Abstract
The invention discloses a high-refractive-index heat-curing silicone adhesive for full lamination of liquid crystal displays, which includes component A and component B, wherein: component A, in parts by weight, includes the following raw material components: 1500- 5-10 parts of 2500mPa.s terminal vinylmethylphenyl vinyl silicone oil; 1-5 parts of 4500-5500mPa.s terminal vinylmethylphenylvinyl silicone oil; 0.02-0.05 parts of platinum catalyst; In parts by weight, it includes the following raw material components: 1-5 parts of 1500-2500mPa.s terminal vinylmethylphenyl vinyl silicone oil; 1-5 parts of 4500-5500mPa.s terminal vinylmethylphenylvinyl silicone oil; 100-300mPa.s terminal hydrogen-containing methyl phenyl hydrogen-containing silicone oil 1-5 parts. The refractive index of the silicone adhesive of the present invention reaches 1.52, which is not much different from the 1.5 of the cover glass, reduces the energy loss caused by the difference in refractive index, and improves the display effect of the liquid crystal display.
Description
technical field [0001] The invention belongs to the technical field of full lamination materials for displays, and in particular relates to a high-refractive-index thermally cured organic silica gel adhesive for full lamination of liquid crystal screen displays and applications thereof. Background technique [0002] The LCD screen of the monitor itself is very fragile, so LCD products need to be attached with a piece of glass outside the LCD screen for protection. There are two main ways to attach the LCD screen to the glass: frame lamination and full lamination. Frame lamination will produce an air layer, which will lead to a decrease in the display clarity of the liquid crystal device, very dazzling under strong direct light conditions, and insensitive touch screens. The ability of the screen itself to resist external damage. Generally, the refractive index of glass is about 1.5, and the adhesives currently used for full lamination on the market are all adhesives with a ...
