Embodiment 1
[0025] Embodiment 1, special fluorescent pigment for leather, raw material is made up of p-toluenesulfonamide, melamine, formaldehyde, polyurethane resin, and its proportioning is p-toluenesulfonamide:melamine:formaldehyde:polyurethane resin=1.0:0.8:0.6:0.3.
[0026] The molecular weight of the polyurethane resin is 3000-5000.
[0027] The preparation process of special fluorescent pigment for leather is:
[0028] 1. Add p-toluenesulfonamide, melamine and formaldehyde in proportion, and keep the temperature constant for 30 to 45 minutes at 80°C to 90°C.
[0029] 2. After the constant temperature is completed, add polyurethane resin, raise the temperature to 130°C-150°C, add basic dye 6GDN, basic dye 11:1, and keep warm for 1-1.5 hours.
[0030] 3. After the constant temperature is completed, the material is cooled and discharged.
[0031] 4. Material crushing and packing.
