Abstract

The invention relates to no-curing high-performance ceramic water-based paint and a preparation method thereof. The coating has is composed of an A component, a B component and a C component; the A component is prepared by mixing the following raw materials, in parts by weight: an acidic silica sol, an acidic aluminum sol, an acidic zirconium sol or a mixture of the acidic silica sol, the acidic aluminum sol and the acidic zirconium sol in any ratio, deionized water and an alcohol solvent, and performing dispersion; the B component is composed of the following materials: methyltrialkoxysilane,phenyltrialkoxysilane, tetraalkoxysilane, dimethyldialkoxysilane, diphenyldialkoxysilane, a silane coupling agent, an non-sticking auxiliary agent and a catalyst; and the C component is prepared by mixing the following raw materials: deionized water, isopropanol or ethanol, an acidic silica sol, a neutral silica sol or a mixture of the acidic silica sol and the neutral silica sol in any ratio, aninorganic filler, a coloring pigment, a toughening emulsion, a dispersant and other auxiliary agents, and performing dispersion. The paint provided by the invention does not need curing, has simple and convenient construction, excellent performance and good environmentally-friendly performance, and is easy to produce in a large scale, thereby being a novel high-performance water-based coating.

Description

technical field [0001] The invention relates to the field of new fluorosilicon materials, in particular to a curing-free high-performance ceramic water paint and a preparation method thereof. Background technique [0002] Under the background of my country's unprecedentedly strict environmental protection policies and people's increasing awareness of safety and health, high-performance water-based paints that use water as a dispersion medium and water-soluble / water-dispersible resins as film-formers have ushered in unprecedented opportunities for development. Nano-ceramic coatings are made of siloxane monomers or oligomers, supplemented with inorganic nanoparticles and high-temperature-resistant pigments and fillers, prepared by the sol-gel method, showing many common water-based coatings and even solvent-based coatings. Advantages, such as high temperature resistance, flame retardant and smokeless, high hardness, friction resistance, excellent weather resistance and gloss a...
