Blue light converter, blue light resistant adhesive, blue light resistant tape, and preparation method thereof

Abstract

The invention relates to a blue light converter, a blue light resistant adhesive, a blue light resistant tape, and a preparation method thereof. The blue light converter is composed of following raw materials in parts by weight: 0.5 to 1.0 part of rare earth compounds, 3 to 5 parts of alkyl compounds, and 6 to 10 parts of quinoline compounds. The preparation method of the blue light converter comprises following steps: adding rare earth compounds, alkyl compounds, and quinoline compounds into a ball mill according to the ratio mentioned above, ball-milling the raw materials, and finally carrying out vacuum drying to obtain the blue light converter. Compared with the prior art, rare earth compounds are modified by the alkyl compounds and quinoline compounds to prepare the novel blue light converter; and solved are the problems that a conventional blue light absorbent pollutes the environment, if the addition amount of a conventional blue light converter is small, the blue light conversion effect is not good, but if the addition amount of the conventional blue light converter is large, the performance of the converter is severely influenced. The invention further provides a high performance blue light resistant adhesive and a blue light resistant tape.

Description

technical field [0001] The invention relates to the technical field of light-shielding tapes, in particular to a blue light conversion agent, an anti-blue light adhesive, an anti-blue light tape and a preparation method thereof. Background technique [0002] The main function of the light-shielding tape is to fix the LCD screen and the backlight module. One of its main functions is to block the excess light leaking from the edge of the optical film. In the ultra-narrow bezel screen design, the width of the light-shielding tape is very narrow, resulting in Part of the light is refracted into the screen through the transparent adhesive layer, causing a bright line to appear on the edge of the screen, which affects the display effect. At the same time, the blue light in the excess light will cause damage to the eyes of the human body. [0003] At present, the anti-blue light materials on the market are mainly realized by adding blue light absorbers or blue light conversion agen...

AI Technical Summary

Problems solved by technology

[0004] However, blue light absorbers such as azo dyes have problems such as environmental pollution and unsatisfactory blue light absorption. There are many hybrid orbitals inside blue light conversion agents such as rare earth fluorescent materials, which easily absorb light of other colors, thereby affecting visual effects. There is a small amount of anti-blue light added. Not ideal, adding a large amount of light easily absorbs other colors, resulting in poor visual effects, and adding such a light transfer agent to the adhesive may easily cause poor adhesion and the glue will fall off from the substrate
