The invention relates to a method for preparing high washing resistance water-based paint by using regenerated building micro powder, which comprises the following steps: (1) 400-600 parts of regenerated building micro powder, 200-300 parts of emulsion, 3-8 parts of first functional auxiliary agents and 100-200 parts of deionized water are weighted according to parts by weight, fully mixed, then are put into a ball milling device for ball milling to obtain an aqueous coating slurry A; (2) 50-150 parts of deionized water and 22-32 parts of second functional auxiliary agents are added and fullymixed to obtain an aqueous coating slurry B; (3) finally, the aqueous coating slurry A and the aqueous coating slurry B are mixed and painted and sieved, and the obtained undersize object is the target product. Compared with the prior art, the preparation method has the advantages of simple preparation process, low production cost and small impact on the ecological environment, which not only solves the problem of large a
