Abstract

The possibility of using organomineral complexes of polyhexamethylene guanidine hydrochloride as a functional additive for a waterborne paint based on polyvinyl acetate has been investigated. Organomineral complexes containing 20 and 30 wt % guanidine polymer have been obtained, with intercalation of polyguanidine chains into the interlayer space of montmorillonite being observed. It has been revealed that the stability of the polymer film to water is retained when organomineral complexes are introduced into a polyvinyl acetate dispersion, whereas the water resistance of the film sharply decreases when free polyguanidine is added. There was no significant influence of organomineral complexes on the rheological characteristics of the dispersion and its sedimentation stability. Testing of waterborne paints with various additives has shown that introduction of organomineral complexes into the material prevents the coating from fouling by biofilms of gram-positive bacteria Staphylococcus aureus and Rhodococcus erythropolis, with the hardness, water resistance, and water-vapor transmission of the coatings being retained at a satisfactory level.

含胍有机配合物作为水性高分子材料杀生功能添加剂的应用前景

摘要研究了以聚己亚甲基胍盐酸盐有机配合物作为聚醋酸乙烯基水性涂料功能添加剂的可能性。在蒙脱土的层间空间中发现了多胍链插入现象，得到了含有20%和30%胍聚合物的有机矿物配合物。研究表明，将有机配合物引入聚醋酸乙烯分散体时，聚合物膜对水的稳定性保持不变，而当加入游离聚胍时，膜的耐水性急剧下降。有机配合物对分散体的流变性能和沉降稳定性没有显著影响。对各种添加剂的水性涂料的测试表明，在材料中引入有机复合物可以防止涂料被革兰氏阳性细菌金黄色葡萄球菌和红红红球菌的生物膜污染，使涂料的硬度、耐水性和水蒸气透射率保持在令人满意的水平。
