The invention discloses an acrylic acid modified cement-based material anti-corrosion and anti-freezing polymer emulsion and a preparation method thereof, and belongs to the technical field of building materials. Comprising the following raw materials in parts by weight: 500-650 parts of butyl acrylate, 320-500 parts of styrene, 320-500 parts of methyl methacrylate, 10-100 parts of 2-ethylhexyl acrylate, 6-12 parts of acrylamide, 0-4 parts of acrylic acid, 2-6 parts of an anionic emulsifier, 1-3 parts of a nonionic emulsifier, 1-3 parts of ammonium persulfate, 0.1-1 part of sodium bicarbonate, 1-5 parts of a multifunctional additive, 1-2 parts of a bactericide and 2-6 parts of a dispersant. 0-2 parts of a wetting agent, 0-2 parts of a thickening agent and 1-3 parts of a defoaming agent. The acrylic acid modified cement-based material anti-corrosion and anti-freezing polymer emulsion prepared by the preparation method disclosed by the invention is compounded with a cement-based material, so that the defects of the cement-based material in performance can be obviously improved, and the cement-based material has anti-cracking, waterproof, anti-seepage, high-fatigue-resistance, anti-corrosion and anti-freezing performance and the like under the condition that the original characteristics are kept unchanged; the application range of the cement-based material is widened.
本发明公开了一种丙烯酸类改性水泥基材料防腐抗冻高分子乳液及制备方法，属于建筑材料技术领域，包括如下重量份的原料：丙烯酸丁酯500‑650份、苯乙烯320‑500份、甲基丙烯酸甲酯320‑500份、丙烯酸异辛酯10‑100份、丙烯酰胺6‑12份、丙烯酸0‑4份、阴离子乳化剂2‑6份、非离子乳化剂1‑3份、过硫酸铵1‑3份、碳酸氢钠0.1‑1份、多功能助剂1‑5份、杀菌剂1‑2份、分散剂2‑6份、润湿剂0‑2份、增稠剂0‑2份、消泡剂1‑3份。本发明制备的丙烯酸类改性水泥基材料防腐抗冻高分子乳液通过与水泥基材料进行复合，可明显改善水泥基材料性能上存在的缺点，使得水泥基材料在保持原有特性不变的情况下，同时兼具防裂、防水、防渗、高抗疲劳、防腐防冻等性能，拓宽了水泥基材料的应用范围。
