Abstract

The invention provides a photosensitive adhesive, a preparation method and application thereof, and relates to the technical field of chemical materials. The photosensitive adhesive provided by the invention includes acrylic resin, reactive diluent, high temperature resistant epoxy resin, curing agent, light Initiators, photosensitizers, fillers, pigments and phosphates are resistant to ion migration, thereby avoiding metallization of the photosensitive cover film, and have strong insulating ability, which can greatly extend the service life and save costs. The preparation method of the photosensitive adhesive provided by the invention is easy to operate, has strong practicability, and is suitable for popularization and application. The application of the photosensitive adhesive provided by the present invention in the preparation of a photosensitive cover film, the photosensitive cover film prepared by using the photosensitive adhesive provided by the present invention has the function of ion migration resistance, strong insulating ability, long service life, and can effectively reduce cost.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a photosensitive adhesive and its preparation method and application. Background technique [0002] Flexible Printed Circuit (FPC) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. It has the characteristics of high wiring density, light weight, thin thickness and good bendability. [0003] The photosensitive cover film is a protective insulating film for copper foil in the flexible circuit board industry. However, metal ions migrate to the insulating film section. There are a large number of copper ions on the photosensitive cover film, which will cause metal ionization when the photosensitive cover film is used for a long time phenomenon, thus losing the insulation effect after a period of use, resulting in adverse effects such as short circuit. [0004] Therefore, it is particularly importan...
