Abstract

The invention discloses UV-curing light guide adhesive and a preparation method thereof; the UV-curing light guide adhesive comprises a photoinitiator, a monomer, polybutadiene dimethacrylate, aliphatic polyurethane acrylate, a rheological agent, a leveling agent, a dispersant, a coupling agent, a defoaming agent, and light guide powder; the preparation method comprises the steps of first, mixing well a photo-curing monomer, polybutadiene dimethacrylate and a coupling agent; second, adding aliphatic polyurethane acrylate, a leveling agent, a dispersant, a defoaming agent and a photo-curing agent, and mixing well; third, adding light guide powder, and mixing well; fourth, adding a rheological agent, and mixing well to obtain a finished product; the prepared UV-curing light guide adhesive has excellent advantages of excellent yellowing resistance, peel strength, impact resistance, high luminance, uniformity and the like; the UV-curing light guide adhesive is applied to the surface of reflecting film by means of printing, roll coating, brush coating, and curtaining and is cured by UV irradiation, the technique omits the procedure of manufacturing a light guide plate, production efficiency is improved, and production cost is lowered.

Description

technical field [0001] The invention relates to a functional adhesive, in particular to a UV light curing light guide adhesive used in a liquid crystal display backlight module and a preparation method thereof. Background technique [0002] With the continuous improvement of high-brightness LED point light sources, the design of edge-lit LED line light sources also promotes the development of liquid crystal displays such as LCDs in the direction of thinness and lightness. Liquid crystal displays usually include liquid crystal panels and backlight modules, etc. It is composed of light guide plate, emission plate and light source. [0003] The light guide plate materials mainly include optical acrylic, polycarbonate, styrene copolymer, and cycloolefin polymer. The optical acrylic is used as the base material, and a luminous body is installed on the side. The high light conductivity of the light spot makes the light passing through the light guide plate irradiate each light gu...
