Multifunctional diatom ooze

The invention discloses multifunctional diatom ooze. The multifunctional diatom ooze is prepared by comprising the following steps: compounding vinyl acetate-VAE copolymer emulsion with silica sol into a film forming matter according to mass ratio of 1:1; by taking diatomite as a humidifying filler, macromolecular water-absorbent resin as a humidifying agent, phase-change energy-accumulating microcapsules as an energy-accumulation thermoregulation filler and anion antibacterial additive as an antibacterial mouldproof material, stirring and mixing by conventional coating production equipment under the matching of various auxiliaries. The multifunctional diatom ooze has multiple functions of automatically regulating and controlling the temperature, absorbing and dissipating moisture, resisting bacteria and mould, refreshing air, removing harmful gas, releasing negative ions, is sound-proof, reducing noise and is ecological and environment-friendly, and is capable of lowering the interior temperature by about 3 DEG C in summer, and increasing the interior temperature by about 2 DEG C in winter, so that the electricity of an air conditioner can be saved by 30% in summer, and the warming energy consumption can be saved by 20% in winter, and the multifunctional diatom ooze has good popularization and application prospects.
