Abstract
The invention discloses moxa floss composite sound-absorbing cotton. The moxa floss composite sound-absorbing cotton is prepared from, by weight, 40-60 parts of polyester fibers, 5-10 parts of moxa floss, 10-15 parts of ES fibers, 15-25 parts of kenaf fibers, 0.1-0.2 part of alkanolamide, 1-2 parts of silane coupling agent KH-550, 2-4 parts of medical stone powder, 0.1-0.2 part of butyl hydroxy anisd, 0.1-0.2 part of propylene glycol alginate, 2-4 parts of turpentine oil and 10-15 parts of composite resin. According to the sound-absorbing cotton, better full-frequency sound-absorbing capacity is achieved, the acoustic performance is obviously promoted, the effects of resisting bacteria and viruses, dispelling mosquitoes and other insects, adsorbing off-flavors and purifying air are achieved, the use performance is good, the application range is wide, and the practicability is strong.
Description
Technical field
The present invention relates to acoustical technology field, particularly relate to a kind of moxa 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.Meanwhile, along with growth in the living standard, people are also more and more higher to sound-absorbing material performance requirement, not only need good sound-absorbing effect, also have the demand of the aspects such as environmental protection, health care, comfort level.Wormwood has clearing and activating the channels and collaterals, dispels the health-care function of cold sensation of the genitalia, also has an unusually sweet smell, and fumigation energy mosquito repellent fly, clear miasma, has the function of antibacterial sterilization.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of moxa composite sound-absorbing cotton and preparation method thereof.
The present invention is achieved by the following technical solutions:

A preparation method for moxa composite sound-absorbing cotton, comprises the following steps:
(1) by shredding after polyster fibre, moxa, kenaf and ES fibers mixture, combing, lapping, then in 130-150 DEG C of solidification process 0.5-1h, after cooling, composite fibrofelt is obtained;
(2) composite fibrofelt evenly apply after being mixed with medical stone powder by compound resin is in (1) surperficial, then in 160-180 DEG C, hot-forming under 4-6MPa condition, obtain acoustical cotton matrix;
(3) first silane resin acceptor kh-550 is sprayed at acoustical cotton matrix surface in (2) and in 100-120 DEG C of isothermal holding 10-15min, then by all the other raw material mixing and stirring, again be sprayed on after acoustical cotton matrix surface in 40-60 DEG C of isothermal holding 3-5h, through surface treatment after cooling, obtain moxa composite sound-absorbing cotton.
Advantage of the present invention is:
The present invention has synthesized acrylamide/vinyl acetate-based composite porous resin, and be coated in the obtained composite fibrofelt surface of polyster fibre, moxa, kenaf and ES fibers mixture, composite sound-absorbing cotton material is obtained by hot-forming and surface modification treatment, obtained acoustical cotton structure is more reasonable, good in medium and low frequency section sound absorption properties, there is better full range sound absorbing power, acoustical behavior obviously promotes, also there is anti-bacteria and anti-virus, mosquito expelling, adsorb peculiar smell, effect of purifying air, serviceability is good, applied widely, practical.
