Abstract

The invention discloses a refrigeration equipment environmental-friendly energy-saving structural layer and application thereof. The structural layer consists of an HFO (Heavy Fuel Oil) foamed rigid polyurethane foamed layer and a modified aromatic vinylite lining plate, wherein modified aromatic vinylite is a vinyl cyanide-aromatic ethylene-unsaturated olefine acid ester polymer; in the modified aromatic vinylite, the weight content of the vinyl cyanide-aromatic ethylene-unsaturated olefine acid ester polymer is 20-95%. By adopting the refrigeration equipment environmental-friendly energy-saving structural layer disclosed by the invention, the problem that material cracking can be caused if an HFO foaming agent and an ABS (Acrylonitrile Butadiene Styrene) lining plate are used in cooperation in conventional refrigeration equipment is avoided, the environmental-friendly and energy-saving properties of the refrigeration equipment are improved, and meanwhile as the structural layer still has an ABS material, good molding performance is maintained, and diversity and high-end taste orientation of structural design of refrigeration equipment are achieved.

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...
