A preparation method for canned two dimension solidification environmentally-frieweak weak solvent type tough epoxy anticorrosive coating, it is characterized in that, the method comprises the following steps:
1) modified epoxy solution is mixed in scuffing of cylinder bore;
2) in mark machine, mineral dye, dewatering agent, solvent under stirring, is added;
3) these compounds disperseed in sand mill and reach 40 microns;
4) add solidifying agent mix and blend again, obtain product.
Compared with prior art, have the following advantages:
(1) one-pot uses degree, and can opening both can application, without the need to matching while using;
(2) without the solvent that triphen class is harmful to environment or human body, use environment or the lighter Weak solvent of human toxicity;
(3) adopt the crosslinked and active ingredient cross-linking reaction dual cure mechanism of unsaturated link(age), make coating structure finer and close, considerably improve its resistance to corrosion factor and other chemical;
(4) owing to have employed increasing tougheness stem material, the fragility of corrosion-resistant epoxy paint is improved greatly.
