Abstract of  CN105601878 (A):

The invention belongs to the technical field of paints, and discloses a nano cellulose whisker grafted water-diluted photocuring PUV (polyurethane acrylate) resin, and preparation and application thereof. The preparation method comprises the following steps: reacting aromatic or aliphatic diisocyanate with polyoxypropylene diol to obtain a polyurethane prepolymer I, sequentially reacting the polyurethane prepolymer I with dimethylolpropionic acid, nano cellulose whiskers, 2-hydroxypropyl acrylate and a pentaerythritol triacrylate mixture to obtain a nano-cellulose-whisker-containing PUV prepolymer, neutralizing the prepolymer, diluting with water, and removing the acetone solvent to obtain the product. The nano cellulose whiskers are subjected to graft polymerization reaction with NCO and OH groups onto the polyurethane prepolymer molecular chain, so that the obtained product has very high photocuring speed, excellent adhesive force, favorable storage stability and favorable water resistance. The tensile strength of the photocured paint film can reach 15.51 MPa, and the paint film has favorable mechanical properties.
