| 摘 要： | 经过表面改性后超细氧化铁红颜料粉体的分散稳定性能及其它性能得到了大大的改善。接近国外同类产品。通过对样品进行红外光谱(IR)、差热热质量(DTA／TG)、表面ξ电位的测试研究。结果表明改性剂(聚丙烯酸盐)不仅与铁红粒子表面的羟基产生作用，而且还能与铁红粒子晶格中的Fe-O键作用。

| Abstract: | The dispersion and other properties of red iron oxide pigment could be greatly improved by surface modification. The surface modification mechanism of the modifier was studied by testing samples with IR, DTA/TG and zeta potential based on the research of surface modification processing with red iron oxide in this paper. The results showed that the modifier not only reacted with hydroxide on the surface of red iron oxide particles, but also with Fe-O bonds in crystal lattice. |
