High-efficiency concrete surface aggregate exposing agent for fabricated member and preparation method of high-efficiency concrete surface aggregate exposing agent
The invention discloses a high-efficiency concrete surface exposed aggregate agent for a fabricated component and a preparation method of the high-efficiency concrete surface exposed aggregate agent. The paint comprises the following components in parts by weight: 15-20 parts of sodium gluconate, 20-30 parts of Wacker dispersible latex, 2-3 parts of an acrylic acid thickener, 1-5 parts of sodium citrate, 50-120 parts of water, 2-5 parts of a pH regulator, 5-10 parts of a defoaming agent, 5-10 parts of phosphate, 10-15 parts of a high-molecular compound, 3-6 parts of a coloring agent and 1-3 parts of an active agent. The adhesion and viscosity of the exposed bone agent can be effectively improved and enhanced through the Wacker dispersible latex and the acrylic acid thickening agent, so that the exposed bone agent is not prone to sagging when being brushed on a vertical face, the brushing effect is good, the exposed bone agent is slightly influenced by temperature and air humidity when being brushed through the added phosphate and the high-molecular compound, and the exposed bone agent is not prone to sagging when being brushed. The permeability on the surface of concrete is good, the bone exposing effect is good, and due to the added pH regulator, when the bone exposing agent is brushed and permeates into cement, steel bars on the shallow layer in the cement cannot be corroded.
本发明公开了一种装配式构件用高效混凝土表面露骨剂及其制备方法,所述露骨剂由以下原料制备而成，重量以份数计:葡萄糖酸钠15‑20份、瓦克可分散乳胶20‑30份、丙烯酸增稠剂2‑3份、柠檬酸钠1‑5份、水50‑120份、pH调整剂2‑5分、消泡剂5‑10份、磷酸盐5‑10份、高分子化合物10‑15份、着色剂3‑6份、活性剂1‑3份。本发明通过以瓦克可分散乳胶和丙烯酸增稠剂可有效提高和增强露骨剂附着性和粘性，使得露骨剂的立面涂刷不易流挂，涂刷效果好，通过添加的磷酸盐和高分子化合物使得露骨剂在涂刷时受温度和空气湿度影响小，在混凝土表面渗透性好，露骨效果好，通过添加的pH调整剂使得露骨剂在涂刷渗透到水泥内部时，不会对水泥内部浅层的钢筋造成腐蚀。
