Problems solved by technology

However, the adhesive layer with a thinner thickness usually has the disadvantage of low bonding strength, and it cannot maintain the stickiness under the condition of large temperature difference, and it is easy to peel off the adhesive from the adherend
Therefore, most of the existing optical adhesives cannot take into account the bonding strength on the premise of ensuring good optical properties and heat resistance.

Abstract

The invention relates to the field of optical tapes, in particular to a high-viscosity optical film tape and a manufacturing process thereof. The high-viscosity optical film tape comprises a light release film layer, an optical adhesive layer and a heavy release film layer which are arranged from top to down sequentially, wherein the optical adhesive layer is made of an adhesive, and the adhesive is,prepared from the following components in parts by weight, 30-50 parts of butyl methacrylate, 15-30 parts of ethyl acrylate, 10-20 parts of trimethylopropane trimethacrylate, 3-8 parts of crylic acid, 2-5 parts of melamine formaldehyde resin, 1-4 parts of triethylene tetramine, 1-5 parts of nano silicon dioxide and 0.5-2 parts of initiator. The components of the adhesives coordinate with one other, so that the prepared optical film tape has the advantages of high light transmission, high temperature resistance and high adhesive strength when used for bonding; in addition, the manufacturing process is simple, the production efficiency is high, the product quality is stable, and the overall performance of the high-viscosity optical film tape is excellent.

Description

technical field [0001] The invention relates to the technical field of optical tapes, in particular to a high-viscosity optical film tape and a manufacturing process thereof. Background technique [0002] With the progress of society and the development of science and technology, consumers have put forward higher requirements for the comprehensive performance of electronic products or other products, and the appearance of products is also particularly important. Optical film tape OCA optical adhesive is often used to glue transparent optical components. The common production method is to make optical adhesive without base material, and then attach a layer of release film to the upper and lower bottom layers to make double-sided bonding. adhesive tape. The optical adhesive layer made of optical glue is the core part of the optical film tape. The performance of the optical adhesive layer directly affects the use effect of the optical film tape. In the production process of e...
