High-performance concrete surface aggregate exposing agent for assembly type component and preparation method of high-performance concrete surface aggregate exposing agent
The invention discloses a high-performance concrete surface exposing agent for an assembly type component and a preparation method of the exposing agent . The exposing agent is prepared from the following raw materials in parts by weight: 600-700 parts of water; 5 to 15 parts of a covering agent; 250 to 350 parts of hydroxy carboxylate; 0 to 50 parts of phosphine and salts thereof; 0 to 50 parts of phosphate; 5 to 30 parts of layered silicate; 15 to 35 parts of high-molecular polymer; 2 to 10 parts of a defoaming agent; 5-20 parts of a penetrant; 1 to 10 parts of a surfactant; 0 to 30 parts of water-based color paste; and 2 to 15 parts of a preservative. According to the invention, hydroxy carboxylate, phosphine and its salt and phosphate are used as main delayed coagulation components, corrosion is avoided, the later strength is not affected while efficient coagulation of the surface layer of the fabricated member is realized, and the exposing agent has the advantages of ecological environmental protection, efficient delayed coagulation, durability and stability; and the problems of easy sagging, weak adhesive force, tedious preparation process and the like during vertical face mold brushing of a mole cricket agent are solved.
本发明公开了一种装配式构件用高性能混凝土表面露骨剂及其制备方法，所述露骨剂包括如下重量份的组份原料制备而成：水：600‑700份；遮盖剂：5‑15份；羟基羧酸盐：250‑350份；膦及其盐：0‑50份；磷酸盐：0‑50份；层状硅酸盐：5‑30份；高分子聚合物：15‑35份；消泡剂：2‑10份；渗透剂：5‑20份；表面活性剂：1‑10份；水性色浆：0‑30份；防腐剂：2‑15份；本发明以羟基羧酸盐、膦及其盐和磷酸盐作为主要缓凝成分，无腐蚀性，在实现装配式构件表层高效混凝的同时，不影响后期强度，具有生态环保、高效缓凝、持久稳定；解决了蝼蛄剂立面刷模时易流挂、附着力弱、制备工艺繁琐等问题。
