Abstract

The invention belongs to the field of organosilicon chemistry and discloses a solvent-based paper release agent with low peeling force and a preparation method thereof. The solvent-based paper release agent with low peeling force is composed of the following components by weight: component A: 30-100 parts; component B: 4-30 parts; inhibitor 0.5-1.5 parts; catalyst 0.5-1 parts; solvent: 500-600 parts. The preparation method includes the following steps: (1) firstly mix the component A, component B and solvent, then add the catalyst and mix and stir evenly; (2) then add the inhibitor, mix and stir evenly, and obtain the low-peeling Strong solvent-based paper release agent. The solvent-based paper release agent of the invention can be quickly cured at a relatively low temperature, has excellent effect, good coating appearance, good bonding force to substrates, low silicon transferability, low peeling force, and a residual adhesion rate as high as 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 low peeling force 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 light peeling, ...
