Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-resistant high-strength water-based paint. Background technique [0002] Polyurethane (PU) refers to a general term for a class of polymers containing urethane bonds in the main chain of the molecule, usually produced by the polyaddition reaction of isocyanate and polyol. Water-based polyurethane uses water as the dispersion system instead of the organic solvent in solvent-based polyurethane. It is not only environmentally friendly, non-toxic and low in energy consumption, but also because the physical and chemical structure of the molecular chain remains unchanged, so that it can basically be compared with solvent-based polyurethane in terms of performance. comparable to. However, waterborne polyurethane has poor water resistance due to the introduction of hydrophilic groups and the use of water as a dispersion system. [0003] Water-based paint uses water as...
