Description
技术领域
本发明属于发泡保温砖领域,一种以页岩、粉煤灰和废碎玻璃粉为主要原料经烧结发泡得到的多孔砖。特别涉及的是建筑保温材料和和石油化工管道和设备保温材料的技术领域。
背景技术
页岩发泡砖是以页岩、粉煤灰和玻璃粉等为主要原料制备的烧结发泡砖。烧结发泡砖,又称发泡陶瓷砖,是一种强度高、耐久性好、保温和隔声效果好的多孔材料。可以广泛应用于建筑保温、化工设备和管道保温等领域。是具有发展前途的21世纪的新型保温材料。因发泡砖选用页岩矿石或土、粉煤灰和碎玻璃等作为主要生产原料,生产成本低、生产工艺绿色环保。这种无机保温材料与苯板和其它高分子保本材料相比,具有阻燃、耐久性好和与墙体结合牢固等优点,因此具有很大的市场竞争优势。
到目前为止,在建筑保温用无机发泡砖在国内已有广泛的研究。目前发泡砖主要有两类:一种是以水泥发泡工艺为基础制备的免烧发泡砖(如专利:200810232188.7和201410347379.3),这种发泡砖制备工艺简单、成本低,但是强度低、吸湿性强,耐久性差,尤其耐冻融性差。另一类保温砖是经烧结法制备的多孔陶瓷类保温材料。烧结多孔保温材料中的气孔的获得有两种途径:一种是如直接烧结发泡;另一种是采用有机泡沫体浸渍、溶胶凝胶工艺、添加多孔剂和浆料发泡剂等方法在室温事先成型发泡,然后经干燥和烧结制得。如欧金福等人发明的一种环保轻质陶瓷砖发泡剂(专利2011101014296)就是用于陶瓷浆料发泡成型,然后坯体经干燥烧结轻质保温砖的。余林文等也是采用浆料添加发泡剂的方法制备了烧结页岩加气砖(非金属矿,2011,34卷,第3期:45-47)。到目前为止还未见利用页岩、粉煤灰等作为主要原料直接烧结制备发泡砖的报道。
发明内容
本发明的目的在于提供一种页岩烧结发泡砖,其主要原料为页岩粉、粉煤灰和废碎玻璃粉,辅以适当发泡剂,用高温烧结发泡工艺制成。发泡砖的主晶相为莫来石等晶体;
所制备的发泡砖具有良好的机械性能和耐久性,其平均抗压强度大于2MPa;密度为0.60~0.75g/cm3;气孔率为60~72%。导热系数为0.0450~0.550W/m*K;耐水解等级为1级,耐水失重率为:0.25~0.30mg/100cm2。
本发明所述的页岩烧结发泡砖,其技术方案是:将下述原料按重量份配比:页岩粉:50~85、粉煤灰:5~30、玻璃粉:5~30、芒硝:0~3、煤粉:1~3。
优选的情况下,所述原料按重量份的配比为:页岩粉:50~70、粉煤灰:10~25、玻璃粉:15~25、芒硝:0~1.5、煤粉:1.5~2.5。
对于上述技术方案中,所用页岩的主要组成成分的质量百分比为:
优选的情况下,所用页岩的主要组成成分的重量百分比为:
所述页岩烧结发泡砖的制备方法,包括下述操作步骤:
1)配料:各种原料经粉磨过100目筛,然后根据确定的原料质量百分比配料;
2)混合:将各种原料采用机械混合机混合均匀;
3)成型:采用半干压法或泥料塑性成型;
4)干燥:自然干燥一天后,再在80~120℃下干燥2~4小时;
5)烧结发泡:升温速度10~30℃/min,烧结保温温度1100~1200℃,保温15~45分钟,然后随炉温冷却。
6)冷加工:经过切割成为成品。
对于上述技术方案中,所述半干压法为将混合好的原料喷加3~5%水后用压砖机在50~100MPa下成型;所述的塑性成型为将混合好的原料添加15~25%的水和成泥料,在模具中所形成泥坯。
对于上述技术方案中,所用煤粉和粉煤灰为发电厂普通煤粉和粉煤灰,玻璃粉是将废碎玻璃瓶罐经粉碎研磨得到的。
本发明突出的特点是:以廉价的资源丰富的页岩和粉煤灰及废碎玻璃为主要原料采用烧结直接发泡法来制备发泡砖,工艺简单,成本低。本发明的发泡砖具有机械强度较高高、密度小、保温性能好,且化学稳定性高、耐久性好。可制成各类管材、板材,可广泛应用于建筑保温隔声和化工管道保温等领域。
