Abstract
The invention provides the efficient acoustic powder of lacquer putty for use on of a kind of concealed flat panel loudspeaker, it is containing, for example the component of lower volume percentage ratio: hollow glass micropearl 10-70%, ultrafine heavy calcium 5-30%, ground calcium carbonate 5-30%, hydroxypropyl methyl cellulose 1-10%, white wooden cellulose 1-10%, sea rubber powder 2-20%, redispersable latex powder 1-20%, dry powder polyvinyl alcohol 1-10%.The efficient acoustic powder of lacquer putty for use on density of the concealed flat panel loudspeaker of the present invention is little, lightweight, sound wave stopping, little, absorption is lacked, can reduce the decay to sound intensity.
Description
Technical field
The invention belongs to building material field, more particularly to the efficient acoustic powder of lacquer putty for use on of a kind of concealed flat panel loudspeaker.
Background technology
Concealed flat panel loudspeaker is in evolution in recent years, various formula as the current market of putty material of its sounding body some all do not reach matched requirement, the powder of lacquer putty for use on density of existing inner wall decoration is big, volume weight, serious stop also absorbs acoustic wave energy in a large number, sound intensity is made to reduce up to more than 10dB, and owing to original formula is based on ground calcium carbonate, reason due to deadweight and wave absorption, while reducing sound loudness, the high frequency sent by sound equipment has been also carried out part and has absorbed, thus occurring the disappearance of part frequency band when causing audition.For making up sound intensity needs, to additionally strengthen a large amount of volume, cause whole sound system efficiency poor efficiency, add caloric value and the unstable factor of system.
Summary of the invention
It is an object of the invention to provide the efficient acoustic powder of lacquer putty for use on of a kind of concealed flat panel loudspeaker, it is containing, for example the component of lower volume percentage ratio:
Hollow glass micropearl 10-70%, ultrafine heavy calcium 5-30%, ground calcium carbonate 5-30%, hydroxypropyl methyl cellulose 1-10%, white wooden cellulose 1-10%, sea rubber powder 2-20%, redispersable latex powder 1-20%, dry powder polyvinyl alcohol 1-10%；
The percent by volume of preferred each component is:
Hollow glass micropearl 30-60%, ultrafine heavy calcium 5-15%, ground calcium carbonate 5-15%, hydroxypropyl methyl cellulose 1-5%, white wooden cellulose 4-8%, sea rubber powder 2-10%, redispersable latex powder 1-10%, dry powder polyvinyl alcohol 1-5%；
A kind of efficient acoustic powder of lacquer putty for use on of the concealed flat panel loudspeaker of the present invention, they can also containing, for example one or more in the component of lower volume percentage ratio:
Precipitated calcium carbonate 5-30%, white cement 2-10%, ultrawhite ash calcium 1-5%, titanium dioxide 1-5%；
The ratio of preferred said components is:
Precipitated calcium carbonate 10-25%, white cement 2-10%, ultrawhite ash calcium 1-4%, titanium dioxide 1-3%.
The method that present invention also offers the efficient acoustic powder of lacquer putty for use on preparing above-mentioned concealed flat panel loudspeaker:
Each component is mixed, stirs.Can packaging and storing, during use, powder of lacquer putty for use on and water are stirred into cream smectic by the volume ratio of 2:1.
The efficient acoustic powder of lacquer putty for use on density of the concealed flat panel loudspeaker of the present invention is little, lightweight, sound wave stopping, little, absorption is lacked, can reduce the decay to sound intensity, and simultaneously that the absorption of each frequency range of audio frequency is less, particularly high frequency loss is little.For reaching audition sound equipment loudness needs, it is not necessary to the too many volume of extra increasing, improve the efficiency of whole system and increase the graceful degree of sound.
Powder of lacquer putty for use on of the present invention also has the property that
Elasticity lightweight, flexible is strong, acoustic losses is little, not crackle crack, not dry linting, non-scale, fine and smooth pure white, invariant color, non-yellowing, moisture absorption is few, without any composition containing formaldehyde, high-environmental in water-tolerant, formula.
Advantage of the present invention is as follows:
1, technically innovate, reach acoustic technique requirement.
2, production simplicity easily purchased by raw material.
3, cost performance is high, reduces cost on the basis meet quality.
4, application property is good, it is easy to operation.
5, the suitability is strong, except using except concealed flat panel loudspeaker, can be used for any indoor wall.
Detailed description of the invention
Hollow glass micropearl used in the following example is 3M company 25 type, and all the other components are common commercially available.
Embodiment 1
Each component is weighed respectively according to following percent by volume:
Above-mentioned raw materials is prepared according to percent by volume, stirs and be prepared from, can packaging and storing, during use, powder of lacquer putty for use on and water are stirred into cream smectic by the volume ratio of 2:1.
Embodiment 2
Above-mentioned raw materials is prepared according to percent by volume, stirs and be prepared from, can packaging and storing, during use, powder of lacquer putty for use on and water are stirred into cream smectic by the volume ratio of 2:1.
Embodiment 3
Above-mentioned raw materials is prepared according to percent by volume, stirs and be prepared from, can packaging and storing, during use, powder of lacquer putty for use on and water are stirred into cream smectic by the volume ratio of 2:1.
Embodiment 4 acoustical testing
Use Eogo Audio (Shanghai) Co., Ltd. A36 type flat panel loudspeaker 2, one is coated with 3mm only with wall treasured board inner wall putty (matched group) on flat panel loudspeaker, another adopts the formula of embodiment 2, powder of lacquer putty for use on 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, until the putty on two flat panel loudspeakers is all fully dry make an uproar after, use specialty speaker test instrunment DASS test.
Apart from 1 meter of position of flat panel loudspeaker to be measured, recording result as follows: at the middle register of 1KHZ, experimental group 5db higher than the loudness of matched group, at treble, the loudness of experimental group is far above the loudness of matched group, and difference amplitude, up to 10db, namely promotes the audio of 3 times.Test result indicate that, audio is promoted effect quite substantially than matched group by experimental group, and during actual audition, than matched group, overall loudness occurs that volume significantly increases, and high pitch is relatively sharp bright.
