Problems solved by technology

[0003] At present, the substrates suitable for solvent-free release silicone oil include paper substrates such as glassine paper and coated paper PEK. If solvent-free release silicone oil is applied to polyester film PET film coated with silicon, serious problems will occur. The phenomenon that the release silicone oil coating falls off, resulting in difficult or even non-release consequences

Abstract

The present invention relates to release silicone oil, in particular to a solvent-free release silicone oil suitable for PET films and a preparation method thereof. The solvent-free release silicone oil includes the following components: polyorganosiloxane containing acryloyloxypropyl alkanes, vinyl-terminated phenyl silicone oils, acetylenic alcohols, cross-linking agents, castor catalysts. In the present invention, the polyorganosiloxane containing acryloxypropyl group is used as the main agent of the release silicone oil, which can greatly increase the adhesion of the release silicone oil to the PET film, and the prepared release silicone oil has no desiliconization phenomenon after application , has a very light peeling force, and the adhesive layer still has a high adhesion after peeling off the release silicone oil coating.

Description

A kind of solvent-free release silicone oil suitable for PET film and preparation method thereof technical field The present invention relates to release type silicone oil, relate in particular to a kind of solvent-free release type silicone oil suitable for PET film coating silicon and preparation thereof. preparation method. Background technique Release type silicone oil is mainly divided into solvent type release type silicone oil and solvent-free type release type silicone oil. It contains solvent, and a large amount of solvent needs to be added during use, which has great harm to the environment and personnel, and will be gradually removed. Eliminate. The solvent-free release silicone oil product itself is non-toxic and non-polluting, and does not require the use of solvents during use, which is non-polluting to the environment. Contaminated, non-toxic to personnel. At present, the substrate that solvent-free release silicone oil is adapted to has paper subst...
