Description
One, technical field
The utility model relates to a kind of sound-absorbing porous material member of acoustic absorbant member, particularly a kind of flame-proof environmental protection.
Two, background technology
Along with the pay attention to day by day of China to environmental protection and health; the sound absorbing member that utilizes traditional sound-absorbing porous material to make in neighbourhood noise control and the control of hall tonequality can not adapt to the needs of present environmental protection and hygiene; as: the sound absorbing member that centrifugally glass-wool, super glass wool are made etc.; though such material can solve the sound absorption problem well; but in use can produce secondary pollution; human body is produced harm, can't satisfy environmental protection and hygienic requirements.Development along with the micropunch technology, be processed into the secondary pollution problem that the metal microperforated panel has fundamentally changed traditional material with sheet metal such as zinc coated sheet, stainless sheet steel, but because narrower frequency span, the average sound absorption coefficient of sound absorbing member that this microperforated panel is made is not very big, and aspect such as material price ratio does not have competitive power yet.The operational research of novel acoustic absorbant pollutes except solving material secondary, also will improve the acoustical behavior of acoustic absorbant simultaneously.For weak point such as overcome existing traditional sound-absorbing porous material environmental protection and health can not meet the demands and metal microperforated panel sound absorbing member sound sucting band is narrower, the applicant is through for many years exploration, particularly existing fiber-like material is studied disaggregatedly, from meta-aramid fibers or p-aramid fiber or fragrant sulfone synthetic fibre deep processing incision, solved environmental protection, the problem that the acoustical material that health and cost performance are high grows out of nothing, Chinese utility application was proposed on October 18th, 2009, i.e. " a kind of novel sound absorbing and insulating and heat insulating material and application thereof " (application number 200910036296.1), this provides advantage for solving environmental protection sound-absorbing porous material member better, but this patented claim is monomer material also, can't directly use.In a word, how to overcome the deficiencies in the prior art, become the great difficult problem that current acoustic absorbant member field needs to be resolved hurrily.
Three, summary of the invention
The purpose of this utility model is to provide a kind of acoustic absorbant member of flame-proof environmental protection for overcoming the deficiencies in the prior art, and this acoustic absorbant member not only satisfies the acoustical behavior requirement of sound-absorbing porous material, also satisfies fire-proof insulation and environment friendly and pollution-free requirement simultaneously.
Sound-absorbing porous material member according to a kind of flame-proof environmental protection that the utility model proposes, it comprises acoustic absorbant (1), facing material (2), skeleton (3), skeleton (3) is formed member hollow unit (4) with facing material (2), acoustic absorbant (1) is arranged in the member hollow unit (4), it is characterized in that sound absorption cotton or baffle blanket that acoustic absorbant (1) is made for meta-aramid fibers or para-aramid fiber or polysulphonamide fiber.Principle of the present utility model is to utilize the fiber finer of meta-aramid fibers or para-aramid fiber or polysulphonamide fiber, porosity height, characteristics that unit weight is little, acoustic energy very easily converts kinetic energy and heat energy etc. in fiber, make various sound absorbing members with it, its sound absorbing capabilities is better, longer service life, safer environmental protection.As making sound absorption cotton or baffle blanket with meta-aramid fibers or para-aramid fiber or polysulphonamide fiber, its unit weight is traditional centrifugally glass-wool part, but its low frequency (for example 200Hz) acoustical absorption coefficient reaches 2 times of centrifugally glass-wool, see for details Nanjing University's acoustics detection data contrasts.
The sound absorption cotton or the baffle blanket of meta-aramid fibers that the utility model is selected for use or para-aramid fiber or polysulphonamide fiber processing.The diameter of fiber is 10～14.56 μ m, and fibre length is 51mm, and the architectural feature of sound-absorbing porous material is at material surface and inside countless trickle spaces to be arranged all, and interconnects between these holes, and links to each other with ambient atmosphere, has certain gas penetration potential.Its solid portion spatially forms skeleton and is called grain, and grain is divided into many micro paths to bigger space.Fibre diameter is thin more, and the micro paths of composition is many more, and when sound wave incided material surface, the probability that acoustic energy converts heat energy to was many more, and acoustically effective is good more.The utility model compared with prior art its remarkable advantage is: first, sound absorption cotton or the good acoustical behavior of baffle blanket that the utility model utilizes meta-aramid fibers or para-aramid fiber or polysulphonamide fiber to make, the acoustical behavior of prepared sound-absorbing porous material member obviously is better than traditional sound-absorbing porous material member.The second, acoustic absorbant of the present utility model is in light weight, has reduced the requirement to stilt intensity.The 3rd, the utility model utilizes sound absorption cotton that meta-aramid fibers or para-aramid fiber or polysulphonamide fiber make or baffle blanket anti-flammability, avirulent premium properties, each class A of geometric unitA such as prepared sound absorption, sound absorption, noise elimination has fire-retardant, environmental protection, human body is not produced secondary pollution, characteristics such as degree of purification height.The 4th, the utility model utilizes the good mechanical property of meta-aramid fibers or para-aramid fiber or polysulphonamide fiber, prepared sound-absorbing porous material member, and its forming, indeformable, long service life can reach more than 20 years.The alternative traditional acoustic absorbant member of the utility model is widely used in sound absorption, household appliances (as washing machine, refrigerator, air-conditioning, refrigerating machine, loudspeaker etc.), the civil engineering and construction machinery of acoustic absorbant, dwelling house inside in transportation equipment such as vehicle (car, lorry, passenger train), steamer, aircraft and the hall performing art stadiums engineering, sqouynd absorption lowering noise of industrial premises etc.
