摘要： 采用一种无机改性交联剂可以有效屏蔽聚乙烯醇(PVA)上部分羟基，改性后的 PVA与硅溶胶产生半互穿网络(Semi-IPN)连接，形成复合胶。所得的复合胶既有聚乙烯醇的优良成膜性，又有硅溶胶的耐水性和硬度，再加入优质廉价的颜填料，适当调节体系性能，便可生产出性价比高的环保水溶性建筑涂料。

Abstract: The use of an inorganic modified-cross could effectively shield off part of the hydroxyl group in polyvinyl alcohol( PVA), and the modified PVA and silicasol formed a semi-interpenetrating network(semi-IPN) connection, resulting a compound adhesive. The compound adhesive could provide good film forming ability of PVA, as well as the water resistance and film hardness of the siliconsol. Adding quality cheap pigments and fillers in the compound adhesive and properly adjusting system performance, a cost-effective, environmental friendly watersoluble architectural coatings could be formulated.
