Description

菱镁板材轻质发泡剂
技术领域
本发明涉及建筑材料，是一种菱镁板材轻质发泡剂。
背景技术
现有以粉煤灰、氧化镁、氯化镁为主要原料生产框架结构非承重轻质隔墙板、轻质吊顶天花板等制品时，必须使用发泡剂进行发泡。现有的发泡剂起泡率低、泡沫稳定性差，制成的制品重量重、强度低，成本高。
发明内容
本发明的目的在于，提供一种起泡率高、泡沫稳定，制品体轻、强度高，用量少、成本低，防火、防水性能好，无放射性、环保，应用广泛的菱镁板材轻质发泡剂。
本发明的目的是由以下技术方案来实现的：一种菱镁板材轻质发泡剂，其特征是：按重量组份其组成为：
一级松香        15～25份
优质骨胶        10～20份
氢氧化钠        1.5～2.5份
苯丙乳液        3～5份
工业级盐酸      0.2～0.5份
水              55～65份。
由于本发明的菱镁板材轻质发泡剂是由15～25份的一级松香、10～20份优质骨胶、1.5～2.5份氢氧化钠、55～65份水及作为防水剂的3～5份苯丙乳液和作为阳离子活性剂的0.2～0.5份工业级盐酸优选配制组成的，它具有起泡率高、泡沫稳定，制品体轻、强度高，用量少、成本低，防火、防水性能好，无放射性、环保，应用广泛等优点。以粉煤灰、氧化镁、氯化镁为主要原料，使用本发泡剂生产的框架结构非承重轻质隔墙板、轻质吊顶天花板等制品与使用现有的发泡剂生产同一产品相比，体轻30～40％，节约发泡剂30～40％，成本低30～40％。
具体实施方式
下面结合实施例对本发明作进一步描述。
菱镁板材轻质发泡剂的实施例1-3各原料的重量配比见下表。重量单位：kg
  例号   一级松香   优质骨胶   氢氧化钠   苯丙乳液   工业级盐酸   水
  1   15   10   1.5   3   0.2   55
  2   20   15   2   4   0.35   60
  3   25   20   2.5   5   0.5   65
以实施例2为例说明菱镁板材轻质发泡剂制作方法如下：按重量组份的一级松香20kg、优质骨胶15kg、氢氧化钠2kg、苯丙乳液4kg、工业级盐酸0.35kg和水60kg进行备料。将上述配比的各原料放置于熬制容器中，在60～75℃温度下，加热40～60分钟，然后自然冷却至常温制成。在整个制作过程中需要连续进行搅拌。
