Description
Technical Field
The invention relates to a low-reflection glass cleaning agent for a museum showcase and a preparation method thereof, and belongs to the technical field of glass cleaning agents.
Background
The low-reflection glass for the museum showcase is magnetron sputtering coated glass, the surface of the magnetron sputtering coated glass is in a hydrophobic state, and the water contact angle is 60 degrees. And the surface hydrophobic angle of the conventional ultra-white glass is about 30 degrees. The larger hydrophobic angle of the low reflection glass makes the requirements on the cleaning agent stricter. The cleaner needs to be fully soaked on the surface of the low-reflection glass film, so that a good cleaning effect can be achieved.
The existing common cleaning agent, such as glass cleaning agent in electronic industry, comprises the following components: alkaline substances, polyhydric alcohol, thickening agent, fluorine-containing surfactant, complexing agent, defoaming agent, deionized water and the like; the optical glass cleaning agent consists of a surfactant, a complexing agent, organic alkali, a penetrating agent and deionized water. The low-reflection glass is cleaned by adopting a glass cleaning agent and an optical glass cleaning agent in the electronic industry, and the low-reflection glass does not have an anti-fog effect.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a low-reflection glass cleaning agent for a museum showcase and a preparation method thereof, and the specific technical scheme is as follows:
a low-reflection glass cleaner for museum showcases comprises the following components in percentage by weight:
the balance of water.
As an improvement of the technical scheme, the nonionic surfactant is one or more of alkyl glycoside, polyoxyethylene type nonionic surfactant, polyhydric alcohol type nonionic surfactant, alkanolamide type nonionic surfactant, polyether type nonionic surfactant and amine oxide type nonionic surfactant.
As an improvement of the technical scheme, the defoaming agent is one or more of dimethyl polysiloxane, polydimethylsiloxane and polyether modified silicone oil.
As an improvement of the technical scheme, the solvent for the defoaming agent is one or more of alcohol, isopropanol and propanol.
As an improvement of the technical scheme, the antistatic agent is one or more of fatty acid monoglyceride and ethoxy lauryl tyramine.
As an improvement of the technical scheme, the solvent for the antistatic agent is one or more of ethylene glycol, ethanol and propanol.
The low-reflection glass cleaning agent for the museum showcase comprises the following components in percentage by weight:
the balance of water.
The preparation method of the low-reflection glass cleaning agent for the museum showcase comprises the following steps:
step one, dissolving an antifoaming agent (dimethyl polysiloxane) in an antifoaming agent solvent (isopropanol) to prepare an antifoaming agent solution;
dissolving an antistatic agent (fatty acid monoglyceride) in an antistatic agent solvent (ethylene glycol) to prepare an antistatic agent solution;
and step three, uniformly mixing and dispersing the nonionic surfactant (alkyl glycoside), the defoaming agent solution, the antistatic agent solution and water to obtain the low-reflection glass cleaning agent for the museum showcase.
As an improvement of the technical scheme, the low-reflection glass cleaning agent for the museum showcase is applied to cleaning low-reflection coated glass.
The surfactant used in the invention is a nonionic surfactant which has better wetting, emulsifying, dispersing and solubilizing functions, is not ionized in water and has good stability.
The nonionic surfactant used in the present invention is preferably an alkyl glycoside. The alkyl glycoside has the advantages of low surface tension, no cloud point, adjustable HLB value, strong wetting power, strong detergency, strong compatibility, no toxicity, no harm, no stimulation to skin, rapid and thorough biodegradation, capability of being compounded with any type of surfactant and obvious synergistic effect. Has strong broad-spectrum antibacterial activity, obvious product thickening effect, easy dilution, no gel phenomenon and convenient use. But also has strong alkali resistance, strong acid resistance, hard water resistance and strong salt resistance. The wetting property can be improved by increasing the dosage of the alkyl glycoside; however, as the level of alkyl glycoside increases, it has been found in experiments that this results in a significant amount of foam in the finished product. Therefore, an antifoaming agent is incorporated into the formulation, preferably a dimethylpolysiloxane is used to reduce the surface tension and suppress the foaming properties of the alkyl glycoside. When the mass ratio between the alkyl glycoside and the dimethylpolysiloxane is 2:1, both the wettability by the alkyl glycoside and the effect of suppressing foaming can be optimized. When the content of the alkyl glycoside is 1%, the content of the dimethylpolysiloxane is 0.5%.
In addition, in experiments, alkyl glycoside can improve the wetting property, and also enables the low reflection glass cleaned by the cleaning agent (short for the low reflection glass cleaning agent for the museum showcase) to have the anti-fog property.
