Additive for improving mortar strength and waterproof performance and preparation process thereof
The invention belongs to the technical field of mortar additives, and particularly relates to an additive for improving mortar strength and waterproof performance and a preparation process thereof. The composite material is prepared from the following components in parts by weight: 5 to 10 parts of polytetrafluoroethylene, 10 to 20 parts of quartz powder, 5 to 10 parts of silicon carbide, 5 to 10 parts of graphene, 5 to 8 parts of epoxy resin curing agent, 5 to 8 parts of high silica glass fiber, 1 to 5 parts of polyvinyl alcohol fiber, 2 to 5 parts of polypropylene fiber, 1 to 1.5 parts of sodium stearate, 5 to 10 parts of epoxy emulsion, 3 to 5 parts of redispersible latex powder, 0.2 to 0.5 part of zinc borate, 0.1 to 0.2 part of water reducing agent and 0.5 to 1 part of hydroxypropyl methyl cellulose. And 0.2 to 0.5 part of a defoaming agent. When the additive is added into the mortar, the mortar can be effectively prevented from cracking, so that the obtained mortar has excellent water resistance, compressive strength and breaking strength, and the comprehensive mechanical properties of the mortar are remarkably improved.
本发明属于砂浆添加剂技术领域，具体涉及一种提升砂浆强度及其防水性能的添加剂及其制备工艺。由下列重量份数的成分组成：聚四氟乙烯为5～10份，石英粉10～20份，碳化硅5～10份，石墨烯5～10份，环氧树脂固化剂5～8份，高硅氧玻璃纤维5～8份，聚乙烯醇纤维1～5份，聚丙烯纤维2～5份，硬脂酸钠1～1.5份，环氧乳液为5～10份，可再分散性乳胶粉3～5份，硼酸锌0.2‑0.5份，减水剂0.1～0.2份，羟丙基甲基纤维素0.5～1份，消泡剂0.2～0.5份。本发明的添加剂添加到砂浆中可以有效防止砂浆开裂，使得到的砂浆具有优异的防水性、抗压强度和抗折强度，显著改善了砂浆的综合力学性能。
