| titleOfInvention | Conjugate polyethers, polyisocyanurate continuous sheets derived therefrom, and methods of making same |
| abstract | The invention relates to a combined polyether, a preparation method thereof and a preparation method of a Polyisocyanurate (PIR) continuous plate. The composite polyether comprises the following components in parts by weight: 70-90 parts of polyester polyol, 10-30 parts of polyether polyol, 2-3 parts of foam stabilizer, 1.5-3 parts of catalyst, 23-35 parts of flame retardant, 0.5-1 part of water and 15-31 parts of physical foaming agent. Wherein the polyester polyol has a functionality of 2, a hydroxyl value of 170 to 240mgKOH/g, and a viscosity of 9000 to 13000mPa · s at 25 ℃; a polyether polyol having a hydroxyl value of 200 to 235mgKOH/g and a viscosity of 80000 to 120000 mPas at 25 ℃. The sum of the mass parts of the polyol and the polyether polyol is 100 parts. The physical foaming agent comprises 10-16 parts of cyclopentane. The polyisocyanurate foamed plastic product prepared from the combined polyether has excellent compression strength, dimensional stability and oxygen index, is safe and environment-friendly, and has an Ozone Depletion Potential (ODP) of 0. |
