Embodiment 1

[0018] The preparation method of rubber damping pad for engine in the present embodiment comprises the following steps:

[0019] A. Weigh the raw materials according to the following parts by mass: 40 parts of deproteinized natural rubber, 20 parts of EPDM rubber, 30 parts of carbon fiber, 22 parts of white carbon black, 2 parts of stearic acid, 4 parts of zinc oxide, 2 parts of sulfur part, 1.5 parts of accelerator, 3 parts of anti-aging agent; Wherein, accelerator is dithiotetrabutylthiuram;

[0020] B. Immerse the carbon fiber in the silane coupling agent for 5 minutes, then dry it for use;

[0021] C. Add the deproteinized natural rubber and EPDM rubber into the open mill and knead with the roll temperature at 60°C. After the rubber material is wrapped with the roll, add carbon fiber, white carbon black, stearic acid, and zinc oxide in two and anti-aging agent, mixed for 3 minutes each time, finally added sulfur and accelerator and mixed for 10 minutes, and left to stand ...

Embodiment 2

[0026] The preparation method of rubber damping pad for engine in the present embodiment comprises the following steps:

[0027] A. Weigh the raw materials according to the following parts by mass for later use: 50 parts of deproteinized natural rubber, 38 parts of EPDM rubber, 25 parts of carbon fiber, 20 parts of white carbon black, 3 parts of stearic acid, 5 parts of zinc oxide, and 3 parts of sulfur 2 parts, 2 parts of accelerator, 4 parts of anti-aging agent; Wherein, accelerator is dithiotetrabutylthiuram;

Abstract

The invention discloses a preparation method of a rubber shock pad for an engine, and relates to the technical field of rubber products. The preparation method comprises the following steps: weighing the following raw materials in parts by weight: 40-60 parts of deproteinization natural rubber, 20-40 parts of ethylene propylene diene monomer, 20-30 parts of carbon fibers, 20-25 parts of white carbon black, 2-3 parts of stearic acid, 4-6 parts of zinc oxide, 2-4 parts of sulfur, 1.5-2.5 parts of accelerant and 3-5 parts of anti-aging agent; steeping the carbon fibers in a silane coupling agent, and then drying; adding the two types of rubber to an open mill, mixing, after covering rollers with a sizing material, adding the carbon fibers, the white carbon black, the stearic acid, the zinc oxide and the anti-aging agent at twice, finally adding the sulfur and the accelerant for mixing, and standing for 24 hours after forming sheets; and putting a rubber compound on a plate vulcanizing machine so as to vulcanize, and then trimming to obtain the required product. The preparation method can be used for solving the problem that the traditional rubber shock pad for the engine is likely to fatigue and has poor impact resistance and tear resistance.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a rubber shock-absorbing pad used for engineering machinery engines. Background technique [0002] The engine is the main vibration source of construction machinery. It will not only bring a lot of noise, but also affect the reliability and service life of construction machinery. Therefore, some methods must be used to isolate the transmission of vibration and absorb the impact caused by vibration. Shock absorbing pad is the most common auxiliary damping element. It is usually installed in engines and construction machinery. It has a simple structure, easy manufacture, and low cost, and can meet most of the vibration damping requirements. Most of the engine shock pads are made of rubber, and the high elasticity of rubber makes it have a good vibration damping effect. However, the existing rubber damping pads for engines are prone to fatigue, have poor impact resistance a...
