Anti-aging polymer repair mortar and preparation method thereof
The invention discloses anti-aging polymer repair mortar and a preparation method thereof. The anti-aging polymer repair mortar is prepared from 10 to 20 parts of Portland cement, 20 to 40 parts of quartz sand, 2 to 4 parts of polyvinyl alcohol resin emulsion, 2 to 4 parts of polyurethane emulsion, 0.05 to 0.5 part of cross-linking agent, 1 to 2 parts of inorganic nano particle powder, 1 to 2 parts of graphite, 0.05 to 0.1 part of water reducing agent and 15 to 30 parts of water. An emulsion blending method is utilized, and PVA and PU are subjected to a cross-linking reaction through sufficient stirring to form an interpenetrating network structure. In the structure, the two polymers are interwoven and permeated with each other to form a stable network system. The PVA and the PU complement each other and have a synergistic effect while maintaining respective performance, so that the overall performance of the polymer repair mortar is improved.
本发明公开了一种耐老化的聚合物修补砂浆及其制备方法，包括硅酸盐水泥10～20份，石英砂20～40份，聚乙烯醇树脂乳液2～4份，聚氨酯乳液2～4份，交联剂0.05～0.5份，无机纳米粒子粉体1～2份，石墨1~2份，减水剂0.05～0.1份，水15～30份。本发明利用乳液共混法，通过充分搅拌使得PVA和PU交联反应形成互穿网络结构。在这种结构中，两种聚合物相互交织、渗透，形成稳定的网络体系。使得PVA和PU在保持各自性能的同时，相互补充、协同作用，从而提高聚合物修补砂浆的整体性能。
