Abstract

The invention relates to the technical field of release film preparation and provides a preparation method of an antistatic flame-retardant modified PET / PE composite release film. The method comprises the following steps: modification and preparation of a composite base film; preparation and coating of a release layer coating diluent; compounding and coating of a flame-retardant layer composite flame retardant; and thermocuring and photocuring of the coated base film to obtain the antistatic flame-retardant modified PET / PE composite release film. By adopting the preparation method provided by the invention, the prepared modified PET / PE composite release film effectively improves the rigidity and strength of the release film; due to the steps of thermocuring and photocuring, the performance of the outer flame-retardant layer is more stable; and the release film prepared by the method has excellent mechanical property, good processability and good antistatic and flame-retardant properties.

Description

technical field

[0001] The invention relates to the technical field of release film preparation, in particular to a method for preparing an antistatic and flame-resistant modified PET / PE composite release film. Background technique

[0002] Polyethylene terephthalate (PET) is an important engineering plastic with excellent physical and mechanical properties; polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene, which has excellent low temperature resistance (The lowest operating temperature can reach -100~-70°C), good chemical stability. The modified PET / PE release film is based on PET / PE film, and a layer of silicone oil is coated on the surface of PET / PE film, so it is also called silicone oil film, which makes the surface of PET / PE film smooth, thereby reducing PET. / The surface tension of the PE film makes it have better release force and achieve the effect of release.

[0003] The conventional thickness of the modified PET release film is ...
