Abstract

The invention belongs to the field of organosilicon chemistry, and discloses a high residual adhesive rate solvent-type paper isolation agent and a preparation method thereof; the high residual adhesive rate solvent-type paper isolation agent is composed of the following components by weight: 30 parts of a base material, 1-3 parts of hydrogen-containing silicone oil, 70 parts of an organic solvent, 0.5-1.5 parts of an inhibitor and 0.5-1 part of a catalyst. The preparation method comprises the following steps: (1) mixing the base material and the organic solvent, then adding the catalyst, mixing and stirring evenly; (2) then adding the inhibitor, mixing and stirring evenly; and (3) adding the hydrogen-containing silicone oil mixing and stirring evenly to obtain the high residual adhesive rate solvent-type paper isolation agent. The high residual adhesive rate solvent-type paper isolation agent can fast cure at a lower temperature, is excellent in effect, good in appearance of coating, good in substrate adhesion, low in silicon transfer, and low in stripping force, and the residual adhesive rate is up to 85-90%.

Description

technical field [0001] The invention belongs to the field of organosilicon chemistry, and in particular relates to a solvent-based paper release agent with a high residual adhesion rate and a preparation method thereof. Background technique [0002] Paper release agent is mainly used in the production of release paper (also known as anti-adhesive paper), the purpose of which is to make the adhesive and the substrate easily peeled off. Therefore, release paper is widely used to make various pressure-sensitive tapes (paper sheets) and packaging materials for various sticky substances. [0003] Silicone release agents are widely used due to their low toxicity, low surface energy, good wettability with substrates, wide range of temperature applications, and low migration to adhesives. Excellent paper release agents generally need to meet the following requirements: 1. Appropriate peeling force: The peeling force of the release layer to the adhesive layer can be divided into lig...
