Abstract

The invention discloses an anti-shrinkage-deformation refrigerator door body, and relates to the technical field of refrigerators. The refrigerator door body comprises a refrigerator door shell, decorative strips are fixedly connected to the two ends of the refrigerator door shell, a plurality of reinforcing pieces are fixedly connected to the inner wall of the refrigerator door shell, and the reinforcing pieces are of tubular structures and are arranged in the length direction of the refrigerator door shell; and a plurality of air holes are formed in the side walls of the reinforcing pieces,and the surfaces of the reinforcing pieces are fixedly connected with breathable adhesive tapes for covering the air holes. According to the refrigerator door shell, through arranging the tubular reinforcing pieces, the supporting strength of the refrigerator door shell is effectively improved, and the problem that an existing refrigerator door shell is prone to shrinkage deformation is solved. Meanwhile, the air holes are formed and covered with the breathable adhesive tapes, and gas generated in the foaming process can be discharged out of the door body through the air holes, so that the quality defects of gas gathering, empty materials and the like in the foaming process are effectively avoided, and the surface flatness of the refrigerator door shell is further improved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerator door body capable of preventing shrinkage and deformation. Background technique [0002] Among the refrigerator door panels, steel doors account for an increasing proportion, especially for export refrigerators, which are dominated by steel doors. The ever-changing steel plate surface treatment technology has enriched the appearance of steel plate refrigerators and improved the product grade. [0003] However, after the steel plate door is foamed, uneven quality defects will appear on the surface to varying degrees, which will affect the product appearance and quality reputation. In order to solve this problem, most enterprises improve the compatibility of the foam material and the surface material of the door body by improving the formula of the door body foam material, and then improve the flatness of the door body surface. Some enterprises th...
