Abstract

The invention discloses a polyurethane foaming method by combining and using carbon dioxide and organic amine. The method comprises the following step of mixing a polyurethane foaming composition witha polyisocyanate monomer and / or isocyanate-terminated prepolymer for foraming, wherein before mixing, carbon dioxide is added to the polyurethane foaming composition, or added into the polyisocyanatemonomer and / or isocyanate-terminated prepolymer, or simultaneously added into the polyurethane foaming composition and the polyisocyanate monomer and / or isocyanate-terminated prepolymer, and the carbon dioxide is gas carbon dioxide, liquid carbon dioxide, subcritical carbon dioxide and / or supercritical carbon dioxide.

Description

technical field [0001] The invention relates to a polyurethane foaming method using carbon dioxide and organic amine in combination. The method uses gaseous carbon dioxide, liquid carbon dioxide and / or supercritical carbon dioxide as a foaming agent, and belongs to the field of polyurethane foam materials. technical background [0002] As a new polymer material, polyurethane rigid foam is light in weight, high in strength and has extremely low thermal conductivity. Automobiles, refrigerators and freezers and other household appliances and other industries. The most important raw material in the production of rigid polyurethane foam is the blowing agent. At present, these blowing agents are chlorofluorocarbons except cyclopentane. Because of their damage to the ozone layer, governments of various countries have already signed the "Montreal Protocol" international convention to restrict, phase out, and ban the use of such products. Production and use, China is also a signato...
