Abstract

The invention discloses an HIPS (High Impact Polystyrene) double-layer composite board for a liner of a refrigerating device and a preparation method of the HIPS double-layer composite board. The HIPS double-layer composite board for the liner of the refrigerating device comprises a surface layer and a bottom layer, wherein the surface layer is composed of a surface layer HIPS; the surface layer HIPS is selected from one or more of a natural-color HIPS, a dyeing HIPS and a modified extruded-grade HIPS; and the bottom layer comprises a natural-color extruded-grade HIPS and a recirculation scrap.. According to the HIPS double-layer composite board for the liner of the refrigerating device disclosed by the embodiment of the invention, the surface layer and the bottom layer are made of HIPS materials and all the sieved HIPS materials have good compatibility, so that the HIPS materials can be mutually mixed and the appearance and the machining performance of the board can not be obviously influenced; and therefore, the board strength can be improved and the cracking risk is reduced.

Description

technical field

[0001] The invention relates to the technical field of refrigeration equipment manufacturing, more specifically, the invention relates to a HIPS two-layer composite board for the inner tank of a refrigeration equipment and a preparation method thereof. Background technique

[0002] The high-gloss HIPS composite panels for refrigerators / freezers in the prior art all adopt a two-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 e...
