Inner container of refrigeration equipment and preparation method thereof

Abstract

The invention discloses an inner container of refrigeration equipment and a preparation method thereof. The inner container of the refrigeration equipment is formed by an HIPS (high impact polystyrene) three-layer composite board, the HIPS three-layer composite board comprises a surface layer, a basic layer and a bottom layer, wherein the surface layer is composed of a surface layer HIPS, and the surface layer HIPS is selected from one or more types of natural color HIPS, tinction HIPS and modification extrusion grade HIPS; and the basic layer comprises the natural color extrusion grade HIPS and a feeding material, and the bottom layer is composed of a resistance foaming agent erosion HIPS. According to the inner container of the refrigeration equipment provided by the embodiment of the invention, the HIPS three-layer composite board is adopted to shape, and the surface layer, the basic layer and the bottom layer of the HIPS three-layer composite board are all made of HIPS materials; the different HIPS materials after screening have good consistency, and can be mutually mixed; and the appearance and processing behaviour of the board can not be obviously influenced, the intensity of the board is improved, and the cracking risk is reduced.

Description

technical field [0001] The invention relates to the technical field of preparation of household appliances, and more specifically, the invention relates to an inner container of a refrigeration device and a preparation method thereof. Background technique [0002] The high-gloss HIPS composite panels for refrigerators / freezers in the prior art all adopt a three-layer composite system, and the surface layer is high-gloss HIPS. The bottom layer is HIPS for ordinary extrusion grade refrigerators. This board has the following disadvantages: [0003] 1. The high-gloss surface layer has low strength, brittleness, and no corrosion resistance. The resulting lining, especially the box lining, is easy to crack, and there are quality risks; [0004] 2. In order to reduce the possibility of cracking, the thickness of the surface layer is usually less than 3%, and the mold is also affected. The gloss of the obtained box lining is actually very low, and even the gloss cannot be seen; ...

AI Technical Summary

Problems solved by technology

[0003] 1. The high-gloss surface layer has low strength, brittleness, and no corrosion resistance. The resulting lining, especially the box lining, is easy to crack, and there are quality risks;

[0004] 2. In order to reduce the possibility of cracking, the thickness of the surface layer is usually less than 3%, and the mold is also affected. The gloss of the obtained box lining is actually very low, and even the gloss cannot be seen;

[0005] 3. The thickness of the extruded board surface layer is not easy to control, and the qualified rate of extruded board and blister is low;

[0008] 1. Different grades of ABS special materials provided by different suppliers have differences in color and performance;

[0009] 2. There are compatibility problems between different ABS special materials, and they cannot be mixed, which causes inconvenience to production management;

[0010] 3. At present, only a few companies can produce this kind of ABS special material, all rely on imports, the purchase cycle is long, and the price is high
