Description
技术领域
本发明涉及预制品,具体涉及一种水拌轻质预制砂浆。
背景技术
目前建筑业需要重量轻且强度好、裂纹少且耐火性能高的预制品。如排烟气道、轻质隔墙等。排烟气道或轻质隔墙在重量不超重的情况下,强度达到技术要求难度较大,反之如果强度达到技术要求,但产品的重量通常会超重,生产成本高,安装难度大。
轻质预制砂浆,能更好的满足以上要求,且耐火性能大幅提高。
轻质预制砂浆,主要由水泥、脱硫石膏、炉渣,再加少量珍珠岩粉,加水搅拌而成。然后注入所需生产的产品模具内。过15分钟后即可脱模,若室温低于10℃时加入少许萘系减水剂,这样生产出来的排烟气道或轻质隔墙产品,具有重量轻、强度好、无裂纹且耐火性能高等优点。
发明内容
本发明针对上述问题,提供了一种水拌轻质预制砂浆。
本发明采用的技术方案是:一种水拌轻质预制砂浆,由水泥、脱硫石膏、炉渣、珍珠岩颗粒、水、铁黄粉、氧化铝粉、可散性乳胶粉及玻璃纤维丝组成;所述水泥、脱硫石膏、炉渣、珍珠岩颗粒、水、铁黄(分子式Fe2O3·xH2O)粉、氧化铝(Al2O3)粉、可散性乳胶粉及玻璃纤维的重量比为:5-25:35-45:5-10:1-5:35-40:0.1-0.5:0.1-0.5:0.1-0.5:0.1-0.5。
本发明的优点:
本发明在水拌轻质预制砂浆中加入铁黄粉和氧化铝粉,提高了产品强度,相应缩短脱模时间,提高耐火性能。
