Problems solved by technology

[0002] Currently commonly used non-woven noise-reducing materials often have the disadvantage that the fibers are easy to peel off and float away, especially in non-woven noise-reducing materials made of short fibers and ultra-short fibers
Its poor wear resistance not only shortens the service life of the material, but also reduces the noise reduction efficiency during use
In addition, chemical fiber non-woven noise-reducing materials have a high specific resistance, and the charges generated on the surface of the fabric are not easy to dissipate, and accumulate to generate high static voltage, which not only hinders the improvement of the grade of noise-reducing materials, but also limits non-woven fabrics. Expansion of application fields of woven noise reduction materials

Embodiment 1

[0029] Step (1): under the condition of continuous stirring, slowly add the graphite powder into the water-based polyurethane solution, the addition ratio is 1.0% of the water-based polyurethane solution (if the water-based polyurethane is 100ml, then add 1.0g of the graphite powder); at the same time, Add a certain amount of sodium dodecylsulfonate as a dispersing aid, and the addition ratio is 0.5% of the graphite powder mass (such as adding 1.0g of graphite powder, the amount of sodium dodecylsulfonate added is 5mg), stir After 0.5h, a mixed solution was obtained.

[0030] Step (2): Wash the nonwoven fabric substrate with distilled water to remove surface impurities; then, perform alkali reduction treatment: the concentration of the alkali solution is 2%, the alkali reduction treatment time is 60 minutes, and the temperature condition is 80°C.

[0031] Step (3): Place the nonwoven material after the alkali reduction treatment in the graphite powder water-based polyurethane ...

Abstract

The invention relates to an anti-static wear-resistant noise reduction and sound insulation material and a preparation method thereof. Non-woven cloth serves as a base body of the material, waterborne polyurethane and graphite powder serve as modifying agents, and a dispersing auxiliary is used for dispersing the graphite powder. The preparation method comprises the steps that the graphite powder is added into waterborne polyurethane under the stirring condition, the dispersing auxiliary is added, stirring is conducted, and a mixed solution is obtained; the non-woven cloth base body is washed, subjected to alkali-minimization treatment, placed in the mixed solution to be soaked, subjected to roll compacting treatment, dried and cured, and then the anti-static wear-resistant noise reduction and sound insulation material is obtained. The material has the high sound transmission loss decibel and the outstanding wear resistance and static resistance; in addition, the preparation method is easy to operate, low in production cost and suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of noise-reducing and sound-insulating materials and preparation thereof, in particular to an antistatic, wear-resistant, noise-reducing and sound-insulating material and a preparation method thereof. Background technique [0002] The currently commonly used non-woven noise-reducing materials often have the disadvantage that the fibers are easy to peel off and float away, especially in the non-woven noise-reducing materials made of short fibers and ultra-short fibers. Its poor wear resistance not only shortens the service life of the material, but also reduces the noise reduction efficiency during use. In addition, chemical fiber non-woven noise-reducing materials have a high specific resistance, and the charges generated on the surface of the fabric are not easy to dissipate, and accumulate to generate high static voltage, which not only hinders the improvement of the grade of noise-reducing materials, but also limit...
