Tunnel decorative coating, preparation method and application thereof

The invention provides a tunnel decoration coating, a preparation method and application thereof, and the tunnel decoration coating comprises the following components by mass: 45-50% of acrylic acid-epoxy bi-component resin, 5-8% of an adhesive-film-forming agent, 2-5% of a dispersant, 4-7% of a nanofiller, 1-2% of an antifoaming agent, 2-3% of titanium dioxide, and 30-35% of a first solvent; wherein the dispersing agent comprises hydrophobic anionic sylvite, the first solvent comprises water, and the nanofiller comprises 25%-30% of nanosilicon dioxide, 20%-25% of graphene oxide, 25%-30% of carbon nanofibers and 20%-25% of montmorillonite; the particle size of the nano filler is 60 to 90 nm. On the basis of the existing tunnel fireproof coating, the performance optimization can be realized by repairing the aged and damaged parts of the existing tunnel fireproof coating. The method is easy to operate, remarkable in effect and worthy of popularization. 本发明提供了一种隧道装饰涂料、制备方法及其应用，按质量分数计，隧道装饰涂料组成包括：丙烯酸-环氧双组分树脂45～50％
