Abstract
The invention discloses an antistatic sound-absorbing cotton. The antistatic sound-absorbing cotton comprises a top layer, a back layer and a cellucotton layer sandwiched between the top layer and the back layer, wherein the top layer and the back layer are made of a non-woven fabric material. The antistatic sound-absorbing cotton is characterized in that the non-woven fabric is prepared from the following raw materials by weight through melt-blowing: 100 parts of isotatic polypropylene, 7 to 9 parts of fatty alcohol-polyoxyethylene ether, 2 to 3 parts of alkyl ethyl ether polysiloxane polysilicone, 2 to 3 parts of aluminum phosphate, 1 to 2 parts of tin oxide, 13 to 16 parts of glycerol triacetate, 1 to 2 parts of magnesium silicate, 1 to 2 parts of nanometer silica, 2 to 3 parts of calcium alginate, 1 to 2 parts of sodium silicate, 20 to 24 parts of twigs, 1 to 2 parts of mint leaves, 2 to 3 parts of licorice, 3 to 4 parts of gynostemma pentaphylla and 4 to 5 parts of an auxiliary agent. According to the invention, a melt-blowing process is used for preparation of the non-woven fabric and has the advantages of easiness, good controllability and high production efficiency; and the prepared sound-absorbing cotton provided by the invention has the advantages of an antistatic property, soft hand feel, smoothness, good surface flatness, strong adsorptivity, a good sound-absorbing effect, etc.
Description
Technical field
The present invention relates to Nonwovens In Technology, be specifically related to a kind of antistatic sound-absorbing 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 antistatic sound-absorbing cotton and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
