Film transfer technology with silica gel protective film as medium

Abstract

The invention provides a film transfer technology with a silica gel protective film as a medium. A semi-finished product is formed firstly through compounding of high-viscosity foam glue and a silica gel protective film, then the high-viscosity foam glue disengages from the silica gel protective film and is combined with a light film, the high-viscosity foam glue is transferred onto the light film with low viscosity through a production line, and then efficient usage of the high-viscosity foam glue in modern production is ensured. A viscid face of the silica gel protective film is attached to a viscid face of the high-viscosity foam glue, so that it is ensured that an included film corresponding to another viscid face of the high-viscosity foam glue is located on the uppermost layer, the included film is rolled up through a rolling structure, another viscid face of the high-viscosity foam glue is covered with a release film through a compression roller, the semi-finished product is obtained through rolling, then the silica gel protective film on the semi-finished product is rolled up, the corresponding viscid face of the high-viscosity foam glue of the semi-finished product is covered with the light film, and then the product composed of the light film, the high-viscosity foam glue and the release film is obtained through rolling.

Description

technical field [0001] The invention relates to the technical field of membrane transfer, in particular to a membrane transfer process using a silica gel protective film as a medium. Background technique [0002] The self-contained film corresponding to the existing high-viscosity foam glue has a very high viscosity, reaching 35±10g / in, which makes it necessary to overcome a large viscous force in the subsequent use process to peel the foam glue from its self-contained film , since the feeding roller is generally used in modern production, and the machine is used to peel off the self-contained film with a viscosity of 35±10g / in, it is prone to the phenomenon that it cannot be peeled off in time, so it is necessary to remove the high-viscosity foam glue from the self-contained film Up-transfer to less viscous light film, thus ensuring the efficient use of high-viscosity foam in modern production. Contents of the invention [0003] In view of the above problems, the present...
