Problems solved by technology

At present, ABS (acrylonitrile-butadiene-styrene copolymer) resin is widely used as a refrigerator liner material, and it is not resistant to the mixed blowing agent HFC-245fa (1,1,1,3,3-pentafluoro propane) and LBA (1-chloro, 3,3,3-trifluoropropene), resulting in a higher risk of cracking of the refrigerator liner

preparation example Construction

[0041] The present invention also proposes a preparation method of the ABS double-layer composite board, the preparation method comprising the following steps:

[0042] The mixture is prepared by mixing special ABS material with high-grade rubber powder, wherein the number average molecular weight of the acrylonitrile component in the special ABS material is greater than or equal to 180,000;

[0043] Extrusion-grade ABS material is provided, and the mixture and extrusion-grade ABS material are subjected to double-layer co-extrusion treatment to obtain the ABS double-layer composite sheet. The ABS double-layer composite sheet includes a substrate layer and a substrate layer formed on the substrate. The surface layer on the surface of the layer contains extrusion-grade ABS material, and the substrate layer contains ABS special material and high rubber powder.

[0044]Further, pigments and auxiliary agents are added to the above mixture; before the double-layer co-extrusion treat...

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...
