Abstract

The invention relates to the field of sound insulation cottons, and especially relates to a compound sound insulation cotton. The compound sound insulation cotton comprises an upper waterproof layer, a middle sound insulation layer and a lower flame retardation layer; and the upper waterproof layer comprises, by weight, 12-22 parts of acrylate, 25-45 parts of quartz sands, 9-18 parts of petroleum resin, 0.5-2 parts of hydroxypropyl methyl cellulose ether, 3-5 parts of 4,6-dihydroxypyrimidine, 1-20 parts of asphalt and 3-6 parts of nanometer graphene. The sound insulation cotton is designed to have an upper layer, a middle layer and a lower layer, the upper layer is waterproof, the middle layer isolates sounds, and the lower layer is flame-retardant, so the sound insulation cotton has a waterproof function and a heat insulation function, and has greatly improved practicality.

Description

technical field [0001] The invention relates to the field of sound-insulating cotton, in particular to a composite sound-insulating cotton. Background technique [0002] The noise generated by the car when it is idling, accelerating or driving on different road surfaces will be amplified and transmitted into the car after the chassis and car body resonate or resonate, making the driver and passengers feel uncomfortable. The sound insulation cotton can convert the noise vibration energy into the kinetic energy of the fine denier fiber inside the sound insulation cotton and then conduct it into heat energy and disappear, so as to achieve the function of sound absorption and noise reduction. Therefore, the sound insulation cotton quilt is widely used in the automobile manufacturing industry, but the existing sound insulation cotton is Without flame retardant performance, the sound insulation cotton will burn in case of fire, causing major disasters.
