Waterproof self-leveling material as well as preparation method and application thereof
The invention relates to the technical field of building materials, in particular to a self-leveling material and a preparation method and application thereof. The waterproof self-leveling material comprises a basic material and a protective material, the protective material is prepared from the following components in parts by mass: 10 parts of acrylic emulsion, 2 to 3 parts of nano aluminum oxide, 1 to 3 parts of fumed silica and 0.5 to 1.0 part of nano fiber. In a base material system of the self-leveling material, the semi-hydrated gypsum, the cement and the filler are used as gel materials, so that the hardening characteristic of the gel materials can be well regulated and controlled; the nano silicon dioxide is added, so that the compressive strength of the mortar can be remarkably improved; the protective material is based on the water-based acrylic emulsion and is added with nanofibers, and the nanofibers can form a layer of interface film on the self-leveling surface, so that the situation that the surface strength of the self-leveling surface is reduced due to moisture absorption can be prevented, water vapor volatilization of the self-leveling surface in the drying process can be guaranteed, and smooth increase of the product strength is promoted.
本发明涉及建筑材料技术领域，尤其涉及一种自流平材料及其制备方法和应用。一种防水自流平材料，包括基础料和防护料；所述的防护料包括以下质量份的组分：丙烯酸乳液10份、纳米三氧化二铝2~3份、气相二氧化硅1~3份、纳米纤维0.5~1.0份。本发明自流平材料的基础料体系中，以半水石膏、水泥和填料作为凝胶材料，能够较好地调控凝胶材料的硬化特性；添加有纳米二氧化硅，能够显著提高砂浆的抗压强度；防护料以水性丙烯酸乳液为基础，且添加有纳米纤维，纳米纤维会在自流平表面形成一层界面薄膜，既可防止自流平表面因吸湿而表面强度降低，又能保证自流平在干燥过程中的水汽挥发，促进产品强度的顺利增长。
