Description
Technical field
The present invention relates to protecting film technical field, be specifically related to a kind of noise reduction protecting film and preparation method thereof, particularly relate to
A kind of have the protecting film of silencing function, finished film and preparation method thereof.
Background technology
Along with developing rapidly of science and technology, the whole world has come into the epoch of high speed development, and urban construction adds increasingly
Hurry up, electronic product, automobile and skyscraper etc. are flooded with the life of people, and becoming increasingly abundant along with material life, people
More and more higher to the requirement of quality of life.
But the high speed development of modern city, also brings many negative impacts, environmental pollution is to affect people's life
The key factor of bioplasm amount, sound pollution, water pollute, atmospheric pollution and waste pollution be regarded as in world wide four main
Problem of environmental pollution.Sound pollution is that urbanite brings material impact among these, and sound pollution is also easy to
Ignored by people.
Noise refers to the sound that sounding body sends when doing random vibration.Sound is produced by the vibration of object, with the shape of ripple
Formula is propagated in certain medium (such as solid, liquid, gas).Usually said sound pollution refers to artificially to cause,
From the point of view of physiological point, every interference people's rest, study and work and the sound of the sound generation interference to be listened to you
Sound, the most unwanted sound, it is referred to as noise.When noise on human and surrounding have undesirable effect, it is formed for noise dirty
Dye.Since Industrial Revolution, the creation of various plant equipment and use, bring prosperity and progress to the mankind, but also produce simultaneously
More and more and the strongest noise.Audition not only can be caused damage by noise, moreover it is possible to induce multiple carcinogenic fatal
Disease, has also disturbed the life and work of people.Sound pollution can be divided into by the mechanical equivalent of light feature of sound source: gas disturbance produces
The electromagnetic noise that noise, the noise of liquid knockout generation and the electromagnetic action that the vibration of noise, solid produces produces.By sound
Frequency can be divided into: the high-frequency noise of<mid-frequency noise of the low-frequency noise of 400Hz, 400～1000Hz and>1000Hz.By sources lead
Traffic noise to be divided into, industrial noise, building noise and society's noise.
The noise of this industry and business is increasing, and people live in the environment that sound pollutes, right
The injury of human physiology and psychology all increasingly sharpens.
Thus, how can provide a kind of the most convenient but also not affect daily life, it is possible to for building construction and automobile
Etc. the product of aspect, help people to reduce noise, the injury of multi-angle many reductions noise pollution.Become the whole society altogether
With one of focus of attention.
