由聚醚，甲苯二异氰酸酯（TDI），二羟甲基丙酸（DMPA）等为原料制备水性聚氨酯乳液胶粘剂．研究了DMPA用量的改变及在DMPA用量不变的情况下，R值（即n（NCO）/n（OH）值）的改变对乳液性能的影响．结果表明，R值的改变对胶膜的吸水率、力学性能、热稳定性等均产生重要的影响．

Aqueous polyurethane emulsion adhesive was prepared from polyether toluene diisocynate（TDI） and dimethylol propionic acid（DMPA）. The effects of DMPA dosage and the variation of R value（n（NCO）/n（OH）） at a fixed DMPA dosage on the properties of emulsion were determined．Results show that the variation of DMPA dosage and R value has great effects on hygroscopicity, mechanic and thermal properties of emulsion-cast film.
