Problems solved by technology

[0002] With the rapid development of the world economy, the continuous improvement of people's living standards, the rapid development of the automobile industry, the rapid development of car production, and the continuous updating of models, people's requirements for cars are not only beautiful appearance, but also comfort and functionality of interior decoration. , Environmental protection performance also puts forward new requirements, but in order to achieve a certain degree of hardness and shape performance, the commonly used car interior carpets on the market often contain chemical latex. In order to prevent the carpet from foaming and breakdown, interior carpet materials It usually contains chemical EPDM and EVA coatings. The above chemical latex, EPDM and EVA chemical raw materials contain high toxic and irritating odors such as formaldehyde, and the commonly used car interior carpets on the market have poor sound insulation performance, and the noise when the car is running Relatively large, therefore, the automotive interior carpets on the market can not meet people's standards for comfort and environmental protection

Embodiment 1

[0020] Preparation of the fabric layer: Take polyester fibers with a weight percentage of 90:10 and fibers with a melting point of 100°C to open and mix them evenly to obtain fibers of a certain color and specification, and then transport the fibers to the carding machine through a material box. The fiber web is obtained by high-speed carding, and the fiber web is then passed through a cross-lapper to form a fiber web of 250 g / m2, and then the fiber web is transported to the needling machine, with a needling depth of 10mm and a needling speed of 3m / min. Acupuncture is carried out according to the conditions, and the fabric layer with an acupuncture density of 120 needles / square centimeter is obtained for subsequent use.

[0021] The preparation of the bottom material layer: take the polyester fiber with a weight percentage of 75:25 and the fiber with a melting point of 100°C to open and mix evenly to obtain fibers of a certain color and specification, and then transport the fib...

Embodiment 2

[0024] The preparation of the fabric layer: take the polyester fiber with a weight percentage of 92:8 and the fiber with a melting point of 110°C to open and mix evenly to obtain fibers of a certain color and specification, and then transport the fibers to the carding machine through the material box. The fiber web is obtained by high-speed carding, and the fiber web is then passed through a cross-lapper to form a fiber web of 430 g / m2, and then the fiber web is transported to the needling machine, with a needling depth of 13mm and a needling speed of 5m / min. Acupuncture is carried out according to the conditions, and the fabric layer with an acupuncture density of 500 needles / square centimeter is obtained for subsequent use.

[0025] Preparation of the bottom material layer: Take polyester fibers with a weight percentage of 45:55 and fibers with a melting point of 110°C to open and mix them evenly to obtain fibers of a certain color and specification, and then transport the fi...

Abstract

The invention discloses a composite sound-proof formed foaming automobile carpet and a preparation method thereof. The carpet is made of three layers of materials, namely a fabric layer, a middle multi-layer co-extrusion film layer and a bottom material layer, wherein the fabric layer is made of polyester fiber; the middle multi-layer co-extrusion film layer is made of PE / PE / AD / NYLON / AD / PE / PE multi-layer co-extrusion films; and the bottom material layer is made of polyester fiber. The sound-proof formed foaming automobile carpet provided by the invention has good sound insulation effect, can effectively prevent PU foaming breakdown, and has no toxic odor such as formaldehyde and the like and no penetrating odor; the fabric of the carpet has elegant color and the loop appearance can be adjusted; and the composite sound-proof formed foaming automobile carpet is an environment-friendly carpet with high sound insulation performance. The method for preparing the composite sound-proof formedfoaming automobile carpet provided by the invention has simple process, high efficiency, strong operability, high qualification rate of finished products, and can be suitable for mass production.
