[0054] Method for preparing adhesive composition

[0055] The adhesive composition of the present invention can be prepared by putting materials into a stirring tank according to the ratio of raw materials of each adhesive composition as described above, and stirring according to a certain speed and time. The preparation process is generally carried out at normal temperature and pressure, and requires protection from light and constant temperature. Taking the following example 1 as an example, in the first step, the raw materials (meth)acrylate oligomer CN8004, isobornyl (meth)acrylate, and lauryl (meth)acrylate are sampled and weighed and put into the kettle For pre-stirring, the stirring speed is set at about 50 to about 80 rpm, and the stirring time is about 60 minutes; in the second step, GENIOSIL STP-E10 is sampled and weighed and put into the kettle for pre-stirring, and the stirring speed is set at about 100 to about 120rpm, stirring time is about 20min. The third s...

Abstract

The invention provides an adhesive composition. Based on the total weight of the adhesive composition, the adhesive composition comprises the following components in percentage by weight: (A), about 20wt%-60wt% of silane-capped oligomer, (B), about 20wt%-60wt% of (methyl) acrylic ester monomer, (C), about 0-50wt% of (methyl) acrylic ester oligomer, (D), about 0.5wt%-5wt% of a photoinitiator and (E), about 0-0.5wt% of a metal organic compound catalyst. The adhesive composition is ultraviolet-curable and moisture-curable. The invention further provides a method using the adhesive composition, wherein the method comprises the following steps of: (i) coating the adhesive to the to-be-adhered base materials; (ii), laminating / stacking the to-be-adhered base materials to form a part; (iii), radiating the part by ultraviolet light; and (iv), placing the part under the room temperature. Besides, the invention further relates to the use of the adhesive composition in a display screen, a touch screen and an optical apparatus.

Description

technical field [0001] The present invention relates to UV and moisture curable adhesive compositions, methods of using said adhesive compositions and their use in display screens, touch screens and optical devices. Background technique [0002] Currently, in many fields of the electronics industry, such as the manufacture of LCD touch screens, adhesives are commonly used to bond various substrates and components. The more common adhesives used for this purpose are UV curable adhesives. However, complex and special designs and opaque components such as ceramics and metals create light-transmitting areas and opaque dark areas in devices such as display screens and touch screens. Conventional UV-curable adhesives cannot meet the needs of practical production applications due to the inability to effectively reach the opaque dark areas of the device when using UV radiation. [0003] For this problem, existing research attempts to solve it by using adhesives with UV-curable and...
