Abstract

Disclosed in the present invention are an environmentally-friendly and energy-saving structural layer for a refrigeration device, and applications thereof. The structural layer consists of an HFO foamable rigid polyurethane foam layer and a modified aromatic vinyl resin interior lining board. The modified aromatic vinyl resin is an organosilicon polymer. In the modified aromatic vinyl resin, the weight content of the organosilicon polymer accounts for 20% to 95%. The environmentally-friendly and energy-saving structural layer for a refrigeration device preparedin the present invention overcomes the problem of material cracking of an existing refrigeration device when the HFO foaming agent and the ABS interior lining board are used together, improving environmentally-friendly and energy-saving performance of the refrigeration device, and maintains good forming performance because the structural layer still contains the ABS material, so that variability and high-end tastes can be implemented on the structural design of the refrigeration device.

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...
