[0093] The preparation of the coating composition of the present invention and the testing of its various properties are described in detail below by way of examples. It should be understood that these examples are only for the purpose of understanding the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0094] Example 1: Preparation and performance testing of coating composition samples

[0095] 1. Preparation of coating composition samples

[0096] Mortar Sample Preparation

[0097] The mortar used to prepare each sample was prepared with the following composition (see Table 3 below): In the mortar of the sample, cement:(Ulancha crystal component + sand) = 1:6. In the mortar preparation experiment, 1 part cement = 1580 grams. The amount of titanium dioxide added was a percentage of the total solid weight, i.e. titanium dioxide / (cement + Ulancha crystal component + sand) × 100%. The amount of water added was in grams.

[0098] The mortar preparation method for the samples is as follows: First, weigh all the solid raw materials according to the proportions and mix them evenly in a container. Add water while mixing, control the amount of water added, and adjust to form a uniform mortar. Pour the mortar into three 70.7×70.7 mm (for negative oxygen ion measurement) and twelve 50.0×50.0 mm (for antibacterial experiment) concrete plastic molds with side lengths of 50.0×50.0 mm respectively. After air drying for 48 hours, remove the samples from the molds and place them in an oven at 200℃±5℃ for one hour to complete the sample preparation.

[0099] Let's take sample 1 as an example for a detailed explanation:

[0100] Weigh out 3160g of Wulancha Crystal Component 1 (i.e., Wulancha Crystal B material, from Inner Mongolia Huachen Renewable Resources Technology Co., Ltd.), 3160kg of Wulancha Crystal Component 2 (i.e., Wulancha Crystal C material, from Inner Mongolia Huachen Renewable Resources Technology Co., Ltd.), 221g of titanium dioxide (using rutile titanium dioxide produced by Tianjin Maister Technology Co., Ltd.), 1580g of cement (using 42.5 Yufeng ordinary Portland cement produced by Guangxi Yufeng Cement Group Co., Ltd.), and 3160g of sand (using sand made from local pebbles crushed in Duyun City, Qiannan Prefecture, Guizhou Province, sieved, with a maximum size not exceeding 5mm).

[0101] The conventional composition and loss on ignition of the Ulancha crystal B and Ulancha crystal C materials were determined according to GB / T4734-1996, and the specific test results are shown in Table 1 below:

[0102] Table 1: Results of determination of conventional composition and loss on ignition of Wulancha Crystal B and Wulancha Crystal C materials

[0103]

[0104]

[0105] The rare earth element composition of the Ulancha Crystal B and Ulancha Crystal C materials used above was determined according to GB / T14506.30-2010, and the specific test results are shown in Table 2 below:

[0106] Table 2: Determination results of rare earth element composition of Wulancha Crystal B and Wulancha Crystal C materials

[0107]

[0108] Place the weighed raw materials into a container and mix them evenly. Then, add water while continuing to mix, controlling the amount of water added, to form a uniform mortar. Pour the mortar into a concrete plastic mold with a side length of 70.7 mm and let it air dry naturally for 48 hours. Then, remove the sample from the mold and place it in an oven at 200℃±5℃ for one hour to complete the preparation of sample 1.

[0109] Referring to the data in Table 3, prepare mortar for other samples (samples 2-13) and complete the preparation of other samples. Among them, in addition to adding the same components as those in samples 1-11, 0.32g and 0.47g of alkali-resistant agent (ultra-micro alkali-resistant internal admixture produced by Tianjin Maister Technology Co., Ltd.) were added to samples 12 and 13 respectively, at a dosage of 0.02% and 0.03% of the cement weight. Samples 2-13 were prepared using the same steps as sample 1.

[0110] 2. Performance testing of coating composition samples

[0111] Negative oxygen ion detection was performed on each prepared and dried sample.

[0112] The negative oxygen ion detection equipment is the IMH01 negative ion detector manufactured by Beijing Dongchuang Xuxin Measurement and Control Technology Co., Ltd.

