Expansion joint filling material and preparation method thereof
The invention discloses an expansion joint filling material and a preparation method thereof.The expansion joint filling material comprises a caulking material and a waterproof protection material, and the waterproof protection material is sprayed to the top of the caulking material; the caulking material comprises the following components in parts by mass: 100 parts of cement and 4-8 parts of short steel fibers coated with polyurethane rubber, the waterproof protection material comprises a component A and a component B. The component A comprises, by mass, 40-60 parts of modified emulsified asphalt and 30-50 parts of rubber emulsion, and the component B is a flocculating agent. The preparation method of the expansion joint filling material comprises the following steps: uniformly mixing and stirring cement and short steel fibers coated with polyurethane rubber to obtain a caulking material; and uniformly mixing the modified emulsified asphalt and the rubber emulsion to prepare a component A, and preparing a flocculating agent to prepare a component B, namely the waterproof protection material. The expansion joint filling material has good water resistance and temperature adaptability, and the preparation method is simple in process.
本发明公开了伸缩缝填充材料及其制备方法，所述伸缩缝填充材料包括嵌缝材料和防水保护材料，其中，所述防水保护材料喷涂在所述嵌缝材料的顶部；所述嵌缝材料按质量份计含有：水泥100份，外包覆有聚氨酯橡胶的短钢纤维4～8份；所述防水保护材料含有A组分和B组分，所述A组分按质量份计包括：改性乳化沥青40～60份，橡胶乳液30～50份，所述B组分为絮凝剂。所述伸缩缝填充材料的制备方法为将水泥与外包覆有聚氨酯橡胶的短钢纤维混合搅拌均匀，制得嵌缝材料；将改性乳化沥青与橡胶乳液混合均匀制得A组分，配置絮凝剂制得组分B即得防水保护材料。本发明所述伸缩缝填充材料具有良好的防水及温度适应性，所述制备方法工艺简单。
