Problems solved by technology

It is difficult to increase the content of short polyester fibers in the material, because the tensile properties are greatly reduced, making it difficult to shape the material during the manufacturing process; if it is increased, the sound absorption performance will be greatly improved due to the large number of coarse denier fibers in the material. discount
These are the performance obstacles of the existing sound-absorbing and thermal insulation materials based on the melt blown method and the problems that are difficult to solve in the manufacturing process.

Abstract

The invention discloses a multi-component high-molecular polymer fiber sound-absorbing insulation material and a production method thereof. The sound-absorbing insulation material is a multi-layer mixture comprising superfine melt-blown fibers, various different linear densities artificial or natural three-dimensional crimp short fibers, low melting point short fibers, and a surface reinforced layer. The multi-component high-molecular polymer fiber sound-absorbing insulation material has excellent uniformity, permeability, tensile strength, elastic recovery rate, sound-absorbing and insulation efficiency, and environmental protection performance, and can be widely applied to the fields of noise reduction and insulating engineering in automobile, airplane, rail vehicle, steamship and other vehicles, building industry and other industries.

Description

technical field [0001] The invention relates to the field of noise reduction and non-woven engineering, in particular to a multi-component polymer fiber sound-absorbing and heat-insulating material and a manufacturing method thereof. Background technique [0002] At present, noise-reducing and shock-absorbing materials used in the construction industry, automobiles, rail vehicles, ships and other transportation vehicle manufacturing industries are divided into: sound-absorbing materials, barrier materials and damping materials, among which the most widely used in sound-absorbing materials There are felts, inorganic fibers, polymer foams and other materials, all of which have various defects in material properties. For example, the defects of felts are low sound absorption efficiency per unit weight, strong water absorption, easy to mold, harmful volatilization Inorganic fibers such as glass fiber cotton fiber dust are harmful to human health; polymer foams such as polyuretha...
