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...

preparation example Construction

[0073] 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 enough. The present invention preferably adopts the JZ-02Q high-speed cutting and stirring dispersing machine for mixing and stirring.

[0074] After obtaining the premix, the present invention mixes and stirs the premix, kaolin and white carbon black, then adds diatomite, sepiolite powder, anatase titanium dioxide, light calcium carbonate, white cement and bentonite and mixes and stirs , and finally add calcium hydroxide, heavy calcium carbonate and white silica sand and mix and stir to obtain fine diatom mud powder. In the present invention, there is no special limitation on the equipment used in the preparation and mixing of the fine diatom mud powder, and any instrument known to those skilled in the art that can rea...

Embodiment 1

[0146] Embodiment 1 prepares the premix of fine material diatom ooze powder

[0147] The model is JZ-02Q high-speed cutting and stirring dispersing machine for the preparation of premix

[0148]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

[0150] The model is JZ-02Q high-speed cutting and stirring dispersing machine for the preparation of premix

[0151] 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 a production technology of fine diatom ooze powder. The technology is simple. The water solubility of the diatom ooze powder is improved through specific mixing steps, the fusion rate of the diatom ooze powder and water is increased, the construction window phase is prolonged, and the long-term using effect can be achieved through one-time stirring. The surface decorative effect problem caused when diatom ooze products in the current market are constructed and coated on a wall can be solved, and the construction and coating efficiency of the diatom ooze products can be improved. The stirring time is short in the using process, energy consumption is reduced, and the overall cost of the diatom ooze products is lowered.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a fine 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 n...
