Technical Field

The invention relates to release paper and a preparation method thereof, in particular to flame-retardant release paper and a preparation method thereof.

Background

Release paper is also called release paper and is widely used in life and process of people, the release paper is generally divided into a double-sided release type structure and a single-sided release type structure, the structure has a two-layer structure or a three-layer structure, the two-layer structure is, for example, a glassine base paper coated with a release agent to prepare release paper, the three-layer structure is, for example, a PEK laminating paper coated with the release agent to prepare PEK release paper, and therefore the release paper is prepared by coating the release agent on a base paper of the release paper. The existing release paper such as glassine release paper and PEK release paper do not have flame retardant property.
