Preparation method and construction method of diatom ooze environment-friendly wall material for building decoration

Abstract

The invention relates to the field of preparation of environment-friendly wall materials, and discloses a preparation method and a construction method of a diatom ooze environment-friendly wall material for building decoration. The preparation process comprises the following steps: (1) supporting sodium carbonate powder; (2) preparing an capsule material emulsion; (3) preparing diatomaceous earth,nano ferrite and the capsule material emulsion into a mixed solution; (4) carrying out drying at a constant temperature to obtain microcapsules; and (5) uniformly dispersing and mixing the microcapsules with glass fibers, a coupling agent, a binding agent, active clay and pigment. The construction method comprises the following steps: (1) preparing a paste-like coating, and brushing a wall surface with the paste-like coating; (2) applying a high-frequency alternating magnetic field; (3) spraying a citric acid solution; and (4) carrying out drying. According to the invention, through the addition of the high-frequency alternating magnetic field, magnetic particles embedded into a capsule material generate a magneto-thermal effect, and the temperature-sensitive capsule material is induced to be broken rapidly, so that the construction condition of the diatom ooze is improved. The diatom ooze wall material releases sodium carbonate to react with citric acid, and gas is generated, so thatthe pores of the diatomaceous earth are prevented from being blocked, and the adsorption and purification effects are remarkably improved.

Description

technical field [0001] The invention relates to the field of preparation of environment-friendly wall materials, and discloses a preparation and construction method of diatom mud environment-friendly wall materials for architectural decoration. Background technique [0002] Indoor environmental pollution caused by construction, decoration and furniture has become a major killer affecting people's health. According to the data provided by the China Indoor Environmental Monitoring Center, the number of excess deaths caused by indoor air pollution in my country can reach 111,000, the number of excess outpatient visits can reach 220,000, and the number of excess emergency visits can reach 4.3 million. From the current detection and analysis, the main sources of indoor air pollutants are as follows: building and interior decoration materials, outdoor pollutants, combustion products and human activities. Among them, the pollution of interior decoration materials and furniture is ...

Problems solved by technology

[0007] According to the above, there are some defects in the diatom mud in the existing scheme, such as low strength, easy to drop powder, easy to crack, etc., in order to solve these problems, organic colloids are often added to the diatom mud wall material. The residual solvent has a strong smell, and it is easy to block the pores of diatomite, which greatly reduces its adsorption performance and reduces the environmental protection function of diatom mud coating to a large extent. The present invention proposes a preparation of diatom mud environmental protection wall material for architectural decoration and construction methods can effectively solve the above technical problems
