Description

technical field [0001] The invention relates to the technical field of polyurethane coatings, in particular to an acrylic-polyaniline composite modified polyurethane coating. Background technique [0002] Polyurethane has good wear resistance, water resistance, solvent resistance and excellent mechanical properties. At present, it has been widely used in elastomers, foam plastics, coatings, adhesives and biomedical materials. Polyurethane coatings are usually used in leather finishing, textile printing and dyeing, paper making, architectural coatings, adhesives, cast steel coatings and other fields. Although polyurethane has excellent properties, it also has some limitations, for example, the hydrophilic -CH on its molecular chain 2 The OH group is easy to absorb water, which leads to the decline of the water resistance of polyurethane, which seriously affects the corrosion resistance and service life of the polyurethane coating in the water environment, thus limiting its a...
