Abstract

The invention discloses a polyol polyurethane foam, which was characterized by raw material composition and weight ratios as follows: 21.6-41.6 percent in vegetable oil, the catalyst of 3.2-3.6 percent, 11.2-27.2 percent in flame retardants, acetone 30.8 -54.8 percent , 2.8-3.2 percent in the water, GWP is a zero ODP, non-toxic, non-pollution for the environment, without damages to the ozone layer, and can not change the existing production equipment and production techniques, low price of polyol - urethane foam.

Description

Technical field: [0001] The invention relates to the technical field of foaming agents, in particular to a polyol polyurethane foaming agent, which is mainly used for the insulation layer of refrigeration. Background technique: [0002] The synthesis of polyurethane polymers used in the insulation layer of traditional refrigeration equipment must use Freon and Freon series compounds as foaming agents. ODP (Ozone Depletion Potential) and GWP (Greenhouse Effect) are produced during the polymerization process, which will damage the earth. Atmospheric ozone protective layer leads to bad ecological changes and endangers human health; when the international decree prohibits the use of freon and freon series compounds, people began to look for polyurethane foaming agents that can replace freon CFC11 and zero ODP, and 141B made in the United States appeared. The various alternative blowing agents represented by chlorofluorocarbons have not been able to break away from the Freon seri...
