Antibacterial sound-absorbing cotton for automobile

Abstract

The invention relates to antibacterial sound-absorbing cotton for an automobile. The sound-absorbing cotton comprises felt made of polyester fiber and polypropylene fiber, an aldehyde eliminating layer for eliminating aldehyde substances contained in a binder is coated outside the polyester fiber and the polypropylene fiber, the polyester fiber and/or the polypropylene fiber is curly fiber of a hollow structure, the polyester fiber is obtained by fusing and blending polyester slice and polyester masterbatch, and the polyester masterbatch is obtained by mixing and granulating multifunctional filler and polyester power; the multifunctional filler is composed of Ca-ZnO nanoparticles, TiO nanoparticles, CuO nanoparticles, shell powder, MnO2 particles and Al2O3-In2O3 particles.

Description

technical field [0001] The application relates to the technical field of automobile environmental protection materials, in particular to an antibacterial sound-absorbing cotton used in automobiles. Background technique [0002] Car sound-absorbing cotton materials have a wide range of applications in car design and assembly, and have the characteristics of sound absorption, noise reduction, and environmental protection. However, due to its fiber structure and cost constraints, more sound-absorbing cotton materials use recycled materials or phenolic resin and other binders, which have an impact on the environmental pollution in the car. At present, the quality of the air quality in the car on the market will directly affect the driving comfort of the vehicle, and in severe cases, it will also cause physical and mental harm to the drivers and passengers. At present, in the industry, there are many ways to reduce or replace the use of sound-absorbing cotton materials or to use...
