Problems solved by technology

[0003] However, for the cleaning of optical coatings, the current bottleneck is to use alkaline cleaning agents and ultrasonic (normal heating process) cleaning, which is easy to wash off the coatings, but it is difficult to achieve a certain gloss with neutral ones, and the defects are obvious

Embodiment 1

[0021] Weigh 2.8 kg of tetrasodium edetate, 1.2 kg of potassium pyrophosphate, 3.2 kg of sodium acetate, 3 kg of nonionic surfactant, 1 kg of sodium cumene sulfonate, 1.5 kg of fatty acid alkanolamide, and 87.3 kg of pure water. In the container, stir evenly to obtain a neutral detergent.

[0022] Tetrasodium ethylenediaminetetraacetic acid (ETDA4Na) mainly plays a role in water softness and complexation.

[0023] In practical application, it is necessary to mix and dilute the neutral cleaning agent of the present invention with water at a ratio of 1:20, and the effect of potassium pyrophosphate can also produce the effect of dispersing oil stains without certain alkalinity. It has a good effect on removing white spots on the optics, and can also play a role in buffering, emulsifying, and integrating. Pyrophosphate ions have a good dispersing effect on dotted coating.

[0024] In this example, the compounded nonionic surfactant is a low-foaming ethoxy-propoxyl C8-C10 fatty a...

Embodiment 2

[0029] Weigh 3.5kg of tetrasodium edetate, 1kg of potassium pyrophosphate, 1.5kg of sodium acetate, 4kg of nonionic surfactant, 1.5kg of sodium cumene sulfonate, 1kg of fatty acid alkanolamide, and 87.5kg of pure water in In the container, stir evenly to obtain a neutral detergent. It is very well mixed in the synthesis of the overall formula ingredients, without turbidity and precipitation. The pH value of this neutral cleaning agent is 8.0, the cost of compatibility is low, and it can completely replace the high price of imported products. Now the field of optical coating is more and more extensive, and it is favored by the majority of processing and manufacturing enterprises. The progress is obvious and the practicability powerful.

Embodiment 3

[0031] Weigh 4kg of tetrasodium edetate, 0.8kg of potassium pyrophosphate, 2kg of sodium acetate, 4kg of nonionic surfactant, 1.5kg of sodium cumene sulfonate, 1.5kg of fatty acid alkanolamide, and 86.2kg of pure water in In the container, stir evenly to obtain a neutral detergent. It is very well mixed in the synthesis of the overall formula ingredients, without turbidity and precipitation. The pH value of the neutral cleaning agent is 8.2, the cost of compatibility is low, and it can completely replace the high price of imported products. Now the field of optical coating is more and more extensive, and it is favored by the majority of processing and manufacturing enterprises. The progress is obvious and the practicability stronger.

Abstract

The invention relates to the technical field of cleaning of plated products, and especially relates to a neutral detergent for optical plating. The neutral detergent comprises, by weight, 2.8-5.3% of tetrasodium ethylenediamine tetraacetate, 0.5-1.2% of potassium pyrophosphate, 1-3.2% of sodium acetate, 3-5.3% of a nonionic surfactant, 1-2% of sodium cumenesulfonate, 1-2% of fatty acid alkanolamide, and the balance of pure water. The neutral detergent is weakly alkaline, has no deterioration, misting or mildewing phenomena, and can promote cleaning. The neutral detergent does not destroy a plating film after the neutral detergent is used to clean the plating film under a weakly alkaline condition. The neutral detergent is very well mixed in the synthesis process of integral formula components without turbidity or precipitation. The neutral detergent has low compatibility cost, can completely substitute imported products with high price, can be widely applied to the field of optical plating, is well accepted by general processing manufacturing enterprises, has obvious progress, and has strong practicality.

Description

technical field [0001] The invention relates to the technical field of cleaning coating products, in particular to a neutral cleaning agent for optical coatings. Background technique [0002] Nowadays, the field of scientific and technological optics continues to advance, and the original ordinary mobile phone cover is just ordinary flat and smooth. Now the optical cover is plated with a layer of AF film by vacuum coating technology in order to increase the foundation of smoothness, wear resistance and beauty. After coating, the hand looks smooth, and the water droplets drip on the coated panel, and the water droplets will not spread around. When tilted, the whole water drop rolls together, and the panel has a glossy feel. [0003] However, for the cleaning of optical coatings, the current bottleneck is to use alkaline cleaning agents and ultrasonic (normal heating process) cleaning, which is easy to wash off the coatings, but it is difficult to achieve a certain gloss with...
