Backwater face impermeable cement-based capillary crystalline waterproof material and preparation process thereof
The invention discloses a downstream face impervious cement-based capillary crystalline waterproof material and a preparation process thereof, and relates to the technical field of waterproof materials. The downstream face impermeable cement-based capillary crystalline waterproof material prepared by the invention is prepared from the following components in parts by weight: 40-60 parts of cement, 30-40 parts of quartz sand, 15-25 parts of a flatting agent, 0.8-1 part of a defoaming agent, 0.5-2.5 parts of a water reducing agent, 3-8 parts of lime and 8-12 parts of gypsum. The cement is sulphoaluminate cement; the flatting agent adopts composite filler microspheres; the composite filler microspheres are prepared by the following steps: firstly, impregnating mesoporous silica in a 2, 4-toluene diisocyanate tripolymer, and then wrapping with poly (butyl acrylate), aluminum palmitate is adopted as the defoaming agent; melamine formaldehyde resin is adopted as the water reducing agent; the downstream face impermeable cement-based capillary crystalline waterproof material prepared by the invention has self-healing property and relatively strong waterproofness.
本发明公开了一种背水面抗渗水泥基渗透结晶型防水材料及其制备工艺，涉及防水材料技术领域。本发明制备的背水面抗渗水泥基渗透结晶型防水材料，按重量份数计包括以下组分：水泥40～60份、石英砂30～40份、流平剂15～25份、消泡剂0.8～1份、减水剂0.5～2.5份、石灰3～8份、石膏8～12份；所述水泥采用硫铝酸盐水泥；所述流平剂采用复合填料微球；所述复合填料微球是先将介孔二氧化硅浸渍在2,4‑甲苯二异氰酸酯三聚体中，随后采用聚丙烯酸丁酯进行包裹得到；所述消泡剂采用棕榈酸铝；所述减水剂采用三聚氰胺甲醛树脂；本发明制得的背水面抗渗水泥基渗透结晶型防水材料的具有自愈合性且防水性较强。