[0113] Negative oxygen ion detection procedure:

[0114] Step 1: Place the IMH01 negative ion detector and sample holder into the self-made measuring box, which is a square wooden box with internal dimensions of length × width × height = 300 × 300 × 300 mm, with a glass door on the front. During the measurement process, keep the distance between the detector and each sample the same.

[0115] The second step is to place the sample on the sample holder, ensuring that the left side and front of the sample are close to the chamber wall, then turn on the detector, select the intermittent measurement mode, and then close the glass door.

[0116] Third, 5 minutes after the detector is turned on, start the average value measurement, close the glass door in time, and record the 10th average measurement value;

[0117] Fourth step: After recording the measurement values, turn off the machine, remove the sample, and complete the sample test.

[0118] If steps one through four above are completed to determine the negative oxygen ion concentration of sample 1, the result is 692 negative oxygen ions / cm³. 3 See Table 3 below.

[0119] Accordingly, repeat steps one through four above to complete the negative oxygen ion determination of other samples (samples 2-13). See Table 3 below for specific results.

[0120] In addition to preparing mortar for samples 1-13, making samples, and measuring negative oxygen ions, the inventors also made control samples and measured negative oxygen ions.

[0121] Control 1 involved mixing 1 part cement (1580g), 6 parts sand (9480g), and 221g titanium dioxide (2% of the total weight of the two) with 1600g of water to form a mortar. This mortar was then shaped, dried, and used to prepare a sample. Steps one through four were then repeated to measure the negative oxygen ions, resulting in 179 negative oxygen ions / cm³. 3 ;

[0122] Compared to control 2, the negative oxygen ion concentration in the unfinished room, measured using the same negative ion detector, was 230 negative oxygen ions / cm³. 3 ;

[0123] For control 3, a plastic sample of the same size, the measured negative ion concentration was 18 negative oxygen ions / cm³. 3 ;

[0124] Reference 4, a type of black crystal B, has a measured negative ion concentration of 3500 negative oxygen ions / cm³. 3 For details, please refer to Table 1 below.

[0125] As can be seen from the sample composition, experimental process, and experimental data in Table 3 below:

[0126] (1) Ordinary mortar without B and C components has the lowest water consumption;

[0127] (2) Mortar containing Ulancha crystal B material is easier to form than normal mortar;

[0128] (3) The mortar containing Ulancha crystal C material has the highest water consumption and is not easy to form;

[0129] (4) The higher the rare earth element content of the mortar components, the greater the negative oxygen ion value.

[0130] (5) As a mortar whitening agent, the whitening effect of titanium dioxide is directly proportional to the amount added, and has little effect on the composition of mortar.

[0131] (6) When an anti-alkali agent is added to the mortar, the negative oxygen ion value measured by the mortar sample made from its components is basically the same as that measured by the mortar sample made from the same component dosage but without the anti-alkali agent. Therefore, it can be seen that adding an appropriate amount of anti-alkali agent to the mortar has basically no effect on the release of negative oxygen ions on the coating surface.

[0132]

[0133] Example 2: Coating and Performance Testing in the Experience Center

[0134] 1. Preparation of coating mortar used in various areas

[0135] The mortar used for painting each room and area of ​​the experience center is prepared as follows (see Table 4 below):

[0136] Weigh each component according to the weights listed in Table 4 below to prepare the coating mortar for each room and area, where:

[0137] Both Wulancha Crystal B material (i.e., Wulancha Crystal Component One) and Wulancha Crystal C material (i.e., Wulancha Crystal Component Two) come from Inner Mongolia Huachen Renewable Resources Technology Co., Ltd.

[0138] The titanium dioxide used is rutile titanium dioxide produced by Tianjin Master Technology Co., Ltd.

[0139] The white cement used is P·W42.5 cement produced by Guangxi Guigang Yunpeng Special Cement Co., Ltd.

[0140] The gray cement used is M32.5 cement produced by Guizhou Duyun Shangfeng Southwest Cement Co., Ltd.

[0141] The river sand is made from crushed pebbles from Duyun City, Qiannan Prefecture, Guizhou Province, and sieved so that the maximum size does not exceed 5mm.

