Abstract
The invention provides a high-efficiency acoustic anionic putty powder for a hidden flat acoustic speaker. The putty powder is prepared from the following components in percentage by volume: 10-70 percent of hollow glass beads, 5-30 percent of superfine triple superphosphate, 5-30 percent of ground calcium carbonate, 1-10 percent of hydroxypropyl methyl cellulose, 1-10 percent of white lignocellulose, 2-20 percent of sandwich rubber powder, 1-20 percent of redispersible latex powder, 1-10 percent of dry powdered polyvinyl alcohol and 1-5 percent of anionic powder. The high-efficiency acoustic anionic putty powder for a hidden flat acoustic speaker is small in density and light in weight, has small blockage and little absorption to acoustic wave, and can reduce attenuation to acoustic loudness.
Description
Technical field
The invention belongs to building material field, relate to specifically a kind of efficient acoustic negative ion putty powder of concealed flat panel loudspeaker.
Background technology
Concealed flat panel loudspeaker is in evolution in recent years, various formulas as the current market of putty material of its sounding body some all do not reach supporting with it requirement, the putty powder density of existing inner wall decoration is large, volume weight, seriously stop and absorb in a large number acoustic wave energy, sound intensity is reduced up to more than 10dB, and because original formula is taking water-ground limestone as main, due to the reason of deadweight and wave absorption, in having reduced sound loudness, the high frequency that sound equipment is sent has also carried out part and has absorbed, thereby while causing audition, there is the disappearance of part frequency band.For making up sound intensity needs, additionally strengthen a large amount of volumes, cause whole sound system efficiency poor efficiency, increase thermal value and the labile factor of system.
Summary of the invention
The object of the present invention is to provide a kind of efficient acoustic negative ion putty powder of concealed flat panel loudspeaker, the component that it contains following volume percent:
Hollow glass micropearl 10-70%, ultrafine heavy calcium 5-30%, water-ground limestone 5-30%, Vltra tears 1-10%, white wooden Mierocrystalline cellulose 1-10%, extra large rubber powder 2-20%, redispersable latex powder 1-20%, dry powder polyvinyl alcohol 1-10%, negative ion powder 1-5%;
Preferred each component ratio is:
Hollow glass micropearl 30-60%, ultrafine heavy calcium 5-15%, water-ground limestone 5-15%, Vltra tears 1-5%, white wooden Mierocrystalline cellulose 4-8%, extra large rubber powder 2-10%, redispersable latex powder 1-10%, dry powder polyvinyl alcohol 1-5%, negative ion powder 1-5%;
The efficient acoustic negative ion putty powder of a kind of concealed flat panel loudspeaker of the present invention, it can also contain one or more in the component of following volume percent:
Light calcium carbonate 5-30%, white cement 2-10%, ultrawhite ash calcium 1-5%, titanium dioxide 1-5%;
The ratio of preferred said components is:
Light calcium carbonate 10-25%, white cement 2-10%, ultrawhite ash calcium 1-4%, titanium dioxide 1-3%.
The present invention also provides the method for the efficient acoustic negative ion putty powder of preparing above-mentioned concealed flat panel loudspeaker:
Each component is mixed, stir.Can packaging and storing, when use, putty powder and water are stirred into cream smectic by the volume ratio of 2:1.
The efficient acoustic negative ion putty powder density of concealed flat panel loudspeaker of the present invention is little, lightweight, to sound wave stop little, absorb less, can reduce the decay to sound intensity, simultaneously less to the absorption of the each frequency range of audio frequency, particularly high frequency loss is little.For reaching sense of hearing sound equipment loudness needs, do not need additionally to strengthen too many volume, the efficiency of whole system and the graceful degree of increase sound are promoted, the Air quality simultaneously causing for reply audience rotation declines, moment keeps the pure and fresh of room air, reduce atmospheric pollution, the present invention in the putty material as a part for sounding body, has negative ion function for air purification in improvement.
Putty powder of the present invention also has following characteristic:
Lightweight, flexible elasticity is strong, acoustics loss is little, not crackle crack, dry linting not, non-scale, fine and smooth pure white, nondiscoloration, non-yellowing, moisture absorption is few, in water-tolerant, formula without any composition containing formaldehyde, high-environmental, the far infrared rays emissive power of anion material lean on the electromagnetic wave energy of far infrared rays to play antibacterial bacteriostatic effect, to eliminate the harm of various factors to human body, thereby the health of enhancement human body is object.Can eliminate peculiar smell in room, purify air.
Advantage of the present invention is as follows:
1, technical innovation, reaches acoustic technique requirement.
2, it is easy that raw material is easily purchased production.
3, cost performance is high, on the basis that meets quality, reduces costs.
4, application property is good, easy handling.
5, suitability is strong, except concealed flat panel loudspeaker uses, can be used for any indoor wall.
Embodiment
In the following example, hollow glass micropearl used is 3M company 25 types, and all the other components are common commercially available.
Embodiment 1
Take each component according to following volume percent respectively:
Above-mentioned raw materials is prepared according to volume percent, stirred and be prepared from, can packaging and storing, when use, putty powder and water are stirred into cream smectic by the volume ratio of 2:1.
Embodiment 2
By above-mentioned raw materials volume percent preparation, stir and be prepared from, can packaging and storing, when use, putty powder and water are stirred into cream smectic by the volume ratio of 2:1.
Embodiment 3
By above-mentioned raw materials volume percent preparation, stir and be prepared from, can packaging and storing, when use, putty powder and water are stirred into cream smectic by the volume ratio of 2:1.
Embodiment 4 acoustical testings
Use 2 of the A36 of Eogo Audio (Shanghai) Co., Ltd. type flat panel loudspeakers, a precious board inner wall putty of employing wall (control group) is coated with 3mm on flat panel loudspeaker, another adopts the formula of embodiment 2, putty powder and water are stirred into cream smectic by the volume ratio of 2:1, after modulating, (as experimental group) is coated with 3mm on flat panel loudspeaker, all fully after dry making an uproar, use professional loud speaker testing tool DASS to test until the putty on two flat panel loudspeakers.
In distance 1 meter of position of flat panel loudspeaker to be measured, record result as follows: at the middle register of 1KHZ, experimental group is than the high 5db of the loudness of control group, and in treble, the loudness of experimental group is far above the loudness of control group, and difference amplitude, up to 10db, promotes the audio of 3 times.Experimental result shows, it is quite obvious that experimental group promotes effect than control group to audio, and when actual audition, overall loudness occurs that than control group volume obviously increases, and high pitch is more clear bright.
