Abstract

The invention discloses a flame-retardant and sound-insulating composite material, which is made of the following components in parts by weight: 80-100 parts of high-damping silicone rubber, 15-30 parts of silicon dioxide airgel, and benzoyl peroxide 1~2 parts, 80~100 parts of ABS resin, 20~30 parts of white carbon black, 4~6 parts of hydroxyl silicone oil, 23~38 parts of foam ceramic powder, 2~4 parts of light calcium carbonate, 3~7 parts of zinc borate , 5~8 parts of high vinyl silicone oil, 0.2~0.4 parts of silane coupling agent, 2~5 parts of vulcanizing agent. Also disclosed is a preparation method of a flame-retardant and sound-insulating composite material, comprising the following steps: step 1, weighing; step 2, mixing; step 3, vulcanization; step 4, plasticizing and forming. The flame-retardant and sound-insulating composite material provided by the invention has the characteristics of light weight, good mechanical properties, fire-proof and flame-retardant, and can effectively absorb low-frequency sound waves, and has a simple preparation method, low cost, and can be mass-produced.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a flame-retardant and sound-insulating composite 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 sound insulation materials are waterproof, fireproof, anti-aging, poor impact resistance, high energy ...
