Preparation method of geopolymer precursor and product, application and connection method of geopolymer precursor
The invention provides a preparation method of a geopolymer precursor and a product, application and a connection method of the geopolymer precursor. The preparation method of the geopolymer precursorcomprises the following steps that a1, potassium silicate, KOH and deionized water are taken to be made into an alkali activator, and the mass ratio of potassium silicate to KOH to deionized water is100: 4.9-6.5: 90-115; and a2, metakaolin and the alkali activator prepared in the step a1 are mixed and stirred uniformly to prepare a geopolymer precursor, and the mass ratio of metakaolin to the alkali activator is 70-100: 195-222. The preparation method of the geopolymer precursor provided by the technical scheme of the invention is simple and easy to operate, and the synthetic raw materials are low in cost; connection can be successful at a low temperature by using a drying oven, the connection cost is low, energy is saved, and the environment is protected; and when a ceramic aluminum piece is connected by using the product, the combination is firm without no obvious cracks, and the connection strength of the joint is relatively high.
本发明提供了一种地质聚合物前驱体的制备方法及其制品、应用与连接方法，该地质聚合物前驱体的制备方法包括如下步骤：步骤a1：取硅酸钾、KOH和去离子水配制成碱激发剂，其中，所述硅酸钾、KOH和去离子水的质量比为100:4.9‑6.5:90‑115；步骤a2：取偏高岭土和步骤a1所制备的碱激发剂混合，搅拌均匀制得地质聚合物前驱体，其中，所述偏高岭土与所述碱激发剂的质量比为70‑100:195‑222。本发明技术方案所提供的地质聚合物前驱体的制备方法简单，易于操作，且其合成原料成本低廉；本发明使用烘箱在低温下即可连接成功，且连接成本低且节能环保；而且用其连接陶瓷铝件时结合牢固，无明显裂纹，且连接处连接强度相对较高。
