摘　　要：聚脲涂料是当前世界范围内综合性能最佳的有机高分子材料之一,常用于多领域防水,尤其是篮球场场地建设层面防水。为改善球场场地用聚脲防水涂料防水应用效果,以附着力优异的环氧树脂为底漆设计制备了聚脲防水涂料,并对其涂层防水性能进行了测试表征。结果发现,聚脲防水涂料涂层可提高混凝土试样抗渗性,延长混凝土结构使用寿命;聚脲防水涂料防水涂层物化、耐久性能皆满足国家现行标准基本要求;聚脲防水涂料喷涂涂层的水泥砂浆试样抗冻性良好,抗冻等级较高;随着磨损时间延长,聚脲防水涂料涂层摩擦系数先增加后趋向于稳定,磨损质量损失则随之增大。球场用聚脲防水涂料涂层防水性能良好,防水应用效果较好。Polyurea coating is one of the organic polymer materials with the best comprehensive performance worldwide,commonly used for waterproofing in various fields,especially in the construction of sports stadiums and venues.In order to improve the waterproof application effect of polyurea coatings for sports venues,the polyurea waterproof coating was designed and prepared with epoxy resin with excellent adhesion as the primer,and the waterproof performance of the coating was tested and characterized.The results showed that epoxy resin polyurea coating effectively improved the impermeability of concrete samples and extended the service life of concrete structure.The physicochemical and durability properties of the epoxy resin polyurea waterproof coating met the basic requirements of the current national standards.The cement mortar sample sprayed with epoxy resin polyurea coating had good frost resistance and a high frost resistance level.With the extension of wear time,the friction coefficient of the epoxy resin polyurea coating first increased and then tend to stabilize,resulting in an increase in wear quality loss.In short,the polyurea waterproof coating for the stadium has good waterproof performance and good waterproof application effect.
