment-friendly type lagging metal structure, and it comprises a metal substrate, reaches an adhesion agent layer; Be characterized in: also comprise a cortex film, described adhesion agent layer is coated at least one side surface of described metal substrate, this skin membrane places on the adhesion agent layer and combines with the metal substrate adherence by adhesion agent layer, and this cortex film is by a polyurethane bottom and the stacked in regular turn be combined into of polyurethane surface layer.
So, can make skin membrane and metal substrate have good adherence, wear-resisting characteristic, and the polyurethane skin rete can produce kinds of surface sense of touch and visual appearance effect; Because the polyurethane material itself has good wearability, different surface touch, wear-resisting, adherence is good has effect attractive in appearance concurrently, and the unification of this kind polyurethane resin material, changeableization of kenel, compliance with environmental protection requirements, and handling ease.
As for detailed construction of the present utility model, the effect of utilization principle and generation then with reference to the explanation of leu icon down, can reach completely and understand:
Description of drawings:
Fig. 1 is a section of structure of the present utility model.
The specific embodiment
Seeing also Fig. 1, is section of structure of the present utility model, and figure can find out thus: the utility model mainly comprises: metal substrate 1, adhesion agent layer 2, and skin membrane 3 etc. partly; Wherein said metal substrate 1 is the stock of a lagging metal, the sheet metal that can be plated steel sheet, cold-rolled steel sheet, corrosion resistant plate, aluminium sheet, almag and alumal and/or handled through epithelium on it, select according to the difference way, as be used in case of electronic device, general more suitable with the good metal aluminum sheet of light weight intensity; Described adhesion agent layer 2 compositions can be mylar, acrylic resin and/or polyurethane resin, are coated at least one side surface of aforementioned metal substrate 1 with adhesion agent layer 2 suitable thickness, and are heated between 140 ℃～210 ℃, make adhesion agent layer 2 suitably softening; And skin membrane 3 more comprises: a polyurethane bottom 31, the stacked in regular turn be combined into of a polyurethane surface layer 32, skin membrane 3 is put on adhesion agent layer 2, make with adhesion agent layer 2 with polyurethane bottom 31 and to contact, multiple cool off then, make skin membrane 3 utilize adhesion agent layer 2 to combine with metal substrate 1 adherence with a minute surface roller roll extrusion that is heated between 180 ℃ by room temperature.
In the aforementioned skin membrane 3, because polyurethane surface layer 32 can be formed according to different formulations, reach the processing procedure difference and different surface touch (as: changeableization of material kenel arranged, lines, smooth surface effect etc.), and polyurethane bottom 31 also can replace with the polyurethane foam layer, increase sense of touch, also available polyurethane printed layers replaces, make and have effect attractive in appearance, and polyurethane surface layer 32 or polyurethane bottom 31 also can add metal dust (as: aluminium powder etc.), more than pearl essence or pigment are any, increase the visual sense aesthetic feeling, and the adhesion agent layer 2 between the polyurethane bottom 31 in metal substrate 1 and the skin membrane 3 can make it have stable adherence effect.
Below be aided with experimental example, the effect that the utility model structure can be reached be described:
Experimental example one:
At thickness is on the aluminium sheet of 0.5mm, be coated with the polyurethane resin adhesion agent layer 2 of 21 μ m, and baking metal substrate 1, to the plate temperature be 166 ℃, the skin membrane 3 that is combined into for ganoid surface layer as bottom, polyurethane surface layer 32 for printed layers by polyurethane bottom 31 is with the roll extrusion of minute surface roller, found that peel strength is 8.52N/cm, there is good slickness on the epithelium surface, the no any generation of peeling off of hundred lattice test, and adherence is good.
Experimental example two:
At thickness is on the aluminium sheet of 0.8mm, be coated with the adhesion agent layer 2 of 32 μ m polyurethane resins, and baking metal substrate 1, to the plate temperature be 193 ℃, by polyurethane bottom 31 for bottom, polyurethane surface layer 32 for adding the skin membrane 3 that aluminium powder and surperficial textured surface layer are combined into, with heating the roll extrusion of minute surface roller after cool off again, found that peel strength is 13.82N/cm, there are sense of touch and visual sense of beauty in the epithelium surface, the no any generation of peeling off of hundred lattice test, and adherence is good.
By as can be known aforementioned, the utility model environment-friendly type lagging metal structure has compliance with environmental protection requirements really, processing is simple and easy and skin membrane can have different surface touch (as: changeableization of material kenel, lines, smooth surface effect etc.), have good adherence, wearability, also can produce effect attractive in appearance, and skin membrane resin material unification, had usability, novelty and progressive on the industry, the important document that meets patent application proposes utility application in accordance with the law.
