Antibacterial sound insulation board and preparation method thereof

Abstract

The invention discloses an antibacterial sound insulation board, which is made from the following ingredients in parts by weight: 5-10 parts of nanometer titanium dioxide, 5-6 parts of nano silver particle, 40-80 parts of high damping silicone rubber, 40-50 parts of EPDM rubber, 15-30 parts of basalt fiber, 1-2 parts of benzoyl peroxide, 80-100 parts of EVA 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 mica powder, 0.3-0.5 part of zinc oxide, 2-4 parts of stearic acid, 1.2-1.8 parts of accelerator, 2-3 parts of antioxidant, 5-9 parts of bamboo charcoal particles, 3-7 parts of zinc borate, 5-8 parts of high vinyl silicone oil and 0.2-0.4 part of silane coupling agent. The antibacterial sound insulation board prepared by the invention has the antibacterial rate over 99%, the sound absorption coefficient over 0.8, the compressive strength >= 8 MPa, the breaking strength>= 25 MPa, and excellent flame retardancy.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an antibacterial sound-insulating board 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 consumption of mat...

AI Technical Summary

Problems solved by technology

[0003] Existing sound insulation materials are waterproof, fireproof, anti-aging, poor impact resistance, high energy consumption of materials is not environmentally friendly, pollute the environment after being discarded, cannot effectively absorb high, medium, and low frequency sound waves at the same time, and cannot block lower frequency sound waves, etc. question

Places with relatively high sound insulation requirements, such as theaters, KTV, hotels, etc., are usually closed spaces with poor ventilation, dense population, large flow of people, extensive sources of pollution, easy breeding of bacteria, and great health risks
