Problems solved by technology

[0004] Optically variable pigments are made by depositing different materials layer by layer on the coating substrate through vacuum coating technology, and then peeling off and crushing. Residual materials, dust, etc., are difficult to clean. It is difficult to clean them with ordinary cleaning agents and cleaning materials, and acidic corrosive detergents will damage the surface of the substrate. Agent is an important task for manufacturers of optically variable materials

Embodiment 1

[0022] Take 25g of N-(2-aminoethyl)morpholine, 10g of volatile ethylene glycol methyl ether and 65g of water, stir and dissolve, and adjust the pH to neutral with citric acid. The whole production process is carried out in a clean space.

[0023] After cleaning according to the cleaning procedure, the pass rate of the coating film is greater than 99%. And only use N-(2-aminoethyl) morpholine water and adjust the pH value with citric acid to clean the substrate, the qualified rate of coating film under the same standard is only 80%, and the qualified rate of ethylene glycol methyl ether alone is 90-95% .

Embodiment 2

[0025] Take 15g of 4-[2-(dimethylamino)ethyl]morpholine, 15g of ethylene glycol dimethyl ether and 70g of water, stir to dissolve, and adjust the pH to neutral with citric acid. The whole production process is carried out in a clean space.

[0026] After cleaning according to the cleaning procedure, the pass rate of the coating film is greater than 99%. In the comparison test, only 4-[2-(dimethylamino)ethyl]morpholine water and citric acid were used to adjust the pH value to clean the substrate, and the qualified rate of coating was 90-95%. The rate is about 95%.

Embodiment 3

[0028] Take 25g of 4-[2-(dimethylamino)ethyl]morpholine, a total of 10g of ethylene glycol dimethyl ether, ethylene glycol butyl ether, 0.5g of isopropanol and 64.5g of water, stir and dissolve, and use ethylene diol Aminetetraacetic acid disodium salt can adjust the pH to be neutral. The whole production process is carried out in a clean space.

[0029] After cleaning according to the cleaning procedure, the pass rate of the coating film is greater than 99%. In the comparative test, add isopropanol water with 4-[2-(dimethylamino) ethyl] morpholine and adjust the pH value with disodium edetate to clean the substrate, and the qualified rate of coating is 90-98%, while The qualified rate of water with ethylene glycol dimethyl ether, ethylene glycol butyl ether and isopropanol is 95-98%.

Abstract

The invention relates to a substrate cleaning agent and a preparation method thereof, and specifically discloses a cleaning agent for an optical color-changing pigment vacuum-coated substrate and a preparation method thereof. The invention aims to solve the problem of difficult cleaning of various residual materials, dust and the like on a conventional substrate. The cleaning agent is prepared from the following raw materials in percentages by mass: 5 to 30% of an N-ethyl morpholine compound, 1 to 20% of a volatile glycol ether compound and 60 to 80% of water. The preparation method comprisesthe following steps: stirring and dissolving the N-ethyl morpholine compound, the volatile glycol ether compound and the water according to a formula ratio, and regulating an obtained solution to be neutral with an organic acid pH regulator. The cleaning agent for the optical color-changing pigment vacuum-coated substrate provided by the invention can be used for completely cleaning various organic materials, metal oxides, dust and the like on a substrate.

Description

technical field [0001] The invention relates to a cleaning agent for a substrate and a preparation method thereof, in particular to an optically variable pigment vacuum coating substrate cleaning agent and a preparation method thereof. Background technique [0002] Optically variable pigments, that is, optical interference color-changing pigments, are composed of a variety of thin films with different refractive indices, and they will show different colors when viewed from different angles. The basic principle is based on optical thin film multi-beam interference and angle-dependent heterochromatic effect, by using dielectric materials with different refractive indices or transparent metal oxides, using physical vapor deposition method to precisely control the thickness, proportion and sequence of each film layer, They are sequentially deposited on the same carrier (substrate). Under the condition that the incident angle changes, the transmitted or reflected light beam will...
