Embodiment Construction

[0025] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the examples. The following examples are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0026] The mass parts of each component of the sound-absorbing and shock-absorbing polyester composite cotton provided in Examples 1-3 are shown in Table 1, and the preparation method is carried out according to the following steps:

[0027] 1. Weighing and feeding: Weigh hollow polyester fibers with a mass percentage of 50% to 80% and hot-melt fibers with a mass percentage of 20% to 50% whose melting point is lower than 150°C, and put them into the cotton blending and opening equipment. The fiber fineness of polyester fibers and hot-melt fibers with a melting point below 150°C is 3 deniers to 15 deniers;

[0028] 2. Cotton blending and opening: under the s...

Abstract

The invention discloses sound absorption and vibration reduction polyester composite cotton, which is formed by mixing 50 percent to 80 percent of hollow polyester fibers with 20 percent to 50 percent of meldable fibers with the melting point lower than 150 DEG C through being metered by the mass percent. The sound absorption and vibration reduction polyester composite cotton disclosed by the invention has the advantages that the weight is light, the environment is protected, the composite cotton is nonflammable, the heat conductivity coefficient is small, sound absorption, sound isolation, vibration reduction and water resistance are realized, the maintenance is convenient, the secondary recovery can be realized, the production quality is stable, and the likes. Meanwhile, the invention also discloses a preparation method of the sound absorption and vibration reduction polyester composite cotton.

Description

technical field [0001] The invention relates to the technical field of composite sound-absorbing and shock-absorbing pad materials, in particular to a sound-absorbing and shock-absorbing polyester composite cotton and a preparation method thereof. Background technique [0002] Sound-absorbing and shock-absorbing materials are indispensable components for the production of automotive interior parts, such as carpet sound insulation pads, front wall sound insulation pads, ceiling sound insulation pads, shock-absorbing cushions, trunk sound insulation pads, door panel sound insulation pads, wheel cover sound insulation pads, The manufacture of air duct sound insulation pads, coat rack sound insulation pads and other accessories all belong to the application scope of sound-absorbing and shock-absorbing materials. In the prior art, common sound-absorbing and shock-absorbing materials mainly include cotton felt, foam sponge, and glass fiber. Environmental performance and other asp...
