AI Technical Summary

Problems solved by technology

However, the environmental stability of nano-silver is poor, and traditional OCA is highly corrosive to it, such as causing excessive resistance change rate and affecting touch sensitivity; therefore, it is urgent to develop an OCA optical tape with low corrosion to nano-silver conductive film

Abstract

The invention discloses an optical adhesive composition for a nano metal conducting film and an adhesive film of the optical adhesive composition. The adhesive composition is prepared from the following components in parts by weight: 40-80 parts of a modified acrylic acid derivative polymer, 20-60 parts of an acrylic acid derivative monomer, 0.04-2 parts of a photoinitiator I, 0.01-1 part of a photoinitiator II, and 0-2 parts of a cross-linking agent, the modified acrylic acid derivative polymer is prepared from an organosilicone modified acrylate, and the molecular weight of the modified acrylic acid derivative polymer is 30-80W; the photoinitiator I is selected from one or more than one kind of alpha-hdyroxy-ketone, alpha-amino ketone, benzoin bis-ether and benxoyl formic ester; the photoinitiator II is selected from one or more than one kind of an acyl phosphonic oxide; and the hydroxyl value range of the adhesive composition is controlled in 40-130mgKOH / g. According to the adhesivefilm, adhesive force to a glass / nano-silver conducting film and other materials is good, at the same time, fallibility is good, so the gap between nano-silver and OCA is reduced, water and oxygen areinhibited to enter, and the low-corrosion effect is achieved.

Description

technical field [0001] The invention relates to the technical field of optically transparent adhesives, in particular to an optical adhesive composition for a nano metal conductive film and an adhesive film thereof. Background technique [0002] With the enlargement of the size of touch screen devices and the upgrade of power consumption, how to achieve flexible display, touch sensitivity, and light and thin touch structure while maintaining product battery life and reducing costs has been a matter that those skilled in the art have been working on. Driven by this, a new type of optically functional conductive material "Silver Nanowire" came into being. Conductive films based on silver nanowires endow high electrical conductivity, high optical transmission, excellent flexibility and ductility at a moderate cost, making them ideal replacements for ITO in many applications, especially where thinner and more flexible in the device. However, the environmental stability of nano...
