Abstract

The invention discloses a sound insulating material. The sound insulating material is prepared from the following components in parts by weight: 60 to 80 parts of high damping silicone rubber, 4 to 6parts of hydroxy silicone oil, 12 to 25 parts of silica aerogel, 1 to 2 parts of dicumyl peroxide, 60 to 80 parts of PP resin, 18 to 25 parts of turpentine, 20 to 30 parts of white carbon black, 23 to38 parts of foam ceramic powder, 2 to 4 parts of barium sulfate, 0.4 to 0.9 part of sodium stearate, 0.3 to 0.5 part of active zinc oxide, 6 to 10 parts of diatomaceous earth, 3 to 7 parts of zinc borate, 5 to 8 parts of high vinyl silicone oil, 0.2 to 0.4 part of aluminate coupling agent, 3 to 5 parts of vulcanizing agent, and 1.4 to 1.9 parts of accelerator. The invention also discloses a preparation method of the sound insulating material. The sound insulating material provided by the invention has the characteristics of light weight, good mechanical performance, fire retarding, and effectively absorbing low-frequency sound waves, and has the advantages of simple preparation method, low cost and mass production.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a sound-insulating material and a preparation method thereof. Background technique [0002] Noise pollution has become a global environmental problem and has seriously affected people's production and life. The demand for sound-absorbing materials in modern society is increasing, and the performance requirements for sound-absorbing materials are also getting higher and higher. Existing sound-absorbing materials have good sound-absorbing performance in the high-frequency band of noise, but poor sound-absorbing performance in the low-frequency band. How to improve the sound-absorbing performance of sound-absorbing materials in the low-frequency range has become a difficult point in the field of sound-absorbing materials research. [0003] Existing decorative materials have waterproof, fireproof, anti-aging, poor impact resistance, high energy consumption of materials, are not e...
