Abstract
The invention discloses acoustic wool with excellent weather resistance. The acoustic wool comprises a top layer, a back layer and a cellucotton layer clamped between the top layer and the back layer, wherein both the top layer and the back layer are made of non-woven fabric materials. The acoustic wool is characterized in that the non-woven fabrics are prepared with a melt-blowing method and prepared from raw materials in parts by weight as follows: 100 parts of isotactic polypropylene, 5-7 parts of EPDM (ethylene-propylene-diene monomer), 2-3 parts of polyvinyl alcohol, 1-2 parts of a coupling agent KH550, 13-16 parts of triethyl citrate, 1-2 parts of red phosphorus, 1-2 parts of sodium bicarbonate, 12-14 parts of chestnut shells, 2-3 parts of zinc chloride, 1-2 parts of Arabic gum, 2-3 parts of rhizoma cyperi, 1-2 parts of divaricate saposhnikovia roots, 2-3 parts of angelica sinensis and 4-5 parts of an assistant. The prepared acoustic wool has the advantages of good weather resistance, excellent chemical resistance, good appearance flatness, high absorbability, remarkable sound absorption effect and the like.
Description
Technical field
The present invention relates to Nonwovens In Technology, be specifically related to a kind of acoustical cotton with excellent weather resistance and preparation method thereof.
Background technology
Noise directly affects the raising of people's physical and mental health and quality of life, for a long time in noise circumstance, can cause that hearing loss even may bring out some diseases.Will be away from noise, what we can do is exactly sound-absorbing and sound insulation.Acoustical cotton, the high-frequency noises vibrational energy that produces in life can be converted to acoustical cotton inside fine count fiber kinetic energy and lead into heat energy and disappear, reach the function of absorbing sound and lowering noise.
Acoustical cotton can be superimposed with multi-layer nonwoven fabrics, or other material of arranging in pairs or groups, and makes sound-absorbing, acoustic material.Nonwoven is that textile staple or long filament are carried out to orientation or random support row, forms fibre net structure, presents many tiny gaps, this gap can be regarded hole as, has adsorption function, therefore, acoustical cotton can be considered porous material, has good sound-absorbing, heat-insulation warm keeping performance.Acoustical cotton is widely used in the industries such as building, electrical equipment, automobile, machinery as a kind of gasket material, mainly play the effect of sound insulation.But all there is more deficiency in existing acoustical cotton product and manufacture method thereof, main manifestations is: not environmental protection of manufacture craft; Sound-absorbing effect is general; Chemical resistance is low, cannot meet Code in Hazardous Special Locations instructions for use; Temperature resistant grade is low; Do not carry out flame treatment; Product caking ability is inadequate, fugitive, tension intensity is poor; Outward appearance and flatness are inadequate, thickness relatively large deviation etc.
Summary of the invention
Object of the present invention is just to provide a kind of acoustical cotton with excellent weather resistance and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of acoustical cotton with excellent weather resistance, by top coat, back layer, and the cellucotton layer being clipped between top coat and back layer forms, described top coat, back layer adopt nonwoven cloth material, and the nonwoven described in it is characterized in that is made by meltblown by the raw material of following weight portion: isotactic polypropylene 100, EPDM5-7, polyvinyl alcohol 2-3, coupling agent KH550 1-2, triethyl citrate 13-16, red phosphorus 1-2, sodium acid carbonate 1-2, chestnut shell 12-14, zinc chloride 2-3, Arabic gum 1-2, rhizoma cyperi 2-3, windproof 1-2, Radix Angelicae Sinensis 2-3, auxiliary agent 4-5.

Described a kind of preparation method with the acoustical cotton of excellent weather resistance, is characterized in that comprising the following steps:
(1), rhizoma cyperi, windproof, Radix Angelicae Sinensis are merged and pulverize 200-270 order powder, then, to the powder air blast of gained, it is seethed, to spray form Arabic gum in the powder seething, the two is fully mixed;
(2), chestnut shell is sent in retort, at 550-670 ℃, 3-4 hour is processed in charing, takes out, and is ground into powder;
(3), isotactic polypropylene is heated to molten condition, add step (1), (2) material, stir;
(4), in step (3) material, add other residual components, fully stir, mix, by nozzle, spray and thread make nonwoven.
The present invention has following beneficial effect: the present invention adopts meltblown to prepare nonwoven, have that technique is simple, raw material green cheap and easy to get, controllability good, production efficiency is high, the acoustical cotton making has the advantages such as good weatherability, chemical resistance is good, flat appearance degree is good, the strong sound-absorbing effect of adsorptivity is obvious.
