Abstract

The invention provides high-shielding flame-retardant FPI release paper and a preparation method thereof. The high-shielding flame-retardant release paper comprises base paper, shielding layers, coating layers and release agent layers, wherein the base paper is white kraft paper; two sides of the white kraftpaper are coated with the shielding layers; the coating layers uniformly coat the corresponding shielding layers; the release agent layers are organic silicon layers and uniformly coat the corresponding coating layers. The shielding layers of the release paper provided by the invention have good shielding performance and are well applied in the electric field; the coating layers of the release paper have a flame retardant function, protect the integral release paper, and have a high-temperature resisting effect; by using the coating layers, the phenomena of high-temperature melting and burning are prevented, and the safety of production is improved; meanwhile, the release paper prepared by the preparation method provided by the invention has a dense structure and does not absorb water, so that the safety of FPI is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of release paper, in particular to a high-shielding, flame-retardant FPI release paper and a preparation method thereof. Background technique [0002] Release paper, also known as release paper and anti-adhesive paper, is mainly used to stick the adhesive layer on the surface of the tape to protect the surface of the tape. The existing release paper is generally coated with a film layer (the material used is mainly polyethylene) on the surface of the bottom paper layer of the release paper, and then coated with a layer of release agent on the surface of the film layer ( The material used is mainly silicone oil) to obtain release paper. Release paper has a wide range of applications, such as electronics, medical and other fields. The existing release paper has single characteristics, and the use of release paper is limited due to its special working environment. Such as external electromagnetic signal shiel...
