Abstract

The invention relates to the technical field of sealing rings, in particular to a sealing ring with high strength and low pressure change and a production process and an edge cutting device of the sealing ring. The sealing ring is prepared from the following raw materials in percentage by weight: 22 to 38 parts of low-temperature-resistant silicone rubber, 45 to 55 parts of modified polyurethane resin rubber, 12 to 34 parts of polycarbodiimide, 10 to 13 parts of white carbon black, 8 to 12 parts of graphite, 1.4 to 2.5 parts of TMTD, 3 to 6.3 parts of an emulsifier, 2.4 to 5.8 parts of an anti-aging agent, 2.6 to 4.8 parts of nano-zinc oxide, 0.05 to 0.1 part of triallyl isocyanurate, 7 to 9 parts of sodium phytate and 1.3 to 1.9 parts of glass fiber. By means of the scheme, the strength of the sealing ring is improved, low pressure change is achieved, the sealing effect of the sealing ring is satisfied, and the sealing requirement of equipment is met.

Description

technical field

[0001] The invention relates to the technical field of sealing rings, in particular to a high-strength and low-pressure variable sealing ring, a production process thereof, and an edge trimming device. Background technique

[0002] The sealing ring is a material or part that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents impurities such as external dust or water from intruding into the internal parts of the machine equipment. The sealing ring generally works under certain pressure and temperature conditions. Sealing rings with different structures and materials have different sealing effects under different conditions. However, once the sealing ring fails, it will directly affect the use of the equipment.

[0003] At present, the low strength and high pressure of the sealing ring make the sealing effect of the sealing ring unsatisfactory and cannot meet the sealing requirements of the equipment. At the same time, the ...
