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

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; ...
