Abstract

The invention discloses Muyu stone powder modified composite sound-absorbing cotton. The sound-absorbing cotton is prepared from, by weight, 40-60 parts of polyester fibers, 20-30 parts of hemp fibers, 5-10 parts of jade fibers, 10-15 parts of ES fibers, 0.5-1 part of sodium diethylhexyl sulfosuccinate, 1-2 parts of silane coupling agents KH-550, 2-3 parts of Muyu stone powder, 1-2 parts of pyrophyllite powder, 0.3-0.5 part of polyethylene glycol monostearate, 2-4 parts of soybean oil and 10-15 parts of composite resin. The sound-absorbing cotton has better full frequency sound absorbing capability, the acoustic performance is improved obviously, the health-care performances of bacteriostasis, human immunity improvement and aging resistance are achieved, the use performance is good, and the practicability is great.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing technology, in particular to a composite sound-absorbing cotton modified with wood fish stone powder 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 performanc...
