▎ 摘　　要

NOVELTY - Inorganic thermal insulation, fireproof and hydrophobic coating comprises inorganic silicon solution, graphene, white quartz sand, heavy calcium carbonate, polypropylene fiber, titanium dioxide, mica powder, sodium hexametaphosphate, phase change masterbatch, ceramic beads, nano silica, cement, calcium formate, aluminum powder, antiseptic, leveling agent, defoamer, hydrophobic agent, AMP (RTM: multifunctional neutralizer containing 2-amino-2-methyl-1-propanol)-95 regulator and deionized water. USE - Inorganic thermal insulation, fireproof and hydrophobic coating used for wall body (claimed). ADVANTAGE - The inorganic thermal insulation, fireproof and hydrophobic coating adopts phase change masterbatch using vermiculite powder as raw material, which cooperates with calcium formate, aluminum powder, cement and other components, and can well play the functions of thermal insulation, fire prevention and hydrophobicity, and reduce the harm to the environment, and has potential market value. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a preparation method of an inorganic thermal insulation fire retardant hydrophobic paint, which involves adding inorganic silicon solution, graphene, heavy calcium carbonate, titanium dioxide, mica powder, sodium hexametaphosphate, nano silica, leveling agent, defoaming agent, deionized water, and stirring at 1200 revolutions/minute for 30 minutes; adding white quartz sand, polypropylene fiber, phase change masterbatch, ceramic microbeads, and hydrophobic agent to the stirring irrigation and continue stirring at 400 revolutions/minute for 30 minutes; adjusting the pH to 9 with AMP-95 regulator, and finally adding preservatives, and packaging them in plastic drums for use; and packing cement, calcium formate and aluminum powder separately for use; and (2) a wall body comprises an inorganic thermal insulation fire retardant and hydrophobic coating, where inside and outside of the wall are coated with an inorganic thermal insulation water-based paint layer, and the thickness of the coating is 1-2 mm.
