b, performing a dispersing process by using an HMS-100 wet dispersing agent, wherein the aim is to enable the dispersing agent to replace air at the interface of the coating to enable the coating to be firmly combined, so as to fluidize the coating;
c, performing full reverse coating grinding on the high-pressure roller mill to obtain a thick film paint semi-finished product liquid with the coating thickness of 50 to 500 mu m;
d, diluting by adding 25% of diluent to obtain the paint leveling property according with the process ratio;
e, impurities in the semi-finished product coating can be concentrated on a filter screen to be removed through liquid centrifugal filtration, so that the semi-finished product coating is separated from the impurities;
f, packaging, namely placing the coating subjected to the processing procedure into a storage tank;
g is as follows 7:1, adding nano silicon dioxide into the coating in a proportion to improve the scrub resistance, the strength and the hardness of the coating;
s5, storage processing: and (5) storing the finished coating obtained in the step (S4) into a storage tank with the temperature of 15-25 ℃ to ensure the stability of the coating.
The methyl in the phenolic resin reacts with the light group and the epoxy group in the epoxy resin, and the phenol light group and the epoxy group in the phenolic resin perform ring-opening relay reaction.
The reaction speed of the aromatic amine with the epoxy group is slow. The electrons on the N atom are dispersed by the benzene ring to reduce the alkalinity, and the steric effect of the benzene ring is added.
