Problems solved by technology

Although it can bring about a significant improvement in certain properties, there are deficiencies in the compatibility, degree of embedding, and distribution range of the modifier and PET, which affects the mechanical properties of the PET release film.
The flame retardant effect of the flame retardant in the existing release film is relatively general, unable to meet some specific requirements, and also has poor antistatic performance. Modified PET / PE composite release film with high temperature resistance and flame retardant effect

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 ...
