Abstract

The invention discloses a hatch cover sealing strip. The hatch cover sealing strip comprises a polytetrafluoroethylene body, wherein the body comprises a first body which has a first width, and a second body which is formed on the first body and has a second width, and the second width is greater than the first width; three holes are formed in parallel in the middle of the body in an extension direction of the body, and the section of each of the holes is rectangular; and an arc surface is formed on the edge of the bottom end of the first body, and an arc surface is formed on the edge of the top end of the second body. According to the hatch cover sealing strip disclosed by the invention, polytetrafluoroethylene sealing materials are adopted, polytetrafluoroethylene, especially filled polytetrafluoroethylene has extremely predominant chemical stability and quite low friction coefficients, and particularly stuffing reinforcing materials are added, so that on the basis of maintaining original excellent properties, physical and mechanical properties are further improved.

Description

technical field [0001] The application belongs to the technical field of ship transportation, and in particular relates to a hatch cover 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 to provide a hatch cover seal...
