[0049] 1.1 Preparation of leafing powder aluminum pigment
[0050] 1) Add 500kg of S-150 aromatic hydrocarbon solvent into a ¢1000x1200mm stainless steel disc mixer, set the speed of the mixer to 120 rpm, and start stirring. Then add 200kg ZGP-04 type floating aluminum silver paste produced by Changsha Zuxing New Material Co., Ltd. in the mixer under stirring state, keep stirring for 3 hours. Among them, the main component of the S-150 aromatic hydrocarbon solvent is durene, with a distillation range of 180-210°C; the specific components of the ZGP-04 type floating aluminum silver paste are: 70wt% aluminum flakes, 2.4wt% stearin Acid and 27.6wt% C10 aromatics with a solids content of 72.4%, a particle size distribution with a D50 of 4um and an aspect ratio of 110:1.
[0051] 2) After the stirring is completed, pump the materials into the box-type filter press. After all the materials enter the filter press, turn on the compressed air and dry the filter cake in the filter pre...
