Description
Technical field
The present invention relates to a kind of lightweight regenerated resources sound-absorbing materials and preparation method thereof, belong to noise pollution Treatment process neck
Domain.
Background technique
Noise pollution, water pollution and atmosphere pollution are listed in the pollution greatly of the whole world three.With industrial, transportation fast
Speed development, noise pollution are on the rise.Noise not only endangers the auditory system of people, but also can accelerate building, mechanical structure
Aging, influence the precision and service life of equipment and instrument.
In recent years, with the continuous improvement of people's quality of the life and being increasingly enhanced for environmental consciousness, to living environment
It is required that also stepping up, the control problem of noise has caused national governments and the most attention of scientific worker.Sound-absorbing material can
Set about administering noise pollution in terms of protecting three with the source, communication process and the terminal victim that generate from noise, is to answer
With to noise pollution the most effective means.Sound-absorbing material is mostly loose porous material, such as mineral wool, mineral wool, polyurethane
Foamed plastics etc., sound absorbing mechanism is the hole that sound wave gos deep into material, and hole is mostly the internal open pore to interpenetrate, by
Air molecule friction and viscosity resistance, and fiber fines is made to make mechanical oscillation, so that sound is enable to be changed into thermal energy, it is this kind of porous
The acoustic absorptivity of property sound-absorbing material, is generally gradually increased from low to high, thus to the sound absorbing effects of high frequency and intermediate frequency compared with
It is good.Traditional sound-absorbing cotton material sound-absorbing effect is preferable, but non-degradable, cannot independently be used as bearing structure material, fire line
Poor, the poor waterproof properties of energy, and manufacturing cost is high.
The research and development of some sound-absorbing materials with flame retardant property are had existed in currently available technology.Domestic patent
CN101807394Y discloses a kind of layered sound-absorbing material that micro nanometer fiber is compound, which is by one or more while to contain
Combination is overlapped mutually by the sound absorbing layer that 50~900nm and 2~800 μm of fiber forms, by the micro-nano for adjusting different layer materials
Rice fibre fractionation, thickness, bulk density and functional filler come adjust integral material sound-absorbing and the performances such as fire-retardant, but should
The sound-absorbing material complex manufacturing technology and higher cost of patent.
