Embodiment 1
[0022] A composite functional black dyeing agent of model F081-A was prepared. It is prepared from the following raw materials in parts by weight: 0.1 part of nano-calcium carbonate, 0.3 part of nano-montmorillonite, 6 parts of pigment carbon black, 0.1 part of dispersant, 0.1 part of lubricant, 0.01 part of defoamer, and 0.2 part of emulsifier part, 0.2 part of coupling agent.
[0023] The preparation method of the composite function black dyeing agent of model F081-A, carry out as follows:
[0024] Step 1: Pre-dispersion
[0025] Put nano-calcium carbonate and nano-montmorillonite in a high-speed mixer; add dispersant, lubricant, and stir at high speed for 1-3 minutes; then add coupling agent and continue stirring for 1-2 minutes; then add pigment carbon black , and continue stirring for 5-8 minutes, keeping the temperature at 25°C~45°C.
[0026] Step 2: Ball Mill Dispersion or Ultrasonic Dispersion
[0027] Put the material obtained in step 1 into a ball mill or ultraso...
