中文摘要：

论述了外墙涂层被污染的主要原因及污染的分类。在此基础上,对自洁涂料制备中所采用的憎水性自洁技术、仿生自洁技术、基于亲水性表面的耐沾污、涂膜微粉化技术、自分层技术、纳米光催化技术,及其在改善外墙涂料自清洁功能特性方面的应用进行了详细阐述。并从原材料和助剂选择以及涂料配方设计两方面,提出增强涂层抗污自洁的途径。

英文摘要：

The main reasons that exterior wall paint was polluted and pollution sorts were analyzed. Several technologies such as hydrophobic self-cleaning coating technology, biomimetic self-cleaning technology, micro-powder technology, self-stratifying technology, nano-photocatalysis technology, which could improve the self-cleaning performance of exterior wall coatings and their application were summarized in detail. At last, basing on two aspects, i.e. the selection of raw materials and additivies, and prescription design, respectively, the approach to improve the contamination resistance of coatings were summed up.
