| titleOfInvention | A kind of low-conductivity foaming agent composition, rigid polyurethane foam and preparation method thereof |
| abstract | The invention discloses a low-conductivity foaming agent composition and a rigid polyurethane foam prepared therefrom. The foamed plastic is made of the following raw materials through a high-pressure foaming machine according to parts by weight: combined polyether: foaming agent composition: polyisocyanate 100: 15-28: 130-160, combined polyether is composed of the following components by weight: poly ether composition: surfactant: composite catalyst: water = 90-100: 1.5-4.0: 1.5-4.0: 1-3, the foaming agent composition is composed of the following components according to weight fraction: pentane: 1-chloro- 3,3,3 Trifluoropropene (LBA): 1,1,1,2,2,3-Hexafluoropropane (HFC-236cb): Perfluoro(3-methyl-2-pentene) (PF-90 )=5～12:1～10:1～10:1～5. The polyurethane foam prepared by the foaming agent composition has the characteristics of low density, low thermal conductivity and high dimensional stability. |
