Abstract

The invention relates to a polysiloxane microsphere damping chlorinated butyl rubber composite material and a preparation method thereof. The polysiloxane microsphere damping chlorinated butyl rubber composite material is prepared from the following components of 100 parts of chlorinated butyl rubber, 1 to 3 parts of vulcanizing agent, 1 to 3 parts of accelerant, 2 to 4 parts of stearic acid, 1 to 2 parts of nanometer zinc oxide, 2 to 4 parts of anti-aging agent, 1 to 3 parts of light-weight magnesium oxide, and 5 to 20 parts of polysiloxane microsphere; the components are added into a mixing mill to mix according to a formula, so as to obtain the polysiloxane microsphere damping chlorinated butyl rubber composite material. Compared with the prior art, the polysiloxane microsphere damping chlorinated butyl rubber composite material has the advantages that the chlorinated butyl rubber is modified by the polysiloxane microsphere, the damping temperature range is obviously widened, and the damping property, mechanic property and heat conduction property are improved.

Description

technical field [0001] The invention relates to a polysiloxane composite material, in particular to a polysiloxane microsphere damping chlorinated butyl rubber composite material and a preparation method thereof. Background technique [0002] The rapid development of modern industry makes mechanical equipment tend to be high-speed, and a series of problems related to machinery such as vibration and noise also arise. These problems not only accelerate the fatigue damage of the mechanical structure, shorten its service life, but also to a certain extent Will pollute the environment and endanger human health. Therefore, it is very important to develop high-efficiency damping materials with excellent performance, improve their damping and vibration reduction effects, and improve the operating environment of mechanical equipment. [0003] Chlorobutyl rubber is widely used in shock absorption, damping and other fields. With the development of cutting-edge technologies such as th...
