The invention discloses water-resistant white latex, which comprises the following main components: vinyl acetate, butyl acrylate, diacetone acrylamide, N-hydroxymethyl acrylamide, polyvinyl formal water agent, dibutyl phthalate, deionized water, initiator, defoamer, glycol alcohol, emulsifier, 2-amino-2-methyl-1-propanol. The white latex has the following advantages that: 1, polyvinyl formal is used as protective colloid to improve the water resistance of adhesive; 2, the diacetone acrylamide and the N-hydroxymethyl acrylamide are added as modification-polymerization monomer so as to increase crosslinking density and improve bonding strength; and 3, the butyl acrylate is added as the modification-polymerization monomer, and the copolymerization of the butyl acrylate and the vinyl acetatecan reduce the glass transition temperature and minimum film-forming temperature of the white latex, improve the low-temperature film-forming performance of emulsion and play a role in internal plasticization so as to increase the flexibility of the white latex.
