Abstract

The invention relates to a release silicone oil product, in particular to solvent-free release silicone oil with medium and heavy release force and a preparation method thereof, and the solvent-free release silicone oil with medium and heavy release force comprises the following components: vinyl silicone oil, alkynol, polysiloxane containing stearoyl propyl, a cross-linking agent and a Karst catalyst. The solvent-free release silicone oil product prepared by the invention is wide in application range to a base material, relatively high in cost performance, good in stability and low in stripping noise, an obvious weight increasing effect can be achieved only by using a very small addition amount, and in addition, the solvent-free release silicone oil product is small in release force attenuation amplitude and high in residual rate after being coated with silicon.

Description

technical field [0001] The invention relates to a release silicone oil product, in particular to a solvent-free release silicone oil with medium and heavy peeling force and a preparation method thereof. Background technique [0002] Release silicone oil can be divided into: solvent release silicone oil, solvent-free silicone oil and emulsion release silicone oil. Solvent-type release silicone oil contains solvent itself, and a large amount of solvent needs to be added during use, which is harmful to the environment and personnel, and will be gradually eliminated; while emulsion-type release silicone oil is currently applicable to a small range, especially for paper. Glassine paper substrates have poor adaptability; solvent-free release silicone oil has wide adaptability, especially for various paper substrates, and the product itself is non-toxic and pollution-free, and does not need to use solvents during use. The environment is non-polluting and non-toxic to personnel, wh...
