Description
技术领域
本发明涉及建筑材料技术领域,尤其涉及一种高温泡沫混凝土及自保温砌块加工配方及生产工艺。
背景技术
建筑材料技术领域,近些年,发泡混凝土使用趋于广泛。
泡沫混凝土又称为发泡水泥、轻质混泥土等,是一种低廉且具有不燃性的新型建筑节能材料。轻质混凝土(泡沫混凝土)是通过化学或物理的工艺根据应用需要将空气或氮气、二氧化碳气、氧气等气体引入混凝土浆体中,经过合理养护成型,而形成的含有大量细小的封闭气孔,并具有相当强度的混凝土制品。
泡沫混凝土通常是用机械方法将泡沫剂水溶液制备成泡沫,再将泡沫加入到含硅质材料、钙质材料、水及各种外加剂等组成的料浆中,经混合搅拌、浇注成型、养护而成的一种多孔材料。由于泡沫混凝土中含有大量封闭的孔隙,使其具有下列良好的物理力学性能:轻质;保温隔热性能好;隔音耐火性能好;整体性质量佳;低弹减震;防水性佳;耐久性等。
市场现有泡沫混凝土技术,成品多有强度偏低、使用过程易于开裂、自身吸水等不足。
一种结构稳定性更好、成品质量和强度更佳的泡沫混凝土颇为现有市场说亟需。
发明内容
本发明要解决的技术问题是提供一种高温泡沫混凝土及自保温砌块加工配方及生产工艺,可以有效提升泡沫混凝土的自身结构强度和质量稳定性、使用寿命耐久性,全方面提升泡沫混凝土性能。
为解决上述技术问题,本发明采用的技术方案是:一种高温泡沫混凝土及自保温砌块加工配方及生产工艺,包括如下步骤:
1)、混匀原料:将水220kg、水泥220kg、煤灰380kg、片碱1000g及稳泡剂150g充分混匀形成混桨料;
2)、造气:完成步骤一后,取铝膏500g加水2000g在小搅拌机搅均二十秒,将搅拌均匀的铝膏和水的混合物掺入大搅拌机搅拌二十秒,此步不可超二分种;
3)、浇注入模框后,静置发泡至发泡至理想发泡度,静置过程模框及关联载体不可有振动,以防止塌模;
4)、静置发泡三小时后脱模;
5)、按功能方向将步骤4)所得产品进行切割工序,泡沫混凝土砌块二小时切割,复合自保温砌等七小时切割;
6)、堆放好后用保温膜包好,防止水分散发,待完全硬化后出厂。
作为一种改进,所述混桨料的制作方法包括以下步骤:
1-1)将水温为55℃的水220kg先加入搅拌机,开机后依次加入对应量的稳泡剂、水泥片碱,搅均十秒;
1-2)边搅拌边持续性加煤灰380kg,该过程共需二十秒。

作为一种改进,所述步骤2)中的小搅拌机单批最大搅拌量为10KG。小搅拌机灵活、高频功能特性,对应产品的搅拌效果更佳,匹配大搅拌机的性能特征同时使用,使得对应材料的性能,最大化彰显,匹配工艺效果更佳,工艺性能更稳定。
作为一种改进,所述步骤2)铝膏500g加水2000g在小搅拌机搅拌工序与步骤1)同步进行,搅拌完成后同时倒入步骤1)混浆料,以保持铝膏加水的搅拌混合的特性,由于两个步骤组分特性特征,保持铝膏加水的搅拌混合的特性及时再次混组,以更好实现与步骤1)混浆料混溶。
作为一种改进,所述步骤3)中发泡度为发泡成型的产品密度达到195-230千克/立方米。对应比例的混料实现最佳的成型效果、及产品特性。
作为一种改进,所述步骤6)保温膜包好后堆放周期为18-50天,完全硬化。
