preparation example Construction

[0045]In a specific embodiment, the preparation method of the protein earth-based inorganic environmental protection material prepared by the present invention includes the following steps:

[0046](1) Accurately weigh each component according to the formula, accurate to 0.01g;

[0047](2) Mix the white Portland cement and wood fiber, place it in a high-speed disperser, and rotate at 2000r / min for 10s to completely disperse the clumps in the white cement, so that the wood fiber is evenly dispersed in the white silicate In the cement, the first material is obtained;

[0048](3) Mix the first material with water-retaining agent, air-entraining agent, and water-repellent agent, and rotate in a high-speed disperser at 1000r / min for 10s to obtain a uniformly dispersed second material;

[0049](4) The second material is mixed with 20-40 mesh protein soil particles, 80-120 mesh protein soil particles and sepiolite fibers in a two-dimensional mixer at 200r / min for 15-20min to mix the components evenly ...

Abstract

The invention discloses a protein soil-based inorganic environmental protection material with sound-absorbing and noise-reducing functions, as well as a preparation method and a construction method thereof. The protein soil-based inorganic environmental protection material includes the following components by mass: 15-25 parts of 20-40 mesh protein soil particles, 15-40 parts of 80-120 mesh protein soil particles, 10-25 parts of white Portland cement, Sepiolite fiber 20-50 parts, wood fiber 0.4-1.5 parts, water-repellent agent 0.05-0.80 parts, air-entraining agent 0.05-0.80 parts, water-retaining agent 0.5-1.5 parts. After the material and the construction method of the present invention are used for construction, the finished product is simple and elegant, has a strong noise elimination effect, and satisfies people's requirements for sound absorption and noise reduction of materials.

Description

Technical field[0001]The invention belongs to the field of building interior wall decoration wall materials, and more specifically relates to a protein soil-based inorganic environmental protection material with sound absorption and noise reduction functions, and a preparation method and construction method thereof.Background technique[0002]In modern life, noise pollution has become more and more serious. Noise pollution has become a major pollution problem after air, water, and solid waste pollution, which seriously endangers people's physical and mental health. People are paying more and more attention to the quietness of the environment, so sound-absorbing and noise-reducing materials are often used in interior decoration.[0003]Most of the sound-absorbing materials are loose and porous materials, such as slag wool, blankets, etc. The sound-absorbing mechanism is that the sound wave penetrates into the pores of the material, and the pores are mostly open pores intersecting each ot...
