Abstract

The invention discloses a neoprene vibration reduction gasket material. The neoprene vibration reduction gasket material is prepared from neoprene, natural rubber, butyl rubber, carbon black N330, carbon black N660, organic modified rectorite, light calcium carbonate, nano-zinc oxide, aluminum hydroxide, red phosphorus master batch, a silane coupling agent KH570, barium stearate, an accelerant DM, an accelerant TMTM, sulfur, an anti-aging agent, an anti-ageing auxiliary, trioctyl trimellate, tributyl citrate and epoxy soybean butyl oleate. The neoprene vibration reduction gasket material has good abrasion-resistant and anti-vibration effects and excellent weather resistance, and is high in radial tensile strength, moderate in hardness, good in elasticity, long in service life and low in cost.

Description

Technical field [0001] The invention relates to the technical field of rubber materials, in particular to a neoprene damping gasket material. Background technique [0002] Vibration damping rubber products are often used in industrial production sectors such as railway vehicles, automobiles, and machinery. They absorb or reduce the vibration generated by the movement through the high damping effect of the product, so as to achieve the purpose of vibration reduction. Vibration damping rubber products are the most common ones. For example, when the car engine is working, the reciprocating movement of the piston in the cylinder, the combustion of fuel in the cylinder and the movement of other moving parts with the piston rod will cause the engine to vibrate violently. . If the engine is directly connected to the chassis, the chassis will also vibrate, which will affect the handling and comfort of the car. A damping gasket is installed between the automobile engine and the chassis ...

AI Technical Summary

Problems solved by technology

At present, vibration damping gaskets are greatly affected by the ambient climate because they are often exposed to the air.

At the same time, with the movement of the car, great pressure will be generated on the radial surface of the damping pad, which will easily cause the shock pad to deform, age or even crack, thereby affecting the damping effect and causing the vehicle to vibrate. Even frequent replacement of shock absorbing pads will increase the cost and cause inconvenience to users

Due to the heat generated by friction during use, rubber damping gaskets are prone to cracks, which is not conducive to the service life of rubber damping gaskets.

[0004] In the prior art, the material of vibration-damping gaskets is mostly made of natural rubber or styrene-butadiene rubber or cis-butadiene rubber. The hardness of the rubber is relatively high, the compressive stress is relatively large, and the shock-absorbing effect is poor. Some also use some reclaimed rubber, which is of poor quality

Because the above-mentioned rubber is not resistant to ozone and weather, and has poor compression set performance, poor aging resistance and weak vibration damping performance, it is difficult to apply to special working conditions.

For this reason, a rubber damping gasket that can solve the above problems is needed, and how to develop a rubber vibration damping gasket that has moderate hardness, high strength, high elongation, and ozone aging resistance. , weather aging resistance, and moderate compressive stress value, in order to improve the balance, comfort and durability of automobile driving, this has become a technical problem to be solved urgently in this technical field
