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 end cover, wherein modified aromatic vinylite is a molten commixture of an ethylene-propylene-diene monomer toughened vinyl cyanide-aromatic ethylene polymer and acrylonitrile-butadiene-styrene; in the modified aromatic vinylite, the weight content of the ethylene-propylene-diene monomer toughened vinyl cyanide-aromatic ethylene 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) end cover are used in match 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 and glossiness are 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] Refrigeration equipment generally uses rigid polyurethane foam as the insulation layer, and rigid polyurethane foam currently generally uses cyclopentane (CP), hydrofluoroalkanes (HCFC, HFC) and hydrofluoroolefins (HFO) as blowing agents. Since the fourth-generation blowing agent hydrofluoroolefin HFO has low greenhouse effect potential (GWP) and zero ozone depletion potential (ODP), the heat insulation layer using HFO blowing agent can improve the insulation performance of refrigeration equipment, effectively Reduce the energy consumption level of refrigeration equipment, so energy-saving and environmentally friendly HFO will gradually replace the previous blowing agents such as hydrofluorochlorocarbons (CP, HCF...
