Embodiment 1

[0021] Example 1 proposes a carbon fiber thermal insulation and sound-absorbing cotton, which includes the following raw materials in parts by weight: 60 parts of carbon fiber and 40 parts of polyester fiber.

[0022] The preparation method of the carbon fiber thermal insulation and sound-absorbing cotton in Example 1 comprises the following steps: after mixing the raw materials, opening, cotton feeding, and carding are carried out in sequence, and then paved to a thickness of 20 mm and a grammage of 350 g / m 2 The net is then penetrated with hot air at 90°C for 60 minutes and then cooled to room temperature to obtain carbon fiber thermal insulation and sound-absorbing cotton.

Embodiment 2

[0024] Example 2 proposes a carbon fiber thermal insulation and sound-absorbing cotton, which includes the following raw materials in parts by weight: 95 parts of carbon fiber and 5 parts of polyethylene terephthalate fiber.

[0025] The preparation method of the carbon fiber thermal insulation and sound-absorbing cotton in Example 2 comprises the following steps: after mixing the raw materials, opening, cotton feeding, and carding are carried out in sequence, and then paved to a thickness of 25mm and a grammage of 250g / m 2 The net is then penetrated with hot air at 280°C for 3 minutes and then cooled to room temperature to obtain carbon fiber thermal insulation and sound-absorbing cotton.

Embodiment 3

Abstract

The invention relates to carbon fiber heat preservation and sound absorption cotton and a preparation method and application thereof. The cotton is prepared from, by weight, 60-95 parts of carbon fiber and 5-40 parts of polyester fiber. The carbon fiber heat preservation and sound absorption cotton can effectively lower noise, the advantages that the carbon fiber has no melting point and is not burnt are sufficiently utilized, the physical property that the polyester fiber has a melting point is sufficiently utilized, the ratio of the cotton to the polyester fiber is adjusted, the cotton and the polyester fiber are organically combined, the carbon fiber heat preservation and sound absorption cotton is manufactured through a series of physical changing processes, and the carbon fiber heat preservation and sound absorption cotton is environmentally friendly, comfortable and good in heat preservation and sound absorption effects and is of great guiding significance in follow-up traffic noise abatement work.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a carbon fiber thermal insulation and sound-absorbing cotton and its preparation method and application. Background technique [0002] Car noise directly affects people's physical and mental health and the improvement of quality of life. Long-term exposure to noise can cause hearing loss and even induce some diseases. Tests have shown that: 80 decibels will reduce the driver's attention by 10%, and 20% at 90 decibels. To stay away from noise, all we can do is sound absorption and sound insulation. The sound-absorbing cotton can convert the medium and high-frequency noise vibration energy generated by the vibration of the car body into the kinetic energy of the fine denier fibers inside the sound-absorbing cotton, and convert it into heat energy and dissipate it to achieve the function of sound absorption and noise reduction. [0003] The existing product...
