| 摘 要： | 以二异氰酸酯、聚醚210、二羟甲基丙酸为原料合成预聚物,再用1,4-丁二醇进行扩链,以正丁醇为封端剂进行封端,然后用三乙胺中和,最后加水乳化,制得了无污染的、便于使用的聚氨酯乳液,并就封闭型水性聚氨酯与未封闭水性聚氨酯的性能进行了比较。

STUDY ON PREPARATION OF SEALED POLYURETHANE EMULSION |
| |
| Abstract: | Firstly,the prepolymer based on toluene 2,4 diisocyanate(TDI),poly(propylene glycol)210(PPC210)and dimethylolpropionic acid(DMPA)were synthesized in the paper.After a chain extension reaction with 1,4 butanediol,the prepolymer was sealed by n butanol,following by a neutralization process with triethyamine(TEA).Finally,the system was dispersed into water.Then the nonpolluting polyurethane emulsion,an easily use one,was gained.And the characters of the sealed polyurethane were also compared with that of the no sealed one in the paper. |
