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 invention relates to release silicone oil, in particular to solvent-free release silicone oil suitable for a PET (polyethylene terephthalate) film and a preparation method of the solvent-free release silicone oil, and the solvent-free release silicone oil comprises the following components: polyorganosiloxane containing acryloyloxypropyl, vinyl-terminated phenyl silicone oil, alkynol, a cross-linking agent and a Karstedt catalyst. Polyorganosiloxane containing acryloyloxypropyl is used as a main agent of the release silicone oil, so that the adhesive force of the release silicone oil to a PET film can be greatly increased, the prepared release silicone oil has no desilicication phenomenon after being applied and has very light stripping force, and an adhesive layer still has very high adhesive force after being stripped from a release silicone oil coating.

Description

technical field [0001] The invention relates to release-type silicone oil, in particular to a solvent-free release-type silicone oil suitable for coating silicon on PET films and a preparation method thereof. Background technique [0002] The release silicone oil is mainly divided into solvent-type release silicone oil and solvent-free release silicone oil. Since the solvent-type release silicone oil itself contains solvent, a large amount of solvent needs to be added during use, which is harmful to the environment and personnel. was gradually eliminated. The solvent-free release silicone oil product itself is non-toxic and non-polluting, and does not require the use of solvents during use, and has no pollution to the environment and no toxic effects on personnel. [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...
