Abstract
The utility model relates to a compound lining cloth of sound is inhaled to ultralight for (window) curtain, the lining cloth comprises three layer construction, and upper and lower two-layer is multi-functional composite fiber spunbonded nonwoven, and the intermediate level is the balsa wood, forms through the high temperature gluing agent is compound. The utility model discloses changed traditional function singleness, only had the casement of shading function, increased the acoustic performance of sound absorption noise removal, had advantages such as the quality ultralight, environmental protection pollution-free in addition.
Description
Technical Field
The utility model relates to an inhale sound material technical field, specifically be an ultralight inhales compound lining cloth of sound for (window) curtain.
Background
The balsa wood is a wood with ultra-light material and high practical value, has good mechanical property, enough strength and hardness and better insulativity, has the air-dry specific gravity of only about 0.12 per cubic meter of wood, is uniform in material, is easy to process, and is widely applied to aircraft structures, insulating materials, sound insulation equipment and the like.
With the improvement of living standard and housing condition of people, the noise pollution problem of housing becomes a new problem affecting the life and health of residents. The curtain mainly comprises outdoor noise transmitted by doors and windows, indoor heating, sound transmitted by upper and lower drainage pipelines and the like, so that the sound insulation treatment is preferably carried out on the doors and windows, the ground and the walls with poor sound insulation effect in order to have a comfortable environment, and the external noise can be reduced by 20-40% by selecting a curtain with the sound absorption and noise elimination function.
Although the existing sound absorption and noise removal technology is well applied to different fields, a considerable part of sound absorption materials have the factors of poor environmental adaptability, large volume, single function, high construction cost and the like, and are not popularized in a large range all the time. Therefore, a multifunctional and efficient sound-absorbing material harmless to human bodies becomes a hot spot of current research.
SUMMERY OF THE UTILITY MODEL
The utility model aims at prior art's weak point, provide a compound lining cloth of sound is inhaled to ultralight for (window) curtain, changed traditional function singleness, only have the casement of shading function, increased the acoustic performance of sound absorption noise elimination, have advantages such as the quality ultralight, environmental protection are pollution-free in addition.
The technical solution of the utility model is that: the utility model provides an ultralight inhales compound lining cloth of sound for (window) curtain, the lining cloth comprises three layer construction, and the upper strata is multi-functional composite fiber spunbonded nonwoven, and the intermediate level is balsa wood, and the lower floor is multi-functional composite fiber spunbonded nonwoven, forms through the high temperature gluing agent is compound.
Preferably, the multifunctional composite fiber spunbonded nonwoven fabric is formed by spunbonded needle Punching of Polypropylene (PP), polytetrafluoroethylene fibers and carbon fibers.
Preferably, the thickness of the upper and lower layers of multifunctional composite fiber spun-bonded non-woven fabric is 1-3 mm.
Preferably, the thickness of the balsa wood is 1-3 mm.
Has the advantages that: the utility model discloses non-woven fabrics is spun by polypropylene (PP), polytetrafluoroethylene fibre and carbon fiber and is glued the acupuncture and form, has high temperature resistant, inhales the sound function, and basha wood physical properties is good, and the quality is ultralight, both thermal-insulated, gives sound insulation again, has changed traditional function singleness, has only the casement of shading function, has increased the acoustic performance of sound absorption noise removal, has advantages such as ultralight, the environmental protection pollution-free of quality in addition.
