AI Technical Summary

Problems solved by technology

Ordinary polyester fiber sound-absorbing cotton has a narrow sound-absorbing bandwidth, and only has a good absorption of medium and high-frequency sounds, and has limited absorption effect on low-frequency sounds.
At the same time, excessive ultraviolet rays will cause some photochemical reactions, which will affect the performance, service life and human health of the material, while ordinary sound-absorbing cotton has no anti-ultraviolet effect

Abstract

The invention discloses ultraviolet-proof sound-absorbing cotton, prepared from the following materials in parts by weight: 40 to 60 parts of polyester fiber, 5 to 10 parts of acrylic fiber, 20 to 30 parts of bamboo fiber, 10 to 15 parts of ES fiber, 1 to 2 parts of a silane coupling agent KH-550, 0.05 to 0.1 parts of 2, 4-dihydroxy benaophenonel, 0.3 to 0.5 parts of caprylic capric triglycerride, 0.2 to 0.4 parts of diacetin, 3 to 5 parts of tea-seed oil, 0.3 to 0.5 parts of nano-zinc oxide, 1 to 2 parts of styrene-acrylic emulsion and 10 to 15 parts of composite resin. The sound-absorbing cotton has better all-frequency sound-absorbing capacity, obviously improved acoustic performance and an ultraviolet-proof effect, and is capable of effectively preventing ultraviolet ray penetration, good in usability, wide in application scope and high in practicability.

Description

technical field [0001] The invention relates to the technical field of sound absorption, in particular to an anti-ultraviolet sound-absorbing cotton and a preparation method thereof. Background technique [0002] In today's society, noise pollution has become one of the major environmental pollution problems that have attracted worldwide attention after water pollution and air pollution. The use of sound-absorbing and sound-insulating materials for sound insulation and noise reduction is a common means of controlling noise pollution. At present, the commonly used sound-absorbing cotton on the market includes glass fiber sound-absorbing cotton, sponge, polyester fiber sound-absorbing cotton, etc. Glass fiber cotton is easy to cause skin itching and respiratory allergies, which is harmful to the human body and is not suitable for indoor use. Most of the sponge is a closed-cell foam material, which has limited sound absorption performance and is more suitable for thermal insu...
