ABS two-layer composite plate and preparation method thereof, liner and preparation method thereof as well as refrigeration equipment

Abstract

The invention provides an ABS two-layer composite plate which comprises a base material layer and a surface layer formed on the base material layer, wherein the surface layer contains an extrusion-grade ABS material; the base material layer contains an ABS special material and high glue powder; the number-average molecular weight of an acrylonitrile component in the ABS special material is greater than or equal to 180,000. The ABS two-layer composite plate provided by the invention has high gloss and is resistant to the corrosion of a foaming agent. The invention also provides a preparation method of the ABS two-layer composite plate, a liner using the ABS two-layer composite plate, a preparation method of the liner and refrigeration equipment using the liner.

Description

technical field

[0001] The invention relates to the technical field of refrigeration equipment, in particular to an ABS double-layer composite board and a preparation method thereof, an inner tank using the ABS double-layer composite board, a preparation method of the inner tank, and a refrigeration equipment using the inner tank. Background technique

[0002] With the upgrading of refrigerator foaming technology, the types of foaming agents are becoming more and more diverse, and the requirements for the corrosion resistance of refrigerator liner materials are getting higher and higher. One side of the refrigerator liner faces the interior of the refrigerator, which needs to meet the high-gloss aesthetic requirements; the other side is in direct contact with the foaming agent, which needs to meet the corrosion resistance requirements. At present, ABS (acrylonitrile-butadiene-styrene copolymer) resin is widely used as a refrigerator liner material, and it is not resistant to...
