Problems solved by technology

[0004] However, the peelable blue glue currently on the market generally has the defect that the tensile strength of the protective film body after film formation is small, and glue breakage often occurs during the peeling process, and there will be residual glue during peeling, which needs to be wiped with a solvent. Not only will it consume a lot of labor costs, but also the efficiency is very low, which will affect the product delivery time

Abstract

The invention discloses residual glue-free peelable blue glue after peeling and a preparation method therefor. The blue glue comprises the following components in parts by weight: 25-35 parts of inyl chloride-vinyl acetate resin, 20-30 parts of modified epoxy resin, 8-18 parts of n-butyl stearate, 5-12 parts of silicon dioxide, 2-8 parts of a plasticizer, 3-9 parts of a thixotropic agent, 1-5 parts of a pigment, 5-15 parts of nano filler and 4-10 parts of a defoaming agent. According to the residual glue-free peelable blue glue after peeling prepared by the preparation method disclosed by the invention, the tensile strength of a film after curing is high; the film is not worn if being peeled; the blue glue can be easily peeled from the surface of an adherend; and the peeled adherend is free of residual glue on the surface. The blue glue disclosed by the invention is free of organic solvents and free of solvent volatilization during curing, is environmental-friendly, and is simple in preparation process, low in production cost and easy to produce in a large scale.

Description

technical field [0001] The invention relates to the technical field of peelable glue, in particular to a peelable blue glue without residual glue after peeling and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of information technology and flat-panel display technology, the application of touch screens has become more and more common. From information query systems in public places to personal computers, tablet computers, and mobile phones, touch screens are closely related to our lives. The technology of touch-screen computers and mobile phones has also been extensively improved, and the materials used to manufacture touch screens have also been more in-depth research. During the production process of the touch screen, the glass of the touch screen needs to be temporarily protected many times by peelable blue glue. [0003] After the peelable blue glue is baked into a film, it can prevent the material from being pol...
