Abstract

The invention is suitable for the technical field of damping materials, and provides flame-retardant high-damping rubber and a preparation method of a damping shock pad thereof. Chlorinated butyl rubber CIIR1066, a POE elastomer, white carbon black, N990 type carbon black, 52 # liquid paraffin, decabromodiphenyl ethane, antimony trioxide, zinc borate, MCA, an anti-aging agent 1076, an anti-aging agent 2246, zinc oxide, stearic acid, resin and a DCP vulcanizing agent are adopted as ingredients to prepare the flame-retardant high-damping rubber. Through optimization design of components and contents thereof of the damping material, a rubber composition the flame retardance of which can reach UL94-V0 level, and which has a wide temperature range and high damping performance can be obtained. The damping material is wide in use temperature range, high in damping factor, good in flame retardance and aging resistance and good in mechanical property.

Description

technical field [0001] The invention belongs to the technical field of damping materials, and in particular relates to a preparation method of a flame-retardant high-damping rubber and a damping and shock absorbing pad. Background technique [0002] Due to its special viscoelasticity, the material can produce large internal friction (ie high damping), and has a light specific gravity and is easy to process, so it has become the most researched and most widely used damping material. Rubber damping materials have been widely used in many fields such as high-speed rail, aerospace, naval ships, automobiles and electronic appliances. Especially in various servers, computers, workstations, switches and other IT equipment, the data storage system causes the vibration and noise of the cabinet due to the rotation of the fan, which seriously affects the service life of the hard disk. The demand for high-efficiency damping and vibration reduction products is very urgent. The applicati...
