Problems solved by technology

If the adhesive performance of the protective film is not enough, the acid-resistant film and the ITO (Indium Tin Oxides, indium tin oxide) surface of the OGS glass will not be tightly bonded, and hydrofluoric acid will penetrate into the glass, causing damage to the OGS glass. If the electrostatic voltage in the tear-off process after bonding is too large, it may have a certain adverse effect on the ITO surface of the OGS glass. At the

specific Embodiment approach 1

[0024] The preparation method of the antistatic and acid-resistant protective film for the OGS process of this embodiment is realized through the following steps:

[0025] ① Dissolve 1.0 parts of HDI polyisocyanate crosslinking agent in 20 parts of ethyl acetate and 20 parts of toluene mixed solvent in parts by mass, and pour it into 80 parts of acrylate pressure-sensitive resin after stirring for 5 minutes. After fully stirring, add 0.1 part of anionic antistatic agent, fully stir for 10 minutes, and obtain an antistatic acid-resistant pressure-sensitive adhesive after filtration, and all stirring speeds are 50r / min;

[0026] ② Coat the antistatic and acid-resistant pressure-sensitive adhesive prepared in ① with a dimple coating head on the corona-treated BOPET film with a thickness of 50 μm. The coating speed is 10 m / min, and the maximum temperature of the oven is 80 ° C. Finally, Laminated with BOPET release film to obtain antistatic and acid-resistant protective film for O...

Embodiment 2

[0032] The difference between this embodiment and Example 1 is that in step ①, 3.0 parts of HDI-type polyisocyanate crosslinking agent is dissolved in a mixed solvent of 50 parts of ethyl acetate and 10 parts of toluene, and after fully stirring, it is poured into 90 parts of acrylic acid In the ester resin, add 1.0 parts of anionic antistatic agent after fully stirring. Other steps and parameters are the same as in Embodiment 1.

Embodiment 3

[0034] The difference between this embodiment and Example 1 is that 5.0 parts of HDI type polyisocyanate crosslinking agent is dissolved in 100 parts of ethyl acetate solvent, fully stirred and poured into 100 parts of acrylate resin, and then 2.0 parts are added after fully stirred Polymer type antistatic agent. Other steps and parameters are the same as in Embodiment 1.

Abstract

The invention relates to an acid-proofing antistatic protective film for manufacture procedure of OGS (one glass solution). The acid-proofing antistatic protective film is characterized in that the acid-proofing antistatic protective film sequentially comprises a base material, an acid-proofing antistatic adhesive layer and a release film from bottom to top, or sequentially comprises a base material, the acid-proofing antistatic adhesive layer and a release paper. A production method of the acid-proofing antistatic protective film comprises the steps of dissolving 0.1-5 parts of polyisocyanate cross-linking agent into mixed solvent of 10-100 parts of ethyl acetate, 0-20 parts of methylbenzene and 0-30 parts of butanone, fully mixing for 5-15min, adding 80-100 parts of pressure-sensitive adhesive resin, 0.1-2 parts of antistatic agent and 0-1 part of inhibitor, mixing and stirring at 50-800r/min for 10-30min, filtering to obtain acid-proofing antistatic pressure-sensitive adhesive, uniformly coating the acid-proofing antistatic pressure-sensitive adhesive onto the surface of the base material after corona treatment, baking and curing at 80-160 DEG C, and laminating with the release film or the release paper to obtain the acid-proofing antistatic protective film for manufacture procedure of OGS (one glass solution). The acid-proofing antistatic protective film has good glueability and good stability, has no adhesive residue after long-time gluing, and has excellent anti-static function.

Description

technical field [0001] The invention relates to a protective film for the OGS process, more specifically to an antistatic and acid-resistant protective film for the OGS process for chemical secondary strengthening of the OGS glass. Background technique [0002] With the continuous advancement of technology, the competition of consumer touch products is becoming more and more fierce. All manufacturers are scrambling to seize the opportunity in product design and manufacturing in order to obtain the high gross profit of new products during the honeymoon period. Therefore, OGS (One Glass Solution, single glass touch solution or single glass touch technology) has gradually taken shape at the end of last year to replace G (Glass, glass) / G (Glass, glass) market position. The structure of OGS products is simple, the technical level threshold is not high, and it is a piece of glass substrate less in the overall structure, which reduces weight and product thickness, reduces costs...
