NOVELTY - A low-carbon energy-saving heat-insulating material comprises 50-60 pts. wt. fly ash, 20-30 pts. wt. calcium silicate, 5-20 pts. wt. perlite, 10-15 pts. wt. diatomite, 10-20 pts. wt. cement, 0.2-0.4 pt. wt. aluminum powder, 4-6 pts. wt. polypropylene fiber, 5-10 pts. wt. phenolic resin, 1-3 pts. wt. polycarboxylic acid high-efficiency water reducing agent, 1-3 pts. wt. hydroxypropyl starch, 2-7 pts. wt. graphene, 4-8 pts. wt. hollow glass microsphere, 5-8 pts. wt. diatomite, 10-20 pts. wt. expanded vitrified microsphere, 1-2 pts. wt. foaming agent, 0.5-2 pts. wt. surfactant, 0.1-1 pt. wt. crosslinking agent and 0.4-0.8 pt. wt. catalyst. USE - Low-carbon energy-saving heat-insulating material used in building material application. ADVANTAGE - The low-carbon energy-saving heat-insulating material has synergistic effect, synergistically improves the tensile strength of the heat insulating material and reduces the heat conducting coefficient, and is easy to break, and the porous closed structure in the interior can increase the closed porosity of the porous fly ash material, so as to enhance the mechanical property of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of low-carbon energy-saving heat-insulating material.
