Abstract

In making foamed polyurethane thermal insulation material, components capable of forming a polyurethane without evolution of carbon dioxide are employed, and the reaction to polyurethane is carried out in the presence of a liquid which vaporizes to give a gas inert to polyurethane and of thermal conductivity less than that of carbon dioxide. The liquid is exemplified by halogenated hydrocarbons of b.pt. in the range 40-140 DEG F., e.g. trichloromonofluoromethane and trichlorotrifluoroethane. The material may be formed between the inner and outer body panels of a refrigerator cabinet. An example is concerned with reacting a water-free polyester of hydroxyl No. 430 and acid number 1.5 with toluene diisocyanate, mixing the product with ethylene glycol, dimethyl ethanolamine, polyoxyethylene sorbitan monopalmitate as emulsifier and liquid trichloromonofluoromethane, and allowing attainment of a temperature of 250 DEG F. A comparative example describes the production of a carbon dioxide-filled foam. Foams may also be made from reaction products of polyisocyanates with castor oil, glycols, diamines, polyesteramides and polyalkylene glycol ethers.ALSO:In making foamed polyurethane thermal insulation material, components capable of forming a polyurethane without evolution of carbon dioxide are employed, and the reaction to polyurethane is carried out in the presence of a liquid which vaporizes to give a gas inert to polyurethane and of thermal conductivity less than p that of carbon dioxide.
