[0024] A kind of preparation technology of vat brown RDL dye, comprises the steps:
[0025] Step 1: Take reduced brown G, reduced olive green, 1,4 aminoanthraquinone, 1-chloroanthraquinone, sodium fluoride, aluminum trichloride, dispersant, anti-coagulation additive, hydrogen peroxide, soda ash, copper chloride;
[0026] Step 2: Beat the raw materials and perform coarse filtration. The filtered fine materials are ground by an emulsification pump and a sand mill. The speed of the sand mill is 1300-1500r / s;
[0027] Step 3: Dry the ground slurry at a drying temperature of 120-160°C, and control the moisture after drying at 3%-5%;
[0028] Step 4: testing and packaging the dried raw materials to obtain vat brown RDL dye.
[0029] In step 2, the beating speed of the beater is 1300-1500 r / s.
