[0002] Cement-based storage tanks are widely used in industrial and civil fields, mainly for storing liquids and solid materials. These tanks are usually used to store water, chemicals, petroleum products, food and beverages, etc., and are favored for their good structural strength and durability. Cement-based storage tanks can withstand environmental changes, withstand internal pressure, and prevent liquid leakage to a certain extent, ensuring the safety and stability of stored materials.

[0003] However, as time goes by and the temperature changes, there are some obvious deficiencies, which are mainly reflected in the following aspects:

[0004] Poor crack resistance: Cement-based materials are prone to cracks due to temperature changes, external stress and aging, which leads to reduced sealing of the tank and increased risk of leakage. Low toughness: The brittleness of traditional cement-based materials makes them easy to crack when subjected to impact or deformation, and cannot effectively protect the internal storage medium. Insufficient durability: During long-term use, the performance of cement-based storage tanks will degrade due to factors such as water penetration and chemical corrosion, affecting the service life of the tank. Summary of the invention

[0128] Experimental data table:

[0129]

[0130] Detailed performance analysis

[0131] The following is a detailed analysis of the performance data in the experimental group and the control group:

[0132] 1. Tensile strength (MPa)

[0133] Experimental group 1: 3.5

[0134] Control group 1:3.0

[0135] Analysis: The basalt fibers in Experimental Group 1 significantly improved the tensile strength, indicating that they exhibited better toughness and ductility when subjected to tensile stress. This enhancement effect is mainly attributed to the high strength characteristics of basalt fibers.

[0136] 2. Compressive strength (MPa)

[0137] Experimental group 2: 3.6

[0138] Control group 2: 3.2

[0139] Analysis: The compressive strength of experimental group 2 is higher than that of the control group, indicating that the penetrating crystalline additive enhances the density of the coating, making it more stable when under pressure. This is critical to the structural integrity of the tank.

[0140] 3. Anti-seepage performance (L / m 2 h)

[0141] Experimental group 3: 0.04

[0142] Control group 3: 0.05

[0143] Analysis: The anti-seepage performance of experimental group 3 is better than that of the control group. The reduced water permeability shows that the polymer emulsion improves the density and waterproof effect of the coating, and is suitable for applications requiring higher waterproof performance.

[0144] 4. Crack resistance

[0145] Experimental group 4: no cracks

[0146] Control group 4: with cracks

[0147] Analysis: There were no cracks in experimental group 4, indicating that the use of UV stabilizers effectively prevented material degradation caused by UV rays and maintained the structural integrity of the coating. This result emphasizes the importance of UV stabilizers in outdoor applications.

[0148] 5. Wear resistance (g)

[0149] Experimental group 1:4

[0150] Control group 1:5

[0151] Analysis: Although the wear resistance of experimental group 1 is slightly lower than that of the control group, considering its advantages in tensile and compressive properties, it means that although basalt fiber increases strength, it may compromise wear resistance. This needs to be balanced in practical applications.

[0152] 6. Flexibility (mm)

[0153] Experimental group 3: 2.5

[0154] Control group 3:2.0

[0155] Analysis: The addition of polymer emulsion in experimental group 3 makes the coating more flexible, able to adapt to stress changes caused by temperature changes, and reduce the risk of cracks.

[0156] 7. Weather resistance (hours)

[0157] Experimental group 4:320

[0158] Control group 4:290

[0159] Analysis: The improved weather resistance of experimental group 4 indicates that the addition of UV inhibitors can effectively extend the durability of the coating under UV radiation, thereby reducing material aging caused by UV rays.

[0160] Summarize

[0161] The performance comparison between the experimental group and the control group showed that specific ingredients (such as basalt fibers, penetrating crystallization additives, polymer emulsions and UV stabilizers) contributed significantly to the overall performance improvement of the coating.

[0162] Basalt fiber improves tensile strength and toughness, but is slightly inferior in wear resistance, showing the importance of balancing material properties.

[0163] The penetrating crystalline additive significantly improves the anti-seepage performance and is suitable for waterproof coatings.

[0164] The addition of polymer emulsion improves the flexibility of the coating and ensures stability in extreme climates.

[0165] Anti-UV agents effectively improve weather resistance and extend the service life of the coating.
