摘要
用甲苯二异氰酸酯(TDI)与改性酚醛树脂合成聚氨酯预聚体,之后引入一定量的N,N-二甲基乙醇胺(DMEA),然后用冰醋酸中和成盐后乳化,得到阴极电泳漆泳透力提升助剂。按一定比例添加至阴极电泳涂料(CED)中可显著提高槽液的泳透力。
A prepolymer was prepared from toluene diisocyanate （TDI） and modified phe-nolic resin, and then incorporated with N, N-dimethyl ethanolaminc （DMEA） , further neu- tralized with glacial acetic acid, finally emulsified to form an additive for cathodic electrodepo- sition coatings. This additive can help enhance the throwing power of bath significantly.
