Abstract
The invention relates to a soundproof material, in particular to a soundproof and explosionproof film and application thereof. The soundproof and explosionproof film consists of three layers, wherein the middle layer is PVC; and both lateral surface layers are PVB. An ultraviolet absorber, a hindered anime light stabilizer and an antioxidant are added into the middle layer and the lateral surface layers. The soundproof and explosionproof film is mainly applied to a glass interlayer of an automobile and a building, reduces external noise entering the automobile or a room and provides a comfortable environment for people. The three-layer structure of the soundproof and explosionproof film has more obvious effect than that of conventional single soundwave absorption or reflection. The soundproof and explosionproof film has the advantages of aging resistance, ultraviolet resistance, difficult water absorption, easy cleaning, and no pollution to environment and no harm to human bodies.
Description
Technical field
The present invention relates to acoustic material, be specifically related to a kind of soundproof and explosionproof film and application thereof.
Background technology
Along with human progress, the prosperity of science, noise pollution have become very important problem.Absorb noise, reduce the important topic that noise pollution has been related to the human society coordinated development.Along with going deep into of research, the material of various absorption sound waves produces thereupon.Its sound insulation principle all is to utilize when sound wave passes through certain object, and this object can absorb, reflect and weaken so that the continuation of partition sound wave is propagated, thereby reaches the effect of sound insulation.Acoustic material has many kinds, and at present common having is following several: building acoustic material, KTV acoustic material, finishing acoustic material, sound insulation damping material, damping shock dropping material, acoustic finishing material, decoration acoustical cotton plate, sound panel, sound-and-fire proof material etc.Thickness does not wait from 2.0mm to 4.0mm.
Conventional acoustic material volume is big, and soundproof effect is not good enough, and the acoustic material transparency of the present invention is good, can make film, and volume is little, and utilizes sound-absorbing and sound insulation double action, and soundproof effect is good.Conventional acoustic material has higher water imbibition, the suction easy mouldy corrosion in back, moreover common acoustic material surface is the absorption dust easily, difficult cleaning.And fire protecting performance, loss of properties on aging.There are indivedual acoustic materials to mix heavy metal, environment is polluted, also be unfavorable for health.Material of the present invention is made as matrix by PVB and PVC, has added various additives, does not contain heavy metal, after making laminated glass after the glass laminates with soundproof effect, and the deficiency of the above-mentioned common acoustic material of well having degraded.
Summary of the invention
At the defective of prior art, purpose of the present invention at first provides the good soundproof and explosionproof film of a kind of sound insulation value.
The present invention also aims to provide the concrete application of above-mentioned soundproof and explosionproof film.
Purpose of the present invention realizes by following technical scheme:
If not otherwise stated, all shares all represents with weight with percentage.
A kind of soundproof and explosionproof film is made of trilaminate material, and the intermediate layer is a polyvinyl chloride, and the both sides surface layer is a polyvinyl butyral resin; Be added with ultra-violet absorber, hindered amine as light stabilizer and antioxidant in described intermediate layer and the side facing respectively.
As preferably, the quality proportioning of described polyvinyl butyral resin and polyvinyl chloride is 5: 4-2: 1.

Can require to select different colouring agents according to concrete color in the soundproof and explosionproof film of the present invention.
Soundproof and explosionproof film of the present invention is mainly used in makes motor-vehicle glass window, building doors and windows etc., and concrete form is normally as the intermediate coat of laminated glass.
The preparation of soundproof and explosionproof film of the present invention is to adopt multi-layer co-extruded method, and is promptly earlier that each mixing of materials of intermediate layer and side facing is even, requires the change in concentration of each material in matrix to be no more than 4%, is no more than 3% especially, is no more than 1% especially again.After mixing, each layer material dropped into the multi-layer co-extruded film forming of extruder separately after, prolong film forming through the film roll-in again and get final product.The THICKNESS CONTROL of film is at 0.20mm to 0.90mm.
Soundproof and explosionproof film of the present invention is placed on two sheet glass intermediate layers is pressed into laminated glass.The thickness of every sheet glass is 2.0mm to 8.0mm.
Basic principle of the present invention is as follows:
The propagating characteristic of sound wave has determined macromolecular material can become the material of preferable absorption sound wave.The mode of propagation of sound wave is normally come Propagation of Energy with the form of compressional wave, but sound wave is propagated when arriving macromolecular chain, wherein part energy for a change the main chain of strand and side chain vibration and do work, the continuation that has weakened energy is propagated, thereby has reached the purpose that absorbs sound wave.Moreover on the surface of different medium, because the characteristic impedance difference, sound wave can reflect on dielectric surface, and the continuation that has also weakened sound wave is propagated.
Because acoustic material base material of the present invention is to have ultra high molecular weight polyethylene butyral and polyvinyl chloride, has higher internal damping characteristic, especially polyvinyl chloride and contain the bigger main chain of polarity, so its effect that absorbs sound wave is more obvious.Can absorb the sound wave of very big part, can reduce the coincidence effect that the glass resonant frequency causes significantly, strengthen the soundproof effect of glass.Secondly, the present invention normally uses as the interlayer film of bilayer or compound glass, in the material of different densities, sound wave energy reflects, especially between the interface of glass and interlayer, some can reflect sound wave at this, thereby can play the effect of sound insulation.
Compare with existing acoustic material, the present invention has following beneficial effect:
The present invention has the soundproof effect rupture pressure disc and has good soundproof effect, mainly is to be applied in the glass sandwich of automobile and building, reduces extraneous noise into the car or indoor, for people provide a comfortable environment.When sound wave from the external world when containing the laminated glass of this rupture pressure disc, after sound wave is reflected and absorbs, pass the sound that glass arrives opposite side at last and can weaken greatly.Effect than single absorption of tradition or reflective sound wave is more obvious, and material of the present invention is ageing-resistant, uvioresistant, be difficult for suction, cleaning, pollution-free to environment and human body easily, and these all are than traditional acoustic material advantage.