[0142] The anti-alkali agent is an ultra-micro anti-alkali additive purchased from Morester.

[0143] Weigh the above raw materials according to the mortar mix ratio for each area of ​​the experience center, and pour them into a small concrete mixer. Gradually add tap water as needed, turn on the machine to mix evenly, and obtain mortar suitable for painting the walls and floors of the rooms and areas. Paint and smooth the walls and floors of each room and area, and then let them dry naturally for several days.

[0144] Table 4: Mortar Formulas for Different Areas of the Experience Center

[0145]

[0146] Note: Wulancha crystal B material, from Inner Mongolia Huachen Renewable Resources Technology Co., Ltd., with a particle size of 200-1500 mesh;

[0147] Ulancha crystal material C, sourced from Inner Mongolia Huachen Renewable Resources Technology Co., Ltd., with a particle size of 50-180 mesh;

[0148] White cement: Model P·W42.5, Manufacturer: Guangxi Guigang Yunpeng Special Cement Co., Ltd.;

[0149] Grey cement: Model M32.5, Manufacturer: Guizhou Duyun Shangfeng Southwest Cement Co., Ltd.

[0150] Alkali resist agent: Ultra-micro alkali resist additive purchased from Morester is used, at a concentration of 20g / m³. 2The dosage is prepared into a 5wt% aqueous solution. After the mortar is applied to the walls and floors, and the surface is allowed to dry naturally to a semi-dry state, the walls and floors of the warehouse are then sprayed with an ultra-micro amount of anti-alkali additive aqueous solution.

[0151] 2. Negative oxygen ion performance testing in various areas of the experience center

[0152] After the painted walls and floors of each room and area of ​​the experience center were completely dry, the number of negative oxygen ions in each room was continuously measured on different dates using an IMH01 negative ion detector. The neighbor's master bedroom was used as control 1, and the outdoor data was used as control 2. The specific results are shown in Table 5 below.

[0153] Table 5: Negative Oxygen Ion Measurement Data in the Experience Center (Unit: ions / cm³) 3 )

[0154]

[0155] Note: The neighbor's master bedroom was used as control 1, and the outdoor data was used as control 2 (the outdoor sampling point of the experience center where negative oxygen ions were measured was near a large number of green plants, which is an area with good air conditions). The number of negative oxygen ions was measured on the same date using the IMH01 negative ion detector.

[0156] The areas that were not measured before November 9, 2023, were not measured because they had not yet been painted or had not yet dried after painting.

[0157] Based on the test results in Table 5, it can be seen that:

[0158] 1) The walls and floors of various areas of the experience hall are coated with the coating composition of the present invention to make coating mortar material for room decoration. The negative oxygen ion concentration in various areas of the experience hall is greater than that in control 1 (i.e., the master bedroom of the neighbor's house). The negative oxygen ion concentration in various areas of the experience hall is also greater than that in control 2 (i.e., the outdoor measurement data). Therefore, the coating material can be used as a negative oxygen ion generator after drying.

[0159] 2) The negative oxygen ion levels vary considerably in different areas of the experience center, and are affected by, but are not limited to, the following factors: room cleanliness, human activity, weather, air humidity, etc.

[0160] 3) The maximum value of negative oxygen ions in each area of ​​the experience center is the most effective data, and this value represents the efficacy and effect of the negative oxygen ion source in that area;

[0161] 4) To prevent efflorescence on walls or floors due to cement moisture absorption or a humid environment after a period of use, after the mortar is applied to the walls and floors, spray an anti-alkali agent aqueous solution onto the warehouse walls and floors when they are naturally dried to a semi-dry state. After they are completely dry, measure the negative oxygen ions. The test results show that spraying an ultra-micro amount of anti-alkali additive aqueous solution onto the warehouse walls and floors has little effect on the release of negative oxygen ions. Therefore, when using the coating composition of the present invention, an anti-alkali agent can be used in an appropriate amount to avoid efflorescence.

