Problems solved by technology

The damping effect of a single polymer is not good, and it is difficult to meet the actual requirements, but the noise reduction performance of multi-components can be improved by modifying, adding fillers, etc.
[0006] Chinese patent announcement number CN 108911688A discloses a new type of fireproof and soundproof building material and its preparation method, which is composed of the following raw materials in weight percentage: cement, mica powder, shell powder, attapulgite, modified kaolin, modified fly ash, Water reducing agent, water, vitrified hollow microspheres, expanded perlite, ceramic fiber, glass fiber filament, adhesive A, sponge scraps, wood chips, adhesive B, flame retardant, the new building material is prepared with good sound absorption The effect of noise reduction, environmental protection and pollution-free, but this preparation method requires more raw materials, the preparation process is complicated, increases the production cost, and is not conducive to large-scale production
The construction materials prepared by this method use materials such as sludge waste and straw fragments, which are environmentally friendly and energy-saving while meeting the noise reduction performance. However, due to the excessive use of inorganic waste and plant waste, the mechanical strength of the formed material is weak. Poor, the durability is not enough, at the same time, firing the shaped building materials consumes a lot of energy, which is not conducive to large-scale industrial production
[0008] It can be seen that there are many formulas and methods of using waste materials to prepare sound-insulating building materials in the prior art, but most of them have insufficient mechanical properties and sound-insulating effects. The present invention aims to propose a solution to the defects in the prior art
