Abstract
The utility model discloses a deformation -proof refrigerator door body, including door shell, door courage and foaming layer, the foaming layer lies in between door shell and the door courage, still is equipped with the compound felt layer of one deck between door shell and the foaming layer, and compound felt layer includes outer viscose layer, felt basic unit, interior viscose layer, raw paper layer that outside -in connected gradually, and the outer viscose layer and the door shell on compound felt layer bond, and the raw paper layer and the foaming layer on compound felt layer bond. The utility model discloses it has following advantage to compare prior art: the utility model discloses setting up compound felt layer between door shell and foaming layer, keeping apart door shell and foaming layer, the shrinkage stress of the foam of foaming layer is disperseed, is absorbed to the one side, solved because of the door shell surface irregularity problem that the foam shrink led to the fact, and on the other hand, compound felt layer and door shell and foaming layer are glued as an organic wholely, solution door shell unsticking, swell problem to prevented that the refrigerator door shell warp, making this refrigerator door surfacing, not having and warp, appearance quality is good.
Description
Technical field
The utility model relates to refrigeration appliance technical field, in particular a kind of deformation-proof refrigerator door body.
Background technology
Generally speaking, when refrigerator door foaming is produced, expanding foam solution and door shell, door courage directly bond, after door foaming is placed, foaming layer can shrink distortion, thus generation shrinkage stress, easily produce uneven problem on deformation on door shell edge stress concentrated position door shell surface, affect the external appearance quality of door, particularly clamshell doors large refrigerator door body, because door body size is comparatively large, shrinkage stress is large, and the performance of door shell areal deformation problem is more obvious.For improving this problem, generally paste barrier paper or adhesive tape at deformation position door shell inner surface, but door shell problem on deformation improves DeGrain, the easy unsticking of door shell, bulge sometimes, causes a body secondary defect, affects product appearance.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of deformation-proof refrigerator door body.
The utility model is achieved through the following technical solutions:
A kind of deformation-proof refrigerator door body, comprise door shell, door courage and foaming layer, described foaming layer is between described door shell and door courage, one deck compound felt layers is also provided with between described door shell and described foaming layer, described compound felt layers comprises outer adhesive-layer, felted fabric backing, interior adhesive-layer, the original paper layer that ecto-entad connects successively, the outer adhesive-layer of described compound felt layers is bonding with described door shell, described compound felt layers original paper layer bonding with described foaming layer.
The thickness of described compound felt layers is 0.5 ~ 4mm.
The utility model has the following advantages compared to existing technology:
1, a kind of deformation-proof refrigerator door body of providing of the utility model, compound felt layers is set between door shell and foaming layer, door shell and foaming layer are isolated, the shrinkage stress of the foam of dispersion on the one hand, absorption foaming layer, solve the door shell surface irregularity problem because foam contraction causes, on the other hand, compound felt layers and door shell and foaming layer stick to one, solve door shell unsticking, bulge problem, thus prevent refrigerator door to be out of shape; Make this refrigerator door surfacing, without distortion, presentation quality is good.
2, this refrigerator door manufacturing process is simple, easy to implement, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present utility model.
Fig. 2 is the cross-sectional structure schematic diagram of compound felt layers of the present utility model.
Number in the figure: 1 door shell, 2 courages, 3 foaming layers, 4 compound felt layers, 41 felted fabric backings, 42 outer adhesive-layers, adhesive-layer in 43,44 original paper layers, 45 barrier papers.
Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
See Fig. 1 and Fig. 2, a kind of deformation-proof refrigerator door body that the present embodiment provides, comprise door shell 1, door courage 2 and foaming layer 3, foaming layer 3 is between door shell 1 and door courage 2, one deck compound felt layers 4 is also provided with between door shell 1 and foaming layer 3, compound felt layers 4 comprises outer adhesive-layer 42, felted fabric backing 41, interior adhesive-layer 43, the original paper layer 44 that ecto-entad connects successively, and the outer adhesive-layer 42 of compound felt layers 4 is bonding with door shell 1, compound felt layers 4 original paper layer 44 bonding with foaming layer 3.The thickness of compound felt layers 4 is preferably 0.5 ~ 4mm.
In the present embodiment, the manufacture method of deformation-proof refrigerator door body is:
A, subsides compound felt layers 4: compound felt layers 4 one side before pasting is original paper layer 44, another side is barrier paper 45, first the barrier paper 45 of compound felt layers 4 is torn, expose outer adhesive-layer 42, and this outer adhesive-layer 42 is attached on door shell 1 inner surface of forming;
B, dress door body decorative strip: panel, lower panel on door body are stuck in door shell about 1 two ends, and blend compounds band is fixed;
C, leak stopping: tape at door shell 1 and panel seam crossing and carry out leak stopping, in case foaming leakage;
D, foaming: the door shell 1 assembled puts into the counterdie of foaming mould, door courage 2 snaps in the patrix of foaming mould, after material feeding, matched moulds, curing molding, namely makes this deformation-proof refrigerator door body.
The present embodiment can according to different door shell 1 structures, and adopt the compound felt layers 4 of different size, make the deformation-proof refrigerator door body of different size, specification, obtained door surface is smooth, and without distortion, presentation quality is good.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
