[0014] As a further optimization of the present invention, the preparation process of the scratch-resistant agent is as follows: tin powder, titanium powder and reinforcing agent are mixed and stirred, the stirring time is controlled at 3-4 min and the stirring speed is controlled at 3-10 rps to obtain the scratch-resistant agent.

[0015] As a further optimization of the present invention, the preparation process of the reinforcing agent is as follows: (i) mixing rare earth cerium powder, rare earth praseodymium powder and rare earth erbium powder for 30-40 min and 10-13 rpm to obtain mixed powder; (ii) melting the mixed powder in a furnace for 2200-2250℃ and 40-50 min to obtain a mixed liquid; (iii) cooling and molding the mixed liquid to obtain rare earth blocks; (iv) grinding the rare earth blocks into powder with a particle diameter of 0.001-0.002 μm to obtain the reinforcing agent.

[0018] As a further optimization of the present invention, the preparation process of the waterborne polymer is as follows: waterborne epoxy powder, polyacrylamide and polyethylene oxide are mixed and stirred for 30-40 minutes and the rotation speed is controlled at 10-13 rpm to obtain the waterborne polymer.

[0019] The above-mentioned method for preparing a wall sealant includes the following steps:

[0165] III. Testing Experiments

[0166] 3.1 Diffusion test;

[0167] 1) Experimental materials: 1 dyne pen, 60 wall panels (10cm*10cm)

[0168] 2) Experimental steps:

[0169] ① A wall sealant prepared according to Examples 1-3 and Comparative Examples 1-3, numbered 1-6;

[0170] ② Divide the 60 wall panels into 6 equal parts, numbered 7-13;

[0171] ③ Apply a wall sealant prepared according to Example 1 evenly to wall panel No. 7, a wall sealant prepared according to Example 2 evenly to wall panel No. 8, a wall sealant prepared according to Example 1 evenly to wall panel No. 9, a wall sealant prepared according to Example 3 evenly to wall panel No. 10, a wall sealant prepared according to Comparative Example 1 evenly to wall panel No. 11, a wall sealant prepared according to Comparative Example 2 evenly to wall panel No. 12, and a wall sealant prepared according to Comparative Example 3 evenly to wall panel No. 13, and allow them to air dry naturally.

[0172] ④ Use a dyne pen to make a 1cm long and 1cm wide mark on each wall panel and let it air dry naturally;

[0173] ⑤ Record the proportion of the imprint area to the wall panel area for each wall panel, and take the average proportion of the imprints on all wall panels prepared in the same embodiment or comparative example, as shown in the table below:

[0174] project Average percentage of imprints (%) Example 1 1.3 Example 2 1.31 Example 3 1.04 Comparative Example 1 2 Comparative Example 2 1.7 Comparative Example 3 1.83

[0175] As can be seen from the table above, the wall sealant prepared in Example 3, compared with Examples 1-2 and Comparative Examples 1-3, is the best. The anti-diffusion agent prepared by combining an indium composition made of ethane sulfonic acid and butane sulfonic acid, a complexing agent made of quinoline and hydroxyquinoline, and a caustic alkali helps to prevent the diffusion of the mark left by the dyne pen, thereby helping to prevent the solution from stagnating on the wall surface and spreading, achieving the goal of reducing the area of ​​wall contamination and minimizing the damage to the aesthetics of the wall.

[0176] 3.2 Compression Test

[0177] 1) Experimental materials: 50 wall panels (1m*1m), 50 bricks (20cm*10cm*3cm) (5kg)

[0178] 2) Experimental steps:

[0179] ①A wall sealant prepared according to Example 3 and Comparative Examples 4-7, numbered 1-5;

[0180] ② Divide the 50 wall panels into 5 equal parts, numbered 6-10;

[0181] ③ Apply a wall sealant prepared according to Example 3 evenly to wall panel No. 6, apply a wall sealant prepared according to Comparative Example 4 evenly to wall panel No. 7, apply a wall sealant prepared according to Comparative Example 5 evenly to wall panel No. 8, apply a wall sealant prepared according to Comparative Example 6 evenly to wall panel No. 9, and apply a wall sealant prepared according to Comparative Example 7 evenly to wall panel No. 10.

[0182] ④ Slice each wall panel flat, then place a brick flat on each wall panel and leave it for 60 days before removing the bricks.

[0183] ⑤ Record the indentation depth of each wall panel, and take the average value of the indentation depths of all wall panels prepared in the same embodiment or comparative example, as shown in the table below:

[0184] project Average indentation depth (mm) Example 3 0.011 Comparative Example 4 0.17 Comparative Example 5 0.083 Comparative Example 6 0.078 Comparative Example 7 0.091

[0185] As can be seen from the table above, compared with Comparative Examples 4-7, the wall sealant prepared in Example 3 is the best. The reinforcing agent made of rare earth cerium powder, rare earth praseodymium powder and rare earth erbium powder, combined with the scratch-resistant agent prepared by tin powder and titanium powder, can effectively resist the pressure of bricks. This shows that the environmentally friendly sealant can effectively resist the squeezing force brought by furniture and avoid leaving indentations on the wall as much as possible.

[0186] Among them, water-based epoxy powder, as one of the core components of water-based polymer, has extremely low VOC emissions in its water-based system, meeting the environmental protection standards of modern architectural coatings. It does not contain organic solvents, avoiding irritating odors during construction. The epoxy groups provide strong polarity, enhancing penetration and anchoring to concrete or mortar substrates. It forms an interpenetrating network structure with acrylic esters, improving the overall adhesion of the sealant. It has excellent alkali resistance, preventing the precipitation of alkaline substances from the wall, and its hydrolysis resistance ensures long-term stability.

[0187] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
