Pasty micro cement and preparation method thereof
The invention relates to the field of building materials, and particularly discloses paste micro cement and a preparation method thereof. The paste micro cement is prepared from the following raw materials in parts by weight: 350 to 450 parts of waterproof emulsion, 80 to 140 parts of styrene-acrylic emulsion, 2 to 5 parts of dispersing agent, 70 to 120 parts of titanium dioxide, 160 to 240 parts of light calcium carbonate, 3 to 8 parts of hydroxypropyl methyl cellulose, 160 to 220 parts of ordinary Portland cement, 2 to 6 parts of sodium citrate and 0.4 to 1.2 parts of polyether modified organic silicon type defoaming agent. The pasty micro-cement prepared by the invention is free of pores and bubbles on the surface, and has relatively good compressive strength and breaking strength.
本申请涉及建筑材料领域，具体公开了一种膏状微水泥及其制备方法，所述膏状微水泥包括如下重量份的原料：防水乳液350‑450份、苯丙乳液80‑140份、分散剂2‑5份、钛白粉70‑120份、轻质碳酸钙160‑240份、羟丙基甲基纤维素3‑8份、普通硅酸盐水泥160‑220份、柠檬酸钠2‑6份、聚醚改性有机硅型消泡剂0.4‑1.2份；本申请制得的膏状微水泥表面无气孔气泡，具有较好的抗压强度和抗折强度。
