Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Please refer to figure 1 , the present invention provides a schematic structural diagram of shockproof and sound-absorbing cotton, which includes an upper non-woven fabric layer 1, a two-component cotton layer 2 and a lower non-woven fabric layer 3 arranged in sequence from top to bottom, and polyolefin Adhesive bonding; the composition of the two-component cotton is polypropylene fiber and vacuum polyester staple fiber, and the mass ratio of polypropylene fiber to vacuum polyester staple fiber is 6:4.

[0024] Preferably, the diameter of the polypropylene fibers is 5-15 μm.

Abstract

The invention provides quakeproof silencing cotton and a preparation method thereof. The quakeproof silencing cotton comprises an upper non-woven fabric layer, a double-component cotton layer and a lower non-woven fabric layer which are sequentially arranged from top to bottom and are adhered to one another by polyene glue, wherein the double-component cotton layer is prepared from polypropylene fibers and vacuum polyester staple fibers, and the mass ratio of the polypropylene fibers to the vacuum polyester staple fibers is 6 to 4. The produced double-component cotton is thin and has non-toxic and environmental-friendly effects; furthermore, the silencing, heat-insulation and quakeproof effects of the cotton are enhanced; meanwhile, the upper and lower surfaces of the cooled double-component cotton is adhered to the non-woven fabric layers by the polyene glue, and the adhered product is subjected to hot roller pressing molding, so that the silencing cotton is high in rigidity, low in thickness and high in durability.

Description

technical field [0001] The invention relates to the field of sound-absorbing cotton production, in particular to an anti-shock sound-absorbing cotton and a preparation method thereof. Background technique [0002] Existing car interiors all need to use sound-absorbing cotton to achieve sound-absorbing and shock-proof effects. At present, the sound-absorbing and shock-proof effects of existing sound-absorbing cotton are not good. At the same time, the thickness is too thick, the weight is relatively heavy, and the hardness is not enough. Shorter, when the service life is up, it is easy to cause pollution to the environment inside the car, so it cannot meet the use standard. Contents of the invention [0003] Aiming at the problems existing in the above prior art, the present invention provides a kind of anti-shock and sound-absorbing cotton and its preparation method, which solves the problem of poor sound-absorbing and anti-vibration effects of traditional sound-absorbing ...
