Cementitious capillary crystalline waterproofing coating with high permeability as well as a preparation method of cementitious capillary crystalline waterproofing coating
The invention discloses a cementitious capillary crystalline waterproofing coating with high permeability. The cementitious capillary crystalline waterproofing coating comprises raw materials in percentage by weight as follows: 50%-55% of ordinary Portland cement, 15%-25% of quartz sand, 5%-10% of sodium-based nano-montmorillonite, 3%-8% of calcium pantothenate, 2%-6% of calcium citrate, 2%-4% of short glass fiber filaments, 1%-3% of organic phosphonate, 1%-3% of 2,3-dihydrobutanedioic acid, 1%-2% of a dimeric surfactant, 0.5%-1.5% of a complexing agent, 1%-3% of a coalescing agent and 0.1%-1% of a defoaming agent. The waterproofing coating has good weather fastness, high compressive strength, high breaking strength, good anti-permeability performance and good water resistance and is green and environment-friendly, when solidified coating meets water again, the coating can be activated secondarily, and crystals are generated again to block fine cracks of concrete. Besides, the waterproofing coating has good permeability, and coating bubbling and falling caused by the fact that moisture in the wall cannot be discharged are avoided.
