Anti-freezing high-temperature-resistant concrete repairing agent and preparation method thereof
The invention discloses an anti-freezing high-temperature-resistant concrete repairing agent and a preparation method thereof. The method comprises the following steps of heating acrylic acid to 90 DEG C, adding sodium dodecyl benzene sulfonate, propyl acetate and ethylenediaminetetraacetic acid, conducting even mixing, then adding water and conducting even stirring; conducting cooling to 60-70 DEG C, adding calcium oxide, cumene hydroperoxide, sodium sulfite, sodium hydroxide, sodium hypochlorite and urea, and conducting reacting for 2-5 hours; and adding cement and river sand, and conducting stirring for 5-10 minutes. The repairing agent does not crack in an extreme environment, has excellent heat resistance and frost resistance as a repairing agent for buildings, and is relatively wide in application.
本发明公开了一种防冻耐高温混凝土修补剂及其制备方法，该方法包括以下步骤：将丙烯酸加热至90℃，加入十二烷基苯磺酸钠、醋酸丙酯、乙二胺四乙酸，混合均匀，然后加入水搅拌均匀；降温至60‑70℃，加入氧化钙、异丙苯过氧化氢、亚硫酸钠、氢氧化钠、次氯酸钠和尿素，反应2‑5h；加入水泥、河沙，搅拌5‑10min，即可。本发明在极端环境下不开裂，作为建筑用的修补剂，具有优良的耐热性能和抗冻性能，应用较广泛。
