Yueyang Intech Materials Technology Co.,Ltd issued by the leadership of Dr Yi-fu zhang Ming patents of the new "cyclohexanone copolycondensation - melamine - formaldehyde resin and its preparation method", issued by the state intellectual property office has in August 2014, patent, patent number: CN103992454A. The invention discloses a kind of cyclohexanone copolycondensation - melamine - formaldehyde resin, melamine is under the action of catalyst after reaction with formaldehyde, add the cyclohexanone preparation for copolycondensation, described in the catalyst as a kind of alkali metal hydroxide, or a mixture of alkali metal hydroxide and its preparation method includes: adding melamine and formaldehyde in the reactor, join with catalyst to adjust pH value to 10-12, stirring up to 60-80 ℃, when pH is 10-12 keep temperature 0.5 2 h; To join the cyclohexanone, in 90-100 ℃ under stirring reaction 2-6 h; To join the deionized water, under the temperature 80-90 ℃, washed 2-6 times; After vacuum evaporation get cyclohexanone copolycondensation - melamine - formaldehyde resin. Resin of the preparation of the invention has good compatibility with the intermiscibility of solvents, resin, with a higher than cyclohexanone - formaldehyde resin glass transition temperature and softening point, better resistance to yellow degeneration, is a new type of paint/ink additives resin.
