Problems solved by technology

Generally, in the prior art, particles of the same particle size are used for filling, and it is difficult to achieve volume complementation and uniform distribution, resulting in uneven filling and poor mechanical properties, which affect the sufficient reflection, scattering, refraction and diffraction of sound waves in it, thus Affects the blocking and absorption of sound
When all large-size particles are used, it is difficult to achieve dense filling due to the steric hindrance effect, and the gaps between the particle

Description

technical field [0001] The invention belongs to the technical field of preparation of thermoplastic resin sound insulation materials, and in particular relates to a thermoplastic resin sound insulation material and a preparation method thereof. Background technique [0002] At present, the development of industrial technology has brought convenient transportation, prosperous urban life and row upon row of factories to people, but the noise pollution is becoming more and more serious. The ubiquitous factory noise (up to more than 100 decibels), entertainment noise, construction noise and traffic noise are increasingly affecting our daily life. On the other hand, with the improvement of living standards, people have higher and higher requirements for the quiet comfort and mutual non-interference of living environment, working and learning environment, entertainment environment and public places. Therefore, noise control and blocking has become an important problem to be solve...
