Abstract

The invention relates to a recycled noise pollution control material and a preparation method thereof and belongs to the technical field of acoustic materials. 20-25 parts of jute fiber, 40-50 parts of carbonized powder, 100-120 parts of waste plastics, 0.1-0.3 parts of macromolecular coupling agent hydrolysate and 1-3 parts of a plasticizer are added to a high-speed multifunctional pulverizer to be mixed uniformly, then the obtained mixture is put into an internal mixer to be mixed and transferred to a double-screw extruder to be extruded and granulated, and the recycled noise pollution control material is prepared. The waste plastics and plant waste are adopted as recycled materials, the utilization value of the waste plastic and deep processing and utilization of the plant waste are effectively improved, recycling of biomass materials is realized, pollution caused by polymer waste is reduced, the low-cost noise pollution control material product can be provided, and the material and the method have good environmental benefits and economic value.

Description

technical field [0001] The invention relates to a regenerative noise pollution control material and a preparation method thereof, belonging to the technical field of acoustic materials. Background technique [0002] Noise pollution, air pollution, and water pollution are the three main pollution sources in contemporary times. Noise pollution is a kind of physical pollution, which directly acts on the senses of the human body, but it has no aftereffect, that is, when noise pollution occurs, people can feel it immediately, and when it stops, the noise pollution disappears immediately. Therefore, the harm of noise pollution is easily overlooked by people. Excessive noise and vibration will not only affect people's normal work and rest, reduce work efficiency, but also damage people's health. With the improvement of people's awareness of the living environment, people's requirements for a comfortable environment are also getting higher and higher, so the control of noise pollu...
