NOVELTY - Inorganic heat insulation paste with ultra-light and low thermal conductivity composite aerogel graphene comprises 50-60 pts. wt. water, 40-60 pts. wt. inorganic aerogel, 30-50 pts. wt. composite aerogel, 8-15 pts. wt. calcium hydroxide solution, 5-10 pts. wt. vitrified microbeads, 5-15 pts. wt. polypropylene fiber, 20-35 pts. wt. hydraulic gelling material, 9-15 pts. wt. additive, 5-11 pts. wt. cellulose ether, 5-10 pts. wt. mica powder and 3-7 pts. wt. horn powder. The preparation of the inorganic thermal insulation paste comprises adding inorganic aerogel and composite aerogel to the reagent bottle to mix with water, stirring, adding cellulose ether, hydraulic gelling material and auxiliary agent to the solution after mixing and stirring, adding polypropylene fiber silk, drying the material in a ventilated place, pouring calcium hydroxide solution, mica powder, additives, vitrified microspheres and horn powder into the stirring pot together and stirring. USE - The inorganic heat-insulation paste is useful in building heat insulating material. ADVANTAGE - The paste: can solve the problem that cannot reach the non-combustion effect and the paste material quality is high; is composed of inorganic material, which prevents the fire from spreading, the combustion level is A level; has good plasticity; can adopt blade coating; needs small construction space requirement; has very simple and convenient construction; does not contain volatile harmful substance, production process flow; is safe and environmentally-friendly and non-toxic, and enhances the safety of production and construction.
