Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly rubber sound-insulating building material and a preparation method thereof. Background technique [0002] Now, with the continuous acceleration of urbanization, noise pollution is becoming more and more serious. In order to effectively cut off noise, the usual solution is to use soundproofing materials. Existing sound insulation materials are generally cement concrete, glass panels, etc., these sound insulation and so on. The sound insulation effect of these sound insulation materials is not very good, so the usual solution is to increase the thickness of the sound insulation materials. The problem caused by this is that the quality of the sound insulation material is too heavy, the cost is too high, and the installation process is very inconvenient. Polypropylene-based composite non-woven materials made by meltblown method have become a kind...
