Embodiment Construction

[0016] A high-elasticity and high-durability recycled rubber sealing ring, which is made from the following raw materials in parts by weight:

[0017] Regenerated rubber 60, EPDM rubber 5, diatomaceous earth 15, carbon nanofiber 5, rosin 4, butyl acrylate 2, 2,6-di-tert-butyl-p-cresol 0.5, sulfur 1, potassium persulfate 0.1, ten Sodium Dialkyl Sulfate 0.1, Diacetyl Tartaric Acid Mono-Diglyceride 1, Zinc Stearate 1, Palm Oil 2, Compound Additive 5;

[0018] Wherein the composite auxiliary agent is made of the following raw materials in parts by weight: tea seed oil 30, turpentine oil 3, glycerin 1, acetyl tributyl citrate 10, phytic acid 0.5, sorbitan monostearate 1, nano titanium dioxide 1. The preparation method of compound additives is to mix glycerin, phytic acid and sorbitan monostearate, stir at 80°C for 0.5h, then mix with the rest of the raw materials, stir at 50°C and 1000r / min for 1h, after cooling Instantly.

[0019] A preparation method of a high-elasticity and hi...

Abstract

The invention discloses a high-elasticity and high-durability regenerated rubber seal ring. The high-elasticity and high-durability regenerated rubber seal ring is prepared from raw materials in parts by weight as follows: 60-80 parts of regenerated rubber, 5-10 parts of ethylene-propylene-diene monomer rubber, 10-25 parts of diatomite, 5-10 parts of carbon nanofibers, 4-6 parts of rosin, 2-4 parts of butyl acrylate, 0.5-1 part of 2,6-di-tert-butyl-4-methylphenol, 1-2 parts of sulfur, 0.1-0.2 parts of potassium persulfate, 0.1-0.2 parts of sodium dodecyl sulfate, 1-2 parts of diacetyl tartaric acid ester of mono(di)glycerides, 1-2 parts of zinc stearate, 2-4 parts of palm oil and 5-10 parts of a compound aid. The regenerated rubber seal ring has an excellent mechanical property and use performance, good sealing performance and high overall performance, has high elasticity and durability, excellent flexing fatigue resistance and good elastic resilience and is long in service life and applicable to various mechanical devices.

Description

technical field [0001] The invention relates to the technical field of regenerated rubber, in particular to a high-elasticity and high-durability regenerated rubber sealing ring and a preparation method thereof. Background technique [0002] With the development of the economy, the demand for rubber is also increasing. At the same time, the disposal of waste rubber has also become one of the serious problems that people face. The degradation performance of rubber is poor, and it cannot be degraded naturally for a long time. A large amount of waste rubber not only poses a potential threat to the natural environment, but also wastes resources. One of the main ways of comprehensive utilization of waste rubber is to reprocess waste rubber to convert it into recycled rubber, so as to make the best use of everything and realize the development of circular economy. On the one hand, recycled rubber can replace rubber, alleviating the severe shortage of natural rubber; on the other...
