Anti-cracking concrete filling agent and production process thereof
The invention discloses an anti-cracking concrete filling agent, which is prepared from the following raw materials in parts by weight: 25-35 parts of modified nanoparticles, 30-50 parts of a high-adsorption filler, 10-20 parts of sodium hydroxide, 10-15 parts of acrylic resin emulsion, 10-15 parts of ethylene oxide, 10-15 parts of urea and 5-15 parts of kaolin. The production process comprises: adding modified nanoparticles and a high-adsorption filler into an acrylic resin emulsion, uniformly mixing, heating in a water bath at 40-50 DEG C, and magnetically stirring for 4-5 hours to obtain amixed solution D; and sequentially adding ethylene oxide, sodium hydroxide, urea and kaolin into the mixed solution D, uniformly stirring, and circularly heating with hot air at 80-100 DEG C for 2-3 hours to obtain the concrete filling agent. The invention further discloses a production process of the anti-cracking concrete filling agent. According to the invention, after the prepared filling agent is mixed with concrete, the concrete can be endowed with excellent stability, and the cracking resistance of the concrete is enhanced.
本发明公开一种防开裂的混凝土用填充剂，由如下重量份原料制成：25‑35份改性纳米粒子，30‑50份高吸附填料，10‑20份氢氧化钠，10‑15份丙烯酸树脂乳液，10‑15份环氧乙烷，10‑15份尿素，5‑15份高岭土；将改性纳米粒子和高吸附填料加入丙烯酸树脂乳液中，混合均匀，40‑50℃水浴加热，磁力搅拌4‑5h，制得混合液D；将环氧乙烷、氢氧化钠、尿素和高岭土依次加入混合液D中，搅拌均匀，在80‑100℃下热风循环加热2‑3h，制得混凝土用填充剂；本发明还公开了一种防开裂的混凝土用填充剂的生产工艺；制成的填充剂与混凝土结合后能够赋予混凝土优异的稳定性，增强其抗开裂性能。
