Description

砂浆塑化剂及其用途
技术领域
本发明涉及一种建筑材料，特别是一种砂浆塑化剂及其用途。
背景技术
随着建设规模的扩大和建筑技术的发展，对面广量大的建筑砂浆提出了新的质量和净化环境的要求。目前，建筑施工中广泛采用的各种砂浆，例如1∶1∶4及1∶1∶6抹灰砂浆，其各种性能技术指标也并不理想，例如，抗裂抗渗，缓凝效果，可操作性，粘聚效能等都有待于提高，另外，由于砂浆含有较大量的石灰膏，一方面其材料成本较高，另一方面其堆放和运输对环境带来一定的影响。
发明内容
本发明的目的提供一种砂浆塑化剂，具有替代砂浆中的石灰膏或微沫剂的全部作用，同时也可以替代石灰膏掺入内墙腻子中，其各种性能技术指标替代后更优越，且降低成本。
本发明的砂浆塑化剂，其按重量计基本组成为：
    甲基纤维素              2～3％
    混凝土引气剂            3～5％
    木质素磺酸钙            30～50％
    混凝土高效减水剂        10～20％
    钾基膨润土              30～50％
本发明砂浆塑化剂用于制备砂浆，替代原砂浆的石灰膏。
本发明砂浆塑化剂用于替代抹灰砂浆中石灰膏制备砂浆，其具体按重量计为：
    水泥                  1份
    砂浆塑化剂            0.15～0.35％份
    砂                    4～8份
    水                    适量
本发明砂浆塑化剂替代普通砂浆中的石灰膏，具有如下优点：
使用本发明0.125公斤可替代约50公斤石灰膏，在技术指标和操作性能上替代后更为优越，表现为增强塑化、抗裂抗渗、缓凝效果优、操作轻松、易粘聚等方面；且在工程造价上与使用石灰膏节省20-30％；在保持与基准样等强度的前提下，还可以节省水泥用量10％左右，加之还可以扩大浆体的粉刷面；另外以1∶400左右替代了石灰膏，减少了建筑材料的现场堆放和运输的噪杂，有效地促进了文明施工和环境保护，其社会、经济效益颇为显著。本发明可广泛适用于工业、民用建筑和各类构筑物的抹灰砂浆、生产干粉砂浆、预拌砂浆和现场配制的各类抹灰砂浆。
具体实施方式
下面结合实施例对本发明进一步说明：
制备例1：
制备100Kg砂浆塑化剂包括经细磨甲基纤维素2Kg，混凝土引气剂4Kg，木质素磺酸钙40Kg，混凝土高效减水剂15Kg，钾基膨润土39Kg充分搅拌混合制得该砂浆塑化剂。
