▎ 摘　　要

NOVELTY - Heat-insulating graphene-based thin composite film comprises 29-46 pts. wt. water, 0.25-0.5 pts. wt. stabilizer, 0.25-0.5 pts. wt. dispersing agent, 25-35 pts. wt. aqueous glass solution, 4-5 pts. wt. silicone emulsion, where rare earth has particle size of 10000 mesh or more, and nanosilver fiber has particle size of 10000 mesh or more with weight fraction of 3-6, graphene has particle size of 10000 mesh or more, and ferrite powder has particle size of 10000 mesh or more. The heat-insulating graphene-based thin composite film is prepared by placing 30-46 pts. wt. water in container, adding weighting agent, dispersing agent, defoaming agent and water glass solution with constant stirring and mixing uniformly, adding rare earth, nano silver fiber and graphene with constant stirring and mixing well, then adding silicone emulsion, placing material into vacuum chamber, and loading high-temperature heat-insulated graphite-based composite material. USE - Heat-insulating graphene-based thin composite film applied to titanium alloy, stainless steel, high temperature alloy and composite materials. ADVANTAGE - The heat-insulating graphene-based thin composite film has high temperature resistant, corrosion resistant, wear resistant and long service life. DETAILED DESCRIPTION - Coating into automatic coating device, evacuating chamber to form heat-insulated graphite thin-film composite material film on surface of material by using automatic coating device.
