Novel mildew-resistant asphalt paint and preparation method thereof

The invention relates to the technical field of building materials, and especially relates to a novel mildew-resistant asphalt paint and a preparation method thereof. The novel mildew-resistant asphalt paint is prepared from, by weight, 30-40 parts of a coal tar asphalt liquid, 15-25 parts of epoxy resin, 7-12 parts of zinc chromate, 20-25 parts of polyurethane, 10-15 parts of ethylene glycol, 1-3 parts of potassium chloride, 2-5 parts of sodium dodecyl benzene sulfonate, 8-11 parts of polyether acrylate, 2-6 parts of tetraethylammonium chloride, 2-7 parts of mica powder, 5-10 parts of an antiseptic, 3-7 parts of deionized water, 5-12 parts of aluminum powder, 3-5 parts of iron red, 1-6 parts of zinc yellow, 2-6 parts of ammonium bromide, 10-15 parts of tetraethylenepentamine, 2-5 parts of glycerol triacetate and 15-25 parts of xylene. The mildew-resistant asphalt paint with the advantages of simplicity in preparation, low cost, high and low temperature resistance, ageing resistance and good durability is pre
