Abstract

The invention relates to the technical field of carpets, and in particular relates to a carpet with silencing and denoising functions and a preparation method of the carpet. The carpet with silencingand denoising functions comprises a wear-resistant layer, a first hot melt adhesive net layer, a sound absorbing layer, a second hot melt adhesive net layer and a weaving layer which are arranged in the sequence from bottom to top, wherein a plurality of anti-skidding bulge parts distributed at intervals are arranged below the wear-resistant layer, the upper ends of the anti-skidding bulge parts are connected with the lower surface of the wear-resistant layer, the weaving layer is formed by weaving warp weaving yarns and weft weaving yarns, and the sound absorbing layer is a polyester fiber sound absorbing layer. For the carpet with the silencing and denoising functions provided by the invention, through the compounding of the wear-resistant layer, the first hot melt adhesive net layer, the sound absorbing layer, the second hot melt adhesive net layer and the weaving layer, the prepared carpet has good silencing and denoising effects, through the wear-resistant layer and the anti-skidding bulge parts, the skid resistance and wear resistance of the carpet are improved, in addition, the connection among all the layers is stable, so that the service life of the carpet is long, moreover, the preparation method is simple and efficient, the operation process is easy to control, the industrial production is benefited, and the prepared product is stable in quality.

Description

technical field [0001] The invention relates to the technical field of carpets, in particular to a silent and noise-reducing carpet and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of living standards, carpets have been increasingly used more widely. However, the existing blankets have poor sound-absorbing and noise-reducing functions, cannot effectively absorb the noise in the use occasion, and the connections of each layer are not tight, the waterproof and wear resistance is not good, and the service life is low, which affects its use. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a silent and noise-reducing carpet, which has a good function of silent and noise-reducing, and has a simple structure, good anti-skid and wear resistance, long service life, and practical high sex. Another object of th...
