From an environmental protection perspective, this material pays attention to environmental protection principles during its design and production process, which helps reduce the impact on the environment. With the improvement of global awareness of environmental protection, the demand for environmentally friendly materials is also growing. As an environmentally friendly material, butyl damping and vibration reduction film can meet this demand and contribute to environmental protection.

[0003] Currently, butyl rubber vibration damping pads are mostly used in automobiles, but the vibration damping performance of the existing damping pads needs to be improved;

[0004] The existing patent (Announcement No.: CN212889329U) is an environmentally friendly damping and vibration reduction pad. This utility model is an environmentally friendly damping and vibration reduction pad that adopts odorless, environmentally friendly, high-purity butyl rubber with an environmentally friendly polymer material formula. The surface is attached with waterproof paper for anti-oxidation, so that the product is stable in nature and does not flow at high temperatures. It can effectively suppress the vibration of the chassis, roof, door trunk, etc. of the car, and effectively suppress various types of noise to protect the car structure; and the high-purity environmentally friendly butyl rubber is almost in its original state, so it is more environmentally friendly. The high-purity environmentally friendly butyl rubber in this utility model can eliminate or slow down the adverse consequences of vibration, bring people a comfortable riding environment, and can buffer the pressure on the car's vibration reduction system caused by road bumps, and reduce the probability of damage to the car's vibration reduction system.
