Abstract
Disclosed antibacterial sound-absorbing cotton consists of a top layer, a bottom layer, and a fiber cotton layer disposed between the top layer and the bottom layer. The top layer and the bottom layer are made from a non-woven fabric material, and the antibacterial sound-absorbing cotton is characterized in that the non-woven fabric material is prepared from the following raw materials in parts by weight by employing a melt blowing method: 100 parts of isotactic polypropylene, 12-15 parts of methyl methacrylate, 1-2 parts of 2-methylsuccinic acid, 1-2 parts of chlorothalonil, 2-3 parts of calcium stearate, 12-15 parts of diisobutyl phthalate, 4-6 parts of paraffin oil, 1-2 parts of zinc oxide, 10-12 parts of eggplant straw, 4-5 parts of active carbon, 2-3 parts of spatholobus stem, 1-2 parts of Chinese prickly ash, 1-2 parts of achyranthes aspera L., 2-3 parts of common clubmoss herb and 4-5 parts of an auxiliary agent. The prepared sound-absorbing cotton has antibacterial property, and is capable of satisfying the usage requirement of special industries, and the product provided by the invention has the advantages of large porosity, strong adsorptivity and the like.
Description
Technical field
The present invention relates to Nonwovens In Technology, be specifically related to a kind of antibacterial acoustical cotton 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 antibacterial acoustical cotton 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 antibacterial acoustical cotton, by top coat, back layer, and the cellucotton layer being clipped between top coat and back layer forms, described top coat, back layer adopts nonwoven cloth material, nonwoven described in it is characterized in that is made by meltblown by the raw material of following weight portion: isotactic polypropylene 100, methyl methacrylate 12-15, dimethyl succinic acid 1-2, tetrachloro isophthalic diformazan eyeball 1-2, calcium stearate 2-3, diisobutyl phthalate 12-15, paraffin oil 4-6, zinc oxide 1-2, eggplant stalk 10-12, active carbon 4-5, reticulate millettia 2-3, Chinese prickly ash 1-2, achyranthes aspera 1-2, lycopodium calvatum 2-3, auxiliary agent 4-5.
Described auxiliary agent is made by following raw materials in part by weight: clay 10-12, nano-sized carbon 1-2, polytetrafluoroethylene powder 3-4, antioxidant NBC 1-2, isopropyl distearyl acyl-oxygen base Aluminate 2-3, zinc dialkyl dithiophosphate 2-3, magnetite 2-3, epoxidized soybean oil 35-40, n-propyl gallate 3-4, coix seed oil 2-3, vanadium diboride 1-2, Tea Polyphenols 2-3; Preparation method sends into clay, magnetite in calcining furnace and calcine 2-3 hour at 720-740 ℃, then, takes out, and sends in the hydrochloric acid solution of 10-15% and soaks 2-3 hour, filters, and obtains filter residue, with clear water, cleans, and dries, grinds to form 400-600 order powder; Gained powder mixes with other residual components, is heated to 60-70 ℃, and stirring reaction 40-50 minute is cooling, grinds to form slurry, obtains.
The preparation method of described a kind of antibacterial acoustical cotton, is characterized in that comprising the following steps:
(1), reticulate millettia, Chinese prickly ash, achyranthes aspera, lycopodium calvatum are merged and pulverize 280-350 order powder, then, to the powder air blast of gained, it is seethed, to spray form paraffin oil in the powder seething, the two is fully mixed;
(2), eggplant stalk is sent in retort, at 5245-660 ℃, 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 is green cheap and easy to get, add medicinal herb components to make the acoustical cotton making there is antibiotic property, can meet the instructions for use of special industry, product of the present invention also has the advantages such as porosity is large, adsorptivity is strong.
