Fireproof bacteriostatic aqueous terrace paint used for bus and preparation method and application thereof

[0027] And, the embodiment of the present invention also provides a preparation method of a fire-resistant and antibacterial water-based floor coating for buses. The preparation method at least includes the following steps:

[0028] Step a. Weigh each raw material component according to the raw material formula of the above-mentioned fire-resistant and antibacterial water-based floor coating for buses, and mix 1 / 2-2 / 3 of the deionized water with 1 / 2-2 / 3 of the formula pH adjuster, dispersant, defoamer with 1 / 2 to 2 / 3 formula, nano alumina, nano zirconia, nano zinc oxide, flame retardant, silica sol, organic silicone powder, anion powder, pigment mix Evenly

[0029] Step b. Under stirring, add the aqueous epoxy emulsion, the film-forming aid, the remaining pH regulator, the remaining defoamer and the substrate wetting agent into the mixing container in sequence, and add them to the mixture obtained in step a after being uniformly premixed , Mix well, add thickener to adjus
