Embodiment 1
[0040] Weigh 5g of sodium dodecylbenzenesulfonate, dissolve it in 300ML water, pour it into a container, and then add 40g of methyl alcohol dissolved with 0.6g of 2,2-azobisisobutyronitrile and 20g of oil-soluble blue into the container Methyl acrylate; N into the vessel 2Oxygen was removed, the container was placed in a constant temperature water bath, the temperature was raised, and constant stirring was maintained throughout the reaction process, and the reaction was continued for another 6 hours when the temperature reached 60°C. After the reaction, the prepared microsphere suspension was poured into a beaker and allowed to stand for stratification. After standing and stratifying, pour off the upper liquid, dilute the precipitated color paste with water, and then let it stand and separate for washing. After repeated washing for three times, a micron-sized polymethyl methacrylate microsphere slurry will be formed. ; Then add 1g xanthan gum and 0.5g polyquaternium salt to t...
Embodiment 2
[0042] Take by weighing 15g sodium lauryl sulfate, be dissolved in 1000ML water, pour in the container, then add 140g to be dissolved in the container and have 2.8g 2, the formazan of 2-azobisisobutyronitrile and 70g oily fluorescent pigment (pink) butyl acrylate; N into the vessel 2 Oxygen was removed, the container was placed in a constant temperature water bath, the temperature was raised, and constant stirring was maintained throughout the reaction process, and the reaction was continued for another 6 hours when the temperature reached 60°C. After the reaction, the prepared microsphere suspension was poured into a beaker and allowed to stand for stratification. After standing and stratifying, pour off the upper liquid, dilute the precipitated color paste with water, and then let it stand and separate for washing. After repeated washing for three times, a micron-sized polybutylmethacrylate microsphere slurry will be formed. ; Then add 3.5g xanthan gum and 1.5g polyquaterni...
