Abstract
The utility model relates to a full acoustic baffle frequently, adopt the fibreboard including the bottom plate, one deck hot melt nethike embrane is covered on the fibreboard surface, then will perforate wooden skin and cover on the hot melt nethike embrane, can obtain full acoustic baffle frequently after handling through individual layer wainscot hot press at last. The utility model discloses the fibreboard that uses is behind the compound wooden skin of perforating, and its sound absorption effect has obtained the improvement, the surface has had the texture of wooden skin, decorative reinforcing, self light in weight, healthy environmental protection, easily installation.
Description
Technical field
The utility model relates to building material field, is specifically related to a kind of full-frequency sound absorption plate.
Background technology
Along with improving constantly of living standard, people more and more pay attention to quality of life.A comfortable live and work environment becomes the most basic requirement of people.Now, noise exerts a certain influence to the living environment of the mankind as large pollution sources.In order to solve the harm that noise brings, increasing sound absorption and noise reduction material and device have come into the life of people.Although but some material solves the harm of noise in the middle of sound absorption material miscellaneous, but bring otherwise problem, as: the inadequate environmental protection of material apparatus, can discharge pernicious gas; Material apparatus is too heavy, installs inconvenience; Material apparatus outward appearance is dull, does not have desirable decorative effect.Therefore a kind of product of people's active demand, can solve the problem the puzzlement brought.
Summary of the invention
The utility model base plate adopts fiberboard, and fibreboard surface covers one deck hot melt net, then overlays on hot melt net by wooden for perforation skin, namely obtains full-frequency sound absorption plate finally by after the process of individual layer speed veneering hot press.
The concrete technical scheme of the utility model is as follows:
Base plate adopts fiberboard, and fibreboard surface covers one deck hot melt net, then covers on hot melt net by wooden for perforation skin, namely obtains full-frequency sound absorption plate finally by after the process of individual layer speed veneering hot press;
Described base plate material can be polyester fiber board, the one in wood fibre board or fiberglass fiber plate, and thickness is 5 ~ 20mm;
Described hot melt net is that Shanghai Tian Nian material Science and Technology Ltd. produces, grammes per square metre 15 ~ 60g/m
2;
Described perforation wood 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, perforated percentage 0.5 ~ 1.5%;
The running parameter of individual layer speed veneering hot press 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:
Material of the present utility model is all environment-friendly materials from base plate, adhesive to plane materiel, and the finished product acoustical absorptivity after compound improves further, and has light weight, heat-insulation and heat-preservation, the ornamental feature such as strong, easy for installation.Therefore, this low-frequency acoustical board can meet the requirement of Vehicles Collected from Market to ornament materials to a great extent.
Accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model.Wherein 1 is the wooden skin of perforation, and 2 is hot melt net, and 3 is fiberboard.
Detailed description of the invention
Embodiment 1:
The utility model with the thick polyester fiber board of 9mm for base plate; Then hot melt net is overlayed on polyester fiber board surface, hot melt net grammes per square metre is 50g/m
2; Then wooden for perforation skin is overlayed on hot melt net surface, wooden skin of boring a hole is beech material, and its thickness is 0.5mm, and perforated percentage is 0.8%; Finally sheet material is put into individual layer speed veneering hot press to process, can obtain full-frequency sound absorption board finished product, the heating-up temperature of individual layer speed veneering hot press is 180 DEG C, and pressure is 0.2Mpa, and pressing time is 0.5h.
Obtained full-frequency sound absorption plate 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.
