Problems solved by technology

Although HCFC-141b is now used to replace CFC-11, the atmospheric ozone layer dissipation index has been reduced, and it is not the final solution; now Europe also uses cyclopentane as a fluorine-free blowing agent, but the polyurethane produced by it is easy to produce. burn

Abstract

The invention relates to green environment-friendly polyurethane insulation material which will not destroy the atmospheric ozone layer. The insulation material is made from the raw materials with the following weight proportions and through the following method: (1) 92-96% of polyether, 0.5-2% silicone oil, 0.5-2% foam stabilizer, 1-4% catalyst and 1-4% of additive are fully mixed through a reactor to obtain the mixed material A; (2) according to the weight ratio of 1:0.05-0.3 between the mixed material A and HFC-245fa, the raw materials are evenly mixed to prepare the mixed material B; (3) based on the weight ratio of 1-1.1:1 between isocyanate and the mixed material B, the raw materials are mixed and foamed under high pressure so as to obtain the polyurethane solar energy insulation material after high-temperature solidification. The insulation material is green environment-friendly material which will not destroy the atmospheric ozone layer and has insulation and fire-retardant effects.

Description

technical field [0001] The invention relates to a solar thermal insulation material, in particular to a green and environment-friendly polyurethane thermal insulation material which does not destroy the atmospheric ozone layer. Background technique [0002] At present, polyurethane is used as a solar thermal insulation material, and its production volume is increasing. Generally, the combination polyether of polyurethane for solar energy is a mixture mixed with a physical foaming agent. The foaming agent is easy to volatilize in the combination polyether; and the foaming is all fluorine-containing foaming agent. The ozone layer has a dissipative effect. Although HCFC-141b is now used to replace CFC-11, the atmospheric ozone layer dissipation index has been reduced, and it is not the final solution; now Europe also uses cyclopentane as a fluorine-free blowing agent, but the polyurethane produced by it is easy to produce. burn. Contents of the invention [0003] In order ...
