preparation example Construction

[0034] The preparation method of the water-based glue remover applied to the OCA optical glue on the mobile phone cover comprises the following steps:

[0035] Step 1. Divide the solubilizer in the formulated amount three times and mix it evenly with the methyl salicylate in the formulated amount as component A;

[0036] Step 2, put the pH regulator, softener, and penetrant into water according to the proportion and stir to dissolve, as component B;

[0037] Step 3. Slowly add component A to component B at a rotation speed of 150-350r / min. After the addition, reduce the rotation speed to 100r / min, continue stirring for 30min, and add liquid paraffin according to the proportion after standing still.

Embodiment 1

[0039] This embodiment provides a water-based glue remover applied to OCA optical glue on the mobile phone cover, including the following components in mass percentage: 10% of methyl salicylate, 45% of butyl glycol ether, 0.3% of LF305, and triethanolamine 3%, liquid paraffin 1.5%, citric acid 0.8%, water 39.4%.

[0040] The preparation method of the water-based glue remover applied to the OCA optical glue on the cover plate of the mobile phone is: the ethylene glycol butyl ether of the formula is divided into three times and the methyl salicylate of the formula is uniformly mixed as component A; Put citric acid, triethanolamine, and LF305 into water according to the ratio and stir to dissolve, as component B; then slowly add component A to component B at a speed of 150-350r / min, after adding, reduce the speed to 100r / min, continue to stir for 30min, after standing still, add liquid paraffin according to the proportion.

Embodiment 2

[0042] This embodiment provides a water-based glue remover applied to OCA optical glue on the mobile phone cover, including the following components in mass percentage: 10% of methyl salicylate, 25% of ethylene glycol butyl ether, and 20% of ethylene glycol ether , LF3050.3%, triisopropanolamine 3%, liquid paraffin 1.5%, citric acid 0.5%, water 39.6%.

[0043] The preparation method of the water-based glue remover applied to the OCA optical glue on the cover plate of the mobile phone is: the ethylene glycol butyl ether and ethylene glycol ethyl ether of the formula amount are evenly mixed three times with the methyl salicylate of the formula amount, as Component A; in addition, put citric acid, triisopropanolamine, and LF305 into water and stir to dissolve according to the proportion, as component B; then slowly add component A to component B at a speed of 150-350r / min, After adding, reduce the rotation speed to 100r / min, continue to stir for 30min, and add liquid paraffin acc...

Abstract

The invention provides a water-based adhesive remover applied to an OCA on a mobile phone cover plate. The water-based adhesive remover is prepared from the following components in percentage by mass: 10 to 25 percent of methyl salicylate, 35 to 55 percent of solubilizer, 0.2 to 0.8 percent of penetrant, 3 to 5 percent of softener, 1.5 to 3 percent of odor masking agent, 0.2 to 1.5 percent of PH value regulator and 10 to 40 percent of water; and the water-based adhesive remover is neutral. According to the water-based adhesive remover applied to the OCA on the mobile phone cover plate and the preparation method of the water-based adhesive remover of the invention, the methyl salicylate, the solubilizer, the penetrant, the softener, the odor masking agent and the pH regulator are scientifically proportioned, so that the functions of all the components are combined and cooperated, the OCA can be easily removed, the adhesive removal efficiency is high, the effect is good, the adhesive can be completely removed by 100%, no residue exists, the corrosion damage to black oil on the cover plate is avoided, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of glue remover, in particular to a water-based glue remover applied to OCA optical glue on a cover plate of a mobile phone and a preparation method thereof. Background technique [0002] OCA optical adhesive is one of the important raw materials for touch screens. It is made of optical acrylic adhesive without substrate, and then laminated with a layer of release film on the upper and lower layers. It is a double-sided adhesive tape without substrate material. It is the best adhesive for touch screen. Its advantages are high clarity, high light transmittance (full light transmittance>99%), high adhesion, high weather resistance, water resistance, high temperature resistance, UV resistance, controlled thickness, can provide uniform spacing, long There will be no problems of yellowing (yellowing), peeling and deterioration over time. However, in the pressing process of the mobile phone cover, there are o...
