Description

Technical Field

[0001] The present invention relates to the field of fluorine-containing coating materials, and in particular to a wear-resistant anti-fingerprint liquid fluorine-containing coating material, a preparation method and an application thereof. Background Art

[0002] In order to improve the anti-fingerprint and anti-fouling properties of materials such as plastic, glass, and metal, a thin film of coating material is usually applied by spraying anti-fingerprint liquid. Anti-fingerprint liquid is widely used in touch screen devices such as mobile phones, cameras, and glasses. It can effectively reduce the adhesion of fingerprints and oil stains, maintain the smoothness and aesthetics of the product surface, and enhance user experience. In addition, using anti-fingerprint liquid on household appliances such as refrigerators, washing machines, microwave ovens, and kitchen equipment can reduce the adhesion of fingerprints and oil stains, keep the equipment clean and beautiful for a long time, and reduce the difficulty and frequency of cleaning. The main performance indicators of anti-fingerprint liquid are: (1) extremely low surface tension, good hydrophobic effect, and anti-fingerprint staining effect; (2) good wear resistance and long-lasting anti-fingerprint effect; (3) low dynamic friction coefficient and high smoothness.

[0003] Commonly used anti-fingerprint liquids are typically composed of fluorinated polymer molecules, which form a coating on the surface that is difficult for skin oils and other dirt to adhere to. This coating has excellent hydrophobicity, wear resistance, and scratch resistance, protecting the substrate surface from damage. It also has good transparency and adhesion, and is not easy to fall off. Fluorinated anti-fingerprint liquids achieve excellent anti-fouling properties through the synergistic effect of fluorine and silicon. However, the ordinary coatings of anti-fingerprint liquids currently on the market are only durable for 3,000 abrasions and have poor strength indicators. Therefore, with the growing demand for anti-fingerprint liquids in various applications, the market needs a coating material prepared with fluorinated anti-fingerprint liquids that can simultaneously achieve high wear resistance and high strength.

[0020] Step 1: Weigh ethyl acrylate, methyl methacrylate, 2-hydroxyethyl methacrylate, 1H,1H,2H,2H-hexafluorobutyl acrylate, fluorine-containing allyl benzoxazine, an adhesive, and a solvent according to parts by weight, mix them, and stir at a speed of 400 - 600 r / min for 5 - 10 min to obtain a mixed liquid A;

[0022] Step 3: Coat the mixed liquid B on a degreased substrate with a coating thickness of 5 - 100 μm, then place it in an oven at 50 - 80 °C for 1 - 5 min, and then place it under an ultraviolet lamp with a light intensity of 500 - 1000 mJ / cm 2 for curing to obtain a fluorine-containing coating material for an anti-fingerprint liquid.

[0023] In a third aspect, the present invention provides the use of a fluorine-containing coating material for an anti-fingerprint liquid with wear resistance as an anti-fingerprint coating in the fields of plastic, glass, or metal materials.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention prepares a coating material for an anti-fingerprint liquid, using three acrylates (ethyl acrylate, methyl methacrylate, 2-hydroxyethyl methacrylate), 1H,1H,2H,2H-hexafluorobutyl acrylate, and fluorine-containing allyl benzoxazine as monomer compounds, and simultaneously adding an initiator and various additives to prepare the anti-fingerprint liquid. After the anti-fingerprint liquid is treated by UV light irradiation, polymerized, and cured, the obtained fluorine-containing coating material, compared with traditional acrylic anti-fingerprint materials, not only has the advantages of high temperature resistance and solvent resistance, but also shows stronger hydrophobicity and more excellent wear resistance.

[0026] 2. The three acrylates added to the anti-fingerprint liquid in the present invention, ethyl acrylate (EA) has good adhesion to various substrates, methyl methacrylate (MMA) has good rigidity and surface hardness, and 2-hydroxyethyl methacrylate can adjust the coating flexibility to reduce the risk of brittle cracking.

[0027] 3. 1H,1H,2H,2H-hexafluorobutyl acrylate introduced into the anti-fingerprint liquid of the present invention contains abundant fluorine elements. After curing, fluorine atoms are enriched on the coating surface, showing excellent hydrophobicity and stain resistance. At the same time, the present invention also introduces fluorine-containing allyl benzoxazine, which combines the high performance of benzoxazine and the unique advantages of fluorine elements, endowing the coating with higher hardness and wear resistance, as well as excellent heat resistance and thermal stability.

[0028] 4. The fluorine-containing allyl benzoxazine is prepared by Mannich condensation reaction with magnolol, 4-amino-2,5,6-trifluoropyrimidine and paraformaldehyde as reactants. Among them, magnolol containing allyl participates in the reaction as a phenol, and 4-amino-2,5,6-trifluoropyrimidine containing fluorine element participates in the reaction as an amine. The finally obtained benzoxazine compound contains fluorine group, allyl group and pyrimidine group at the same time. The allyl group can participate in the polymerization reaction of acrylic acid as an unsaturated bond. The trifluorine group endows the material with stronger hydrophobicity and lower surface tension, and the high-rigid structure of the pyrimidine ring can significantly improve the hardness and wear resistance of the coating.
