Abstract

The invention provides a photoluminescent adhesive composition and a photoluminescent adhesive. The photoluminescent adhesive composition is prepared from a solvent adhesive, an organic photoluminescent material, a dispersant, a curing agent and a solvent, wherein the solvent adhesive is an acrylate solvent adhesive with a benzene ring or a polyurethane solvent adhesive with a benzene ring; the amount of the organic photoluminescent material used is 0.1% to 5% of the weight of the solvent adhesive; the amount of the dispersant used is 0.1% to 5% of the weight of the solvent adhesive; the amount of the curing agent used is 0.1% to 10% of the weight of the solvent adhesive; and the amount of the solvent used is 5 to 50 times the weight of the solvent adhesive. In the role of the dispersant,an organic luminescent material and the solvent adhesive of the system have better dispersibility; at the same time, by controlling the amount of each component, the molecular weight of a polymer formed by subsequent curing of the composition is adjusted to ensure better curing and film-forming performance of the composition, so as to ensure the optical properties such as light transmittance and haze of a photoluminescent device with the composition. In addition, the cost is greatly reduced by virtue of the organic photoluminescent material.

Description

technical field [0001] The invention relates to the field of luminescent materials and devices, in particular to a photoluminescent adhesive composition and a photoluminescent adhesive. Background technique [0002] With the development of display technology, display products are changing with each passing day. According to the different display devices used, there are liquid crystal, plasma, LED and projection, etc. Projection is mainly used in conference rooms, home theaters, exhibitions, exhibition halls, technology exhibitions and tourist attractions. . [0003] The above-mentioned display devices all need to use photoluminescent devices, and these devices have complex structures, low light transmittance (such as the liquid crystal display made by eliminating the backlight also only has 15% transmittance), relatively expensive price, low luminous efficiency, The device is sensitive to external conditions such as light, heat and oxygen. [0004] In addition, the existin...
