Heat-conducting anti-cracking high-ductility geopolymer composite material and preparation method thereof
The invention discloses a heat-conducting anti-cracking high-ductility geopolymer composite material and a preparation method thereof. The geopolymer composite material comprises the following components: an aluminum-silicon mineral material, a nano material and an alkaline composite catalyst. The aluminum-silicon mineral material is fly ash and attapulgite. The nanometer material is nanometer graphite powder and nanometer zirconia. A fiber material is ceramic fibers and calcium sulfate whiskers. Chemical additives include a water reducing agent, a defoaming agent, a retarder and a fiber dispersing agent. The alkaline composite catalyst comprises sodium methoxide, sodium ethoxide, hydrotalcite and water-soluble sodium stearate. The heat-conducting anti-cracking high-ductility geopolymer composite material provided by the invention is prepared by taking the aluminum-silicon mineral material, the nano material and the fiber material as main raw materials, carrying out geopolymerization reaction under the action of the alkaline composite catalyst and the chemical additives, and performing forming, maintaining, condensing and hardening. The ductility, the toughness and the crack resistance of the geopolymer material can be greatly improved.
