The invention discloses a high-
viscosity water-based suede-like water-based resin. The high-
viscosity water-based suede-like water-based resin is prepared from, by weight, waterborne
polyurethane resin, matting
powder, foam
powder, deionized water, suede
powder and a
thickening agent and can also be prepared from a carbon
fiber part, a spandex
fiber part, a raw bamboo
fiber part and a
coupling part; the waterborne
polyurethane resin is prepared from polyether
polyol,
polyester polyol,
isocyanic acid, deionized water, a primary chain
extender and a secondary chain
extender, wherein the primarychain
extender is prepared from 2,2-dihydroxymethyl
butyric acid, tributylmethoxy
tin and methyl fluoronic acid, and the secondary chain extender is selected from amine chain extenders. The preparation method comprises the steps that the
isocyanic acid is added for a reaction after the polyether
polyol and the
polyester polyol are dehydrated; the primary chain extender is added, and
ammonium hydroxide is added, so that
neutralization is performed to generate salt, and partial deionized water is added while
cutting is performed at a high speed for mixing; the secondary chain extender is added,the deionized water is added while stirring is performed at a
low speed, and standing is carried out to obtain the waterborne
polyurethane resin, and the waterborne polyurethane resin continues to bemixed with remaining components of the high-
viscosity water-based suede-like water-based resin to obtain the high-viscosity water-based suede-like water-based resin.
