Green and environment-friendly dry powder waterproof agent for cement
The invention discloses a green and environment-friendly dry powder waterproof agent for cement. The green and environment-friendly dry powder waterproof agent comprises 100 g of calcium stearate, 10 g of trisiloxane, 15 g of propylene glycol and 10 g of a powdery water reducing agent. TA preparation method of the green and environment-friendly dry powder waterproof agent comprises the following steps: firstly, weighing 100 g of calcium stearate, then adding 10 g of polyether trisiloxane, additionally adding 15 g of propylene glycol, fully and uniformly stirring by using a blade type stirrer, simultaneously adding 10 g of the powdery water reducing agent, uniformly stirring for about 40 minutes, and sealing and packaging to obtain the cement dry powder waterproof agent containing 75% of calcium stearate. The waterproof powder using the calcium stearate waterproof agent as a carrier is simple to make, environment-friendly and pollution-free, and can reach the national primary standard; the waterproof powder prepared by using the calcium stearate waterproof agent as the carrier is superior to other waterproof powders; when the waterproof powder prepared by the method is used in cement products and cement mortar, the dosage can be reduced, and the effect is better; and the addition amount of the waterproof powder is within 0.4%, and the water absorption rate is within 8.0% after the waterproof powder is soaked in water for 48 hours.
本发明公开了一种绿色环保用于水泥的干粉防水剂，按照重量由以下原料组成：硬脂酸钙100g、三硅氧烷10g、丙二醇15g、粉状减水剂10g；制备方法如下：首先称取硬脂酸钙100g，然后加入聚醚三硅氧烷10g，另加15g丙二醇，用叶片式搅拌器充分搅匀，同时加入粉状减水剂10g搅匀，时间约40min，密封包装，即可得到含硬脂酸钙75％的水泥干粉防水剂，本发明用硬脂酸钙防水剂为载体做的防水粉，做工简单，环保无污染，可达到国家一级标准；用硬脂酸钙防水剂为载体制备的防水粉优于其它防水粉；此方法制备的防水粉用于水泥制品及水泥砂浆中可减少用量，效果更好；此专利防水粉加量在0.4％之内，泡水48小时吸水率为8.0％之内。
