Abstract

The invention discloses an irreversible photochromic coating and its preparation method. The coating is composed of the following components by weight part: 9.5-10.5 of amino organosilicon resin; 1.5-9 of a Keggin type heteropolyacid salt; 28-30 of ethyl acetate; 28-30 of cyclohexanone; 23.5-25.5 of talc powder; 1.0-1.6 of a dispersant; and 0.5-1.1 of a defoaming agent. The heteropolyacid salt refers to a material with a Keggin type structure, and its structural general formula is XM12O40<n->(X=P, Si; M=Cr, W, Mo, V, Nb, Ta, Ti or Zr, n=1, 2, 3...). In the invention, the organosilicon composition with an amino group is adopted to solve the problems that heteropolyacid compound color-changing materials are unstable and are likely to change color in use. The irreversible photochromic coating is especially suitable for automatic lineation and automatic printing.

Description

technical field [0001] The invention relates to coatings, in particular to an irreversible photochromic coating and a preparation method thereof. Background technique [0002] The research on photochromic materials has been continuously expanded and deepened in recent years, and the uses of photochromic materials are becoming more and more extensive, especially in the application of optical information storage, developing technology, and optical computing. In recent years, it has attracted attention at home and abroad. extensive attention. [0003] Heteropolyacid compounds belong to inorganic photochromic materials, which endow them with a series of advantages due to their unique composition and structure. It mainly has the following characteristics: large molecular volume; high molecular weight; transport and storage capacity for electrons and protons; high thermal stability: activity of "lattice oxygen"; high proton acidity; good solubility (can be used in many soluble i...
