Embodiment 1

[0034] Embodiment one of the present invention firstly provides a kind of cleaning liquid that is applied to optical glass substrate, and it specifically comprises the following components by weight percentage: inorganic alkaline substance (KOH) 5.7%; Potassium carbonate (K2CO3) 2.7%; Fatty alcohol and Quaternary ammonium alcohol ether copolymer 0.03%; deionized water 91.57%. Secondly, if figure 1 As shown, a cleaning solution applied to optical glass substrates provided by Embodiment 1 of the present invention is obtained by the following preparation method:

[0035] S1: pass tap water through water-making equipment 1 to produce pure water, and detect the conductivity of the effluent;

[0036] S2: put the produced high-purity water into the first liquid storage tank 2, and cool it to a suitable temperature through the cooler 3;

[0037] S3: Store the cooled high-purity water in the second liquid storage tank 5, then add inorganic alkaline substances through the feeding cont...

Embodiment 2

[0042] Others are the same as those described in Embodiment 1, except that a cleaning solution applied to optical glass substrates provided by Embodiment 2 of the present invention includes the following components in weight percentage: inorganic alkaline substance (KOH) 10.1%; Potassium carbonate (K2C03) 1.4%; Sodium metasilicate (NaSi03) 0.1%; Fatty alcohol and quaternary ammonium salt alcohol ether copolymer 0.01%; Deionized water 88.39%. Embodiment three:

Embodiment 3

[0043] Others are the same as those described in Embodiment 1, except that a cleaning solution applied to optical glass substrates provided by Embodiment 3 of the present invention includes the following components in weight percentage: inorganic alkaline substance (KOH) 8.8%; Potassium carbonate (K2C03) 2%; Potassium chloride (KCI) 0.5%; Fatty alcohol and quaternary ammonium salt alcohol ether copolymer 0.02%; Deionized water 88.68%.

[0044] In order to further observe the cleaning effect of a kind of cleaning solution applied to optical glass substrates provided by the above-mentioned embodiments 1 to 3, the present invention adopts the following experimental means, that is, using the optical glass substrate of the photoelectric display material as the test object, and cutting 3cm*4cm Small pieces with fingerprints, dirt, glass shards and other problems on them, then immersed in 100ml of cleaning solution (this cleaning solution is obtained by diluting the cleaning solution ...

Abstract

The invention provides a cleaning liquid applied to an optical glass substrate. The cleaning liquid comprises the following components in percentages by weight: 3 to 20% of an inorganic alkaline substance, 1 to 4% of potassium salt and 0.01 to 0.05% of a non-ionic surfactant, with the balance being deionized water, wherein the above-mentioned deionized water is prepared by an RO reverse osmosis method, is pure water with impurities removed in an ion form, and is also called as ultrapure water and pure water and high-purity water. The invention provides a preparation method for the cleaning liquid applied to the optical glass substrate. The cleaning liquid provided by the invention has the following positive effects: fingerprints, stains and fine particles remaining on the optical glass substrate can be effectively removed, and no corrosion to the optical glass substrate is generated at the same time; meanwhile, the cleaning liquid is free of high requirements on a temperature and equipment of a use environment, has simple and convenient operation, and is safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of optical glass material cleaning, and in particular relates to a cleaning liquid applied to optical glass substrates and a preparation method, and more particularly to a cleaning solution for cleaning surface stains and particles of flat glass and optical glass substrates after cutting and polishing Cleaning solution and preparation method. Background technique [0002] Optical glass substrates are important optical components of liquid crystal display devices. Fingerprints, dust, oil, and other organic or inorganic particles will adhere to the surface before coating. These impurities will affect the quality of optical glass substrates and reduce the quality of liquid crystal display devices. The qualified rate, so the label of the optical glass substrate needs to be cleaned before coating. The existing cleaning solutions for optical glass substrates mainly include water-based cleaning solutions and solut...
