Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of building composite materials, and in particular relates to an environment-friendly diatom mud composite material and a preparation method thereof. Background technique [0002] The main raw material of diatom mud is diatom earth, a diatom mineral that has been formed for hundreds of millions of years. Diatom is a kind of algae that lives in oceans and lakes. Oceans and lakes are the hometown of algae. There are many types and large numbers of diatoms here. They are called grasslands in the ocean. They create 70% of the oxygen on which life on earth depends, and are the cradle of life on earth. Diatom mud is taken from aquatic plankton living millions of years ago—a natural substance deposited by diatoms. The main component is opal, which is rich in a variety of beneficial minerals and has a light and soft texture. The electron microscope shows that its particles There are countless tiny pores on the surf...
