Marine watertight door sealing strip
The invention discloses a marine watertight door sealing strip. The marine watertight door sealing strip comprises a polytetrafluoroethylene sponge core and skin wrapping the outer side of the polytetrafluoroethylene sponge core. The skin comprises a first skin body, second skin bodies and a third skin body, wherein the first skin body wraps the top surface of the sponge core and is arranged horizontally, the second skin bodies wrap the left side and the right side, opposite to each other, of the sponge core, and the third skin body wraps the bottom surface of the sponge core and is arranged horizontally; the second skin body comprises upper skin bodies which are arranged oppositely and are spaced from each other by a first distance and lower skin bodies which are arranged oppositely and are spaced from each other by a second distance, the first distance is larger than the second distance, and the top ends of the lower skin bodies are connected to the bottom ends of the upper skin bodies through concave arc-shaped grooves. According to the marine watertight door sealing strip, polytetrafluoroethylene sealing materials are adopted, polytetrafluoroethylene has the extremely excellent chemical stability and the extremely-low friction coefficient, and particularly, the sealing strip is filled with polytetrafluoroethylene; due to the fact that the sealing strip is filled with reinforced materials, the physical and mechanical properties of the sealing strip are further improved on the basis that the original excellent performance of the sealing strip is maintained.
