Embodiment 1

[0032] Raw materials (mass percentage) consist of: sodium hydroxide 2%, sodium lauryl sulfate 0.5%, sodium fatty acid methyl ester sulfonate 0.3%, lauryl glucoside 0.3%, film-forming agent (mass ratio is 1: 1 ethanol and ethylene glycol mixture) 35%, corrosion inhibitor (sodium citrate and triethanolamine mixture with a mass ratio of 1:1) 0.4%, chelating agent (disodium edetate) 0.5%, the balance for deionized water.

[0033]The preparation method is: take an appropriate amount of deionized water, dissolve it into sodium hydroxide, and keep stirring until it is completely dissolved, put it in a constant temperature water tank, and control the temperature at about 40°C, then add anionic surfactant, nonionic surface active agent and Active agent, film forming agent, corrosion inhibitor, chelating agent, every time a raw material is added, it needs to be fully stirred. Finally, keep stirring until the solution is clear and transparent, and the preparation is completed.

Embodiment 2

[0036] The preparation method is the same as in Example 1, and the raw materials (mass percentage) consist of: 4% sodium hydroxide, 0.3% sodium lauryl sulfate, 0.2% sodium fatty acid methyl ester sulfonate, 0.4% lauryl glucoside, film-forming agent (a mixture of ethanol and ethylene glycol in a mass ratio of 1:1) 25%, a corrosion inhibitor (a mixture of sodium citrate and triethanolamine in a mass ratio of 1:1) 0.7%, a chelating agent (ethylenediaminetetraacetic acid di sodium salt) 0.8%, and the balance is deionized water.

[0037] Use this cleaning agent formula to clean the glass dirt with strong adhesion and aging and solidification, and the removal rate is 99.67%. After cleaning, the glass surface has high cleanliness, good transparency, no water streaks, and no pollution when wiped with filter paper.

Embodiment 3

[0039] The preparation method is the same as in Example 1, and the raw materials (mass percentage) consist of: 6% sodium hydroxide, 0.3% sodium lauryl sulfate, 0.3% sodium fatty acid methyl ester sulfonate, 0.2% lauryl glucoside, film-forming agent (a mixture of ethanol and ethylene glycol at a mass ratio of 1:1) 15%, a corrosion inhibitor (a mixture of sodium citrate and triethanolamine at a mass ratio of 1:1) 1.0%, a chelating agent (ethylenediaminetetraacetic acid di sodium salt) 1.0%, and the balance is deionized water.

[0040] Use this cleaning agent formula to clean the glass dirt with strong adhesion and aging and solidification, and the removal rate is 99.69%. After cleaning, the glass surface has high cleanliness, good transparency, no water streaks, and no pollution when wiped with filter paper.

Abstract

The invention discloses an environment-friendly optical glass cleaning agent and a preparation method thereof. The environment-friendly optical glass cleaning agent is prepared from the following raw materials in percentage by mass: 2 to 6 percent of inorganic alkali, 0.5 to 0.8 percent of anionic surfactant, 0.2 to 0.4 percent of non-ionic surfactant, 15 to 35 percent of film-forming agent, 0.4 to 1.0 percent of corrosion inhibitor, 0.5 to 1 percent of chelating agent and the balance of deionized water, wherein the anionic surfactant is prepared from sodium lauryl sulfate and fatty acid methyl ester sulfonate in a mass ratio of (5:1) to (1:1); the non-ionic surfactant is prepared from dodecyl glycoside; the film-forming agent is prepared from ethanol and ethylene glycol in a mass ratio of 1:1; the corrosion inhibitor is prepared from sodium citrate and triethanolamine in a mass ratio of 1:1. The optical glass cleaning agent disclosed by the invention has the advantages of good cleaning effect, high cleanliness of cleaned glass, no corrosion to the glass, high biodegradability, freeness from pollution, and low skin irritation.

Description

technical field [0001] The invention belongs to the technical field of glass surface cleaners, and in particular relates to an environment-friendly optical glass cleaner and a preparation method thereof. Background technique [0002] In the production process of glass, a series of complex processing procedures are required, such as cutting, edging, grinding, polishing and so on. These processes generally require specific cutting fluid, edging oil, grinding fluid, polishing powder, etc. to assist the operation. Inevitably, the glass will be affected by the aids of related processes (such as glass chips, glass powder, cutting fluid remaining on the glass surface after cutting, rare earth, silica polishing powder remaining after polishing, grinding powder and asphalt left after grinding, etc. ) pollution. Therefore, glass cleaning is extremely necessary. In recent years, with the wide application of optical glass such as display screens, mobile phone glass covers, and touch ...
