Description
Technical field
What the present invention relates to is a kind of mineral wool sound absorption board, and specifically, what the present invention relates to is a kind of mineral wool sound absorption board with mute function, and the preparation method of the mineral wool sound absorption board of described mute function.
Background technology
Mineral wool board is the new decorative material for building that integrates multiple functions such as light weight, sound-absorbing, fire prevention, heat insulation, decoration.Mineral wool board is harmless, pollution-free, be a kind ofly turn waste into wealth, the green building material of favorable environment.China began to produce from the seventies, and along with the develop rapidly of Building Trade in China, mineral wool board has been widely used in medium-to-high grade architectural decoration field.The consumption cumulative year after year, kind constantly updates.
Mineral wool board weight is lighter, is generally between the 350-450kg/m3, does not have sense of heaviness in the use, gives people's safety, relieved sensation, can alleviate the building deadweight, is a kind of safe decoration materials.Simultaneously mineral wool board also has good heat-insulating and fire-proof performance, and the average coefficient of thermal conductivity of mineral wool board is little, and easily insulation, and the primary raw material of mineral wool board is a mineral wool, and fusing point is up to 1300 ℃, and has higher fireproof performance.
At present mineral wool board has become a kind of general environmental friendly indoor ornament materials, its primary raw material mineral wool be slag through high temperature melting by supercentrifuge throw away wadding fibrous.Mineral wool in the mineral wool board is made up of numerous micropore, and when sound wave bump mineral wool board material surface, part is reflected back, and part is absorbed by sheet material, and some passes sheet material and enters the back cavity, thereby reduces reflected sound, has certain sound absorbing capabilities.
Along with the raising of people's living standard, the ornament materials performance demands is also improved constantly, improve the combination property of existing material, enlarge its purposes and become the task of top priority.
Prior art discloses multiple mineral wool board, for example, CN88213564 discloses a kind of floating clouds formula acoustical board, the described acoustical board of the document comprises string orifice plate and sound absorption material, the aperture that the aperture is respectively 5-6 and 1.5-3 millimeter is set at string on the orifice plate, aperture is evenly and is staggered, and described sound absorption material is super glass wool or mineral wool, but acoustical absorptivity only is 7.5 decibels under its 50% erection space.
CN89220712 discloses the cotton sound absorption decorative plate of a kind of mineral matter, described architectural surface of the document and substrate, and substrate is formed by the particulate minerals of spray glue is cotton, and still, its acoustically effective is still not ideal enough.
CN96228672 discloses the cotton acoustical board of a kind of rock (ore deposit), and the described acoustical board acoustically effective of the document is lower and need adopt the rigidity reinforcing rib in addition.
As seen, the sound absorbing capabilities of the mineral wool board of prior art awaits to improve.
Goal of the invention
Main purpose of the present invention is to provide a kind of mineral wool sound absorption board, and described mineral wool sound absorption board has the higher sound absorption coefficient and the sound sucting band of broad, can absorb the sound of various frequencies, plays quiet effect.
Another object of the present invention provides a kind of above-mentioned preparation method with mineral wool sound absorption board of mute function.
Purpose of the present invention can be achieved in the following manner, at first prepare the required slurry of mineral wool board and carry out making sheet, then wet plate is carried out drying and modify, get final product in the covering with paint of carrying out secondary coating and fine finishining, can be in preparation process, the hole that will absorb sound is molded directly within on the mineral wool board; Also can after drying, adopt the punch press perforation.The sound absorption hole that sound absorption bore dia of the present invention is 1-20mm, sound absorption hole can be the irregular or regular distribution in a kind of sound absorption hole of aperture on mineral wool board, also can be that the irregular or regular distribution in the sound absorption hole in more than one apertures is on mineral wool board.The sound absorption hole can be through hole, also can be blind hole.Mineral wool board of the present invention can be any mineral wool board of wet production in the prior art, can contain 80.46% granulated wool, 7.65% starch, 11.89% clay and other auxiliary material.
Because intensity reduces behind the pore-forming, can not satisfy actual needs, general atresia on therefore traditional mineral wool board.In order to guarantee to bore a hole the intensity of mineral wool board afterwards, the thickness of mineral wool board of the present invention is at least 14mm.The present invention adopts the hole forming method of gypsum plank, and the hole that will absorb sound in the vegetation process of mineral wool board is molded directly within on the mineral wool board.
The regular distribution mode in sound absorption of the present invention hole can be described sound absorption hole with the linear pattern that center line the is parallel to each other cross linear that the hole intersects at the mineral wool board center of arranging, absorb sound is to be even or radial on the center line to arrange.When the straight line that is parallel to each other with center line when described sound absorption hole is arranged, form parallelogram or trapezoidal such as square, rectangle between the sound absorption hole of same apertures, the cross linear that intersects at the mineral wool board center when the sound absorption hole is when being even or radial arranging on the center line, can form circular sound absorption hole, this is that can to regard the mineral wool board center as be the center of circle, is distributed with the sound absorption hole on each radius with the circle five equilibrium.The sound absorption hole can also and be fit to other shapes of the present invention for ellipse, 8 fonts and arrange; Describedly distribute radially, be meant when the sound absorption pore size distribution on the radius that will justify five equilibrium from the center of circle time, the sound absorption pore size distribution is at the bearing of trend along radius, along the bearing of trend of radius absorb sound hole center to center distance identical, increase gradually or reduce.
Preferably, sound absorption of the present invention hole is distributed on the mineral wool board brokenly for more than one sound absorption hole.Perforated percentage is at least 3%.
Preferred, sound absorption of the present invention hole is evenly or radially to arrange and be distributed on the mineral wool board in sound absorption hole, a kind of aperture, or the sound absorption hole in two kinds of different apertures evenly or radially is distributed on the mineral wool board.
Most preferably, sound absorption of the present invention hole be the sound absorption hole of 6mm or 6mm and two kinds of aperture combination of 10mm with square arrangement on mineral wool board, pitch of holes is 28mm.
The sheet layer that mineral wool sound absorption board ore deposit with mute function of the present invention isolates at further stickup one of non-decorative cover one side and Dicoration base material, described sheet material can be sheet materials such as paper, cloth, plastics.As mulberry paper, wall paper etc.
The present invention is by having the sound absorption hole of mute function in traditional mineral wool board increase, improved the absorption function of mineral wool board greatly to various frequency sound, have the higher sound absorption coefficient and the sound sucting band of broad, can absorb the sound of various frequencies, play quiet effect.
