The invention relates to the technical field of
chemical production, in particular to high-dispersion pearlescent color oil for plastics and a preparation method thereof.The pearlescent color oil comprises 50%-97.5% of
grease, 2%-50% of pearlescent toner and 0-10% of auxiliaries, the
grease is a
compound system of carbomer and the like, and the auxiliaries comprise a dispersing agent, an
antioxidant and an anti-UV agent; the preparation method comprises the steps of
raw material pretreatment, mixing, quantitative dispersion and curing post-treatment, and the dispersion uniformity coefficient sigma is controlled to be smaller than or equal to 0.3 by determining the dispersion rotating speed and time. Through
raw material optimization and process quantitative regulation and control, the color oil
dispersion stability is improved, the color
oil can adapt to PP, PET, ABS and other plastics, the appearance can be ensured to be uniform and free of flow lines under the condition of low addition amount, and the color oil has good
weather resistance. The process is high in
operability, does not need special equipment, is suitable for industrial
mass production, and provides a high-quality solution for plastic decoration.
