Embodiment 1

[0024]Example 1: First select 0.35um water filter membrane, 283 parts of water, 2 parts of defoamer, 6 parts of salt dispersant, 2 parts of non-ionic wetting agent, 130 parts of heavy calcium, 260 parts of diatomaceous earth, 6 parts of nano-titanium dioxide , 140 parts of pure elastic emulsion, 3 parts of polyurethane thickener, add the above-mentioned materials in accurate proportions and put them in a horizontal high-speed disperser for uniform dispersion to obtain the desired antibacterial and aldehyde-free diatom mud wall paint.

[0025]The specific operation step of the first embodiment: firstly, the tap water is filtered with a 0.35um water-based filter membrane;

[0026]Step 2: Add 280 parts of water, 1 part of antifoaming agent and 2 parts of multifunctional additives in sequence, and mix them evenly;

[0027]Step 3: Next, add 6 parts of salt dispersant and 2 parts of non-ionic wetting agent to mix and stir evenly;

[0028]Step 4: Add 130 parts of heavy calcium, 260 parts of diatomaceo...

Embodiment 2

[0035]The difference between Example 2 and Example 1 is that 8 parts of polyurethane thickener are added.

[0036]Polyurethane thickener is added in a large amount, resulting in a higher viscosity of the antibacterial and aldehyde-free diatom mud wall coating after molding, and the antibacterial and aldehyde-free diatom mud wall coating is not easy to be applied to the wall.

Embodiment 3

[0038]The difference between Example 3 and Example 1 is that 1 part of polyurethane thickener is added.

[0039]The addition of polyurethane thickener is too small, resulting in lower viscosity of the antibacterial and aldehyde-free diatom mud wall coating, which results in a thinner antibacterial and aldehyde-free diatom mud wall coating. Delamination, agglomeration, etc. will occur, splashing and sagging will occur during construction.

Abstract

The invention discloses an antibacterial formaldehyde-free diatom ooze wall coating and a preparation method thereof. The antibacterial formaldehyde-free diatom ooze wall coating comprises the following components: diatomite, a modifier, an odorless elastic emulsion, a nonionic wetting agent, an antifoaming agent, water, nano titanium dioxide, ground calcium carbonate, a dispersion medium, an inert filler, a thickener, a multifunctional assistant and other assistants. According to the antibacterial formaldehyde-free diatom ooze wall coating and the preparation method thereof, the antibacterialformaldehyde-free diatom ooze wall coating has the advantages of being free of VOC, capable of adsorbing formaldehyde, methylbenzene and other organic matter and the like, stable in performance and long in effective service life; and the problems that an existing antibacterial formaldehyde-free diatom ooze wall coating and a preparation method thereof have VOC emission, cannot adsorb formaldehyde, methylbenzene and other organic matter and are poor in antibacterial effect are solved.

Description

Technical field[0001]The invention belongs to the technical field of antibacterial and aldehyde-free diatom mud wall coatings, and particularly relates to an antibacterial and aldehyde-free diatom mud wall coatings and a preparation method thereof.Background technique[0002]Diatom mud is an environmentally friendly decorative wall material for interior walls using diatomaceous earth as the main raw material. Diatomaceous earth is a siliceous rock formed from the remains of silicate after the death of single-celled algae collectively called diatoms. The main component is silicon dioxide, which is shown as a micron-sized porous material under an electron microscope. The porosity is 90%. The number of micropores per unit area is thousands of times more than that of charcoal. This kind of performance makes the diatom mud have good functions of adsorbing formaldehyde, purifying the air, adjusting humidity, releasing negative oxygen ions, fire retardant, self-cleaning walls, sterilization ...
