Problems solved by technology
[0002] With the improvement of people's living standards, the requirements for environmental noise are becoming more and more stringent, the use of sound-absorbing materials is increasing, and the use of places is becoming wider and wider. Among them, sound-absorbing porous materials mainly composed of cotton fiber or glass fiber are used in automobiles, It is the most widely used in architectural decoration, etc., but the sound-absorbing materials based on cotton fibers have poor anti-mold, anti-bacterial and anti-corrosion performance in harsh environments, and the sound-absorbing materials based on glass fibers are easy to cause skin allergies and are harmful to human health. It is necessary to study a fiber-like porous material with superior performance that can be used in high and low temperature, humid and corrosive environments. Carbon fiber not only has superior performance, but also has the softness and processability of textile fibers. It is used as a new generation of high-performance fibers in In terms of sound-absorbing materials, its prospects cannot be underestimated. Carbon fiber chopped strands are bundled, light in weight, smooth, and difficult to disperse. Carbon fibers cannot be curtained in the inclined curtain conveying structure, and they do not have the production conditions for felting.

Abstract
The invention discloses a carbon fiber-based sound-absorbing material and a preparation method thereof. The formula of the sound-absorbing material is as follows: by weight percentage, it includes 10-40% of carbon fiber chopped strands, 30-50% of hollow porous carbon fiber pre-oxygenated yarns and low melting point Fiber 20‑50%, the above three kinds of fibers are opened and mixed, processed into a fiber web, heated to melt the low melting point part, cooled, and obtained. The present invention adopts the method of mixing three kinds of fibers, and provides a processable preparation method of carbon fiber by optimizing the fiber properties and proportions. The prepared sound-absorbing material has light weight, high strength, anti-mold, anti-bacteria and heat resistance. Excellent performance.
