Magnesian cementing material binder and preparation method thereof
The invention discloses a magnesium cementing material binder and a preparation method thereof, the magnesium cementing material binder comprises the following components by mass: 80-120 parts of magnesium oxide powder, 800-1100 parts of a magnesium cementing material, 30-80 parts of fly ash, 10-50 parts of silica fume, 100-500 parts of sand for construction, 2-10 parts of composite phosphate, 3-6 parts of perlite, 10-30 parts of citric acid, 3-5 parts of a foaming agent and 300-500 parts of water, the chemical analysis purity of the composite phosphate is greater than 90%, and the chemical analysis purity of the composite phosphate is greater than 90%. The foaming agent is one or two of alkane and fluorocarbon. The magnesium oxide powder, the composite phosphate and the perlite are added, so that the adhesive property of the adhesive can be enhanced, the adhesive also has relatively strong decomposability and cohesiveness, adhered dust is not easy to separate in the use process, the adhesive also has high temperature resistance and corrosion resistance, and the expansion rate of the magnesium cementing material adhesive is reduced by doping the construction sand, so that the construction efficiency is improved. And the stability after adhesion is improved.
本发明公开了一种镁质胶凝材料粘结剂及其制备方法，其具体质量份数如下：氧化镁粉80～120份、镁质胶凝材料800～1100份、粉煤灰30～80份、硅灰10～50份、建设用砂100～500份、复合磷酸盐2～10份、珍珠岩3～6份、柠檬酸10～30份、发泡剂3～5份和水300～500份，所述复合磷酸盐的化学分析纯度＞90％，所述发泡剂为烷烃和氟碳化合物中的一种或两种。本发明通过加入氧化镁粉、复合磷酸盐和珍珠岩能加强粘接剂的粘附性能，同时还具有较强的分解性和粘结性，使用过程中粘附灰尘不易脱离，还具有耐高温和耐腐蚀的作用，同时掺入建设用砂降低了镁质胶凝材料粘结剂的膨胀率，提高了粘附后的稳定性。
