Problems solved by technology

If the quality of the seal is poor, it will cause loss and trouble if it is light, and it will cause serious accidents if it is serious
Especially in an environment with high working pressure, the seal ring bears a large load, and the seals are often damaged during the operation of the equipment. Some seals can only be used for 1 to 2 months, or even a shorter time. , it needs to be replaced, which brings troubles to the continuous production of the enterprise

Abstract

The invention discloses a hollowed-out lamination type sealing rubber material and a preparation method thereof. The rubber material comprises a main material and a skeleton. The main material comprises following components: nitrile rubber, acrylate rubber, epoxy resin, trimellitate, alumina, polyimide resin, white carbon black, an anti-aging agent, and sulfur. The skeleton is a graphene core, which has a plate structure. Multiple uniformly distributed lamination holes are arranged in the graphene core to form a hollowed-out structure; and the skeleton is arranged in the main material. The rubber material has a high structural strength and the lamination is firm.

Description

technical field [0001] The invention relates to a hollow-fitting sealing rubber material and a preparation method thereof. Background technique [0002] Sealing products are important basic components of all kinds of machinery, and almost all industrial sectors cannot do without it. The quality of the sealing element is directly related to the service life and operational reliability of the machine. If the quality of the seals is poor, it will cause loss and trouble if it is light, and it will cause serious accidents if it is serious. Especially in an environment with high working pressure, the seal ring bears a large load, and the seals are often damaged during the operation of the equipment. Some seals can only be used for 1 to 2 months, or even a shorter time. , it needs to be replaced, which brings troubles to the continuous production of the enterprise. Therefore, there is an urgent need for a rubber sealing material that can be used for a long period of time in a hi...
