AI Technical Summary

Problems solved by technology

However, the process is complicated, the thickness of each layer is difficult to control, and the production cost is high.
At the same time, since HIPS is a non-polar material, and the polyurethane foam insulation layer is a polar material, the surface corona process is currently required to ensure the bonding ability of the two, which increases the difficulty of the production process

Abstract

The invention relates to a plate material for an inner container of a refrigerator and a preparation method thereof. The plate material for the inner container of the refrigerator is prepared from the following components in parts by weight: 100 parts of polyester material, 0.1 to 5 parts of titanium dioxide, 0.05 to 2 parts of lubricant, and 0.05 to 2 parts of antioxidant. The plate material has the advantages that the luster degree is higher, the multi-component foaming agent corrosion-resistant property is excellent, and the food safety is higher; because the plate material is the polyester material which belongs to the polarity material, the good adhering ability between the inner container of the refrigerator and the polyurethane foaming layer is good, the corona technology is not needed, and the difficulty in production technology is decreased.

Description

technical field [0001] The invention relates to a refrigerator liner, in particular to a plate for a refrigerator liner and a preparation method thereof. Background technique [0002] Most of the existing refrigerators use plate-grade HIPS or ABS, and the inner liner of the refrigerator is formed by extruding boards and blisters. However, ABS has been gradually replaced by plate-grade HIPS due to its high cost and inability to meet food safety requirements. In order to achieve the characteristics of high toughness, plate grade HIPS adds large particle size rubber during the polymerization process, so its surface has a matte effect, and the appearance cannot meet the requirements. At present, a layer of HIPS with a high-gloss effect is usually laminated on the surface of the matte layer by a multi-layer co-extrusion method, but the surface of the high-gloss HIPS has poor chemical corrosion resistance and is prone to cracks. When the inner liner of the refrigerator is in con...
