一种清水混凝土专用脱模剂及其制备方法
摘要：
本发明涉及一种清水混凝土专用脱模剂及其制备方法；所述清水混凝土专用脱模剂为水分散溶液，其原料组分及组分占原料总量的质量百分比分别为：有机改性硅油62％～75％、聚丙烯酰胺0.01％～0.05％、脂肪酸酰胺3％～5％、有机胺0.01％～0.2％、聚氧丙烯甘油醚10％～15％、水11％～18％。先将聚丙烯酰胺溶于水中，升温至35～55℃，搅拌均匀后加入其他组分，再搅拌后自然冷却，即得到一种清水混凝土专用脱模剂。本发明能够有效的改善清水混凝土水泥制品的外观效果，使其表面光滑无气泡，是一种清水混凝土专用脱模剂，环保无污染、成本低廉，使用时可以加入1～7.5倍水稀释，且喷涂一次可以连续脱模3～4次，性能稳定。
摘要（英）：

The invention relates to a releasing agent special for bare concrete and a preparation method thereof. The releasing agent special for the bare concrete is a water dispersion solution and comprises raw materials including organic modified silicone oil accounting for 62%-75% of the total mass of the raw materials, polyacrylamide accounting for 0.01%-0.05% of the total mass of the raw materials, fatty acid amide accounting for 3%-5% of the total mass of the raw materials, organic amine accounting for 0.01%-0.2% of the total mass of the raw materials, polyoxypropylene glycerol ether accounting for 10%-15% of the total mass of the raw materials and water accounting for 11%-18% of the total mass of the raw materials. The polyacrylamide is firstly solved in the water, the temperature is improved to be 35-55 DEG C, other components are added after even stirring, natural cooling is performed after re-stirring to obtain the releasing agent special for the bare concrete. The appearance effect of a bare concrete cement product can be improved, the surface of the bare concrete cement product can be smooth and free of air bubbles, the releasing agent special for the bare concrete is environmentally friendly, free of pollution and low in cost, 1-7.5 times of water can be added for dilution when the releasing agent is used, 3-4 times of continuous releasing can be performed through one-time spraying, and performance is stable.
