Abstract
The invention discloses a rubber shock absorption pad for an engine and relates to the technical field of rubber products. The rubber shock absorption pad is prepared from the following raw materials in parts by weight: 40-60 parts of deproteinized 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 an accelerant and 3-5 parts of an antioxidant, wherein the carbon fibers are soaked in a silane coupling agent and dried for use. The rubber shock absorption pad solves problems of high possibility of fatigue and poor impact resistance and tear resistance of an existing rubber shock absorption pad for the engine.
Description
Technical field
The present invention relates to rubber item technical field, especially a kind of Rubber shock-absorbing pad for engineering machinery engine.
Background technology
Engine is the primary oscillation source of engineering machinery, and it not only can bring larger noise, and can affect reliability and the work-ing life of engineering machinery, therefore must adopt the transmission of certain methods separating vibration and absorb the impact vibrated and cause.Cushion blocking is a kind of modal auxiliary damping element, and it is arranged on engine and engineering machinery usually, and its structure is simple, easy to manufacture, cost is low, can meet most damping requirements.The material of engine cushion blocking all adopts rubber mostly, and the snappiness of rubber makes it have good effectiveness in vibration suppression.But, existing engine Rubber shock-absorbing pad, fatiguability, shock resistance and tear resistance poor, in use for some time, effectiveness in vibration suppression just significantly reduces, and the work-ing life of cushion blocking is shorter.
Summary of the invention
The object of this invention is to provide a kind of engine Rubber shock-absorbing pad, this cushion blocking can solve the fatiguability of available engine Rubber shock-absorbing pad existence and the problem of shock resistance and tear resistance difference.
In order to solve the problem, the technical solution used in the present invention is: this engine Rubber shock-absorbing pad is made up of the raw material of following masses number: DPNR 40 ~ 60 parts, terpolymer EP rubber 20 ~ 40 parts, 20 ~ 30 parts, carbon fiber, white carbon black 20 ~ 25 parts, stearic acid 2 ~ 3 parts, 4 ~ 6 parts, zinc oxide, 2 ~ 4 parts, sulphur, promotor 1.5 ~ 2.5 parts, 3 ~ 5 parts, anti-aging agent; After described carbon fiber floods in silane coupling agent, dry and use.
In the technical scheme of above-mentioned engine Rubber shock-absorbing pad, technical scheme can also be more specifically: DPNR 50 parts, terpolymer EP rubber 38 parts, 25 parts, carbon fiber, white carbon black 20 parts, stearic acid 3 parts, 5 parts, zinc oxide, 3 parts, sulphur, promotor 2 parts, 4 parts, anti-aging agent.
Further, described promotor is dithio tetrabutyl thiuram.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, by adopting DPNR, terpolymer EP rubber and carbon fiber, effectively improve the shock-resistance of cushion blocking, wear resistance and tear strength, damping effect is lasting, and work-ing life increases.
2, white carbon black is used can to improve shock resistance effect further.
