Abstract
Present invention is disclosed a kind of production method of the cleaning solution before glass thinning, raw material is weak base cleaning agent, 10%~15% sodium hydroxide solution and 0.3%~0.5% citric acid that quality accounting is 3%~5%, and surplus is water；Sodium hydroxide solution and citric acid are separately added into water, are stirred, when solution temperature is warming up to 40 DEG C, weak base cleaning solution is added into solution, obtains mixed solution；Mixed solution is stirred 30 minutes, heats mixed solution, when temperature reaches 45~55 DEG C, cleaning solution is made.By the cleaning solution before the glass thinning of the application by glass substrate be thinned before cleaned, remove the impurity such as organic substance and the residue glue of the oiliness of glass baseplate surface and do not damage glass substrate while there is strong cleaning force, apparent fraction defective of the glass substrate in thinning process after cleaning reduces, and improves production efficiency and product quality.
Description
Technical field
The present invention relates to the technical field of glass thinning cleaning solution, and in particular, to the cleaning solution before a kind of glass thinning
Production method.
Background technology
At present, glass substrate generally carries out reduction processing by the method for chemical etching, in the technique of chemical etching, its
Technical process is generally sealing, is thinned and grinds, and the edge of glass substrate is carried out encapsulation process by sealing, prevents from subsequently losing
Medicament is carved to enter inside glass substrate and influence properties of product.Cure colloid by photocuring during sealing, have glue at this time
Glass baseplate surface is inevitably residued in, produces protrusion, can not be equal if do not removed the link that subsequent etch can be caused to be thinned
Even etching, the process for finally also needing to increase polishing grinding, influences production efficiency, so needing to be cleaned before being thinned.Remove
Residual glue during sealing, glass substrate may have other impurities, it is necessary in thinned work in supplied materials and production and processing
Cleaned before sequence.The glass surface cleaning solution directly bought on the market at present can not clean up the impurity of glass surface,
Follow-up production link is influenced, so as to influence the yield of product.
The content of the invention
In view of the deficiencies of the prior art, the production method of the cleaning solution before a kind of glass thinning of present invention offer.
The production method of cleaning solution before a kind of glass thinning disclosed by the invention, comprises the following steps：
Prepare weak base cleaning agent, 10%~15% sodium hydroxide solution of raw material, including quality accounting for 3%~5%
And 0.3%~0.5% citric acid, surplus is water；
Sodium hydroxide solution and citric acid are separately added into water, are stirred, when solution temperature is warming up to 40 DEG C, to
Weak base cleaning solution is added in solution, obtains mixed solution；
Mixed solution is stirred 30 minutes, heats mixed solution, when temperature reaches 45~55 DEG C, cleaning solution is made.
According to an embodiment of the present invention, above-mentioned weak base cleaning agent contains activating agent benzene sulfonic acid sodium salt.
Compared with prior art, the present invention can be obtained including following technique effect：
By the cleaning solution before the glass thinning of the application by glass substrate be thinned before cleaned, remove glass substrate
The impurity such as the organic substance and residue glue of the oiliness on surface do not damage glass substrate while having strong cleaning force, the glass after cleaning
Apparent fraction defective of the substrate in thinning process reduces, and improves production efficiency and product quality.
Embodiment
Multiple embodiments of the application will be disclosed below, as clearly stated, details in many practices will with
Illustrate in the lump in lower narration.It should be appreciated, however, that the details in these practices is not applied to limit the application.That is,
In some embodiments of the application, the details in these practices is non-essential.
In addition, the technical solution between each embodiment can be combined with each other, but must be with ordinary skill
Personnel can be implemented as basis, and this technical side is will be understood that when the combination appearance of technical solution is conflicting or can not realize
The combination of case is not present, also not within the protection domain of application claims.
The cleaning solution before the glass thinning of the present invention is described further by the following examples.
Cleaning solution is configured first, and it is 10%~15% to prepare weak base cleaning agent, concentration that quality accounting is 3%~5%
Sodium hydroxide solution and 0.3%~0.5% citric acid and 1200L water, add water in liquid pool, then by sodium hydroxide solution
It is separately added into liquid pool, is stirred with citric acid, neutralization reaction occurs for sodium hydroxide solution and citric acid, releases heat,
The temperature of solution is warming up to 40 DEG C in liquid pool.Weak base cleaning agent is added in liquid pool and is mixed, is stirred 30 minutes, mixing is abundant
Afterwards, by liquid pool heat temperature raising, the temperature in liquid pool is in 45~55 DEG C, that is, cleaning solution is made.Wherein, weak base cleaning agent
Main component be weak base, also containing activating agent benzene sulfonic acid sodium salt.
According to above range, the content and heating-up temperature of each component are adjusted respectively, three groups of cleaning solutions are configured, such as table 1 below, table
2 and table 3 shown in, the constituent content in every group of cleaning solution is adjusted, the glass base for the same model that same provider is provided
Plate is respectively put into each group cleaning solution and is cleaned.Choose the TFT glass of the model C040 of Long Teng Electronics Co., Ltd. production
Substrate is as test sample.After cleaning, the glass substrate after each group is cleaned respectively takes out and carries out chemical etching and is thinned,
Check one by one apparent whether normal or there are the bad phenomenons such as salient point, concave point after each group glass substrate etching.
Table 1
Table 2
Table 3
It was found from the data in table, glass substrate, once purged glass are cleaned by using the cleaning solution of the application configuration
Glass substrate is etched thinned again, and the accounting of bad defect is few, and the first-pass yield of glass substrate is up to about 90%, is thrown without follow-up
Light is ground, and is saved production process, is improved production efficiency, while improve product quality.
In conclusion the cleaning solution before the glass thinning for passing through the application is cleaned glass substrate before being thinned, go
Glass substrate is not damaged while there is strong cleaning force except impurity such as the organic substance of the oiliness of glass baseplate surface and residue glues, clearly
Apparent fraction defective of the glass substrate in thinning process after washing reduces, and improves production efficiency and product quality.
The upper only embodiments of the present invention, are not intended to limit the invention.For those skilled in the art
For, the invention may be variously modified and varied.All any modifications made in spirit and principles of the present invention, be equal
Replace, improve etc., it should all be included within scope of the presently claimed invention.
