The crosslinking reaction between the keto group and the hydrazine group was used to prepare the crosslinkable polyurethane/acrylic emulsion.
实验结果表明 ,水性聚氨酯中加入肼基化合物提高了膜的拉伸强度 ,硬度及耐水性等性能 ,同时发现 ,肼基化合物的用量在不超过 4 %时水性聚氨酯乳液最稳定 ;酰胺化合物的用量对苯丙乳液也有较大影响 ,酰胺化合物在乳液中质量分数小于 6 %时 ,丙烯酸乳液的稳定性最好。
The Crosslinkable polyurethane/styrene-acrylic polymer composite emulsion was obtained by mixing the styrene-acrylic polymer emulsion incorporating DAAM with the polyurethane dispersion containing hydrazine group.
将双丙酮丙烯酰胺 (DAAM)参与共聚的苯丙乳液与含有肼基的聚氨酯水分散体混合后 ,得到了交联型聚氨酯 /苯丙树脂复合乳液。
