Embodiment 1

[0022] (1) Add 29.1g (0.05mol) AEO to a three-neck flask equipped with a stirrer, thermometer and reflux condenser, heat to 65°C under stirring, slowly add 2.4g (0.06mol) NaOH dropwise (add within 0.5h End) in the three-neck flask, after it is completely dissolved, add 5.9g (0.06mol) MAH dropwise, after dissolving, slowly add 2.4g (0.06mol) NaOH dropwise, and continue the reaction for 4 hours, and a light yellow to orange-red turbid Viscous liquid promptly obtains the organic carboxylic acid nonionic surfactant of the present embodiment.

[0023] (2) Add 60 parts by weight of dichloromethane and 10 parts by weight of ethanol into the reactor, stir for 5 minutes, then add 5 parts by weight of ethyl acetate, continue stirring, and then add 10 parts by weight of organic carboxylic acids in step (1) non-ionic surfactant, while adding 15 parts by weight of a stable solubilizer solution (including 6 parts by weight of methyl monobutyl ether and 9 parts by weight of ethanol), stirred...

Embodiment 2

[0025] The heterosexual conductive adhesive remover S2 of this example was prepared by the same steps as in Example 1, except that in step (1), the amount of MAH was 8.85 g (0.09 mol).

Embodiment 3

[0027] The heterosexual conductive adhesive remover S3 of this example was prepared by the same steps as in Example 1, the difference is that in step (2), the contents of each component are: 50 parts by weight of dichloromethane, 15 parts by weight of ethanol, acetic acid 5 parts by weight of ethyl ester, 5 parts by weight of organic carboxylic acid nonionic surfactant, and 25 parts by weight of stable solubilizer solution (including 12.5 parts by weight of methyl monobutyl ether and 12.5 parts by weight of ethanol).

Abstract

The invention provides an anisotropic conductive adhesive remover. The anisotropic conductive adhesive remover contains a solvent, a surfactant and a stable solubilizer, wherein the solvent comprises halogenated alkane, ethanol and ethyl acetate, and the stable solubilizer is a butyl ether derivative. The invention also provides a preparation method for the anisotropic conductive adhesive remover. The anisotropic conductive adhesive remover provided by the invention is high in adhesive removing efficiency and short in adhesive removing time.

Description

technical field [0001] The invention relates to a heterosexual conductive adhesive remover and a preparation method thereof. Background technique [0002] In the production process of Liquid Crystal Display (LCD for short) or touch screen (Touch panel), Anisotropic Conductive Film (ACF for short) has been widely used to conduct the screen and chip to realize the display control of the circuit on the screen. However, during the production process, due to the influence of equipment and personnel operations, a large number of defective screens (LCD screens and TP screens) will be produced, which greatly increases production costs and also causes a lot of waste of screens and chips. [0003] In order to recycle defective screen products and reduce production costs, various heterosexual conductive adhesive removers have begun to appear in the prior art, which are used to peel off the chips and substrates of defective screen products, so as to achieve the purpose of recycling. Fo...
