Problems solved by technology

[0003] At present, most diatom mud manufacturers in the market obtain diatom mud product powder through one-time feeding, but the powder and water of the diatom mud product powder are difficult to fully integrate during the on-site mixing process, although the powder and water seem to be stirred on the surface The mixture is uniform, but in fact, the hydration and fusion of the material has not been fully achieved, resulting in material color spots, pigment color spots, etc. on the surface of the diatom mud product on the wall, which seriously affects the decorative effect of the diatom mud product. Seriously, due to insufficient hydration and fusion of diatom ooze powder, the water retention performance of diatom ooze products is unstable, and the construction window period is difficult to control. Powder, discoloration and other problems
In order to avoid the above problems, at present, the constructors only rely on stirring the diatom ooze repeatedly, repeatedly, and for a long time when using it, resulting in large energy consumption, low construction efficiency, and high labor costs.

preparation example Construction

[0069] In the preparation of the premix in the present invention, there is no special limitation on the equipment used for mixing and stirring, and the equipment known to those skilled in the art that can realize the mixing and stirring of diatom ooze powder is sufficient. The present invention preferably adopts the JZ-02Q high-speed cutting and stirring dispersing machine for mixing and stirring.

[0070] After obtaining the premix, mix and stir the premix, kaolin, calcium hydroxide and titanium dioxide, then add diatomaceous earth, sepiolite powder, sepiolite wool and heavy calcium carbonate, mix and stir, and finally add white silica sand Mix and stir to obtain coarse diatom mud powder.

[0071] In the present invention, there is no special limitation on the instruments used in the preparation and mixing of the coarse diatom ooze powder, and the instruments known to those skilled in the art can realize the mixing and stirring of the diatom ooze powder. In the present inven...

Embodiment 1

[0138] Embodiment 1 prepares the premix of coarse material diatom ooze powder

[0139] The model is JZ-02Q high-speed cutting and stirring dispersing machine for the preparation of premix

[0140]First put 25wt% of 800 mesh talc powder into the high-speed cutting and stirring disperser, then add 8.4wt% of polyvinyl acetate redispersible latex powder, 16.7wt% of attapulgite, 3.3wt% of methyl hydroxypropyl Base cellulose ether, 5wt% wood fiber, 1.7wt% seaweed powder, 6.6wt% sulfonated naphthalene wetting and dispersing agent and 8.3wt% nano-titanium dioxide diatomite composite photocatalytic material at 1000 rpm After mixing and stirring for 2 minutes, 25 wt% of 800-mesh talcum powder was added and mixed and stirred for 7 minutes under the condition of 1000 rpm to obtain a premix. The premix quality inspection, metering and filling equipment are used.

Embodiment 2

[0142] The model is JZ-02Q high-speed cutting and stirring dispersing machine for the preparation of premix

[0143] First, 19wt% of 800-mesh talcum powder was put into the high-speed cutting and stirring disperser, followed by adding 12wt% of polyvinyl acetate redispersible latex powder, 16.7wt% of attapulgite, and 4.8wt% of methyl hydroxypropyl Cellulose ether, 6.4wt% wood fiber, 3.2wt% seaweed powder, 7.9wt% sulfonated naphthalene wetting and dispersing agent and 11wt% nano-titanium dioxide diatomite composite photocatalytic material under the condition of 1300 rpm After mixing and stirring for 2 minutes, 19 wt% of 800-mesh talcum powder was added and mixed and stirred for 7 minutes under the condition of 1300 rpm to obtain a premix. The premix quality inspection, metering and filling equipment are used.

Abstract

The invention provides coarse diatom ooze powder and a production process thereof. The production process is simple, the water solubility of the diatom ooze powder is improved through specific mixing procedures, the fusion rate between the diatom ooze powder and water is improved, the construction window phase is prolonged, and the effect of long-time use can be achieved through one-time stirring. By means of the coarse diatom ooze powder and the production process thereof, the problem of surface decoration effect of a wall which is constructed and coated with a diatom ooze product on current market can be solved, and the construction efficiency of the diatom ooze product can be improved as well, in the using process, the stirring time is short, the energy consumption is saved, and the total cost of the diatom ooze product is reduced.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a coarse diatom mud powder and a production process thereof. Background technique [0002] Diatom mud products are mainly dry powder coating materials composed of diatomite and a variety of inorganic non-metallic mineral powder materials with gelling materials and appropriate additives. According to a certain proportion of water and powder in the mixing tank, it is stirred into a mud paste or mud shape, and is applied to the wall by scraping, wiping, spraying and other methods. [0003] At present, most diatom mud manufacturers in the market obtain diatom mud product powder through one-time feeding, but the powder and water of the diatom mud product powder are difficult to fully integrate during the on-site mixing process, although the powder and water seem to be stirred on the surface The mixture is uniform, but in fact, the hydration and fusion of the material has...
