Problems solved by technology

[0004] At present, some specially designed capacitive touch screens have large FPC lines on the conductive glass. Because the FPC itself is impermeable to UV light, the LOCA (liquid optical transparent adhesive) glue under the FPC is often blocked by the FPC. role, but can not absorb UV light, which eventually leads to LOCA (liquid optically clear adhesive) not curing, or curing is not complete

Abstract

The invention provides a synthesizing method for multi-curing available optical resin. The method comprises the following steps: adding 80-110g of HDI tripolymer, 5-10g of 3-ethyl-3-(hydroxymethyl) oxacyclobutane, 4-10g of hydroxyl acrylate, 0.1g of polymerization inhibitor 4-methoxyphenol and 0.01g of catalyst dibutyltin dilaurate into a three-necked flask with a thermometer, and heating to 65 DEG C; controlling the temperature to be 60-75 DEG C, reacting for 2-3 hours, analyzing NCO group with an infrared infrared spectrometer; and stopping the heat reaction when the NCO peak does not change so as to obtain the multi-cured functional resin capable of free radical+cation+moisture reaction.

Description

technical field [0001] The invention relates to a multi-curable optical resin and a synthesis method thereof. The optical resin has the multi-cure function of free radical + cation + moisture reaction, can be used in liquid optical transparent glue, and belongs to the field of light-curable materials. Background technique [0002] With the continuous upgrading of flat panel display technology, touch screen as a new technology has been continuously applied to mobile phones, computers and other products, especially driven by the tide of mobile Internet, more and more flat panel display products use capacitive touch screen control technology. Capacitive touch technology has advantages over traditional resistive touch technology in terms of multi-touch design, gesture recognition, response speed, sensitivity, durability, and optical characteristics. According to the current production process, capacitive touch screens need to use an adhesive material to assemble each layer of t...
