Embodiment 1

[0037] A method for preparing a composite rubber material for a shock absorber, comprising primary rubber mixing and secondary rubber mixing, and the specific operation steps are as follows:

[0038] S1. Primary rubber mixing: Weigh 40 parts of modified natural rubber, 20 parts of butyl rubber, 30 parts of hydrogenated nitrile rubber, 5 parts of white carbon black, 10 parts of aromatic oil, 10 parts of zinc oxide, and 15 parts of magnesium, 2 parts of anti-aging agent 264, 5 parts of talc powder, and mix them in an internal mixer for rubber mixing. The temperature rises to 120°C, and the rubber mixing time is 4 minutes. After the rubber mixing is completed, the temperature of the rubber is lowered. The glue is produced below 100°C, and cooled to room temperature.

[0039] S2. Secondary rubber mixing: Put the rubber particles obtained from the first rubber mixing in the internal mixer again and add sulfur to carry out the second rubber mixing. The rubber mixing time is 2 minute...

Embodiment 2

[0041] A method for preparing a composite rubber material for a shock absorber, comprising primary rubber mixing and secondary rubber mixing, and the specific operation steps are as follows:

[0042] S1. Primary rubber mixing: Weigh 50 parts of modified natural rubber, 35 parts of butyl rubber, 40 parts of hydrogenated nitrile rubber, 10 parts of white carbon black, 20 parts of aromatic oil, 15 parts of zinc oxide, and 20 parts of magnesium, 8 parts of anti-aging agent 264, 10 parts of talcum powder, and mix them in an internal mixer for rubber mixing. The temperature rises to 140°C, and the rubber mixing time is 6 minutes. After the rubber mixing is completed, the temperature of the rubber is lowered. The glue is produced below 100°C, and cooled to room temperature.

[0043] S2. Secondary rubber mixing: Put the rubber particles obtained from the first rubber mixing in the internal mixer again and add sulfur to carry out the second rubber mixing. The rubber mixing time is cont...

Embodiment 3

[0045] A method for preparing a composite rubber material for a shock absorber, comprising primary rubber mixing and secondary rubber mixing, and the specific operation steps are as follows:

[0046] S1. Primary rubber mixing: Weigh 60 parts of modified natural rubber, 45 parts of butyl rubber, 45 parts of hydrogenated nitrile rubber, 15 parts of white carbon black, 25 parts of aromatic oil, 20 parts of zinc oxide, and 25 parts of magnesium, 15 parts of anti-aging agent 264, and 15 parts of talc powder were mixed and placed in an internal mixer for rubber mixing. The temperature rose to 160°C and the mixing time was 8 minutes. After the rubber mixing was completed, the temperature of the rubber was Cool down to below 100°C for gluing, and cool to room temperature.

[0047] S2. Secondary rubber mixing: put the rubber particles obtained from the first rubber mixing in the internal mixer again and add sulfur to carry out the second rubber mixing. The rubber mixing time is 4 minut...

Abstract

The invention discloses a composite rubber material for shock absorbers. The composite rubber material comprises the following raw materials in parts by weight: 40-60 parts of modified natural rubber, 20-45 parts of butyl rubber, 30-45 parts of hydrogenated nitrile-butadiene rubber, 5-15 parts of white carbon black, 10-25 parts of aromatic oil, 5-10 parts of sulfur, 10-20 parts of zinc oxide, 15-25 parts of flame retardant, 2-15 parts of anti-aging agent and 5-15 parts of filler. By using the modified natural rubber, butyl rubber and hydrogenated nitrile-butadiene rubber as the base materials, the reinforcing agent, vulcanizing agent, flame retardant and other aids are added to synergetically mill the rubber, so the formula is reasonable, thereby greatly enhancing the shock absorptivity of the composite rubber material. The composite rubber material for shock absorbers has the advantages of simple preparation technique and low cost investment, and the wear resistance and aging resistance of the rubber material are respectively improved.

Description

technical field [0001] The invention relates to the technical field of rubber shock absorbers, in particular to a composite rubber material for shock absorbers. Background technique [0002] With the rapid development of modern industry, vibration and noise have become serious problems in various fields: it will reduce the operating accuracy and affect product quality; it will shorten the life of products, making high-precision instruments unable to work normally; endangering safety, making equipment or structures Early damage; pollute the environment and affect human health. Therefore, the research and mastery of vibration control and noise control technology has become a major issue facing the industrial development of various countries. The most fundamental and best way to eliminate vibration and noise is to reduce or eliminate the vibration of the vibration source, but in fact it is impossible to completely eliminate the vibration of the vibration source, so other metho...
