Abstract

The invention discloses a pressure-resistant waterproof rubber sealing ring and a preparation method thereof, and belongs to the technical field of sealing rings. According to the pressure-resistant waterproof rubber sealing ring and the preparation method thereof, the comprehensive performance of rubber can be improved by improving raw materials, meanwhile, a pressure-resistant bag is introduced and embedded between working faces, and the pressure in the working direction is sensed through a pair of force contact pieces. The pressure is fed back to a feedback air bag in the middle through a force transmission rod, meanwhile, the change of magnetic fluid in a magnetic control bag is controlled through the deformation of the feedback air bag, and when the sealing ring slightly deforms due to the too large pressure, the feedback air bag forms an extrusion effect on the magnetic fluid diffusing towards the edge. Further, the magnetic field shielding effect of the magnetic fluid on a pair of repulsive magnets is weakened, the magnetic repulsive effect between the pair of repulsive magnets is enhanced, meanwhile, external pressure is resisted to assist the sealing ring in shape restoring, the good sealing performance is restored, compression resistance protection is conducted on the sealing ring, and meanwhile the service life of the sealing ring can be remarkably prolonged.

Description

technical field

[0001] The invention relates to the technical field of sealing rings, in particular to a pressure-resistant waterproof rubber sealing ring and a preparation method thereof. Background technique

[0002] Rubber (Rubber) refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight, greater than hundreds of thousands.

[0003] Rubber is divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life.

[0004] Natural rubber has high tensile s...
