The invention belongs to the technical field of coatings, and particularly relates to a water-based sound insulation
coating for ground sound insulation and shock absorption, and a preparation methodthereof. The
coating comprises an
emulsion, a filler, aggregates, a
halogen-free
flame retardant, a defoaming agent, a bactericide, a
thickening agent, a dispersing agent and deionized water, and further comprises rubber particles and rubber fibers. The
coating of the invention has better flowability, film-forming property, sound insulation property, damping property and shock absorption propertythan coatings in the prior art, and is better than other sound insulation coatings with the same thickness; the sound insulation coating can achieve A1-level
fire prevention, and has the advantages ofenvironmental friendliness, no
pollution, good protecting effect on buildings, good
adhesive force, good permeability, good compatibility with a base material, and no crack; the production technologyof the coating has the advantages of simplicity, easiness in implementation, improvement of the performances of the coating through reasonable dispersion and mixing of all the components, simplicityin construction operation, avoiding of node treatment with complex procedures, reduction of cross operation, reduction of the procedures of other traditional floor sound insulation methods by at least50%, and high
cost performance.
