    摘要: The present invention relates to the technical field of rigid polyurethane foams, and particularly to a rigid polyurethane foam prepared from the following raw materials in parts by weight through mixing and reaction: 135-165 parts of polyisocyanate, 100 parts of polyol composition, 10-16 parts of C-pentane, 1.8-2.3 parts of catalyst, 1.8-2.5 parts of silicone oil, 1.6-2.4 parts of water, and 1-chloro-3,3,3-trifluoropropene accounting for 1%-3% of the total weight of the raw materials. The present invention also relates to a preparation method of the rigid polyurethane foam and applications of the rigid polyurethane foam in the industries of refrigerators and ice lockers. The rigid polyurethane foam according to the present invention has smaller, finer and more uniform cells, so that the thermal conductivity (which can be as low as 0.01800 W/m.K or below) is greatly reduced and the strength of the foam is increased; in addition, the rigid polyurethane foam lowers energy consumption and is good in environmental friendliness; the rigid polyurethane foam according to the present invention has a positive role in promoting upgrading and updating of the existing C-pentane foaming technologies for refrigerators.

    摘要: Disclosed is a combination of hydrofluoroolefins and/or hydrochlorofluoroolefins with stabilizers wherein the stabilizers minimize the degradation of the hydrofluoroolefins and hydrochlorofluoroolefins during storage, handling and use yet allow for atmospheric degradation. The combinations exhibit low or zero ozone depletion potential and lower global warming potential making them of interest as replacements for chlorofluorocarbons and hydrfluorocarbons. The combinations of the present invention comprise hydrofluoroolefins and/or hydrochlorofluoroolefins in combination with a stabilizer or stabilizers selected from free radical scavengers, acid scavengers, oxygen scavengers, polymerization inhibitors and combinations thereof.
