Fatty acid concrete hydrophobic hole bolt material and preparation method thereof
The invention discloses a fatty acid concrete hydrophobic hole plugging material and a preparation method thereof. The hydrophobic hole plugging material comprises the following components in parts by weight: 30-60 parts of fatty acid, 100-300 parts of hole plugging reinforcing powder, 5-30 parts of a defoaming agent, 5-20 parts of an emulsifier, 5-20 parts of a pH regulator and 570-855 parts of water, the preparation method comprises the following steps: S1, preparing the hole plugging reinforcing powder with the alkali-soluble protective film; s2, adding quantitative water into the reaction kettle, and stirring; s3, sequentially adding the defoaming agent, the emulsifier, the fatty acid and the pH value regulator into the reaction kettle, and stirring; and S4, adding the hole plugging reinforcing powder and the residual water, and stirring to obtain the hydrophobic hole plugging material. By adding the hole plugging reinforcing powder, generation of fatty acid hydration reaction is promoted, meanwhile, the hole plugging and compacting effect is achieved, the negative influence of fatty acid on the mechanical property of concrete is effectively made up, and the hydrophobic hole plugging material is simple in preparation process and short in production period.
本发明公开了一种脂肪酸类混凝土疏水孔栓物及其制备方法，该疏水孔栓物按重量份计包括以下组分：脂肪酸30～60份、堵孔增强粉体100～300份，消泡剂5～30份，乳化剂5～20份，pH调节剂5～20份，水570～855份；其制备方法如下：S1：制备带有碱溶性保护薄膜的堵孔增强粉体；S2：在反应釜中加入定量的水，搅拌；S3：依次在反应釜中加入消泡剂、乳化剂、脂肪酸和pH值调节剂，搅拌；S4：加入堵孔增强粉体和剩余的水，搅拌得到疏水孔栓物。本发明通过加入堵孔增强粉体，促进脂肪酸水化反应的产生，同时起到堵孔致密作用，有效弥补脂肪酸对混凝土力学性能造成的负面影响，且该疏水孔栓物制备工艺简单，生产周期短。
