Abstract

The invention provides an organic silica gel optical adhesive film. The organic silica gel optical adhesive film comprises an upper-layer release film and a lower-layer release film, wherein an organic silica gel layer is also arranged between the upper-layer release film and the lower-layer release film, and the organic silica gel layer comprises transparent organic silica gel adhesive and is obtained by mixing a component A with a component B in mass ratio of 1:1. The organic silica gel optical adhesive film has the advantages that organic silica gel is clamped between two release films, the silica gel can not be hardened under normal temperature condition, so that only one release film is firstly uncovered and bonded on a base plate to be laminated when the organic silica gel optical adhesive film is used, then the other release film is uncovered, an optical element to be laminated is pasted, thereby being convenient; meanwhile, the organic silica gel optical adhesive film can be cut at will and can not be limited by a mould and mechanical equipment, usable range is more broad, and production cost of an optical transparent element can be effectively reduced.

Description

technical field [0001] The invention relates to an adhesive film used for bonding optical devices, in particular to a silicone gel optical adhesive film and a production process for the organic silicon gel optical adhesive film. Background technique [0002] In the production process of many optically transparent components, glue coating and bonding processes are usually used, such as bonding touch screens and display screens. The existing bonding process is usually to apply glue on a substrate first, and then use a squeegee to scrape the glue evenly after the glue is applied, and then paste another optical plate on the substrate. The current bonding process is all completed in the form of gluing, which requires more equipment and higher process requirements, which will increase production. In response to this situation, there are currently some optical adhesive films on the market, which can be used to quickly bond optical devices. When the glue on the current optical adhe...
