Problems solved by technology

[0003] In organic electroluminescent displays, the average lifespan of existing organic light-emitting materials can reach more than 15,000 hours, which can already be applied to actual mass-produced products. However, organic light-emitting materials have a disadvantage: they are prone to failure when exposed to water and oxygen. , if water pollution and erosion can be completely prevented d

Example Embodiment

[0036] The preparation method of the developable UV curable hydrofluoric acid resistant protective glue includes the following steps: according to the mass ratio, the resin, active monomer, photoinitiator, filler, auxiliary agent, and organic pigment are stirred at a temperature lower than 30°C Even if it is uniform, a developable UV curable hydrofluoric acid resistant protective glue is obtained.

[0037] Test the viscosity. If the test result does not meet the set viscosity threshold, adjust the viscosity to the viscosity threshold. The set viscosity threshold is the viscosity range of the prepared developable UV curable hydrofluoric acid resistant protective glue. Viscosity is the main parameter that determines the performance of the developable UV curable hydrofluoric acid resistant protective adhesive. Too much viscosity is not conducive to the coating of the developable UV curable hydrofluoric acid resistant protective adhesive; while the viscosity is too small, resulting in...

Example Embodiment

[0044] Example 1

[0045] In this embodiment, the composition and ratio (mass percentage) of the raw materials of the developable UV curable hydrofluoric acid resistant protective glue are as follows:

[0046] Bisphenol A epoxy acrylic light curing resin 50%, polyether-based urethane acrylate 20%, photoinitiator 3694.5%, dodecafluoroheptyl methacrylate 5%, trimethylolpropane tri(meth)acrylate 5%, pentaerythritol tri(meth)acrylate 5%, filler 8%, auxiliary agent 2% and pigment PR2540.5%, stir and mix evenly.

[0047] The etching resistance of the test scheme was measured according to the above-mentioned etching resistance test method. The thickness of the protective film was 35mm, the etching time was 1.5h, the etching depth was 0.45mm, and the film removal time was 30min.

Example Embodiment

[0048] Example 2

[0049] In this embodiment, the composition and ratio (mass percentage) of the raw materials of the developable UV curable hydrofluoric acid resistant protective glue are as follows:

[0050] Bisphenol A epoxy acrylic light curing resin 22%, PU modified epoxy acrylic resin 22%, aliphatic urethane acrylate 20%, photoinitiator 3696.5%, hexafluorobutyl acrylate 2%, dodecafluoromethacrylate Heptyl ester 3%, trimethylolpropane tri(meth)acrylate 10%, filler 9%, auxiliaries 5% and pigment PR2540.5% are stirred and mixed evenly.

[0051] The etching resistance of the test protocol was measured according to the above-mentioned etching resistance test method. The thickness of the protective film was 60mm, the etching time was 3h, the etching depth was 1.10mm, and the film removal time was 75min.

Abstract

The invention discloses a developable UV cured hydrofluoric acid-resistant protection glue, which comprises the following components by mass percentage: 15-75% of main resin, 10-55% of auxiliary resin and 6-30% of active monomer. The developable UV cured hydrofluoric acid-resistant protection glue has excellent gluing capability by comparing with the hydrofluoric acid-resistant protection glue in prior art, and has extremely high bonding intensity and excellent hydrofluoric acid-resistant etching performance.

Description

technical field [0001] The invention relates to a developable UV-curable hydrofluoric acid-resistant protective adhesive, in particular to an adhesive used for etching a groove with a flat bottom and capable of holding a desiccant on a glass cover plate of an organic electroluminescent display (OLED) Developable UV curable hydrofluoric acid resistant protective adhesive. Background technique [0002] OLED, Organic Light Emitting Diode (Organic Light Emitting Diode), also known as Organic Electro Luminescence Display (OELD), is a new generation of flat-panel display technology after TFT-LCD (Thin Film Transistor Liquid Crystal Display). OLED is different from the traditional LCD display method. It is a self-luminous material without a backlight. It uses a very thin organic material coating and a glass substrate. When an electric current passes, these organic materials will emit light. In addition, OLED has the advantages of simple structure, high contrast, thin thickness, wi...
