III, inorganic color stuffing is added：Calcium carbonate, blanc fixe, talcum powder, titanium dioxide, with more than 800r/min high speed dispersions,
Ensure that material dispersion is uniform；
IV, it when material is uniformly mixed and temperature of charge reaches 55 DEG C -60 DEG C under high velocity agitation, is ground while hot with triple-roller mill
Mill, fineness are ground to 100 μm；
V, by component A independent packaging；
(2) B component is prepared
1. preparing the raw material of B component by the weight percent
The weight percent of each raw material is in B component：
Polyphenyl polymethylene polyisocyanates 95%~97%；
Auxiliary agent II 0.5%~1.0%；
Carbon black 1.0%~5.0%；
The isocyano-content of the polyphenyl polymethylene polyisocyanates is 30.5%~32.0%；
The auxiliary agent II is dispersant, antifoaming agent and substrate wetting agents；
2. mixing and the packaging of B component raw material
It is ensured that all production equipments and utensil be not by Substances Pollutions such as water, alcohol, entire production process should be under nitrogen protection
It carries out；
I, polyphenyl polymethylene polyisocyanates are put into the container of another cleaning and are uniformly dispersed；
II, dispersant, antifoaming agent and substrate wetting agents are added in the polyphenyl polymethylene polyisocyanates of dispersion, then stir
It mixes and is dispersed to uniformly；
III, carbon black is added, is dispersed to uniformly；
IV, material is ground to the fineness that diameter is less than 20 μm with sand mill；
V, by B component independent packaging.
