The invention relates to the technical field of preparation of functional
coating, and provides a formula of
solvent-free thermal-spraying environment-friendly heavy anti-
corrosion coating which is quick to cure, energy-saving and environment-friendly, tough and wearable, strong in
adhesive force, good in
shock resistance and excellent in
corrosion resistance and a preparation method of the
coating. Each composition of primary
lacquer comprises liquid
epoxy resin, an active
diluent, auxiliaries, an anti-rusting
pigment, a
pigment, a filler and a thixotropic agent; each composition of a curing agent comprises amine resin, an active
diluent, an anti-rusting
pigment and a filler. The preparation method of the coating comprises the following steps: (1), preparing primary
lacquer, wherein the liquid
epoxy resin, the active
diluent and the auxiliaries are taken and added into a cylinder for stirring while the anti-rusting pigment, the pigment, the filler and the thixotropic agent are added to be uniformly dispersed, and then
grinding and filtering; (2), preparing the curing agent, wherein the amine resin, the active diluent, the thixotropic agent and the filler are added into the cylinder in sequence for dispersing at
low speed and then dispersing at high speed and filtering; and (3), carrying out mixed construction on the primary
lacquer and the curing agent by adopting a double-component airless
sprayer to form a coating layer.
