Abstract
The utility model relates to a low frequency acoustic baffle, including using the fibreboard as the base plate to the hot melt nethike embrane as the gluing agent with wooden skin complex on the fibreboard, obtain low frequency acoustic baffle promptly. The utility model discloses the fibreboard that uses has the apparent sound absorption that lands, can effectively reduce the environmental noise. Behind the compound wooden skin, this acoustic baffle has better effect to the absorption of low -frequency noise. The fibreboard has porous structure in addition, can also play better heat preservation effect.
Description
Technical field
The utility model relates to building material field, is specifically related to a kind of low-frequency acoustical board.
Background technology
Along with the development of society, the requirement of people to quality of life is more and more higher.A comfortable living and working environment becomes the most basic selection of people.Now, noise pollution is almost ubiquitous, and controling environment to pollute has become people's difficult problem in the urgent need to address.
Current sound absorption material mainly can be divided into two large classes: inorganic fibers and organic polymer fiber material.The advantages such as it is good that inorganic fibers has sound absorbing capabilities, and light weight does not fire, corrosion-resistant, ageing-resistant are therefore wider in field of acoustics application.But it also has the shortcoming that cannot overcome: inorganic fibers is more crisp, frangibility is formed to be polluted, and stimulates human body skin, easily causes possible permanent damage after suction.Organic fibrous material is better to the absorptive capacity of high-frequency noises, and range of application is also comparatively extensive.But the assimilation effect of organic fibrous material to low-frequency noise is not ideal enough, and the organic fibrous material of considerable part can discharge pernicious gas when running into high temperature, is detrimental to health.Therefore, health environment-friendly, lightweight decorating material become the first-selection of people.
Summary of the invention
The utility model take fiberboard as substrate, by the acoustical board with wooden skin produced with combination, has good acoustically effective, especially to low-frequency noise.
The concrete technical scheme of the utility model is as follows:
Take fiberboard as substrate, be compounded on fiberboard using hot melt net as adhesive and wooden skin, namely obtain low-frequency acoustical board;
Described fiberboard material can be polyester fiber board, the one in fiberglass fiber plate or wood fibre board, and thickness is 5 ~ 20mm;
Described hot melt net is produced by Shanghai Tian Nian material Science and Technology Ltd., grammes per square metre 15 ~ 60g/m
2;
Described wooden skin is natural veneer, and material is the one in beech, ebony, white poplar, Manchurian ash, black walnut or husky Billy, and wooden skin thickness is 0.3 ~ 1mm;
The running parameter of heat-pressing compound machine is: heating-up temperature 150 ~ 200 DEG C, pressure 0.1 ~ 0.2Mpa, pressing time 0.5 ~ 1.5h.
The advantage that the utility model has is:
The utility model substrate selected materials has the feature of environmental protection, nontoxic, nonirritant, free from extraneous odour, sound absorption reduction, thermal insulation.The wooden skin material of compound is natural veneer, and health environment-friendly, has better effects to the absorption of low-frequency noise, and the wood grain of outward appearance is succinctly attractive in appearance, ornamental extremely strong.The adhesive used is environment-friendly type hot melt nethike embrane.This low-frequency acoustical board has the advantage of each ingredient above-mentioned, and it strengthens further to the assimilation effect of low-frequency noise.This low-frequency acoustical board also has environmental protection, light weight, heat-insulation and heat-preservation, the feature such as easy for installation in addition.
Accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model.Wherein 1 is wooden skin, and 2 is hot melt net, and 3 is fiberboard.
Detailed description of the invention
Embodiment 1:
The utility model substrate adopts polyester fiber board, and thickness is 9mm; Then hot melt net and wooden skin are placed in position on heat-pressing compound machine; Hot melt net grammes per square metre is 50g/m
2; Wood skin is beech material, and its thickness is 0.5mm; Finally can obtain low frequency absorption board finished product by heat-pressing compound machine process, the heating-up temperature of heat-pressing compound machine is 180 DEG C, and pressure is 0.2Mpa, and pressing time is 1h.
Obtained low-frequency acoustical board is carried out acoustically effective test.The detection of sound absorption coefficient is according to being GB/T20247-2006 " acoustic absorptivity measurements of acoustic reverberation room ", and testing result is in table 1.
