Abstract

The invention relates to environmentally-friendly organic photochromic aqueous polymer paint and a preparation method thereof. The preparation method comprises the following steps of emulsion preparation, initiator preparation, acrylic acid emulsion synthesis and organic photochromic aqueous paint preparation. The characteristic of the environmentally-friendly organic photochromic aqueous polymer paint is determined by a photochromic compound in the system, under the excitation action of ultraviolet ray, a C-O bond of the colorless photochromic compound fractures and causes isomerization and rearrangement of a molecular structure and electron configuration, two circular systems connected by C atoms are in a coplane state changed from an orthogonal state and form a large conjugated system which is a blue color body, and after ultraviolet ray elimination, a cyclization reaction occurs and the blue color body becomes colorless so that a reversible photochromic system is formed. The environmentally-friendly organic photochromic aqueous polymer paint is environmentally friendly and nontoxic and photochromism is a reversible chemical reaction.

Description

technical field [0001] The invention belongs to the field of functional polymer materials, and specifically relates to an environment-friendly organic photochromic water-based polymer coating and a preparation method thereof, which are mainly used in baby carriage materials, and can present colorful and gorgeous patterns or patterns under light, making baby carriages It is more popular with children. Background technique [0002] Baby carriages have developed by leaps and bounds in our country, and all kinds of baby carriages emerge in an endless stream. Baby stroller is an indispensable child-rearing tool for modern families and plays an important role in modern family life. However, with the improvement of people's living standards, people have put forward higher and higher requirements for existing baby carriages. New types of baby carriages such as safe, functional, and colorful are more popular with children and parents, especially the distinctive ones. stroller. Pre...
