Abstract

The invention belongs to the technical field of pigment production, and particularly relates to a novel pigment based on light discoloration, and a preparation method thereof. The novel pigment is composed of a photochromic material, modified sodium oleate, a wetting agent, a defoaming agent, an adhesive, a retention aid and deionized water. The modified sodium oleate is obtained by grafting the potassium cinnamate on the sodium oleate, meanwhile, the photochromic material is obtained by utilizing the glycollic acid, the terbium salt and the phenanthroline, and the prepared novel color-changing pigment has good dispersity, high stability and a good antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of pigment production, in particular to a novel pigment based on light-changing color and a preparation method thereof. Background technique [0002] The world is colorful because of the color, and life is colorful because of the color, all of which come from the gift of nature and the ingenuity of human beings. With the rapid development of science and technology, human beings have been able to express and apply colors in various ways. Among them, the development and application of color-changing materials have brought us a refreshing "colorful" life. [0003] The photochromic pigment is added to the transparent resin to make a photochromic material, which can be used in sunglasses lenses, and has begun to be used in photochromic glasses in China. Linking photochromic pigments with high polymers can make materials with photochromic properties, which have great application prospects in photoelectric technol...
