Self-hardening aluminosilicate binder composition and application method thereof
The invention discloses a self-hardening aluminosilicate binder composition and an application method thereof. The binder composition comprises the following raw materials in parts by weight: 15-20 parts of aluminosilicate, 20-30 parts of modified resin, 1-1.5 parts of sodium carbonate, 1-3 parts of sodium dodecyl sulfate, 10-15 parts of ethanol, 3-5 parts of graphene oxide and 3-5 parts of triethylene tetramine. The terminal hydroxyl group on the intermediate 6 reacts with one isocyanate group on toluene-3, 5-diisocyanate, and the rest isocyanate group reacts with the hydroxyl group on the epoxy resin to prepare the modified resin, and the modified resin takes polyimide as a connecting chain, so that the mechanical property of the modified resin is improved, and the service life of the modified resin is prolonged. The main chain of the resin molecule contains an aryl ether sulfone structure and a large number of ketone groups, so that the toughness of the modified resin is enhanced, the mechanical property of the binder composition is greatly improved by blending with the graphene oxide, and meanwhile, the binding effect of the binder is further improved by compounding with the aluminosilicate.
本发明公开了一种自硬铝硅酸盐粘结剂组合物及其应用方法，该粘结剂组合物包括如下重量份原料：铝硅酸盐15‑20份、改性树脂20‑30份、碳酸钠1‑1.5份、十二烷基磺酸钠1‑3份、乙醇10‑15份、氧化石墨烯3‑5份、三乙烯四胺3‑5份；中间体6上的端羟基与甲苯‑3,5‑二异氰酸酯上的一个异氰酸酯基反应，剩余的异氰酸酯基与环氧树脂上的羟基反应，制得改性树脂，该改性树脂以聚酰亚胺作为连接链，使得改性树脂的机械性能提升，且该树脂分子主链上含有芳醚砜结构以及大量酮基，使得改性树脂的韧性增强，进而与氧化石墨烯共混大大提升了粘结剂组合物的机械性能，同时与铝硅酸盐复配使得粘结剂的粘结效果进一步的提升。
