Abstract

The invention discloses a photochromic compound used for an ultraviolet intensity detection indication mark and a using method of the photochromic compound, relates to the photochromic compound used for the ultraviolet intensity detection indication mark and the using method of the photochromic compound, and aims to solve the problem that ultraviolet intensity cannot be understood in real time. The photochromic compound is a photochromic compound prepared from 2-(4'-N,N-dimethylaminophenylazo)anthraquinone yellow / red / blue photochromic compounds according to a mass ratio; and the using method comprises the following steps: modifying silicon dioxide sol, mixing the modified silicon dioxide sol and the photochromic compound, and performing photographing on colors under different radiation intensity to form a color-changing color gradation; and coating the modified silica sol on a fabric, and printing the color-changing color gradation to obtain ultraviolet intensity according to a color of the indication mark. The compound disclosed by the invention can accurately conveniently and quickly indicate the ultraviolet intensity in real time; and the compound is used in the field of spinning.

Description

technical field [0001] The invention relates to a photochromic compound used for ultraviolet intensity detection indicator marks and a use method thereof. Background technique [0002] The energy radiated by long-wave ultraviolet UV-A to people accounts for 98% of the ultraviolet energy radiated to people, and it is far deeper than UV-B in penetrating clothing and skin. UV-A can cause the transformation of the melanin matrix, so the melanin in the epidermis will produce rapid pigmentation within a few hours under its action, resulting in dark skin. These radiations can also cause accelerated aging of the skin, loss of elasticity, and the formation of wrinkles. Long-term accumulation can make the skin lose its luster. UV-A is the direct cause of melanoma skin cancer; UV-B can induce skin cancer and damage human DNA. This makes vigilance and UV protection imperative. Ultraviolet rays cannot be seen or touched. How can we know or judge the strength of ultraviolet rays in the...
