Embodiment 1
[0017] A teak discoloration treatment method, comprising the following steps:
[0018] (1) Surface modification: under the catalyst of n-butyltin dilaurate, add cetyl alcohol solution in xylene dropwise in 4, 4' diphenylmethane diisocyanate at 52°C under slow stirring, in which 4, 4 'The molar ratio of diphenylmethane diisocyanate to cetyl alcohol is 1:1, and the mass ratio of cetyl alcohol to xylene in the xylene solution of cetyl alcohol is 10.5:100, then stir at constant temperature for 2 hours, and then add di Toluene solution with 0.12% sulfonyloxyketone, stirred evenly, to obtain the modified solution containing isocyanate groups, adding teak wood to the modified solution containing isocyanate groups and soaking for 40min, and then taking it out;
[0019] (2) Low-temperature plasma treatment: The teak treated in step (1) is subjected to low-temperature plasma treatment in the form of glow discharge. The treatment gas is argon. The surface is cleaned and dried;
