Background technology
It is further perfect with environmental regulation, for the purpose of mitigating earth load, low VOC or Diamond Search discharge it is new
Coating becomes the hot spot of research and development, and the research and development of water-based timber coating are more noticeable.
Recent years, China is very active on the research and development of water-borne wood coating technology, especially with water-borne acrylic coatings
For the water paint of representative, technical merit also improves quickly, it was reported that and Chinese timber coating has the market of few hundred thousand tonnes of every year,
If water-based timber coating can substitute solvent wood coatings, its environmental-protection function and economic results in society are very significant.
But current water-borne acrylic coatings are there are poor adhesive force, the shortcomings that salt water resistance can not meet demand, it would be highly desirable to improve.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of resistant to saline solution water-borne acrylic coatings, institute
It is excellent to obtain the curing performance of coating, painting film density is big, and adhesive force is excellent, and salt water resistance is high, while overcomes coating flowing hanging
Phenomenon, service life length.
A kind of resistant to saline solution water-borne acrylic coatings proposed by the present invention, its raw material include by weight：Water-base epoxy changes
