The invention discloses kapok fiber composite sound absorbing cotton. The kapok fiber composite sound absorbing cotton is prepared from, by weight, 40-60 parts of polyester fibers, 20-30 parts of kapok fibers, 5-10 parts of polypropylene fibers, 10-15 parts of ES fibers, 0.5-1 parts of coco fatty diethanol amide, 0.5-1 part of sodium stearate, 2-4 parts of cottonseed oil, 1-2 parts of silane coupling agent KH-550, 2-4 parts of zeolite powder, 1-2 parts of talcum powder and 10-15 parts of composite resin. The kapok fiber composite sound absorbing cotton has better full-frequency sound absorbing capability, the acoustical performance is remarkably improved, and the kapok fiber composite sound absorbing cotton further has the anti-bacterial, anti-moth and mildew-proof functions, is good in use performance, wide in application range and high in practicability.
Description
Technical field
The present invention relates to acoustical technology technical field, particularly relate to a kind of bombax cotton composite sound-absorbing cotton and preparation method thereof.
Background technology
At society, noise pollution become after water pollutions, atmosphere pollution by world wide one of the Environmental Pollution problem paid close attention to.Using sound-absorbing acoustic material to carry out sound insulation noise reduction is the conventional means of administering noise pollution.Acoustical cotton conventional in the market has glass fibre acoustical cotton, sponge, polyester fiber acoustical cotton etc.Glass fibre cotton easily causes pruitus and respiratory tract anaphylaxis, has harm to human body, is not suitable for indoor use.Sponge major part is closed cell foamed material, and sound absorption qualities is limited, is more suitable for for field of thermal insulation.And the frequency range of conventional polyester fiber acoustical cotton sound-absorbing is narrower, only centering high-frequency sound has good absorption, limited to the assimilation effect of low-frequency sound.Bombax cotton be in natural ecological fiber the most carefully, the Fiber Materials that the lightest, degree of hollowness is the highest, its fineness only has 1/2 of cotton fiber, and hollow rate but reaches more than 86%, and the 2-3 being general cotton fiber doubly, is suitable for sound-absorbing material, promotes sound absorption qualities.Bombax cotton also have bright and clean, antibacterial, mothproof, mildew-resistant, softly, not easy entanglement, ecology, the feature such as warming.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of bombax cotton composite sound-absorbing cotton and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of bombax cotton composite sound-absorbing is cotton, and it is obtained by the raw material of following weight parts:
