Problems solved by technology

The function of the hydrophobic coating currently used is generally relatively single. Although some researches have added antibacterial and antiviral components to the hydrophobic coating to realize the integrated integration of hydrophobic function and antibacterial and antiviral function, the antibacterial and antiviral active components are easy to be in large quantities. Dissolution and loss lead to insufficient or loss of antibacterial and antiviral capabilities. Therefore, it has become a development work of great significance to construct a hydrophobic coating system with high efficiency, good stability, long service life, and good antibacterial and antiviral effects.

Embodiment 1

[0025] The method of preparing the modified fluorosilane composite sol, and the specific embodiments include:

[0026] 1. Based on mass parts, 2 parts of the copperide of 2 parts having a average particle diameter of 200 nm and a titanium dioxide having an average particle diameter of 100 nm are mixed in a ball mill under a ball mill, and a copper phosphate is doped. Modified titanium dioxide, by spherical milling, causes copper phosphate to be doped in titanium dioxide to obtain a modified titanium dioxide having a smaller particle size, and the average particle diameter obtained in the modified titanium dioxide obtained in this example is 50 nm;

[0027] 2. The modified titanium dioxide, 20 parts of methacrylate, and 15 parts of vinyl trimethoxysilane and 1 part initiator BPO were dispersed in 40 parts of ethanol at 60 ° C for 4 h in 40 ° C. The entire reaction process was stirred, and the precipitate in the mixed solution was collected, and the precipitate was dried to give a m...

Embodiment 2

[0035] The steps of this embodiment are substantially identical in the first embodiment, and the difference is that the three parts of the average particle diameter of 500 nm of titanium dioxide and 30 parts of the average particle diameter of 200 nm are mixed in the weight parts of the weight parts.

Abstract

The invention discloses a modified fluorosilane composite sol, a preparation method thereof, a coating containing the modified fluorosilane composite sol, a preparation method and an application thereof. The modified fluorosilane composite sol includes 2-3 parts of nano-transition metal phosphate, 30-40 parts of nano-titanium dioxide, 20-30 parts of organic fluorine monomer, 15-20 parts of silane coupling agent, and 1-3 parts of initiator BPO And 50-60 parts of hydrophilic dispersant. The thermosetting resin, the modified fluorosilane composite sol and the organic solvent are mixed, stirred until fully dissolved, and the coating is obtained. The coating formed by the coating of the present invention has good adhesion to the substrate; the coating has high-efficiency hydrophobicity, which can effectively reduce the adhesion of viruses; photocatalytic reactions can occur under visible light irradiation, thereby effectively killing viruses Or bacteria, so that the coating has excellent antiviral and antibacterial properties; and the antibacterial and antiviral active components will not be dissolved and lost in large quantities, and the antibacterial and antiviral effect is stable, which can greatly increase the effective service life of the antibacterial and antiviral coating.

Description

Technical field [0001] The present invention relates to the field of antibacterial antiviral technologies, and more particularly to modified fluorosilane composite sol, and the preparation methods thereof and coatings containing the modified fluorosilane composite sol therefor and their preparation methods. Background technique [0002] In recent years, the epidemiological virus has been made due to highly pathogenic viruses such as influenza viruses and new coronavirus and some of the pathogenesis of germacteria. Public places such as hospitals, schools and other people have become a place where they are very easy to explode, especially in public health facilities such as hospitals, the possibility of viruses and pathogens is extremely high, and the health is extremely harmful to the public. In addition, in some special medical devices such as the use of dialyzers, the viral cross infection caused by disinfection is also a potential threat. Therefore, a broad-spectrum antibacter...
