Problems solved by technology

Therefore, the bonding operation is very cumbersome, and the operation time is long and the cost is high.
[0006] In addition, if it is not desired to remove the surface treatment layer 12, in order to obtain the adhesive force that meets the purpose, it is necessary to analyze the composition of the painted object and find out the characteristics of the adhesive that can be painted on the smooth painted surface, which requires a lot of money. time, and sometimes sufficient adhesion cannot be guaranteed

Embodiment Construction

[0021] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0022] Fig. 4 is a schematic cross-sectional view of a shell plate according to an embodiment of the present invention. As shown in Fig. 4, the shell plates 10' of home appliances such as refrigerators and washing machines used in the embodiment of the present invention include: a relatively high-strength steel plate 11 that can protect the internal structure under external impact, and is formed on the outside of the home appliances. The outer surface of the steel plate 11, the surface treatment layer 12 that is galvanized, is formed on the inner surface of the steel plate 11 that is not exposed to the outside, and is coated with an adhesive ( Hotmelt) adhesive layer 100.

[0023] The surface treatment layer 12 can be a galvanized layer, or an acrylic or polyurethane series coating treatment layer.

[0024] The adhesive layer 100 can be made o...

Abstract

This invention relates to a shell plate of a household appliance including a steel plate coated with an adhesive layer of thermal plastic resin generating adhesive force when being heated on its one side, in which, the thermal plastic resin is HDPE or LDPE and the thickness of the coated adhesive layer is 0.1mm to 1mm and the layer is coated on a part or the whole of one side of the steel plate not exposed to outside and the other side is plated with Zn or coated with polyurethane. The invented adhesive layer is formed by thermal plastic resin generating adhesive force by heat and the plate can be adhered to an object only by heating it in terms of a certain melting point temperature, which can play the role of coating.

Description

technical field [0001] The invention relates to a household electrical appliance. In particular, it relates to a housing plate for home appliances that can not only prevent corrosion on the surface of steel plates constituting the exterior of home appliances, but also reduce costs. Background technique [0002] For home appliances such as refrigerators, PCM (Pre Coated Metal: PCM), which is based on steel with sufficient strength and coated with an anti-corrosion film on the surface, or plastic Thin mold steel (Vinyl Coated Metal), or ordinary galvanized steel. [0003] Fig. 1 is a schematic diagram of a refrigerator shell; Fig. 2 is a cross-sectional view of the X-X line of Fig. 1 with a traditional heat insulation structure; Fig. 3 is a schematic cross-sectional view of the shell plate of Fig. 1 . As shown in the figure, as a household appliance, a refrigerator casing 1 includes an outer casing 10 made of a steel plate 11 that can protect its internal structure from exte...
