Technical Field
The invention relates to the technical field of coatings, and particularly relates to a water-based cationic acrylic polymer woodware varnish and a preparation method thereof.
Background
With the health pursuit of consumers, interior wood finishing, and furniture surface coating begin to become increasingly water-based. Meanwhile, since the 21 st century, environmental protection laws of various countries limit VOC, solvent-based coatings are used, the solvents are volatile and have pungent smell, a large amount of toxic and harmful gas is generated in the drying process, and not only is the harm to human health generated, but also the serious burden is brought to the global environment. These factors are all accelerating the pace of oil-to-water conversion. The waterborne wood decorative coating eliminates the harm of organic solvent to human body, is low-carbon and environment-friendly, has high safety performance, and is popular with people. At present, the water-based wood paint is an anionic water-based single/double-component system. The single-component anion system is simple in construction, but has general performance, and although the performance of the double-component anion system is improved compared with that of the single-component anion system, the following problems still exist: 1) the hardness is slowly established, and the final hardness is low; 2) the fullness of the paint film is poor; 3) the transparency is general; 4) carbon dioxide is generated by reaction with an isocyanate curing agent, so that the paint film is easy to have defects; 5) the drying time is slow; 6) the activation period is short, which causes waste; 7) on looser solid wood, the expansion-preventing ribs are poor. The development of the water-based wood paint is severely restricted by the problems of the anionic two-component paint.
