Problems solved by technology

The harsh environment of high temperature, high heat and high salt can easily lead to serious corrosion and rust on the surface of materials. At the same time, the special environment of high temperature and high humidity can easily lead to the growth of bacteria and mold on the surface of equipment, especially mechanical equipment in confined spaces. Hotbed, the rapid reproduction of bacteria and mold will not only accelerate the corrosion failure of materials, but also seriously affect the life and health of the staff; lead to a fire, and once a fire occurs, it will cause inestimable huge personal and property losses
[0003] In view of the above-mentioned problems, there are many functional coatings in the society, which can be used to solve the above problems respectively, but these functional coatings have a single function, and in order to achieve the purpose of comprehensive protection when using them, they need to be repeated many times outside the equipment. coating, and most paints will reduce their own protective effect when mixed, which greatly reduces the effectiveness of the paint and cannot provide long-term effective protection for equipment
For example, there are many manufacturers of tunnel decorative coatings in China. Although their decorative performance has reached a certain standard, the coating is relatively thick, and it is prone to mildew and peeling off under long-term humidity, and has no flame retardancy.

Abstract

The invention discloses an antibacterial mildew-resistant corrosion-resistant flame-resistant integrated nanometer functional paint, and preparation method and applications thereof. The antibacterialmildew-resistant corrosion-resistant flame-resistant integrated nanometer functional paint is mainly composed of a corrosion-resistant flame-resistant epoxy priming paint and an antibacterial mildew-resistant wear-resistant polyurethane finish paint. According to the preparation method, an intumescent flame retardant and graphene are added into the epoxy priming paint as flame retardation auxiliary agents; the paint flame resistance is improved greatly through the cooperative effect of the nanometer material and the intumescent flame retardant; nanometer silver antiseptic and hyperbranched polyethylene imide quaternary ammonium salt nanometer particles are added into the polyurethane finish paint as antibacterial auxiliary agents, and the paint antibacterial mildew-resistant performance isimproved through the cooperative effect of the nanometer silver antiseptic and the hyperbranched polyethylene imide quaternary ammonium salt nanometer particles. The reasonable combination of the priming paint with the finish paint is capable of improving the paint corrosion resistance further. The antibacterial mildew-resistant corrosion-resistant flame-resistant integrated nanometer functionalpaint possesses the antibacterial performance, the mildew resistance, the flame resistance, the corrosion resistance, and the wear resistance, is wide in application range, is simple in preparation method, is convenient in operation, and is convenient for large scale applications.
