Abstract The invention relates to a preparation method of a waterproof wall type expanded polytetrafluoroethylene sealing material. The preparation method comprises the specific steps of: mixing of dispersive polytetrafluoroethylene resins and an extrusion assisting agent, preforming, pushing, drying and curing and sintering. The waterproof wall type expanded polytetrafluoroethylene sealing material is mainly used for sealing an airplane floor and a cockpit cover, and can be used for a long time under the environment of -55-260 DEG C. The method for preparing the waterproof wall type expanded polytetrafluoroethylene sealing material can improve the production efficiency and the automation degree in the production process.
