水性含磷聚合物在涂料中的应用研究进展

水性含磷聚合物具有良好的热稳定性、耐腐蚀性等优点，是一种重要的环境友好型材料。本文主要介绍了水性含磷丙烯酸类和聚氨酯类等重要的水性含磷聚合物，并对这两种聚合物的合成及其在水性防火涂料和防腐涂料中的应用进行了讨论。分析结果表明：以水性含磷聚合物为基料的防火涂料热稳定性较好，成炭率明显增加，阻燃性能大大提高；以水性含磷聚合物为基料的防腐涂料，漆膜附着力增强，防腐性能提高。提出今后的研究方向是：①将磷与卤素、氮、硅等元素同时引入水性聚合物中，以协同阻燃；②将含磷基团引入聚合物分子内，作为基料来提高阻燃性能。

Research progress in water-borne phosphorus-containing polymer in coatings

The water-borne phosphorous-containing polymers are important environmental- friendly materials with excellent flame-proofing，corrosion resistance properties. Two kinds of water-borne phosphorous-containing polymers，acrylate polymer and polyurethane，are introduced，and their synthesis and applications in water-borne fire-retardant coatings and corrosion-resistant coatings are also discussed in this paper. Research shows that phosphorous-containing polymers can improve the thermal degradation，residual char and flame retardant of water-borne fire-retardant coatings as well as enhance the corrosion resistance and adhesion of water corrosion-resistant coatings. The paper proposes two issues in the future as follows：①by making use of synergistic effect，water-borne polymers which contain several flame proofing elements such as halogen，nitrogen，silicon，phosphorus simultaneously can be studied；②phosphorus-containing monomers units may be incorporated into polymer structure to improve the fire-retardant property.
