Abstract
The invention provides the efficient acoustic fragrance powder of lacquer putty for use on of a kind of concealed flat panel loudspeaker, it contains the component of following percent by volume: 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%, essence 0.5 5%.The efficient acoustic fragrance 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 fragrance powder of lacquer putty for use on of a kind of concealed flat panel loudspeaker.
Background technology
Concealed flat panel loudspeaker in evolution in recent years, each as a part of current market of putty material of its sounding body
Planting formula and all do not reach matched requirement, the powder of lacquer putty for use on density of existing inner wall decoration is big, volume weight, and serious stop is the most in a large number
Absorb acoustic wave energy, make sound intensity reduce up to more than 10dB, and owing to original formula is based on ground calcium carbonate, due to
Deadweight and the reason of wave absorption, while reducing sound loudness, the high frequency sent by sound equipment has been also carried out part and has absorbed, from
And cause the disappearance that part frequency band occurs during audition.For making up sound intensity needs, to additionally strengthen a large amount of volume, cause whole
Individual sound system efficiency poor efficiency, adds caloric value and the unstable factor of system.
Summary of the invention
It is an object of the invention to provide the efficient acoustic fragrance powder of lacquer putty for use on of a kind of concealed flat panel loudspeaker, it contains such as lower volume hundred
The component of proportion by subtraction:
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%, essence
0.5-5%.
Preferred each component ratio 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%, essence
0.5-5%.
Wherein said essence is lavandula angustifolia powder.
The efficient acoustic powder of lacquer putty for use on of a kind of concealed flat panel loudspeaker of the present invention, it can also be containing the component of following percent by volume
In one or more:
Precipitated calcium carbonate 5-30%, white cement 2-10%, ultrawhite ash calcium 1-5%, titanium dioxide 1-5%；
The preferably ratio of 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 pressed the volume ratio of 2:1
Stir into cream smectic.
The efficient acoustic fragrance powder of lacquer putty for use on density of the concealed flat panel loudspeaker of the present invention is little, lightweight, and sound wave stops little, absorption
Few, the decay to sound intensity can be reduced, the absorption of frequency range each to audio frequency is less simultaneously, and 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, improves the efficiency of whole system and increases the graceful journey of sound
Degree.The powder of lacquer putty for use on of the present invention, while solving the acoustic characteristic of powder of lacquer putty for use on used by concealed flat panel loudspeaker, allows and progressively releases in room
Release light delicate fragrance, spectators can be made to be greatly increased the fragrance of appreciation, also embody the lofty taste of owner, essence simultaneously
Abnormal smells from the patient can fit up at the beginning of be added with the hobby of house-owner, owing to this formula quality after enforcement is soft, can be more lasting
Holding fragrance.
The 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, constant
Color, non-yellowing, moisture absorption is few, without any composition containing formaldehyde in water-tolerant, formula, high-environmental, permanent fragrant, order
Spectators are in a cheerful frame of mind.
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 of meeting quality.
4, application property is good, it is easy to operation.
5, the suitability is strong, in addition to concealed flat panel loudspeaker uses, 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 remaining component is the most commercially available.
Embodiment 1
Each component is weighed respectively according to following percent by volume:
By above-mentioned raw materials according to percent by volume prepare, stir and be prepared from, can packaging and storing, during use, by powder of lacquer putty for use on
Cream smectic is stirred into by the volume ratio of 2:1 with water.
Embodiment 2
By above-mentioned raw materials percent by volume prepare, stir and be prepared from, can packaging and storing, during use, by powder of lacquer putty for use on and water
Cream smectic is stirred into by the volume ratio of 2:1.
Embodiment 3
By above-mentioned raw materials percent by volume prepare, stir and be prepared from, can packaging and storing, during use, by powder of lacquer putty for use on and water
Cream smectic is stirred into by the volume ratio of 2:1.
Embodiment 4 acoustical testing
Using Eogo Audio (Shanghai) Co., Ltd. A36 type flat panel loudspeaker 2, one only with wall treasured board inner wall putty (matched group)
Being coated with 3mm on flat panel loudspeaker, another uses the formula of embodiment 2, and by the volume ratio of 2:1, powder of lacquer putty for use on and water are stirred into cream
Smectic, modulate after (as experimental group) on flat panel loudspeaker, be coated with 3mm, until the putty on two flat panel loudspeakers is the most dry make an uproar after,
The speaker test instrunment DASS using specialty tests.
Apart from 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 loudness of matched group
High 5db, at treble, the loudness of experimental group is far above the loudness of matched group, and difference amplitude is up to 10db, i.e. promotes the sound of 3 times
Effect.Test result indicate that, experimental group promotes effect quite substantially than matched group to audio, and during actual audition, overall loudness is than comparison
Group occurs that volume significantly increases, and high pitch is relatively sharp bright.
