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 system for manufacturing a multi-component high molecular polymer fiber sound-absorbing heat-insulating material. The system mainly comprises a chopped fiber hybrid-combing device, a melt-blown hybrid-forming device, a surface-enhancing treatment device and a coiling machine. The system is clear in structure principle, and the manufactured multi-component high molecular polymer fiber sound-absorbing heat-insulating material has excellent uniformity, air permeability, tensile strength, elastic recovery rate and sound-absorbing and heat-insulating efficiency.

Description

technical field [0001] The invention relates to a manufacturing system of a multi-component polymer fiber sound-absorbing and heat-preserving material, which belongs to the field of noise reduction and non-woven engineering. 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 polyurethane foam c...
