The invention discloses a solid polytetrafluoroethylene sealing strip provided with a hole. The solid polytetrafluoroethylene sealing strip provided with the hole comprises a polytetrafluoroethylene body. The polytetrafluoroethylene body comprises a first body part and a second body part, wherein the first body part is provided with an arc-shaped bottom surface, the second body part is formed on the first body part, and the section of the second body part is in the shape of an inverted trapezoid. A step part is formed between one side face of the second body part and the top surface of the first body part. The middle portion of the top surface of the second body part is concave, so that a groove with the right-angled bottom is formed. The hole with the oval section is formed in the second body part in the extension direction of the second body part. According to the solid polytetrafluoroethylene sealing strip provided with the hole, a polytetrafluoroethylene sealing material is adopted, polytetrafluoroethylene has extremely excellent chemical stability and an extremely low friction coefficient, and particularly, since filled polytetrafluoroethylene is added and filled with reinforcing materials, physical and mechanical properties are further improved on the basis that original excellent properties are maintained.
Description
technical field [0001] The application belongs to the technical field of ship transportation, and in particular relates to a polytetrafluoroethylene solid core cavity sealing strip. Background technique [0002] Among polymer materials, rubber is widely used in shock-absorbing products because of its good mechanical properties and high resilience, and its elastic modulus is very small. But in general, the mechanical strength of rubber materials is low, the wear resistance is poor, the friction resistance generated during movement is large, and there are certain limitations in the resistance to media. [0003] Many places on existing cargo ships need to use rubber parts to play the role of shock absorption, etc., and the existing rubber parts for cargo ships, due to poor salt spray resistance, cause layer blistering or aging due to hard and brittle surfaces, resulting in huge damage. Security risks. Contents of the invention [0004] The object of the present invention is...