[0162] Example 3: Testing of the far-infrared emission performance of the coating composition

[0163] The inventors also tested the far-infrared emission performance of the coating composition of the present invention.

[0164] The far-infrared emission wavelengths of samples 1 and 7 of the coating composition of the present invention in Example 1 were measured using an infrared radiometer. Simultaneously, samples 1 and 7 of the coating composition of the present invention were prepared as specimens with a size of 100mm × 100mm; the far-infrared emission intensity of the coating composition samples of the present invention in different wavelength ranges was measured according to the standard LY / T 3203-2020 "Method for Determination of Far-Infrared Emissivity of Bamboo Charcoal".

[0165] The far-infrared emission performance test results of the coating composition samples 1 and 7 of the present invention are shown in Table 6 below.

[0166] Table 6: Test results of far-infrared emission performance of coating compositions of the present invention, samples 1 and 7

[0167] Test item Composition sample 1 Composition sample 7 Emission wavelength (μm) 6-20 6-20 Emission intensity 8 μm-14 μm wavelength: 0.916 8 μm-14 μm wavelength: 0.879

[0168] As can be seen from the test results in Table 6 above, the coating composition of the present invention also has excellent far-infrared emission performance with health care function.

[0169] Example 4: Antibacterial performance test of the sample

[0170] The mortar of Sample 1 and Sample 7 of the coating composition prepared in Example 1 above was used to make ceramic tile samples for antibacterial performance testing. Twelve samples were prepared, each measuring 50mm × 50mm. The tests were conducted according to JC / T 897-2014 "Antibacterial Properties of Antibacterial Ceramic Products," targeting Staphylococcus aureus AS1.89 and Escherichia coli AS1.90. The test results are shown in Table 7 below.

[0171] Table 7: Test results of antibacterial properties of the coating composition of the present invention, samples 1 and 7

[0172]

[0173] As can be seen from the results in Table 7 above, the coating composition of the present invention has excellent antibacterial properties.

[0174] The inventors explored the antibacterial properties, far-infrared emission, and negative ion generation mechanism of Ulancha crystal in the preparation of coating compositions and building components.

[0175] Currently available inorganic antibacterial agents are basically divided into two categories: one is metal ions, such as Ag, which are active components. + Zn 2+ Cu 2+ Another type is oxide photocatalysis, such as TiO2, ZnO, MgO, etc., whose mechanisms of action are roughly as follows: The first type is the metal ion-type contact reaction: metal ions are firmly adsorbed onto the cell membrane by electrostatic forces, then break through the cell wall to enter the cell, causing bacterial proteins to coagulate, and the cell will lose its ability to divide and proliferate and die. Simultaneously, metal ions can also disrupt the microbial electron transport system, respiratory system, and material transport system. The second type is the metal ion-type photocatalytic reaction: under the action of light, metal ions are excited and undergo electron transfer, producing -OH and O2 from water and O2 in the air adsorbed on the glaze surface. - They can disrupt the bacteria's ability to multiply in a short period of time, inhibiting or killing the bacteria.

[0176] The first type of antibacterial agent generally requires an active carrier to load the metal ions, such as zeolite, activated carbon, silica gel, and phosphates, which can serve as metal ion carriers. The second type, oxide photocatalytic antibacterial agents, mainly undergo redox reactions under light irradiation. For example, TiO2-type antibacterial agents, under ultraviolet light irradiation, react with Ti... 3+ With Ti 4+ Electron transfer occurs, generating a large number of highly reactive negative oxygen ions and free radicals (OH groups) on the surface. When these free radicals come into contact with microorganisms, they can oxidize them into CO2 and H2O, thus achieving sterilization in a short time. Both types of antibacterial agents, except for the contact reaction in the first category, require the aid of light. The second type, photocatalytic oxides, in particular, generally require high-energy light such as ultraviolet or near-ultraviolet light, thus limiting their application.

