Abstract
The utility model provides a inhale sound and eliminate sound multi-structure polymer composite, includes sound-proof material, noise-proof material and sound-absorbing material, three kinds of materials superpose together, and noise-proof material is located the centre, and noise-proof material and sound-absorbing material are porous material, and sound-absorbing material has the uneven surface of fluctuation. The sound insulation material has the function of gluing and can be conveniently glued with various walls; when sound waves enter the silencing material, the sound waves rub against countless mutually communicated hole walls, so that sound energy is converted into heat energy to be eliminated, and the silencing effect is achieved. The structure of the sound-absorbing material increases the contact area between the sound-absorbing material and sound waves, and has better sound-absorbing effect.
Description
Technical field
The utility model belongs to a kind of building materials, especially refers to a kind of compound substance that can sound insulation.
Background technology
Existing sound-absorbing, deadener all are the glass fibre cotton of single structure or sponge etc., sound-proof material also all is the sheet material of single structure, and as medium density fiberboard, calcium silicate board with microporous, steel plate etc., sound-absorbing, noise elimination effect are very undesirable, also do not possess decoration functions.
The utility model content
A purpose of the present utility model is to solve weak point of the prior art, and a kind of sound-absorbing noise elimination sound-proof material that is composited with trilaminate material is provided.
For achieving the above object, many structuring polymers of sound-absorbing noise elimination sound insulation compound substance of the present utility model comprises sound-proof material, deadener and acoustical material, described three kinds of materials are superimposed, in the middle of deadener is positioned at, deadener and acoustical material are porosint, and acoustical material has up-and-down surface.
Preferably, the outside surface of sound-proof material has viscosity.
Preferably, acoustical material is made up of a plurality of cones.
Preferably, acoustical material is made up of a plurality of stage bodies.
Preferably, deadener and acoustical material are melamine resin foam.
Sound-proof material possesses gluing function, can stick together with all kinds of walling glues easily; When sound wave enters into deadener and the countless hole wall frictions that is interconnected, make acoustic energy be converted into heat energy and digest, thereby play the noise elimination effect.The structure of acoustical material makes the contact area of it and sound wave increase, and has better sound-absorbing effect.
The utility model also has excellent flame-retardant performance and thermal insulation, can be widely used in fields such as engineering construction acoustic finishing, noise abatement, Aero-Space, boats and ships submarine, machinery, medical treatment, environmental protection, electromechanical equipment, automobile, metallurgy, household electrical appliance damping, noise reduction, sound-absorbing.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model first embodiment.
Fig. 2 is the synoptic diagram of the utility model second embodiment.
Embodiment
Fig. 1 is the synoptic diagram of the utility model first embodiment, with reference to Fig. 1, many structuring polymers of sound-absorbing noise elimination sound insulation compound substance of the present utility model comprises sound-proof material 1, deadener 2 and acoustical material 3, described three kinds of materials stack is glued together, and in the middle of deadener 2 was positioned at, deadener 2 had countless tiny holes, hole interconnects, acoustical material 3 can be made up of a plurality of cones, also can be made up of a plurality of stage bodies as shown in Figure 2.The outside surface of sound-proof material 1 has viscosity, is convenient to be connected with all kinds of bodies of wall.
Sound-proof material can adopt materials such as pitch, iron filings, cement to be mixed and processed.
Acoustical material and deadener can adopt melamine resin foam, possess following characteristic:
1. superpower sound absorption qualities: it is up to the percentage of open area more than 99%, and links to each other with filament fully, makes sound wave energy enter the deep layer of material easily and effectively and the vibration that changes grid into is consumed and sponges, and eliminates radioactive wave effectively.
2. high flame resistance: need not add fire retardant and can reach German DIN 4102 B1 levels, U.S. UL94-96 V0 level high flame retardant material standard.Thereby form fine and close coke layer retardance burning on the surface of burner body behind the contact naked light, no drip, no toxic smoke puts out certainly from fire.
3. good thermal and insulating performance: it is up to the percentage of open area more than 99%, and the three dimensional network structure system is effectively blocked the convection heat transfer' heat-transfer by convection of air, therefore has good heat insulation effect.
4. resistance to elevated temperatures: suitable long-term work does not have below 400 ℃ and decomposes and metaboly under 150～200 ℃ of conditions of work Celsius.
5. lightweight: product unit weight is at every cubic metre of 4-12 kilogram, is the lightest sound-absorbing noise elimination sound-proof material at present, saves the energy.
6. the feature of environmental protection: non-toxic sanitary safety, chemical constitution that it is stable and cross-linking system make it have unique chemical stability, anti-highly basic, weak acid satisfy the environmental protection safety standard of country about noise reduction fields such as interior decoration, daily, industrial, testing laboratory and the vehicles fully.
7. use industry extensive: to can be used for building, vehicle, plant equipment, industries such as air-conditioning unit and war products.
If acoustical material is made up of a plurality of cones, the height of cone can be set according to the concrete requirement in place.Can adopt following method to calculate the height of cone:
If requiring the anechoic room cutoff frequency is Hz for f. unit, according to 1/4 wavelength theory:
------λ is a wavelength to height L=(1/4) x λ, and unit is m;
=(1/4) * (C/f)---C is the velocity of sound;
=(1/4) * (340/f)---wherein 340m/s is the aerial velocity of propagation of sound wave.
