| 中文摘要: |
| 利用磨细矿粉与水玻璃的碱激发反应，使用高弹性苯乙烯-丙烯酸酯共聚物乳液作为原材料制备了一种新型防水涂料，主要对比分析3种共聚物乳液对防水涂料力学性能的影响，并从反应过程、矿物组成、微观结构等方面探究影响其力学性能的内在原因．研究结果表明：BATF RS-300S乳液更适用于该新型防水涂膜，且具有优异的力学性能．这是由于其反应程度最大，生成更多的C-S-H凝胶．C-S-H凝胶、方解石及羧酸钙的生成为防水涂料提供主要强度，乳液为防水涂料提供柔性．该防水涂料力学性能优良，弥补了现有刚性防水涂料延展性不良的问题和柔性防水涂料施工工艺等方面的不足，并由于使用矿粉替代水泥作为原材料，生产过程绿色环保，具有良好的应用前景． |
| 英文摘要: |
| A novel waterproof coating is produced by using the alkali-activated reaction of grinding fine ores and waterglass with the high-elastic styrene-acrylate copolymer emulsion as raw material. The effect of three types of copolymer emulsions on the mechanical properties of waterproof coatings is investigated to explore the mechanism of strength development of the waterproof coatings from the reaction process, mineral composition and microstructure. Research results show that the BATF RS-300S emulsion is a better material for the novel waterproof coating because of its favorable mechanical properties, which is attributed to the high degree of reaction that produces more content of C-S-H gel. C-S-H gel, calcite and calcium carboxylate enhance the strength of this new waterproof coating, and emulsions enhance the flexibility of coatings. This waterproof coating is of good application prospects, because it shows favorable mechanical properties, overcomes the shortage of the existing poor ductility of rigid waterproof coating and construction technologies limits of flexible waterproof coating, then shows a better environmental benefit as no cement is used for the coating. |
