preparation example Construction

[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.

Abstract

The present invention discloses a vat brown RDL dye and a preparation process thereof, and belongs to the technical field of vat dyes. The vat brown RDL dye comprises, in parts by weight, 18-23 partsof vat brown G, 2-5 parts of vat olive green, 10-15 parts of 1,4-aminoanthraquinone, 12-17 parts of 1-chloroanthraquinone, 1-3 parts of sodium fluoride, 2-5 parts of aluminum trichloride, 0.1-1 part of dispersant, 0.1-1 part of anti-coagulation aid, 40-45 parts of hydrogen peroxide, 1-2 parts of sodium carbonate and 1-2 parts of copper chloride. The vat olive green and the vat brown G are added and fused with each other, so that the color fastness of the vat brown RDL dye can be enhanced; and meanwhile, the permeability of the vat brown RDL dye can be enhanced by adding the sodium carbonate and the copper chloride, and the dyeing effect of the dye is accelerated.
