Abstract
The invention discloses a flat and straight angle joint with the four sides being covered. The flat and straight angle joint comprises an L-shaped polytetrafluoroethylene sponge core and rubber skin, and the four sides of the sponge core are covered with the rubber skin. The sponge core is provided with a body and a protruding part, wherein the section of the body is rectangular, and the protruding part protrudes downwards from the lower end of the body and is in the shape of an inverted isosceles trapezoid. The rubber skin comprises a first skin body, second skin bodies, third skin bodies and a fourth skin body, wherein the top surface of the body is covered with the first skin body, the side faces of the body are covered with the second skin bodies, the side faces of the protruding part are covered with the third skin bodies, and the bottom surface of the protruding part is covered with the fourth skin body. According to the flat and straight angle joint with the four sides being covered, 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, in particular to a four-sided covered flat right-angle joint. 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. [0004] The corner joints currently used for the sealing of ship cargo hatch covers are all foamed f...
