Environment-friendly diatom ooze composite and preparation method thereof

The invention discloses an environment-friendly diatom ooze composite and a preparation method thereof, and belongs to the technical field of composites for buildings. The environment-friendly diatom ooze composite is prepared from, by mass, 30-50% of diatomite, 3-12% of heavy calcium powder, 8-20% of quartz sand, 10-15% of pH conditioning agents, 6-10% of calcined kaolin, 4-10% of talcum powder, 5-10% of sepiolite, 2-5% of pigments, 2-4% of pregelatinized starch, 1-3% of hydroxypropyl methyl cellulose, 1-2% of dispersible latex, 1-2% of starch ether, 0.5-2% of sodium tripolyphosphate, 0.5-2% of sodium hexametaphosphate, 0.5-1% of polyvinyl alcohol, 0.1-0.5% of guar gum and 0.1-3% of nanometer titania. The preparation method is simple and easy to construct, and the diatom ooze is porous matter, can adsorb and decompose hazardous substances such as methanal and methylbenzene and has the functions of regulating humidity and removing peculiar smell.
