Problems solved by technology

Commonly used sound-absorbing cotton includes glass fiber sound-absorbing cotton and polyester fiber sound-absorbing cotton. Glass fiber sound-absorbing cotton is poor in environmental protection, and its raw materials contain harmful substances. It is easy to cause itching when it touches human skin, and it is not convenient for construction.

Embodiment Construction

[0014] A high-impact sound-absorbing cotton is made from the following raw materials in parts by weight:

[0015] Barium stearate 1, sodium xylene sulfonate 0.5, zircon powder 5, silicon carbide 3, ethylene bisstearamide 1, polypropylene 80, styrene 2, epoxy butyl furfurate 1, butyl methacrylate Ester 3, polyethylene glycol 1, azobisisobutyronitrile 0.05, castor oil 0.5, functional powder 3;

[0016] The functional powder is made of the following raw materials in parts by weight: tourmaline powder 5, medical stone powder 3, nano-titanium dioxide 2, cerium oxide 1, hydroxypropyl methylcellulose 1, polyvinyl alcohol 1, water 40; functional powder The preparation method is to first add hydroxypropyl methylcellulose and polyvinyl alcohol into water and stir at 85°C for 0.5h, then add the rest of the raw materials and continue to stir for 1h, filter and dry completely, then calcinate at 700°C for 1h, cool and grind Evenly, that is.

[0017] A preparation method of high-impact sou...

Abstract

The invention discloses acoustic wool with high impact resistance. The acoustic wool is prepared from, by weight, 1-2 parts of barium stearate, 0.5-1 part of sodium xylene sulfonate, 5-10 parts of zircon powder, 3-5 parts of silicon carbide, 1-2 parts of ethylene bis stearamide, 80-100 parts of polypropylene, 2-4 parts of styrene, 1-2 parts of epoxy rice bran oleic acid butyl ester, 3-5 parts of butyl methacrylate, 1-2 parts of polyethylene glycol, 0.05-0.1 part of azodiisobutyronitrile, 0.5-1 part of castor oil and 3-5 parts of functional powder. The acoustic wool is good in sound absorption effect and mechanical performance, high in durability, high in impact resistance, less prone to deformation, good in processing performance, capable of absorbing harmful substances in air, effectively purifying the air and protecting human health, high in comprehensive value and high in practicality.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing materials, in particular to a high-impact-resistant sound-absorbing cotton and a preparation method thereof. Background technique [0002] Due to the rapid development of the economy, the number and types of noise sources are increasing. Noise pollution has penetrated into all areas of people's work and life. Noise has become one of the most serious and widespread pollution affecting people's lives. With the increasing awareness of environmental protection, the problem of noise pollution has been paid more and more attention. In order to find a solution and ensure the normal progress of people's life and learning activities, it is necessary to continuously develop new materials that can control noise hazards. [0003] Sound-absorbing cotton is a porous sound-absorbing material. When the sound passes through the channel, it is reflected multiple times in the material, and the sound energy ...
