High-performance polymer mortar and preparation method thereof
The invention discloses high-performance polymer mortar and a preparation method thereof, and relates to the technical field of building materials, and the high-performance polymer mortar comprises the following raw materials by mass: 30-50 parts of special cement; 40-60 parts by mass of sand; 3-10 parts by mass of microbeads; 0.1 to 0.5 part by mass of a high-performance water reducing agent; 0.05 to 0.2 part by mass of a defoaming agent; 0-0.15 part by mass of an early strength agent; 0 to 0.2 part by mass of a retarder; 0.05 to 0.5 part by mass of a stabilizer; 0.1 to 0.5 part by mass of an expanding agent; 3-15 parts by mass of a polymer emulsion; 12 to 20 parts by mass of water; wherein the special cement is one or two of sulphoaluminate cement and high-alumina cement, and the sand is one or two of machine-made sand and river sand; the polymer emulsion is one or more of pure acrylic emulsion, styrene-acrylic emulsion and styrene-butadiene emulsion. The technical problems that existing polymer mortar is generally low in early strength, layered and segregated under high fluidity, large in mortar volume weight and prone to shrinkage are effectively solved.
本发明公开了一种高性能聚合物砂浆及其制备方法，涉及建筑材料技术领域，原料组成及其质量百分数如下：特种水泥：30‑50质量份；砂：40‑60质量份；微珠：3‑10质量份；高性能减水剂：0.1‑0.5质量份；消泡剂：0.05‑0.2质量份；早强剂：0‑0.15质量份；缓凝剂：0‑0.2质量份；稳定剂：0.05‑0.5质量份；膨胀剂：0.1‑0.5质量份；聚合物乳液：3‑15质量份；水：12‑20质量份；其中，所述特种水泥为硫铝酸盐水泥、高铝水泥中的一种或两种，所述砂为机制砂、河沙中的一种或两种；所述聚合物乳液为纯丙乳液、苯丙乳液、丁苯乳液中的一种或多种。本发明有效解决了现有聚合物砂浆普遍存在早期强度偏低、高流动性下分层离析以及砂浆容重较大、易收缩的技术问题。
