NOVELTY - Anti-melting metal heat-insulating fabric comprises 70-100 pts. wt. pure cotton fabric, 48-65 pts. wt. flame retardant viscose fiber, 40-50 pts. wt. wool fiber, 46-61 pts. wt. carbon nanotubes, and 50-62 pts. wt. phenolic resin. The anti-melting metal heat-insulating fabric is breathable base fabric, aerogel layer, glue layer and flame retardant layer from bottom to top. USE - The heat-insulating fabric is useful in metallurgy, casting, electric welding, glass and other working environments where high-temperature radiation sources and molten metal splashes exist. ADVANTAGE - The heat-insulating fabric: has effects of flame retardancy, heat insulation and high-efficiency protection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the anti-melting metal heat-insulating fabric comprising (1) adding the pure cotton fabric into container, spraying the negative electrolyte solution (0.1-0.3 times the mass of the pure cotton fabric), mass ratio of poly(4-styrene sulfonate) and deionized water in the negative electrolyte solution is 1:6-1:9, drying at room temperature for 3-4 hours, rinsing with deionized water for 4-7 minutes, drying at room temperature for 1-2 hours, placing on a glass plate, electrospraying graphene nanobelt emulsion, reacting for 3-5 hours in high-pressure reaction furnace at 90-95°C and 300-400 MPa, rinsing with acetone aqueous solution for 20-35 minutes, the mass ratio of acetone and deionized water in the acetone aqueous solution is 1:2-1:3, freezing in the refrigerator at -10 to -8℃ for 5-7 hours, adding it in freeze dryer, freezing at 1×10-3 to 3×10-3Pa, -60 to-50℃ for 6-8 hours, and obtaining the aerogel fabric; (2) placing the aerogel fabric in radio frequency plasma generator, evacuating to 8-14 Pa, processing for 5-10 minutes, adding it in glue dispenser, and dispensing 2-3 times to obtain adhesive layer fabric; and (3) preparing flame-retardant layer fabric by blending wool fiber and flame-retardant viscose fiber in a mass ratio of 1:1.2 to 1:1.3; sending adhesive layer fabric and the flame retardant layer fabric to the heat press to obtain the anti-melting metal heat-insulating fabric.
