Problems solved by technology

[0002] The refrigerator door body is usually formed by injecting foaming material into a device composed of a mold and a door panel. Due to the voids between the foam layer and the door panel, foam flow traces, and the different shrinkage coefficients between the foam layer and the door panel, It will leave irregular marks on the appearance of the door body, resulting in poor appearance of the door body

Embodiment 1

[0086] Such as Figure 1 to Figure 3 As shown, the embodiment of the first aspect of the present invention proposes a casing 100, including: a body 110, a first foam layer 120, and an isolation layer 130, wherein the first foam layer 120 and the body 110 are integrated by foaming Forming, the isolation layer 130 is disposed between the body 110 and the first foam layer 120 , and the adhesion of the material of the isolation layer 130 is greater than the adhesion of the material of the first foam layer 120 .

[0087] Specifically, such as figure 2 with image 3 As shown, the first foam layer 120 and the body 110 are integrally formed by foaming, the isolation layer 130 is arranged between the body 110 and the first foam layer 120, and the adhesion of the material of the isolation layer 130 is greater than that of the first foam layer The adhesion of the material of 120 makes the isolation layer 130 and the body 110 have higher adhesion, which can avoid the direct contact bet...

Embodiment 2

[0089] Such as Figure 1 to Figure 3 As shown, in one embodiment of the present invention, the casing 100 includes a body 110, a first foam layer 120 and an isolation layer 130, wherein the isolation layer 130 is a second foam layer or coating.

[0090] In this example, if figure 1 with figure 2 As shown, on the one hand, the isolation layer 130 is the second foam layer, that is, the isolation layer 130 and the body 110 are integrally formed by foaming. Specifically, after the isolation layer 130 and the body 110 are integrally formed by foaming, an isolation layer The main body 110 and the first foam layer 120 of 130 are integrally formed through foaming again; The main body 110 of the layer and the first foam layer 120 are integrally formed by foaming, and the different structures of the isolation layer 130 can meet the requirements of different processing techniques of the isolation layer 130, and at the same time, can meet the requirements of different materials of the ...

Embodiment 3

[0096] Such as Figure 1 to Figure 3 As shown, in an embodiment of the present invention, on the basis of the above-mentioned embodiment 2, further, the material components of the isolation layer 130 include: polyether polyol, 1,4-butanediol, foaming catalyst, silicone oil , water, toluene diisocyanate, curing catalyst, trimerization catalyst.

[0097]In this embodiment, the material components of the isolation layer 130 include polyether polyol, 1,4-butanediol, foaming catalyst, silicone oil, water, toluene diisocyanate, curing catalyst, and trimerization catalyst. The material composition of layer 130 makes the isolation layer 130 formed be flexible polyurethane foam, and flexible polyurethane foam has higher adhesive force, meanwhile, flexible polyurethane foam is mostly open cell structure, and resilience is good, makes isolation layer 130 There is no air bubble between the body 110 and the isolation layer 130 itself does not shrink after curing, thereby ensuring a high a...

Abstract

The invention provides a shell, a manufacturing method of the shell and a household appliance. The shell comprises a body, a first foaming layer and an isolating layer, wherein the first foaming layerand the body are integrally formed in a foaming manner, the isolating layer is arranged between the body and the first foaming layer, and adhesive force of a material of the isolating layer is largerthan adhesive force of a material of the first foaming layer. According to the shell, the isolating layer is arranged between the body and the first foaming layer, the adhesive force of the materialof the isolating layer is larger than the adhesive force of the material of the first foaming layer, thus the isolating layer and the body have high adhesive force, the situations that in the relatedtechnology, a first foaming layer directly makes contact with a body, due to vacuoles between the first foaming layer and the body, foam flowing cracks and the difference between shrinkage coefficients of the first foaming layer and the body, appearance of the body is poor can be avoided, and the appearance quality of the body is improved greatly.

Description

technical field [0001] The present invention relates to the technical field of household electrical appliances, in particular to a casing, a method for preparing the casing, and a household electrical appliance. Background technique [0002] The refrigerator door body is usually formed by injecting foaming material into a device composed of a mold and a door panel. Due to the voids between the foam layer and the door panel, foam flow traces, and the different shrinkage coefficients between the foam layer and the door panel, It will leave irregular marks on the appearance of the door body, resulting in poor appearance of the door body. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] To this end, a first aspect of the invention proposes a housing. [0005] The second aspect of the present invention proposes a method for preparing a casing. [0006] A third aspe...
