Description

Refrigerator door body capable of preventing foaming shrinkage deformation

Technical Field

The invention belongs to the technical field of refrigerator door bodies, and particularly relates to a refrigerator door body capable of preventing foaming shrinkage deformation.

Background

In the refrigerator panel, the steel plate door accounts for more and more, and especially the steel plate door is the main thing in the export refrigerator. The steel plate surface treatment technology which is different day by day enriches the appearance of the steel plate door refrigerator and improves the product grade. However, after the steel plate door is foamed, the surface of the steel plate door has uneven quality defects to different degrees, and the appearance and quality of the product are influenced. In order to solve the problem, some enterprises thicken the plate and improve the capability of resisting shrinkage deformation of the plate. Some enterprises paste buffering isolation material in door shell inside, weaken because of the shrink of foaming material to the adverse effect that the door shell caused. The method reduces the probability of shrinkage deformation of the steel plate door after foaming, but the degree is very limited. And the thickening of the plate and the sticking of the buffering and isolating material can greatly increase the cost of the door body, and the market competitiveness of the product cannot be effectively improved. Therefore, the continuous improvement of the surface flatness of the foamed steel plate door is still a great problem for enterprises.

In order to solve the problems, the invention provides a refrigerator door body capable of preventing foaming shrinkage deformation.

Disclosure of Invention

The invention aims to provide a refrigerator door body capable of preventing foaming shrinkage deformation, which ensures that gas generated in the foaming process of the refrigerator door body is smoothly discharged through micropores by carving the micropores on the surface of the refrigerator door body, and effectively avoids quality defects such as gas accumulation, material vacancy and the like in the foaming process.

In order to solve the technical problems, the invention is realized by the following technical scheme:

the invention relates to a refrigerator door body capable of preventing foaming shrinkage deformation, which comprises a refrigerator door body,

the refrigerator door body is formed by bending a steel plate shell; micro holes are carved on the surface of the refrigerator door body; a breathable film is pasted on the outer surface of the refrigerator door body; and the inner surface of the refrigerator door body is adhered with grid cloth.

Preferably, the micropores are less than 0.1mm in diameter.

Preferably, the breathable film is printed with a texture.

Preferably, the grid cloth is made of nylon or terylene; through holes with the same shape are uniformly distributed on the surface of the grid cloth.

Preferably, the through holes of the grid distribution surface are square through holes with the diameter of 2 x 2 mm.

One aspect of the present invention has the following advantageous effects:

1. according to the invention, the micropores are engraved on the surface of the refrigerator door body, so that gas generated in the foaming process of the refrigerator door body is smoothly discharged through the micropores, quality defects such as gas accumulation, material vacancy and the like in the foaming process are effectively avoided, and the surface flatness of the door body is improved.

2. According to the refrigerator door body, the breathable film is adhered to the outer surface of the refrigerator door body, so that gas generated in the foaming process of the door body can be effectively discharged to the outside of the door body; meanwhile, the breathable film is printed with textures and colors, so that the steel plate is endowed with unique appearance.

3. The inner surface of the refrigerator door body is stuck with grid cloth; the condition that the bubbles produced is destroyed, so that the bubbles can not be agglomerated on the surface of the steel plate, the foaming material can be uniformly and compactly bonded with the door shell, and the problem that the surface of the door body is uneven after foaming is effectively solved.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
