Abstract
The invention discloses a method for the tight connection of a metal sheet and a foaming layer, characterized in that: an elastic material layer is arranged on a contact surface of a sheet and the foaming layer prior to foaming the metal sheet; and the foaming layer is generated by normal foaming operation after the elastic material layer is arranged. The method is very simple and has no need of complex operation, and only an elastic material layer is hot molten on the surface of the metal sheet prior to foaming; when the metal sheet is externally impacted, the elastic material layer can disperse the applied force so that the metal sheet is not liable to separation between the sheet and the foaming layer when being impacted tremendously. Thus, the connection between the metal sheet and the foaming layer is firmer.
Description
Technical field
What the present invention relates to is method of attachment between a kind of sheet metal and the foaming layer, is specifically related to firm, the shock proof connection between sheet metal and the foaming.
Background technology
Sheet metal comprises the needs for the product heat-insulating property in the process of making processing such as stainless steel materials, aluminium plate, and foaming layer is set in the middle of the framework that the sheet material of being everlasting is made.Be connected the bonding force that relies on adhesive between foaming layer and the sheet metal.So rely on the effect of this bonding force can not make between sheet metal and the foaming layer links together very closely owing to the sheet metal surface is very smooth.In a single day the finished product of producing like this runs into outside impact will produce bad results such as layering in the part of impacting.Especially ought run into external impact energetically and be connected bad results such as more significantly layering to occur between sheet metal and the foaming layer when making sheet metal produce local deformation.These results' generation all be by between sheet metal and the foaming layer to be connected power not strong, cause a little less than the impact resistance.
This situation often occurs in similar container industry, forms foaming layer as freezing and frozen products insulated container in order to be incubated just must foam in the framework of being made by sheet metal and skeleton.The heat insulation effect of container just can meet the demands like this, and to reel be unavoidable thing but container is in the process of transportation.So the surfaces externally and internally of container is bruised through regular meeting, thereby cause bad result such as cracking, layering between the foaming layer of internal container and the container wall panel, will influence the heat insulation effect of container like this.And if the damage of this respect appears between foaming layer and the metal wallboard, repair very difficulty.
So never a good way solves this part problem, this technical barrier has caused very big puzzlement for the technical staff of the sector.
Summary of the invention
At the deficiency of prior art, the invention provides the close-connected method of a kind of sheet metal and foaming layer, this method is simple, and bonding strength and shock resistance increase.
Another object of the present invention is the syndeton that a kind of sheet metal and foaming layer also are provided, and this structure connects closely.
Below introduce a kind of sheet metal of the present invention and the close-connected method of foaming layer in detail, sheet metal was provided with an elastomeric layer on the contact-making surface of sheet material and foaming layer before foaming; Treat to carry out again after this elastomeric layer is finished normal foaming operation and produce foaming layer.
Optimize, above-mentioned elastomeric layer adopts the method for hot melt to be arranged on the sheet metal.
Optimize, above-mentioned sheet metal is provided with 30-100 gram rubber for every square metre.
Optimize, above-mentioned elastomeric layer adopts spider web structure or tiling uniformly to be provided with.
Be provided with one between the close-connected structure of a kind of sheet metal and foaming layer, sheet metal and foaming layer and be used to strengthen being connected and disperseing stressed rubber layer.
Optimize, above-mentioned elastomeric layer adopts spider web structure or tiling structure.
Advantage of the present invention is; At first very simply it need not complicated operations to this method, only need get final product by surperficial hot melt one rubber layer at sheet metal before foaming; The adhesion of sheet metal and foaming layer is improved greatly.Secondly, when sheet metal during by external impact this rubber layer can disperse stressedly, make sheet metal when being subjected to bigger impact, be not easy layering between sheet material and foaming layer.So that being connected between sheet metal and the foaming layer is more firm.
Description of drawings
Fig. 1 is the main cutaway view of one embodiment of the present of invention;
Fig. 2 is the partial enlarged drawing of the A part of Fig. 1.
The specific embodiment
Below in conjunction with Figure of description the present invention is done further disclosure.
Embodiment 1:
The close-connected method of a kind of sheet metal and foaming layer is an example with freezing and frozen products insulated container, sees also Figure of description 1 and Fig. 2, and container is made of framework and the endothelium and the crust that are installed on the framework; Wherein endothelium comprises interior plate, inside ceiling panel and aluminium floor; Crust comprises outer panel, roof sheet and Outer Bottom Plating.All the other all are to be made by stainless steel materials except that aluminum soleplate, inside ceiling panel.Between endothelium and crust, adopt foam process that foaming layer is set.The sheet metal 1 of endothelium and crust was provided with an elastomeric layer 2 on the contact-making surface of sheet material and foaming layer 3 before foaming, this elastomeric material sees that at present reasonable scheme is to adopt rubber; Treat to carry out again after this rubber elastomeric layer 2 is finished normal foaming operation and produce foaming layer 3.Elastomeric layer 2 adopts the method for hot melt that 30-100 gram rubber is set on every square metre of sheet metal, and present embodiment adopts 60 gram rubber are set on every square metre of sheet metal.
These elastomeric layer 2 general thermoplastic elastomers that adopt require this rubber that ductility is arranged.So the rubber of present embodiment is that the model of being produced by Switzerland SIKA (west card) company is the rubber of SIKAMELT-9285MC.Paste better in order to make rubber layer that optimal scheme is that rubber layer is arranged to the spider web structure on sheet metal; Certainly rubber layer to be arranged to common uniform tiling structure also passable.
Just formed a kind of new sheet metal and the close-connected structure of foaming layer through above-mentioned method, its concrete structure is to be provided with one to be used to strengthen being connected and disperseing stressed elastomeric layer 2 between sheet metal 1 and foaming layer 3.
There is the newly-installed rubber layer of this layer just to solve foaming layer and the not strong shortcoming of sheet metal adhesion, but also can have disperseed outside impulsive force, made between sheet metal and the foaming layer to be difficult for layering.Increased the service life of container, and this method need not very simply to carry out bigger technology adjustment, cost is also low; Solved insoluble all the time actual techniques problem.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
