Embodiment

[0034] Embodiment: the preparation of release film

[0035] The terminal hydroxyl-containing vinyl silicone oil of the present invention has a structural formula as follows:

[0036]

[0037] Wherein, n=1-10, m=0-6.

[0038] Substrate: Glassine paper.

[0039] Release agent components: the main agent is vinyl silicone oil with a viscosity of 180cps; the crosslinking agent is hydrogen-containing silicone oil with a viscosity of 100cps, and the vinyl silicone oil with hydroxyl groups at the end of the present invention has a viscosity of 40cps; the catalyst is a platinum catalyst with a viscosity of 190cps; inhibitors are ethynylcyclohexanol and 2-phenyl-3-butyne-ethanol.

[0040] Mix the above-mentioned release agent components: main agent, cross-linking agent, inhibitor, release force regulator, and catalyst with mechanical stirring, fully stir evenly, and the stirring time is about 20 to 30 minutes; coat the stirred release agent On the surface of the substrate, when co...

Abstract

The invention belongs to the technical field of release force regulators, discloses an application of vinyl silicone oil containing hydroxyl groups at terminal as a release force regulator to preparation of a release agent, the release agent and a release film and particularly provides an application to preparation of an addition type organosilicon release agent. According to the application of the vinyl silicone oil containing the hydroxyl groups at the terminal as the release force regulator to preparation of the release agent, the structural formula of the vinyl silicone oil containing the hydroxyl groups at the terminal is shown in the description, wherein n and m represent constitutional repeating units, n ranges from 1 to 10, and m ranges from 0 to 6. The vinyl silicone oil containing the hydroxyl groups as the regulator contains double functional groups, namely, the hydroxyl groups and vinyl groups, thereby having double functions when applied to the release agent, substrate bonding firmness is enhanced by the hydroxyl groups, surface tension of the material is improved by introduction of the hydroxyl groups, the vinyl groups participate in hydrosilylation, compatibility with the release agent is enhanced, the release film with remarkably improved release force can be obtained, and the higher the content of the vinyl silicone oil is, the higher the release force of the release film is.

Description

technical field [0001] The invention belongs to the technical field of release force regulators, in particular to the application of vinyl silicone oil containing hydroxyl groups at the terminal as a release force regulator in the preparation of release agents and release agents and release films, especially the preparation of addition-type organic Application in silicon release agent. Background technique [0002] Addition-type silicone release agent refers to the addition reaction of vinyl-containing organopolysiloxane and Si-H bond-containing organopolysiloxane under the catalysis of Group VIII transition metal compounds (such as Pt, Ni), etc. A substance that can reduce or eliminate the adhesion on the surface and separate two surfaces that are difficult to separate or cannot be separated. It has a wide range of applications and an important position in organosilicon chemistry. It can be widely used in industries such as pressure-sensitive tape, self-adhesive label, med...
