Embodiment Construction

[0014] A sound-absorbing cotton with air purification effect, which is made from the following raw materials in parts by weight:

[0015] Polyester fiber 40, jute fiber 10, straw fiber 10, ES fiber 10, egg shell powder 2, herb 1, lily 0.5, perrin 0.5, silane coupling agent KH-5501, camphor oil 0.3, composite resin 10, coconut oil 1;

[0016] Wherein the composite resin is made of the following raw materials in parts by weight: acrylamide 8, vinyl acetate 4, potassium persulfate 0.05, polysorbate-800.1, sodium lauryl sulfate 0.5, aluminum chloride 1.5, sodium bicarbonate 4, Water 40; The preparation method of composite resin is to first add acrylamide, vinyl acetate, sodium lauryl sulfate, polysorbate-80 and aluminum chloride into water and stir for 5min, then add potassium persulfate and under nitrogen protection 50 ℃ for 0.5h, and finally add sodium bicarbonate to continue the reaction for 2h, wash and grind evenly to obtain the product.

[0017] A preparation method of soun...

Abstract

The invention discloses sound absorption cotton having an air purification function. The sound absorption cotton is prepared by adopting the following raw materials in part by weight: 40 to 60 parts of polyester fibers, 10 to 15 parts of jute fibers, 10 to 15 parts of straw fibers, 10 to 15 parts of ES fibers, 2 to 4 parts of eggshell powder, 1 to 2 parts of rhizoma atractylodis, 0.5 to 1 part of lily, 0.5 to 1 part of eupatorium, 1 to 2 parts of silane coupling agent KH-550, 0.3 to 0.5 parts of camphor oil, 10 to 15 parts of composite resin and 1 to 2 parts of coconut oil. The sound absorption cotton has a better full-range sound absorption function, can obviously improve the acoustic performance, also can purify the air and kill the bacteria, and is favorable for keeping the environment clean and sanitary, good in application performance, wide in application range and high in practicability.

Description

technical field [0001] The invention relates to the technical field of sound absorption, in particular to a sound-absorbing cotton with air purification function 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...
