Decoration strip for refrigerator and production process thereof

Abstract

The invention discloses a decoration strip for a refrigerator and a production process thereof, and relates to the technical field of refrigeration equipment. The decoration strip is formed through IMD process extrusion molding, and sequentially comprises a base material layer, a vacuum coating layer and a PET film layer from the inner side to the outer side, the base material layer is made of ABS, the PET film layer is of a double-layer structure, the inner layer of the PET film layer is a performance layer, and the outer layer of the PET film layer is covered with a protection layer. According to the decoration strip, the PET film layer is arranged on the surface, the vacuum coating layer is located between the PET film layer and the base material layer, and therefore the problems of silver stripping, poor solvent resistance and scratches are solved; the PET film layer is relatively thick so that the appearance defects such as pores, orange peel-like surfaces and pits of the base material layer can be effectively avoided; the protection layer is independently subjected to high-temperature resisting and hardening treatment so that extrusion defects such as scratches and drawing stamps on the surface in the extrusion process can be prevented; and the decoration strip is formed through integral IMD process extrusion molding, and therefore the splicing joint phenomenon of repeated hot stamping between different planes of plastic parts is avoided, the appearance effect of the decoration strip is improved, and the market competitiveness of the product is further improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a decorative strip for a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common electrical appliance used for low-temperature preservation of food or other items in daily life. It is widely used in life and industry. At present, the surface decoration treatment of plastic decorative strips used in interior parts such as refrigerator glass shelves, fruit and vegetable boxes, transparent drawers and bottle frames mainly adopts electroplating, spraying, heat transfer printing and hot stamping and other technologies. The electroplating process has been gradually replaced by other processes due to its high cost and serious environmental pollution. The surface coating of the spray-treated decorative strip has poor solvent resistance and is easy to scratch. Now it is used less and les...

AI Technical Summary

Problems solved by technology

The electroplating process has been gradually replaced by other processes due to its high cost and serious environmental pollution. The surface coating of the spray-treated decorative strip has poor solvent resistance and is easy to scratch. Now it is used less and less.

The thermal transfer and hot stamping process is widely used on refrigerator decorative strips because of the variety of colors on the surface of the decorative strip, low cost and relatively simple technology. Defects such as obvious stitching seams
