Problems solved by technology

[0005] However, methyl acetate and isopropanol are used as organic solvents in the preparation process of the diatom mud latex paint, but the preparation process of the diatom mud, especially the amount of isopropanol used is relatively large, and the diatom mud is coated indoors. Behind the wall, isopropyl alcohol and methyl acetate will volatilize into the air, which is not conducive to the quality of indoor air

Abstract

The invention discloses water-based diatom ooze and a preparation method thereof. The water-based diatom ooze is prepared from the following ingredients in parts by mass: 270 to 320 parts of kieselguhr, 5 to 8 parts of sodium salt dispersant, 145 to 185 parts of coarse whiting, 3 to 7 parts of propylene glycol, 160 to 185 parts of odor removing elastic emulsion, 2 to 4 parts of nonionic wetting agent, 2 to 5 parts of defoaming agent, 50 to 80 parts of nanometer titania, 1 to 3 parts of cellulose, 5 to 10 parts of thickening agent, 2 to 3 parts of multifunctional additive, 310 to 360 parts of water and A to B parts of other additives. The preparation method comprises the steps of adding the raw materials time after time, evenly stirring and then adding the following-up raw materials. In a preparation process, the water-based diatom ooze needs to be sanded, so that solution can meet a certain fineness requirement. According to the water-based diatom ooze preparation method, only water is added into the water-based diatom ooze to serve as the dispersant, all the raw materials can be fully mixed, and even water-based diatom ooze can be prepared and obtained.

Description

technical field [0001] The invention relates to the field of diatom ooze, more specifically, it relates to a water-based diatom ooze and a preparation method thereof. Background technique [0002] The main 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. The main component of diatom ooze is opal, and the electron microscope shows that there are countless tiny holes on the surface of the particles, the porosity is over 90%, the specific surface area is as high as 65㎡ / g, and it has a relatively prominent molecular sieve structure, which makes it extremely strong. Physical adsorption performance, can absorb a large amount of water and formaldehyde, the surface of diatom mud is rough and porous, has good sound insulation effect, and diatom mud wall material is resistant to high temperature. [0003] The construction of water-based diatom mud is simple, no ne...
