Combined shading adhesive and manufacturing technology thereof

Abstract

The invention discloses a combined shading adhesive and a manufacturing technology thereof. The combined shading adhesive comprises an adhesive base layer, a release paper and a waterproof layer, therelease paper is adhered to the bottom of the adhesive base layer, a filtering layer is arranged at the top of the adhesive base layer, a reinforced composite layer is arranged at the top of the filtering layer, a wear-resistant layer is arranged at the top of the reinforced composite layer, and the waterproof layer is uniformly distributed on the outer side of the combined shading adhesive. A PCfilm is used as the adhesive base layer, and has flame-retardant and insulating effects, a PET film is used as the wear-resistant layer to reduce the wearing of the shading adhesive, a filtering layeris composed of a magenta filtering film, a yellow filtering film and a cyan filtering film, the three-primary-color filtering films are light-transmitting and overlaid to be black to cooperate carbonblack and ball clay which are uniformly distributed in the reinforced composite layer to absorb lights and isolate heat energy propagation, so that the shading effect of the shading adhesive is greatly improved, and the shading adhesive can effectively insulate heat to prevent heating ageing, thereby the service life of the shading adhesive is prolonged; and the waterproof layer avoids water stain erosion, so the use safety of the shading adhesive is improved.

Description

technical field [0001] The invention relates to the technical field of shading glue production, in particular to a combined shading glue and a manufacturing process thereof. Background technique [0002] Mobile phone liquid crystal displays mainly use light-emitting diodes (LEDs) as backlight sources. Among them, light-emitting diodes are a kind of active light emitters. sheet, glass substrate, and horizontal polarizer, and then the screen output can be formed, thereby realizing the display of rich-color images on the mobile phone LCD. However, in the edge area of ​​the display, the light source is easily scattered due to the large viewing angle, and the light efficiency at the edge of the display becomes low, resulting in a dim picture in the edge area. In order to solve the above situation and concentrate the polarized light source at the edge, a layer of light-shielding adhesive film, that is, light-shielding tape, is usually pasted on the outer frame of the display scre...

AI Technical Summary

Problems solved by technology

[0003] At present, when it is actually used, it is exposed to the light source, and it is easy to age and break after long-term use, the shading efficiency is reduced, the temperature resistance is not good, and there are potential safety hazards
