| titleOfInvention | Combined polyether and polyurethane for super-large solar water heater water tank and preparation method thereof |
| abstract | The application relates to composite polyether and polyurethane for an oversized solar water heater water tank and a preparation method thereof, wherein the foaming pressure is lower than 4000Pa, the problems of explosion and incomplete filling of the water tank cannot be caused when the oversized water tank is produced, and one-gun material injection is realized. The composite polyether for the super-large solar water heater water tank comprises the following components in parts by weight: 70-90 parts of a polyether polyol component, 10-30 parts of a polyester polyol component, 2-3 parts of a catalyst, 2-3 parts of a foam stabilizer, 20-25 parts of a foaming agent and 0.8-1.5 parts of water, wherein the polyether polyol component is composed of at least two polyether polyols, the polyether polyol satisfies the hydroxyl value of 310-400 mgKOH/g, the viscosity at 25 ℃ is 1100-12500 mPa.s, the water content is less than 0.20%, the polyester polyol is at least one of a polyester polyol based on di-phthalic anhydride and a polyester polyol based on phthalic anhydride, the polyester polyol satisfies the hydroxyl value of 300-330 mgKOH/g, the viscosity at 25 ℃ is not more than 2000-3000 mPa.s, the water content is not more than 0.15%, and the foam stabilizer is silicone oil. |
