Abstract

The invention relates to a highly flame-retardant destatic type butyl rubber composite damping material and a preparation method thereof. By using brominated butyl rubber as the composite damping basematerial and by the utilization of high-temperature resistant and flame-retardant property of polytetrafluoroethylene powder, the product has extremely high flame retardance. Meanwhile, by adding carbon nanotube for coating ceramic powder, the product has the destaticizing effect. Then, carbon black, polyisobutylene, petroleum resin, light calcium carbonate and naphthenic oil are subjected to mixing. After uniform mixing, tabletting is carried out. Finally, the tabletting product is compounded with a bound layer Kevlar and an isolated layer release paper in a tablet press to obtain the damping material for vehicles.

Description

technical field [0001] The invention belongs to the field of damping materials, and relates to restraint damping materials for automobiles, in particular to a high flame-retardant and static-removing butyl rubber composite damping material and a preparation method thereof. [0002] technical background [0003] With the rapid development of the automobile industry, people have put forward higher requirements for the comfort of automobiles, especially the research on the damping system, which can effectively reduce the amplitude of the rapid attenuation of vibration, play a role in reducing vibration, and improve the driving of automobiles. Ride and handling stability. Damping materials can absorb vibrational mechanical energy and convert them into functional materials that lose thermal energy. Among them, polymer damping materials are the most studied and widely used type of damping materials. [0004] At present, most of the vibration reduction and damping parts used in th...
