thermo-negative reaction

Siloxane modified polyurethane ( PU) prepolymer was prepared by reaction between poly ( dimethylsilone) oligomers with terminal amine group and PU prepolymer, then isocyanate group was blocked with sodium bisulfite ( NaHSO 3) and thermo-reactive water-based polyurethane was obtained by dispersion method in water.

用氨丙基聚硅氧烷与PU预聚体反应生成含硅氧烷的PU预聚体，通过NaHSO3封闭NCO基，并在水中分散制得有机硅改性热反应型水基聚氨酯乳液。
