Viton synthetic rubber joints

Abstract

The invention relates to a fluororubber synthetic rubber joint. The pipe wall of the fluororubber synthetic rubber joint successively comprises an outer rubber external layer, an outer rubber internal layer, a composite frame layer, an inner rubber internal layer and an inner rubber external layer from the outside to the inside. The raw material ratio of each layer of the pipe wall is also disclosed. The fluororubber synthetic rubber joint can resist a high temperature of 140 to 180 DEG C, is fatigue-resistant and oxidation-resistant and is excellent in mechanical performance. The layers are closely combined, the molecular chain is fully gummed, the intensity is high, and the elasticity is good.

Description

technical field

[0001] The invention relates to a rubber joint, in particular to a fluorine rubber synthetic rubber joint. Background technique

[0002] With the development of modern industry, the application of high-pressure pipelines is becoming more and more extensive. At present, the connectors of existing high-pressure pipelines are mainly divided into metal joints and rubber joints. Existing metal joints have strong compressive capacity, but they cannot absorb vibration and noise, and cannot compensate for displacement: when working, due to the large vibration generated during operation, it will cause damage to metal pipeline equipment, short service life, and emit a large noise. Noise, environmental pollution, and temperature changes will cause the pipes to expand with heat and contract with cold, but the metal joints cannot perform displacement compensation, and if the metal pipe joints are deflected or not concentric, the joints cannot be installed. Existing rubbe...
