摘要/Abstract

摘要： 酸激发地质聚合物(ASP-GP)是由铝硅酸盐与酸性溶液反应生成的具有三维立体网络结构的铝硅酸盐无机聚合物。它具有制备工艺简单、机械强度高(最大抗压强度达146 MPa)、耐火耐高温性能好、固封性能及介电性能优异等优点,可作为传统建筑材料、隔热耐火耐高温材料、固封材料、电子封装材料等。此外,低碳节能的制造过程恰好满足绿色环保和节能减排需求,因此,ASP-GP在土木工程、机械工程、航空航天、冶金、核废固封等领域均具有广阔的应用前景。本文依据国内外现有的ASP-GP研究成果,综述了ASP-GP反应机理及力学性能的研究进展,总结了影响ASP-GP力学性能的因素,包括铝硅酸盐活性、激发剂、原材料配合比、养护制度等,以期为ASP-GP的后续研究提供一定的指导。

Abstract: Aluminosilicate phosphate geopolymers (ASP-GP) refer to the aluminosilicate inorganic polymers with three-dimensional network structure generated by the reaction of aluminosilicate and acidic solution (phosphoric acid or phosphate). They can be used as traditional building materials, heat insulation refractory and high temperature resistant materials, solid sealing materials, electronic packaging materials and so on, for their advantages of simple preparation process, high mechanical strength (the maximum compressive strength reaches to 146 MPa), good fire resistance and high temperature resistance, excellent solid sealing performance and dielectric properties. The low carbon-emission and energy-saving preparation fit the demands of friendly-environment, energy conservation and emission reduction. Thus, they are applied widely in the fields of civil engineering, mechanical engineering, aerospace, metallurgy, nuclear waste sealing and others. Based on the existing research achievements about ASP-GP at home and abroad, the development of reaction mechanism and mechanical properties are reviewed. The factors that affect the mechanical properties of ASP-GP are summarized, including aluminosilicate activity, activator, raw material ratio, curing system and so on. It is expected to guide properly the follow-up research of ASP-GP.

Key words: aluminosilicate phosphate geopolymer, reaction mechanism, mechanical property, friendly-environment, energy conservation
