[0015] Part 1: First, add a certain amount of water into the dispersion tank. At a speed of about 600r / min, add cellulose, defoaming agent, wetting and dispersing agent, multifunctional additive, ethylene glycol, etc. in order according to the formula amount. After adding, continue to disperse for about 10 minutes until uniform;

[0022] S2, color adjustment and granulation stage

[0023] S2.1 The colorist mixes the base paint according to the sample and color dot ratio and mixes the color. After the color is mixed but before granulation, a small test spray board is carried out to confirm that the size and hue of the color dot are qualified.

[0025] S3, finished product production stage

[0026] Add the granulated mixed color dots into the continuous phase and mix evenly. Then make a small test spray plate for the second time to determine whether the color dot size and hue are qualified. After the spray plate is confirmed to be qualified, add thickener to the system to adjust the viscosity. After the viscosity is qualified, send it for inspection. After the hue, viscosity, pH value and other indicators are qualified, notify the production, packaging and shipment.

[0031] An application of an inorganic multi-color coating comprises the following steps:

[0032] a. Grassroots processing

[0033] Before construction, use a spatula to fill the base with mortar to ensure that the base is flat, solid and clean. Test the alkalinity of the wall to control the wall pH to <10. Otherwise, use oxalic acid to clean it. Test the dryness of the base to ensure that the moisture content is <10%. Otherwise, it needs to be cured until it meets the requirements.

[0034] b. Putty

[0035] Use exterior wall putty to level the base layer to provide a solid and flat base surface for Zhencai Stone Paint. Apply 2-3 coats of putty according to the characteristics of the base layer. After 7 days of curing, ensure that the putty layer is strong enough, with a pH value of <10 and a moisture content of <10%. Only after passing the standards can the primer be applied.

[0036] c. Apply colorful special penetrating primer

[0037] After the putty is completely dry, apply a layer of Hubao colorful stone penetrating primer. Generally, it is applied by roller coating, but it can also be sprayed. The construction temperature should be above 5℃. The speed should be kept consistent during construction so that the primer can be evenly and continuously applied to avoid missing paint.

[0038] d. Pointing

[0039] According to the lines, horizontal and vertical points designed by the client, draw the lines, mark the joint paint, and then apply protective tape on the joint paint to prepare for the next process;

[0040] e. Roller-coat the main color paint

[0041] When applying flat color main paint, no water is needed. When the temperature is above 5℃, apply corresponding colored main color paint according to the sample requirements to provide a good background color effect for Zhencai Stone Paint. After 1-2 days of maintenance after construction, apply Zhencai Stone Paint.

[0042] f. Apply colorful special topcoat

[0043] After the paint is completely dry, apply the colorful special super weather-resistant topcoat. The temperature during construction must not be lower than 5°C. Generally, no water is added to keep the viscosity of the topcoat consistent and the construction speed uniform so that the topcoat is even and continuous to avoid missing paint.

[0044] A basic paint raw material mixing device comprises a body and a cover, wherein a mixing mechanism is provided inside the body, and a filtering mechanism is provided inside the body;

[0046] The rotating shaft is fixedly mounted with auger blades, the rotating shaft passes through the interior of the conveying cylinder, the motor is fixedly mounted on the upper surface of the machine cover, the upper surface of the machine cover is provided with a feed port, and the bottom of the machine body is provided with a discharge port. By starting the motor to drive the rotating shaft to rotate, the rotating shaft drives the auger blades to convey the raw materials at the bottom of the machine body upward, so that the raw materials can be circulated and stirred up and down, thereby improving the efficiency of mixing and stirring the raw materials;

[0047] Preferably, the outer wall of the body is fixedly mounted with support legs, the number of the support legs is three, and the three support legs are fixedly mounted at the bottom of the body at equal intervals. The arrangement of the support legs can support and fix the body, making the body more stable when in use;

[0048] Preferably, the filtering mechanism includes a fixed outer ring and a fixed inner ring, the fixed inner ring is fixedly mounted on the outer wall of the conveying cylinder, and the fixed outer ring is fixedly mounted on the inner wall of the body. The setting of the filtering mechanism can filter and intercept the mixed liquid raw materials, so that the raw materials that are not completely dissolved are intercepted on the upper surface of the metal filter mesh, and then ground with the metal filter mesh under the action of the scraper so that they are dissolved into the liquid, thereby further improving the efficiency of mixing the base paint raw materials;

[0049] Preferably, a metal filter is fixedly mounted on the outer wall of the fixed inner ring, and the metal filter is fixedly mounted on the inner wall of the fixed outer ring, so that the fixed inner ring and the fixed outer ring can fix the metal filter;

[0050] Preferably, a scraper is fixedly mounted on the lower end of the first stirring rod, and the lower end of the scraper is in contact with the upper surface of the metal filter.

