Problems solved by technology

The sound-absorbing materials made of the above-mentioned fibers often generate static electricity due to friction during use and processing, especially in a dry environment. The generation of static electricity may not only affect the normal production, but also induce fire accidents
At present, the common sound-absorbing cotton, sound-absorbing non-woven fabric and sound-absorbing paper in my country are only considered in terms of sound-absorbing function, flame-retardant performance and paper strength in terms of research and production, without considering the antistatic performance of the material. For example, the Chinese patent application No. CN200610116596 "Sound-absorbing non-woven fabric and its manufacturing method", the Chinese patent application No. CN201110184238.0 "A sound-absorbing paper material and its manufacturing method" and the Chinese patent No. ZL200810017903 " Preparation process of composite sound-absorbing paper”

Embodiment 1

[0015] First, the coniferous wood chemical pulp containing plant fibers and conductive fibers are made into substrates with an inclined wire paper machine, and the mass ratio of plant fibers to conductive fibers is 4:1. The volume specific resistance of the obtained substrate was 10 10 Ω.cm.

[0016] Then, an antistatic dipping solution is prepared. The preparation process of antistatic impregnating liquid is: dissolving dye and flame retardant in water to form an aqueous solution, then adding water repellent and modified starch to the aqueous solution to form a slurry, and then adding the antistatic agent to the slurry , by stirring, the antistatic agent is evenly dispersed in the slurry. In the antistatic dipping solution, the mass percentage concentration of the flame retardant is 6%, the mass percentage concentration of the water repellent agent is 6%, the mass percentage concentration of the dye is 1%, and the mass percentage concentration of the modified starch is 5%,...

Abstract

The invention discloses an antistatic sound absorption paper and a preparation method thereof. The antistatic sound absorption paper contains plant fibers, conductive fibers and an antistatic agent. The preparation method of the antistatic sound absorption paper comprises the following steps of: (1) making a base material by utilizing the plant fibers and the conductive fibers; (2) preparing an antistatic impregnation liquid by adding the antistatic agent in water; (3) impregnating the base material in the antistatic impregnation liquid; and (4) drying impregnated products. The antistatic sound absorption paper has the advantages of sound absorption, flame retardance and antistatic performance, is applied to places such as movie theaters, music halls, lecture halls and conference rooms and, has excellent sound absorption effect, and can be also used for avoiding potential safety hazards caused by fire hazards and the like due to static electricity. The antistatic agent is added in the impregnation liquid, and the antistatic sound absorption paper is manufactured by an impregnation treatment method, thus the preparation process is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing paper and its preparation, in particular to antistatic sound-absorbing paper and its preparation method. Background technique [0002] With the improvement of the quality of life and the enhancement of environmental awareness, people's demand for sound-absorbing materials that can reduce environmental noise is increasing. At present, common sound-absorbing materials include sound-absorbing cotton, sound-absorbing non-woven fabric, and sound-absorbing paper. These sound-absorbing materials are mostly made of plant fibers, chemical fibers and inorganic glass fibers. The above-mentioned various fibers are all insulators and have relatively large resistance. The sound-absorbing materials made of the above-mentioned fibers often generate static electricity due to friction during use and processing, especially in a dry environment. The generation of static electricity may not only affect the n...
