|
摘要: |
以粉煤灰、增钙剂、丙稀酸系乳胶粉、水泥、复合激发剂、纤维素醚、聚丙烯纤维为主原料,配以适量的粉状消泡剂、防霉剂,制得了一种大掺量粉煤灰干粉外墙腻子;探讨了粉煤灰、水泥、乳胶粉、纤维素醚、复合激发剂、聚丙烯纤维掺量对大掺量粉煤灰干粉外墙腻子性能的影响;确定了大掺量粉煤灰干粉外墙腻子的配方;测试了它的物理化学性能.研究结果表明,所配制的大掺量粉煤灰干粉外墙腻子中粉煤灰掺量可以大于70%(质量分数),其成本低廉,是一种具有优良理化性能和施工性能的环保型腻子;同时还为粉煤灰的综合利用开辟了一条新途径,具有良好的经济效益和社会效益. |

Abstract: |
Using fly ash,calcium-adding agent,acrylic re-dispersible latex powder,cement,compound activator,cellulose ether and polypropylene fiber as main raw materials,a high-volume fly ash powder putty for exterior wall was compounded with appropriate powder antifoaming agent and anti-mildew agent.The performance effect of fly ash,acrylic re-dispersible latex powder,cement,compound activator,cellulose ether and polypropylene fiber on high-volume fly ash powder putty for exterior was discussed.The formulation of powder putty for exterior was confirmed.The physical and chemical properties of high-volume fly ash powder putty for exterior wall were tested.The results showed that,this high-volume fly ash powder putty for exterior wall containing 70%(by mass) fly ash,whose cost is much lower,is a high-physical and chemical properties and workability green putty.This research also develops a new way to utilize fly ash with good economy and society benefit. |
Key words: fly ash,powder putty for exterior wall,bonding strength,performance,formulation |
