Abstract
The invention discloses flame-retardant sound-absorbing cotton. The cotton comprises a top surface layer, a back surface layer, and a fiber cotton layer which is clamped between the top surface layer and the back surface layer; the top surface layer and the back surface layer are made of non-woven fabric. The cotton is characterized in that the non-woven fabric is prepared from raw materials in the following weight parts through a melt blown method: 100 parts of isotatic polypropylene, 2 parts to 3 parts of silane coupling agent KH-550, 3 parts to 4 parts of diantimony trioxide, 2 parts to 3 parts of carboxymethyl cellulose, 1 part to 2 parts of talcum powder, 12 parts to 15 parts of tributyl citrate, 2 parts to 3 parts of aluminium hydroxide, 1 part to 2 parts of praseodymium chloride, 1 part to 2 parts of lanthanum nitrate, 3 parts to 4 parts of carclazyte, 10 parts to 12 parts of bamboo charcoal, 10 parts to 12 parts of tuckahoe, 2 parts to 3 parts of platycodon grandiflorum, 2 parts to 3 parts of cordate houttuynia, and 4 parts to 5 parts of additive. The sound-absorbing cotton which is prepared through the preparation method has the advantages of good flame-retardant performance, flat appearance, strong absorbability effect, significant sound-absorbing effect and the like.
Description
Technical field
The present invention relates to Nonwovens In Technology, be specifically related to a kind of fire-retardant 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 fabric 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 fire-retardant acoustical cotton and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
