Abstract

The invention discloses a metal hybrid fluorosilicon ultra-light release agent, which is prepared from the following components in parts by weight: 100 parts by weight of fluorosilicon block silicone oil, 1-20 parts of cross-linking agent, 1,000-10,000 parts of solvent, and 10-600 ppm of Pt catalyst. ; and its preparation method. In order to improve the bonding force between the fluorosilicon release agent and the substrate, improve the heat resistance, reduce the release force, and improve the residual adhesion, the invention introduces metal titanium atoms into the fluorosilicon release agent, and significantly improves the release coating. The bonding fastness of the layer to the substrate greatly improves the heat resistance. At the same time, the cross-linkable polar group is introduced to form a fast bond between the coating and the substrate, and the residual adhesion is improved.

Description

technical field [0001] The invention relates to the technical field of adhesive coating, in particular to a metal hybrid fluorosilicon ultra-light release agent and a preparation method thereof. Background technique [0002] The release agent, that is, the release agent, is to prevent the formed composite product from sticking to the mold, and a type of isolation film is applied between the product and the mold so that the product can be easily released from the mold while ensuring the surface quality of the product And mold intact. In the field of pressure-sensitive adhesives, the release agent plays the role of blocking the adhesion between the adhesive layer and the back of the substrate. [0003] At present, for silicone pressure-sensitive adhesives, fluorosilicon release agents must be used to achieve phase separation between silicone pressure-sensitive adhesives and fluorosilicon coatings, thereby achieving a release effect. However, the traditional fluorosilicone re...
