Difficult-to-fade pigment and preparation method thereof

The invention relates to the field of pigments, and particularly discloses a difficult-to-fade pigment and a preparation method thereof. The pigment is prepared from the following raw materials: 20 to 30 parts of organic pigment, 40 to 60 parts of acrylic ester, 5 to 10 parts of modified titanium dioxide and 1 to 5 parts of other auxiliary agents, the preparation method comprises the following steps: mixing the organic pigment with other assistants, adding the acrylate and the modified titanium dioxide into the mixed solution, stirring at room temperature, and carrying out ultrasonic dispersion to obtain the pigment which is not easy to fade. According to the difficult-to-fade pigment disclosed by the invention, by modifying the titanium dioxide, the dispersity of the titanium dioxide in a pigment system is improved, so that the pigment has relatively good ultraviolet resistance, the weather resistance of the pigment is enhanced, and the color fading phenomenon of the pigment is reduced. 本申请涉及颜料领域，具体公开了一种不易褪色
