UV super-hydrophobic polyimide paint prepared by room temperature reaction and used for wood material surface

The invention relates to a UV super-hydrophobic polyimide paint prepared by room temperature reaction and used for a wood material surface and a method. The paint is prepared from the following components: pyromellitic dianhydride, 4, 4'-diaminodiphenyl ether, N-methyl pyrrolidone, maleic anhydride, styrene, a photoinitiator, a leveling agent, 1, 4-diazabicyclo[2.2.2]octane, and a specially shaped carbon nanotube, wherein the photoinitiator is 1-hydroxy cyclohexyl phenyl ketone. According to the invention, room temperature reaction produces polyamic acid, polyamic acid then reacts with polyol to generate unsaturated polyester, also the photoinitiator, the leveling agent, 1, 4-diazabicyclo[2.2.2]octane, carbon nanotube and other raw materials are introduced to make the polyimide paint have super-hydrophobic property, and UV curing is carried out. The coating film applied to the wood material surface can achieve good sealing performance, super-hydrophobicity, temperature resistance, weather resistance and other excellent performance. Combined action of the three can cure polyimide, improve the curing speed and lower the curing temperature.
