Abstract of  CN105694764 (A)：

The invention belongs to the field of polyurethane adhesives, and relates to fitting adhesives in fabric composition and underwear cup industries, in particular to a novel environment-friendly water-based single-component polyurethane adhesive and a preparation method thereof. The novel environment-friendly water-based single-component polyurethane adhesive is prepared from a polyurethane emulsion, an ethylene-vinyl acetate copolymer emulsion and an aid through compounding, the polyurethane emulsion is prepared from aliphatic polyester polyol, polyether polyol, hexamethylene diisocyanate, isophorone diisocyanate and matched aids; the aids mainly comprise an antifoaming agent and a thickening agent. The water-based single-component polyurethane adhesive is environment-friendly, safe, pollution-free, convenient to construct, high in composition efficiency, low in wastage, good in adhesive property, high in both initial and final adhesive strength, good in softness, excellent in yellowing resistance and good in washability and does not bubble and delaminate when washed at 40 DEG C.
