Beschreibung
Zusammenfassung:	The invention discloses a polyurethane thermal-insulation material which is composed of 1 part by weight of component A and 1.5-2 parts by weight of component B, wherein the component A is composed of polyether 835, polyether 310, polyether 403, polyether 4110, a catalyst and silicone oil; and the component B is isocyanate. When the material is in construction, the mixture is sprayed on the working surface through compressed air by a spraying plant, and then is solidified. The material has the advantages of low construction environment requirements and excellent properties.
