The invention discloses an environment-friendly sound-insulation, heat-insulation, waterproof and weather-resisting material and a preparation method thereof. The environment-friendly sound-insulation, heat-insulation, waterproof and weather-resisting material is prepared from the following raw materials in parts by weight: 15 to 20 parts of modified filling soil, 6 to 8 parts of enhanced fibers,5 to 7 parts of sound-absorption filler, 3 to 5 parts of nano additive, 5 to 9 parts of
silicon dioxide
sol, 20 to 26 parts of mineral
powder filler, 9 to 11 parts of acrylic
emulsion, 5 to 7 parts ofadhesion auxiliary agent, 3 to 5 parts of
coupling agent, 3 to 5 parts of
calcium carbonate powder and 4 to 6 parts of
flame-retarding additive. The environment-friendly sound-insulation, heat-insulation, waterproof and weather-resisting material has excellent sound-insulation and
noise-reduction effects, relatively good heat-insulation and waterproof performance and excellent
wear resistance andcompression resistance, and does not volatilize harmful substances; furthermore, the environment-friendly sound-insulation, heat-insulation, waterproof and weather-resisting material also has certainadsorption performance and has the effect of purifying
indoor air; meanwhile, the preparation method of the sound-insulation material has the advantages of relatively low cost, easiness for obtainingthe raw materials, simple technology, easiness for operation and easiness for realizing industrial production, and has relatively high practical value and a good application prospect.
