Colored self-leveling dry-mixed mortar and preparation method thereof
The invention provides colored self-leveling dry-mixed mortar and a preparation method thereof, and belongs to the technical field of building materials. The colored self-leveling dry-mixed mortar disclosed by the invention is prepared from the following components in parts by weight: 15 to 20 parts of Portland cement, 10 to 16.5 parts of sulphoaluminate cement, 10 to 20.5 parts of steel slag, 5 to 8 parts of fly ash, 41.5 to 49.5 parts of coarse sand, 36.7 to 40.5 parts of fine sand, 1.5 to 3.5 parts of light-burned dolomite, 0.5 to 5.5 parts of high-molecular polymer hydroxypropyl methyl cellulose ether, 0.1 to 3.5 parts of redispersible latex powder, 0.5 to 1.0 part of water reducing agent, 0.1 to 0.4 part of defoaming agent and 1.5 to 3.5 parts of inorganic pigment. The colored self-leveling dry-mixed mortar obtained by the preparation method disclosed by the invention has better anti-cracking performance while meeting the requirements of mechanical properties, can be quickly coagulated after being smeared on a substrate, does not generate a bleeding phenomenon after being used for a long time, and is high in color persistence and not easy to sand.
本发明提供了一种彩色自流平干混砂浆及其制备方法，属于建筑材料技术领域。本发明中彩色自流平干混砂浆包含以下组分：硅酸盐水泥15～20份、硫铝酸盐水泥10～16.5份、钢渣10～20.5份、粉煤灰5～8份、粗砂41.5～49.5份、细砂36.7～40.5份、轻烧白云石1.5～3.5份、高分子聚合物羟丙基甲基纤维素醚0.5～5.5份、可再分散乳胶粉0.1～3.5份、减水剂0.5～1.0份、消泡剂0.1～0.4份、无机颜料1.5～3.5份。本发明得到彩色自流平干混砂浆在满足力学性能需要的同时，具备较好的抗开裂性能，砂浆涂抹到基底上之后能够快速凝结，长时间使用不会发生泌水现象、色彩持久度高，不易起砂。
