Abstract
The invention discloses modified calcium carbonate serving as a sound absorbing filler. The modified calcium carbonate is characterized by being prepared from the following raw materials in parts by weight: 90-95 parts of calcium carbonate, 4-6 parts of nanometer hollow microspheres, 3-5 parts of aluminum silicate fiber cotton, 3-4 parts of zizania aquatica straw powder, 2-4 parts of expanded perlite, 3-4 parts of activated aluminum oxide, 2-3 parts of ammonium carbonate, 6-8 parts of polycarbonate, 5-6 parts of natural latex, 1-2 parts of alpha-vinyl sodium sulfonate and 3-4 parts of modified titanium dioxide. The modified calcium carbonate disclosed by the invention has excellent sound absorption performance due to addition of the nanometer hollow microspheres and the aluminum silicate fiber cotton, has a large specific surface area as well as sound absorption and adsorption effects due to addition of plant fibers and natural substances, and has increased dispersion performance due to addition of the modified titanium dioxide, so the modified calcium carbonate is applicable to production of additives including sound absorbing bricks, sound absorbing plates, coatings and the like.
