Problems solved by technology

At the same time, the side effect of high technology—noise pollution is becoming more and more serious. The existing sound insulation materials not only have poor sound insulation effect, high energy consumption of materials, but also have volatile pollutants, which are easy to cause environmental pollution. Therefore, There is an urgent need to improve the material formula and process to improve the performance of the sound insulation board and reduce pollution

Abstract

The invention discloses an environment-friendly soundproof material. The environment-friendly soundproof material is prepared from, by weight, 60-70 parts of polyethylene, 20-25 parts of natural fiber, 18-25 parts of allyl phenyl isopentene ether, 10-15 parts of calcium carbonate, 5-8 parts of starch phosphate monoester, 2-6 parts of polyoxyethylene stearate, 3-5 parts of polyglycerol fatty acid ester, 2-5 parts of sodium silicate, 1-3 parts of sodium hydrogen carbonate, 1-2 parts of di(2-chloroethyl) dichloride phosphamide, 1-2 parts of cetanethiol and 0.2-0.8 part of diamyl succinic acid sodium sulfonate. The invention further provides a preparation method of the environment-friendly soundproof material.

Description

Technical field [0001] The invention belongs to the field of sound insulation materials, and particularly relates to an environment-friendly sound insulation material and a preparation method thereof. Background technique [0002] With the development of technology, public transportation has become more developed, and people's travel has become faster and faster. At present, high-speed railways and highways have greatly improved people's travel efficiency. At the same time, the side effect brought by high technology-noise pollution is becoming more and more serious. The existing sound insulation materials not only have poor sound insulation effect, but also high energy consumption of materials, but also contain volatile pollutants, which are easy to cause environmental pollution. It is urgent to improve the material formula and process to improve the performance of the sound insulation board and reduce pollution. [0003] Polyethylene (PE) is a thermoplastic resin made by polymer...
