Phosphoaluminosilicate inorganic polymer as well as preparation method and application thereof
The invention belongs to the technical field of inorganic nonmetal cementing materials, and provides a phosphoaluminosilicate inorganic polymer as well as a preparation method and application thereof. The phosphoaluminosilicate inorganic polymer is prepared from the following raw materials in parts by weight: 50 to 67 parts of precursor raw material, 33 to 50 parts of exciting agent and water, the precursor raw materials comprise metakaolin and active calcium oxide; the active calcium oxide accounts for 3-15% of the weight of the precursor raw material; the activator comprises a phosphoric acid solution. The phosphoaluminosilicate inorganic polymer product obtained according to the formula can meet the requirement that the pH value of the sealing material of the high-level radioactive waste geological repository is smaller than 11, can effectively support cracks and broken rocks, and meets the use requirements of sealing and reinforcing materials of the high-level radioactive waste geological repository. The active calcium oxide is added into the precursor raw materials, so that the working performance and compressive strength of the traditional acid-activated metakaolin-based inorganic polymer can be remarkably improved.
本发明属于无机非金属胶凝材料技术领域，提供了一种磷铝硅酸盐无机聚合物及其制备方法与应用。本发明的磷铝硅酸盐无机聚合物包括以下重量份数的制备原料：前驱体原料50～67份，激发剂33～50份，水；所述前驱体原料包括偏高岭土和活性氧化钙；所述活性氧化钙占所述前驱体原料重量的3～15％；所述激发剂包含磷酸溶液。本发明所述配方得到的磷铝硅酸盐无机聚合物产品，既可以满足高放废物地质处置库密封材料pH值小于11的要求，又能够对裂隙和碎岩进行有效支护，满足高放废物地质处置库密封、加固材料的使用要求。本发明前驱体原料中添加活性氧化钙，可以显著改善传统酸激发偏高岭土基无机聚合物的工作性能和抗压强度。
