Construction process adopting polyurea protection for old waterproof repair of concrete roof
The invention discloses a construction process adopting polyurea protection for old waterproof repair of a concrete roof, which comprises the following steps: S1, preparing polymer mortar, filling gaps on the surface of concrete with the polymer mortar, and paving the concrete roof with the polymer mortar to obtain a base layer; s2, performing safety protection; s3, a base layer is cleaned, field protection is conducted, and primer is sprayed; s4, spraying polyurea; the raw materials of the polymer mortar in the step S1 comprise 20-35 parts of synthetic resin, 40-55 parts of water, 10-20 parts of gypsum, 10-15 parts of acrylic ester, 2-5 parts of a defoaming agent and 5-10 parts of a thickening agent, and in the step S1, the synthetic resin and the water are placed in a stirring machine to be stirred at the temperature of 25-45 DEG C; by configuring the polymer mortar of the base layer, paving the polymer mortar and matching with the seal primer, the foundation of the polyurea can be greatly increased, gaps of the concrete roof are blocked, the strength of the polyurea can be greatly improved, and vigorous popularization is suggested.
本发明公开了一种混凝土屋面老防水修缮采用聚脲防护的施工工艺，包括以下步骤：S1：配置聚合物砂浆，先将使用聚合物砂浆填充混凝土表面的缝隙，将聚合物砂浆铺满混凝土屋面，得到基层；S2：安全防护；S3：清理基层、现场防护和喷涂底漆；S4：喷涂聚脲；S5：施工验收，所述S1步骤中的聚合物砂浆的原材料为合成树脂20‑35份、水40‑55份，石膏10‑20份、丙烯酸酯10‑15份、消泡剂2‑5份和增稠剂5‑10份，S1步骤中先将合成树脂和水放置在搅拌机内以25‑45摄氏度的温度进行搅拌，本发明通过配置基层的聚合物砂浆和对聚合物砂浆的铺设，再与封闭底漆的配合，就可大大的增加聚脲的基础，并且将混凝土屋面的缝隙堵住，可大大增加聚脲的强度，建议大力推广。
