| 摘 要： | 研究了蓖麻油聚氨酯（ＰＵ）与聚醋酸乙烯酯（ＰＶＡｃ）在室温下生成的互穿网络聚合物（ＩＰＮ）。通过ＦＴ－ＩＲ和凝胶含量的测定，说明此种ＩＰＮ是接枝型ＩＰＮ。考察了该ＩＰＮ的各种组成对带锈铁板的附着力、柔韧性、冲击强度以及搭接剪切强度的影响。结果表明，当ＰＵ／ＰＶＡｃ＝５０／５０（ｗ／ｗ，质量比）时，ＩＰＮ的剪切强度最大，在此条件下合成的ＩＰＮ涂料是带锈铁板的良好涂料。

| Abstract: | The interpenetrating polymer networks(IPNS)obtained from castor oil polyurethane and Vinyl acetate monomer.The properties of this IPNS were Studied.Moreover,the sample of this graft IPN has been applied to coating when PU/PVAc is 50/50.The coating formed by PU/PVAc IPN on the iron plates without rust removal showed fairly good properties with respect to adhesion,impact strength,pliability and corrision resistivity. |
