Abstract
The invention discloses a light antibacterial sound absorbing cotton, prepared from the following raw materials in parts by weight: 40-60 parts of dacron fiber, 10-15 parts of chitosan fiber, 10-15 parts of banana fiber, 10-15 parts of ES fiber, 0.3-0.5 part of didecyl dimethyl ammonium chloride, 2-4 parts of shell powder, 1-2 parts of silane coupling agent KH-550, 0.1-0.2 part of borneol, 2-4 parts of olive oil, and 10-15 parts composite resin. The sound absorbing cotton has better full frequency sound absorbing capability, obviously improved acoustic performance, has characteristics of light weight, ventilation softness, high comfort level and good antibacterial performance, and is good in use performance, wide in suitable range and high in practicability.
Description
Technical field
The present invention relates to acoustical technology field, particularly relate to antibacterial acoustical cotton of a kind of lightweight 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.And the general Unit Weight of common acoustical cotton is comparatively large, and soft, comfort level is poor.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides antibacterial acoustical cotton of a kind of lightweight and preparation method thereof.
The present invention is achieved by the following technical solutions:

Wherein compound resin is made up of the raw material of following weight portion: acrylamide 8-10, vinylacetate 4-6, potassium peroxydisulfate 0.05-0.1, Tween-80 0.1-0.2, lauryl sodium sulfate 0.5-1, aluminium chloride 1.5-2.5, sodium bicarbonate 4-6, water 40-50; Acrylamide, vinylacetate, lauryl sodium sulfate, Tween-80 and aluminium chloride are first added to the water to stir 5-10min by the preparation method of compound resin; then add potassium peroxydisulfate and under nitrogen protection 50-60 DEG C reaction 0.5-1h; finally add sodium bicarbonate and continue reaction 2-4h; after washing, grinding evenly, to obtain final product.
A preparation method for the antibacterial acoustical cotton of lightweight, comprises the following steps:
(1) by shredding after polyster fibre, chitin fiber, banana fiber 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 double-track suspended self-propelled conveyor, oyster shell whiting 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 80-90 DEG C of isothermal holding 8-12h, through surface treatment after cooling, obtain the antibacterial acoustical cotton of lightweight.
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, chitin fiber, banana fiber 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 light weight, the feature that ventilative, soft, comfort level is high, anti-microbial property is good, serviceability is good, applied widely, practical.
