| titleOfInvention | Method for preparing polyurethane resin with high elongation at break |
| abstract | The invention relates to a method for preparing polyurethane resin with high elongation at break, comprising the following steps: (1) subjecting polymer polyol and diisocyanate with the chemical equivalent of 1.2 times to reaction, and stopping the reaction after the viscosity reaches 1.0*10<5>-3.0*10<5> mPa.s/25 DEG C to obtain a resin A; (2) subjecting a chain extender and diisocyanate with the chemical equivalent of 1.2 times to reaction, and stopping the reaction after the viscosity reaches 1.0*10<5>-3.0*10<5> mPa.s/25 DEG C to obtain a resin B; and (3) mixing the resin A with the resin B to obtain the final product, wherein the weight of the resin A accounts for 30-90%, and the weight of the resin B accounts for 10-70%. Due to the independent synthesizing of soft and hard segments and blending, the soft and hard segments are bound together only by strong hydrogen bonds, the phase transition zones of the soft and hard segments are eliminated to the maximum extent, the phase separation structure is improved, the restriction of the hard segments to the soft segments is reduced, and the characteristics of the soft segments are exerted. |
