NOVELTY - Preparing Teflon (RTM: Polytetrafluoroethylene) high-temperature cloth comprises arranging glass fiber base in the dipping solution, ultrasonically treating at 80-90?oC for 30 minutes, taking out and dry at 100-120?oC for 30 minutes, and then drying at 125-150?oC for 30 minutes to obtain a special crude fluorocarbon fabric. The crude Teflon (RTM: Polytetrafluoroethylene) fabric is baked at 275-285?oC for 4-6 minutes, sintered at 360-370?oC for 8-15 minutes, and cooled to obtain Teflon (RTM: Polytetrafluoroethylene) high-temperature fabric prepared by impregnation method. The dipping solution is made by mixing 1.1-1.5% modified graphene oxide, 15.2-17.1% high-temperature resistant acrylate, 0.5-0.8% coupling agent KH-560, 1.1-1.2% potassium hydroxide, 30.4-42.8% polytetrafluoroethylene dispersion emulsion and balanced deionized water. USE - Method for preparing Teflon (RTM: Polytetrafluoroethylene) high-temperature cloth based on immersion method, preferably polytetrafluoroethylene coated glass fiber cloth. ADVANTAGE - The process is simple, safe-friendly, and provides Teflon (RTM: Polytetrafluoroethylene) high temperature cloth with excellent adhesive property and high temperature resistance.

The polytetrafluoroethylene dispersion emulsion and deionized water are added into the stirring tank with the remaining raw materials under stirring and mixing for 3-5 hours to obtain the impregnating liquid.
