| titleOfInvention | A kind of silicon-modified long-chain carboxyl polyether-carbonate waterborne polyurethane and preparation method thereof |
| abstract | The invention discloses a method for preparing silicon-modified long-chain carboxyl polyether-carbonate water-based polyurethane, which comprises: taking epoxy compound, epoxy monomer containing double bonds, and carbon dioxide as monomers to obtain long-chain bis bond-based polyether-carbonate polyol, and then click chemistry with mercapto carboxylic acid monomers to obtain long-chain carboxy-type polyether-carbonate polyol; long-chain carboxy-type polyether-carbonate polyol, two Isocyanate is mixed with polyhydroxy chain extender, and the water-based polyurethane prepolymer is prepared by reaction, and then modified by aminosilane coupling agent and chain extended with water to obtain silicon-modified long-chain carboxyl polyether-carbonate water-based polyurethane . The silicon-modified long-chain carboxyl polyether-carbonate waterborne polyurethane has high emulsification efficiency and excellent emulsion stability; it also has excellent mechanical properties, heat resistance and hydrophobicity. |
