Reactive moisture-curable polyurethane hot melt adhesive for 20D nylon super-splashing fabric

The invention discloses a reactive moisture-curable polyurethane hot melt adhesive for a 20D nylon super-splashing fabric. The reactive moisture-curable polyurethane hot melt adhesive comprises a main material and an auxiliary material, the main material comprises polyether polyol 1, polyether polyol 2, isocyanate and a chain extender; the auxiliary materials comprise a tackifier, a catalyst and a filler. Aiming at the problems that in the prior art, a polyurethane hot melt adhesive and a fabric are thin and easy to permeate, that is, a general polyurethane hot melt adhesive with relatively good flowability is relatively easy to permeate, and meanwhile, when the fabric is not twisted, the overall embedding force is relatively low, and the phenomenon of fabric adhesion layering is relatively easy to occur, the polyurethane hot melt adhesive is prepared by mixing polyether polyol 1 and polyether polyol 2; according to the present invention, the high-wettability and high-adhesion polyether polyol is formed, such
