Abstract

The invention relates to a thermocuring peelable blue gel and a preparation method thereof. The thermocuring peelable blue gel is prepared from the following raw materials by weight: 5-20 parts of polyester modified acrylic resin, 15-80 parts of polyvinyl chloride paste resin, 0.1-2 parts of liquid epoxy resin, 30-50 parts of a plasticizer, 0.05-0.1 part of a heat stabilizer, 0.01-0.1 part of a curing agent, 10-70 parts of an organic solvent and 0.1-0.2 part of pigment. The preparation method comprises the following steps of: mixing the raw materials in parts by weight, stirring and dispersing the materials uniformly, conducting grinding until the fineness is less than 50 microns, and performing filtering to obtain the thermocuring peelable blue gel. The thermocuring peelable blue gel is good in film forming property, high in film strength, good in CNC resistance, easy to peel and free of residue after film stripping, and can be applied to temporary protection of touch screen glass.

Description

technical field [0001] The technical field of peelable glue of the present invention, in particular relates to a heat-cured peelable blue glue and a preparation method thereof. The heat-cured peelable blue glue is mainly used for temporary protection in the CNC process of a touch screen. Background technique [0002] With the rapid development of information technology and flat display technology, the application of touch screens is becoming more and more common. As large as information query systems in public places, as small as personal computers, tablet computers, and mobile phones, touch screens are closely related to our lives. [0003] In the CNC process of the touch screen, in order to protect the touch screen from mechanical scratches, wear, pollution, corrosion, etc., it is necessary to use peelable blue glue to temporarily protect the touch screen glass many times. Peelable blue glue is mainly used on the transparent conductive glass in the touch screen and the IT...
