Preparation method of seal ring aging-resistant rubber material

Abstract

The invention discloses a preparation method of a seal ring aging-resistant rubber material. The preparation method comprises the following steps of orderly adding 90-120 weight parts of chlorinated polyethylene, 10-15 weight parts of leadoxide, 1-2 weight parts of sodium stearate, 1-2 weight parts of an antiager RD, 2.5-5 weight parts of a vulcanizing agent and 1.5-3 parts of a vulcanizing assistant into an internal mixer, adding sheet-shaped intermediate materials into the internal mixer, adding the vulcanizing agent into the internal mixer, carrying out mixing for 1min, and carrying out compressing by a tablet compressing machine to obtain a finished product.

Description

technical field [0001] The invention relates to a method for manufacturing a sealing ring material. Background technique [0002] In industrial production, the pipe connection is generally connected by flanges, and rubber gaskets are added between flanges for sealing. Some containers and equipment use rubber gaskets as sealing gaskets. Most of these rubber gaskets and sealing gaskets are made of natural rubber, These ordinary pad materials generally have poor temperature resistance, poor ozone aging resistance, and acid resistance, so they are easy to age and corrode, especially in acidic media. In the chemical industry, it is more common to transport acid and acidic materials through pipelines, and use containers and equipment to store and use acidic materials. In this way, if the maintenance and replacement are not timely, the sealing gasket is easy to be leaked due to corrosion and aging. , causing the leakage of materials, which not only wastes raw materials, but also c...

Problems solved by technology

[0002] In industrial production, the pipe connection is generally connected by flanges, and rubber gaskets are added between flanges for sealing. Some containers and equipment use rubber gaskets as sealing gaskets. Most of these rubber gaskets and sealing gaskets are made of natural rubber, It is processed from styrene-butadiene rubber, etc. These ordinary rubber pad materials generally have poor temperature resistance, poor ozone aging resistance, and acid resistance, so they are easy to age and be corroded, especially in acidic media.

In the chemical industry, it is more common to transport acid and acidic materials through pipelines, and use containers and equipment to store and use acidic materials. In this way, if the maintenance and replacement are not timely, the sealing gasket is easy to be leaked due to corrosion and aging. , causing the leakage of materials, which not only wastes raw materials, but also corrodes the equipment, and even causes parking in severe cases.
