Abstract

The invention belongs to the scope of preparation of geopolymer foaming materials, and specifically discloses a preparation method of geopolymer open-cell foaming materials, which is characterized in that the geopolymer raw materials, alkali activators, hydrogen peroxide, twelve The raw material slurry of sodium alkylbenzene sulfonate is foamed to obtain the product; sodium dodecylbenzene sulfonate is 0.2-1% of the weight of the geopolymer; H2O2 is 0.01-5% of the weight of the geopolymer raw material. The present invention innovatively uses sodium dodecylbenzene sulfonate to control the pore structure, and further through the synergistic control of the dosage of sodium dodecylbenzenesulfonate, foaming agent and its dosage, etc., can unexpectedly prepare the A geopolymer open-cell foaming material with a large specific surface area, uniform distribution of pores, and a relatively large pore diameter of the interconnecting pores was developed.

Description

A kind of geopolymer open-cell foaming material and its preparation method and application Technical field:

[0001] The present invention belongs to the scope of foam material preparation, in particular to a method for preparing geopolymer open-cell foam material. Background technique: Geopolymer is a new type of green inorganic cementitious material, which was first introduced by French scholar Joseph Davdovists. propose. Geopolymers can be made of materials containing active silicon-alumina materials (such as metakaolin, fly ash, slag, tailings, etc.) at room temperature or It is generated by the excitation of alkali solution at lower temperature. Due to the special inorganic polycondensation three-dimensional network structure, the geopolymer has both The performance characteristics of cement, glass and ceramics, with high strength, high temperature resistance, waterproof, acid and alkali corrosion resistance and other characteristics. Due to this series Due to ...
