Photosensitive coating resin of auxiliary plates for drilling and application thereof

Abstract

A photosensitive resin composition and auxiliary plates for drilling are introduced. The auxiliary plates are made by coating the photosensitive resin composition on aluminum foil and photocuring the coated resin to make the resin bonded on the aluminum foil. The resin composition comprises a first polymer formed by the reaction of 1,2,4,5-pyromellitic dianhydride and polyetheramine; and a second polymer formed by the reaction of polyetheramine and vinyl chloride, wherein the second polymer is a photosensitive polymer. The novel resin composition provided by the present invention can be coated on drilling auxiliary plates. When the drilling auxiliary plates coated with the resin composition are used in a drilling process, it can avoid the coated resin being cracked due to the heat caused by friction of high speed drilling, so it can further enhance the stability, accuracy, and precision of drilling.
