Abstract

An environmentally friendly energy-saving structural layer for a refrigeration device, and an application thereof. The present structural layer is composed of an HFO foaming rigid polyurethane foam layer and a modified aromatic vinyl resin lining plate material, the modified aromatic vinyl resin being a vinyl cyanide-aromatic vinyl-unsaturated and acrylate polymer; the content by weight of the vinyl cyanide-aromatic vinyl-unsaturated and acrylate polymer in the modified aromatic vinyl resin is 20-95%. The environmentally friendly energy-saving structural layer for a refrigeration device prepared by the present invention overcomes the problem in existing refrigeration devices of the material cracking when using an HFO foaming agent with an ABS lining plate material, and improves the environmentally friendly and energy-saving performance of the refrigeration device. ABS material is still contained in same, ensuring good mouldability, such that the structural design of the refrigeration device can be diverse and high-end.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment manufacturing, in particular, the invention relates to an environment-friendly and energy-saving structural layer of refrigeration equipment. Background technique [0002] Rigid polyurethane foam is generally used as a thermal insulation layer between the outer shell and inner lining of refrigeration equipment, and cyclopentane (CP), hydrofluoroalkane (HCFC, HFC) and hydrofluoroolefin (HFO) are generally used as rigid polyurethane foam at present. Blowing agent, among which the fourth generation blowing agent hydrofluoroolefin HFO has low greenhouse effect potential (GWP) and zero ozone depletion potential (ODP), and the heat insulation layer using HFO blowing agent can improve refrigeration The thermal insulation performance of equipment can effectively reduce the energy consumption level of refrigeration equipment. Therefore, HFO, which is energy-saving and environmentally friend...
