Embodiment 1

[0023] A kind of optical glass cleaning agent, select raw material by the following percentage by weight of 100 parts in total: 8 parts of sodium hydroxide, 23.5 parts of potassium hydroxide, 0.5 part of tetrasodium EDTA, 2.2 parts of sodium gluconate, 5 parts of nonionic surface active agent , 5 parts of emulsifier, 8 parts of high-efficiency dispersant, 0.8 part of smoothing agent, and the balance of pure water.

[0024] The preparation method is: dissolve sodium gluconate into the pure water of the reaction kettle and stir, then add EDTA-4Na after completely dissolving, add potassium hydroxide and sodium hydroxide after stirring completely, stir at high speed for 2 hours, then cool to 40-50°C and then Add non-ionic surfactants, emulsifiers, and dispersants, stir evenly, and finally add a smoothing agent, stir at a constant speed for 4-6 hours to a clear and transparent solution, and the preparation is complete.

[0025] The emulsifier is Xinben Chemical FMES, the dispersant...

Embodiment 2

[0027] A kind of cleaning agent for optical glass, select raw materials according to the following weight percentages of 100 parts in total, and prepare according to the steps of Example 1.

[0028] 8.8 parts of sodium hydroxide, 21.5 parts of potassium hydroxide, 0.42 parts of tetrasodium EDTA, 2.3 parts of sodium gluconate, 6.7 parts of nonionic surfactant, 5.8 parts of emulsifier, 7.6 parts of high-efficiency dispersant, 0.3 part of lubricant, pure water margin.

[0029] The emulsifier is OP-10, the dispersant is Pingpinga-10, and the smoothing agent is polyethylene glycol: sodium dodecylbenzenesulfonate = 3.5:1 (mass ratio).

Embodiment 3

[0031] A kind of cleaning agent for optical glass, select raw materials according to the following weight percentages of 100 parts in total, and prepare according to the steps of Example 1.

[0032] 7.5 parts of sodium hydroxide, 19.9 parts of potassium hydroxide, 0.73 parts of tetrasodium EDTA, 2.4 parts of sodium gluconate, 5.3 parts of nonionic surfactant, 5.3 parts of emulsifier, 6.8 parts of high-efficiency dispersant, 0.2 part of lubricant, pure water margin.

[0033] The emulsifier is a mixture of OP-10 and OP-15, the dispersant is Tween 60, and the smoothing agent is polyethylene glycol: sodium dodecylbenzenesulfonate = 3.2:1 (mass ratio).

Abstract

The invention provides an optical glass cleaning compound. The optical glass cleaning compound comprises the following raw materials by weight: on the basis of 100 parts, 6 to 8 parts of sodium hydroxide, 20 to 24 parts of potassium hydroxide, 0.4 to 0.6 part of tetrasodium EDTA, 2 to 2.5 parts of sodium gluconate, 4 to 6 parts of nonionic surfactant, 4 to 6 parts of emulsifier, 6 to 9 parts of dispersant and 0.5 to 1.5 parts of a smoothing agent, with the balance being water. The optical glass cleaning compound provided by the invention overcomes the disadvantages of fine scratches, fuzzing and fogging, roughness and the like of the surface of optical glass cleaned with conventional electronic glass cleaning compound and has the advantages of good cleaning effect, easy rinsing, environment friendliness and the like.

Description

technical field [0001] The invention relates to the technical field of glass cleaners, in particular to an optical glass cleaner. Background technique [0002] In the ultrasonic cleaning industry of mobile phone touch glass cover processing, most of them use strong alkaline electronic glass cleaners, which will have surface effects on optical glass during the cleaning process, mainly including: fine scratches on the glass surface, fogging on the glass surface, The surface of the glass is not smooth, and the silk screen layer in the post-process is different in color. Poor cleaning before silk screen printing has always been a problem that plagues various manufacturers. Due to the strong alkalinity of electronic glass cleaners, the glass surface after cleaning is not smooth, which has led to backwashing before silk screen printing in the subsequent process, and a large number of bad colors after screen printing. Rework is required, and some are even scrapped directly, result...
