NOVELTY - Two-component aqueous asphalt coating comprises 100 pts. wt. component (A) comprising 100 pts. wt. composite latex and 30-160 pts. wt. composite asphalt emulsion, and 30-60 pts. wt. component (B) comprising 10-50 pts. wt. deionized water and 0.1-2 pts. wt. curing agent, where the composite latex comprises 5-30 pts. wt. fluororubber 246 latex, 5-10 pts. wt. vinylidene rubber latex, 2-20 pts. wt. styrene butadiene rubber latex and 2-20 pts. wt. butyl latex, and the composite asphalt emulsion comprises 5-15 pts. wt. No. 50 asphalt emulsion, 5-25 pts. wt. No. 70 asphalt emulsion, 5-20 pts. wt. No. 90 asphalt emulsion, 5-10 pts. wt. No. 110 asphalt emulsion, 5-20 pts. wt. filler, 1-5 pts. wt. flame retardant, 1-5 pts. wt. light stabilizer and 2-5 pts. wt. film-forming stabilizer. USE - The coating is useful for container floor. ADVANTAGE - The coating has excellent environmental protection performance and shortens the container's flavor time. The method has simple preparation and easy mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the two-component aqueous asphalt coating for container floor, involving (i) weighing fluororubber 246 latex and vinylidene rubber latex, stirring for 10-30 minutes, adding accurately measured styrene-butadiene latex and butyl latex, and stirring for 10-30 minutes to obtain a composite latex, (ii) weighing No. 50 bitumen emulsion, No. 70 bitumen emulsion, No. 90 bitumen emulsion and No. 110 bitumen emulsion, stirring for 10-30 minutes, adding filler, flame retardant, light stabilizer and film stabilizer in sequence, and stirring for 10-30 minutes to obtain composite asphalt emulsion, and (iii) stirring and mixing the composite latex and the composite asphalt emulsion for 10-30 minutes to obtain the target product.