[0177] In order to expand the photoresponse range of the above-mentioned antibacterial agents and enable them to continue to exert their antibacterial effects under visible light or no light conditions, scientists have conducted a lot of research in recent years. By using rare earth activation and composite technology, new energy levels are added to the surface of metal oxide photocatalytic materials, realizing multi-band photocatalytic reactions under visible light and ultraviolet light conditions, improving the generation capacity of radical free radicals, and enhancing the function of materials through photocatalysis and rare earth variable valence synergy.

[0178] The various products developed by this invention do not require the addition of any antibacterial agents. The coating compositions or components of this invention, such as building components and vehicle / ship interior parts, use raw materials containing Ulancha crystal B or C material. Ulancha crystal contains a rich variety of rare earth elements as well as conventional elements, such as magnesium oxide, calcium oxide, titanium oxide, iron oxide, etc. Due to the presence of rare earth elements, the products have the function of emitting far-infrared rays and generating negative oxygen ions, and can also produce the same effect as a second type of antibacterial agent.

[0179] The above is merely a preliminary exploration by the inventors of the antibacterial properties, far-infrared emission, and negative ion generation mechanism of the coating composition and building components prepared by this invention. It should be understood that it does not constitute a limitation on the scope of protection of this invention.

[0180] Example 5: Radioactivity Detection of Ulan Tea Crystal

[0181] Since the coating composition and the components made therefrom of the present invention use components processed from natural raw material Ulancha crystal stone, specifically Ulancha crystal stone B and C materials, in order to ensure that the coating composition and the components made therefrom do not have any negative radioactive effects on the human body, the inventors tested the radioactivity of the Ulancha crystal stone raw ore.

[0182] The testing was conducted according to the standard GB 6566-2010 "Limits of Radionuclides in Building Materials". A Mini-1024 low-background multichannel gamma-ray spectrometer was used to test the raw ore of Wulancha crystal. The specific test items and results for the raw ore of Wulancha crystal are shown in Table 8 below.

[0183] Table 8: Detection Results of Radionuclides in Raw Wulan Tea Crystal Ore

[0184]

[0185] As can be seen from the results in Table 8 above, the radionuclide detection results of the raw materials for preparing the coating combination and components of the present invention, namely, Ulancha crystal B material and / or Ulancha crystal C material, fully comply with the testing standards of GB6566-2010 "Limits of Radionuclides in Building Materials". Therefore, it is completely safe in terms of reflectivity for coatings used in residential decoration or interior decoration in various other occasions.

[0186] Example 6: Detection of heavy metal content in Wulan tea crystals

[0187] Since the coating composition and the components made therefrom of the present invention use components processed from natural raw material Ulancha crystal ore, namely Ulancha crystal B material and Ulancha crystal C material, in order to ensure that the coating composition and the components made therefrom do not have any negative radioactive effects on the human body, the inventors tested the content of heavy metals (including arsenic) in the natural raw material Ulancha crystal ore.

[0188] The heavy metal content of the raw Wulancha crystal ore was detected using the ICP-OES method, and the contents of heavy metals such as lead, mercury, cadmium, chromium and arsenic were determined.

[0189] The test results for the above five heavy metal elements in the raw ore of Wulancha crystal are shown in Table 9 below:

[0190] Table 9: Heavy Metal Element Detection Results of Wulan Tea Crystal Ore

[0191] Test item Test result (mg / kg) Pass or fail Lead (Pb) 28.2 Pass Cadmium (Cd) Not detected Pass Chromium (Cr) 12.8 Pass Mercury (Hg) Not detected Pass Arsenic (As) Not detected Pass

[0192] Note: The detection limit for the above five heavy metal elements is 0.01 mg / kg.

[0193] As can be seen from the results in Table 9, the test results of the above five heavy metal elements in the raw ore of Ulancha crystal stone fully meet the safety standards. Therefore, using the components processed from the raw ore of natural Ulancha crystal stone, namely Ulancha crystal stone B material and Ulancha crystal stone C material, as raw materials for the coating composition and components made of the present invention, ensures the safety of the product of the present invention in terms of heavy metal content and is a suitable raw material for making the coating composition and components made of the present invention.

[0194] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