[0051] Compared with the prior art, the present invention has the following beneficial effects:

[0052] 1. By adding a luminescent material of a mixture of CaAl2O4 calcium aluminate and BaAlO4 barium aluminate, the luminescent material can absorb and store solar energy in some way when exposed to sunlight during the day. At night, the energy stored inside is converted into light radiation and released to achieve a luminous effect, realizing the luminous function of the paint.

[0053] 2. Inorganic modified emulsion is used as the film-forming material. The traditional organic emulsion is made inorganic through special synthesis technology to meet the inorganicization of the film-forming material. Inorganic additives are used instead of organic additives, and inorganic silicate suspending agents are used instead of organic thickeners to achieve inorganic fireproofing function.

[0054] 3. By adding sufficient film-forming substances with excellent weather resistance and chemical resistance, combined with inorganic protective glue and other high-end additives, after experimental tests and application tests, they all meet the comprehensive performance standards of ordinary water-based multi-color.

[0055] 4. By starting the motor to drive the shaft to rotate, the shaft drives the auger blades to transport the raw materials at the bottom of the body upward, so that the raw materials can be circulated and stirred up and down. At the same time, when the raw materials under the conveying cylinder are transported upward, the raw materials on the periphery of the conveying cylinder will sink, so that the raw materials will pass through the metal filter and be filtered by the metal filter. The undissolved block raw materials are intercepted on the upper surface of the metal filter, and then ground with the metal filter under the action of the scraper, so that they are dissolved into the liquid, thereby improving the efficiency of mixing the base paint raw materials.

The motor 201 is fixedly mounted on the upper surface of the machine cover 4. The upper surface of the machine cover 4 is provided with a feed port 5, and the bottom of the machine body 1 is provided with a discharge port 7. By starting the motor 201 to drive the rotating shaft 202 to rotate, the rotating shaft 202 drives the auger blade 204 to convey the raw materials at the bottom of the machine body 1 upward, so that the raw materials can be circulated and stirred up and down, thereby improving the efficiency of raw material mixing;

[0162] The outer wall of the body 1 is fixedly mounted with support legs 6. There are three support legs 6, which are fixedly mounted at equal intervals on the bottom of the body 1. The arrangement of the support legs 6 can support and fix the body 1, making the body 1 more stable when in use.

[0163] As shown in Figures 4-6, the filtering mechanism 3 includes a fixed outer ring 301 and a fixed inner ring 304. The fixed inner ring 304 is fixedly mounted on the outer wall of the conveying cylinder 203, and the fixed outer ring 301 is fixedly mounted on the inner wall of the body 1. The setting of the filtering mechanism 3 can filter and intercept the mixed liquid raw materials, so that the undissolved raw materials are intercepted on the upper surface of the metal filter 302. Then, under the action of the scraper 303, the metal filter 302 grinds the raw materials so that they are dissolved in the liquid, further improving the efficiency of mixing the base paint raw materials.

[0167] Specifically, by arranging the filter mesh cylinder 8 inside the feed port 5, the paint can be filtered, thereby preventing impurities in the paint from affecting the quality of the paint and improving the practicality of the raw material mixing device.

[0168] By starting the motor 201 to drive the rotating shaft 202 to rotate, the rotating shaft 202 drives the auger blades 204 to transport the raw materials at the bottom of the body 1 upward, so that the raw materials can be circulated and stirred up and down. At the same time, after the raw materials below the conveying cylinder 203 are transported upward, the raw materials on the periphery of the conveying cylinder 203 will sink, so that the raw materials will pass through the metal filter 302 and be filtered by the metal filter 302. The undissolved block raw materials are intercepted on the upper surface of the metal filter 302, and then ground by the metal filter 302 under the action of the scraper 303, so that they are dissolved into the liquid, thereby improving the efficiency of mixing the base paint raw materials.
