Description

Technical Field

[0001] This application relates to the field of water-based coatings technology, and more specifically, to a friction-resistant and corrosion-resistant coating and its manufacturing process. Background Technology

[0002] Coatings are a widely used method of corrosion protection, with common types including oil-based and water-based coatings. Oil-based coatings, traditional coatings, contain organic solvents, which can easily cause air pollution during use due to their volatilization. Water-based coatings, on the other hand, are environmentally friendly, containing no organic solvents and are non-toxic and safe to apply, thus gaining widespread attention and application. Water-based coatings are classified by performance into anti-corrosion coatings, insulating coatings, high-temperature resistant coatings, and aging-resistant coatings. Anti-corrosion coatings are already used in industrial equipment, bridges, ships, and other fields, providing protection to the substrate, achieving good corrosion resistance, and extending the service life of equipment or structures. Existing anti-corrosion coatings often use water-based acrylic emulsions as raw materials, with added wetting and dispersing agents, film-forming aids, and substrate wetting agents. While these coatings offer good corrosion resistance, the complexity and diversity of the external environment mean that the paint film may crack due to friction, and in severe cases, delamination may occur, indicating limited abrasion resistance, which still needs improvement. Summary of the Invention

[0003] To improve the abrasion resistance of abrasion-resistant and anti-corrosion coatings, this application provides an abrasion-resistant and anti-corrosion coating and its manufacturing process.

[0004] In a first aspect, this application provides a friction-resistant and corrosion-resistant coating, which adopts the following technical solution: A friction-resistant and corrosion-resistant coating is mainly made of the following raw materials in parts by weight: 50-70 parts of water-based acrylic emulsion, 20-40 parts of water-based epoxy emulsion, 5-15 parts of water-based fluorocarbon emulsion, 9-11 parts of modified silica, 2-4 parts of adipic dihydrazide, 4-6 parts of oleic acid, 1-3 parts of wetting and dispersing agent, 2-4 parts of film-forming aid, 1-3 parts of substrate wetting agent, 0.5-1.5 parts of anti-settling agent, 0.5-1.5 parts of defoamer, and 55-65 parts of deionized water; The modified silica is obtained by treating silica with γ-piperazinylpropylmethyldimethoxysilane, N-(N-acetylleucyl)-3-aminopropyltriethoxysilane, 3-(methacryloyloxy)propyltrimethoxysilane, and diacetone acrylamide.

[0005] The friction-resistant and anti-corrosion coating of this application, through the mutual combination of raw materials, achieves an impact resistance >60cm, tensile strength >8MPa, hardness of 5H, and friction mass loss <0.7mg / 1000r, exhibiting the advantages of high impact resistance, strong adhesion, and good friction resistance, which can meet market demands.

[0006] The friction-resistant and anti-corrosion coating of this application uses water-based acrylic emulsion, water-based epoxy emulsion, and water-based fluorocarbon emulsion as base raw materials, and adds modified silica, adipic acid dihydrazide, and oleic acid to these bases. In the modified silica, γ-piperazinylpropylmethyldimethoxysilane, N-(N-acetylleucyl)-3-aminopropyltriethoxysilane, 3-(methacryloyloxy)propyltrimethoxysilane, and diacetone acrylamide are grafted onto the silica surface, and active groups such as primary amine groups, secondary amine groups, amide groups, ester groups, and ketone carbonyl groups are introduced. The ketone carbonyl groups in the modified silica can react with the amino groups in the adipic acid dihydrazide, increasing the crosslinking density and enhancing the performance of the coating film. Furthermore, the synergistic effect between the modified silica and oleic acid is utilized to increase the interaction and bonding force between the raw materials, improving the overall integrity of the coating film. This results in higher impact resistance, tensile strength, and friction resistance, and also gives the coating film a smooth, glossy, and aesthetically pleasing appearance.