Since dimethylpolysiloxane is insoluble in water, conventional detergents are usually prepared by dissolving dimethylpolysiloxane in alcohol and then dissolving it in a detergent. According to the invention, dimethyl polysiloxane is dissolved in isopropanol, and the isopropanol can not only increase the dissolving performance, but also can be matched with alkyl glycoside to increase the antifogging performance. The optimal ratio of the alkyl glycoside to the dimethyl polysiloxane to the isopropanol is 2:1:16, and the antifogging performance is optimal.
In order to increase the antistatic performance of the detergent, the invention achieves the antistatic effect by dissolving the fatty acid Monoglyceride (MG) in the glycol.
As is well known in the art: the top layer material of the low-reflection coated glass is usually titanium oxide. The introduction of ethylene glycol can further improve the antistatic effect due to the excess amount of ethylene glycol in addition to the use as a solvent. The optimal mass ratio of the fatty acid monoglyceride to the ethylene glycol is 1: 3.
The invention has the beneficial effects that:
the low-reflection glass cleaning agent for the museum showcase is used for cleaning low-reflection glass, has a good cleaning effect and a certain anti-fog effect, and meanwhile, the cleaned low-reflection glass has a certain anti-static performance, so that the cleaned low-reflection glass can be kept clean for a long time (such as 48 hours), and the low-reflection glass cleaning agent is good in implementation effect and high in application value and is particularly suitable for being applied to the museum showcase.

and (4) adopting a microscopic image analysis system to characterize the surface of the glass after dust is adsorbed. The particle size and the number of the dust adhered to the glass surface are analyzed by an image analysis system, and the dust adsorption condition of the glass surface treated by different methods can be characterized, and the results are shown in table 3.
TABLE 3
In the above examples, according to examples 1 to 3 and the initial antifogging effect test, the long antifogging effect test, the antistatic effect test, the results found that:
besides the improvement of the wettability, the alkyl glycoside enables the low-reflection glass cleaned by the cleaning agent (the low-reflection glass cleaning agent for the museum showcase is short) to have antifogging property, and the initial antifogging effect and the long-term antifogging effect are excellent.
By comparing the analysis of examples 1 and 2 and examples 1 and 3, it can be seen that the anti-fogging performance enhanced by using isopropanol is significantly better than that of using alcohol.
The mass ratio of the alkyl glycoside, dimethyl polysiloxane and isopropanol was adjusted to 1:0.5: y. According to different y values, corresponding samples 1-3 and samples X1-10 prepared according to the formula of Table 4, and the fogging time t of the samples X1-10 was tested according to an initial anti-fogging effect test.
TABLE 4
The plot of the content y of isopropanol against the fogging time t is shown in FIG. 1, from which it can be seen that, at the maximum value of t, y is equal to 8 or 9.5; therefore, the antifogging performance is optimal when y is equal to 8, namely the optimal ratio of the alkyl glycoside to the dimethyl polysiloxane to the isopropanol is 2:1: 16.
The monoglyceride of the invention is replaced by polyglycerol fatty acid ester and sorbitan fatty acid ester of antistatic agent, but neither polyglycerol fatty acid ester nor sorbitan fatty acid ester can lead the low-reflection coated glass to have antistatic effect (the number of the dust particle diameter of 0.8um on the surface of the glass exceeds 50 after the glass is placed for 24 hours).
The antistatic effect test was carried out using the cleaned ultra-white glass of sample 3, and the number of dusts having a particle size of 0.5um or more existing on the glass surface after 24 hours of storage was more than 50 under the conditions of 25 ℃ and 30% RH.
By continuously adjusting the content of ethylene glycol, corresponding sample Z1-8 (wherein, water or alcohol can be heated to 70 ℃ for dissolving fatty acid monoglyceride) prepared according to the formulation of Table 5 according to the content of ethylene glycol was used, and after cleaning the low reflection glass, an antistatic effect test was performed using sample Z1-8, and the number and particle size of dust on the surface of the glass after leaving for 72 hours under the conditions of 25 ℃ and 30% RH were measured, and the results are shown in Table 6.
TABLE 5
Component (%) | Sample Z1 | Sample Z2 | Sample Z3 | Sample Z4 | Sample Z5 | Sample Z6 | Sample 3 | Sample Z7 | Sample Z8 |
Isopropanol (I-propanol) | 8 | 8 | 8 | 8 | 8 | 8 | 8 | 8 | 8 |
Dimethylpolysiloxane | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 |
Alkyl glycosides | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |

TABLE 6
From tables 5 and 6, it can be seen that: the anti-static effect can be improved by adding the fatty acid monoglyceride into the cleaning agent, and the anti-static effect can be further improved by adding the excessive glycol; and the ethylene glycol added alone has no antistatic effect. When the content of ethylene glycol is increased to a certain degree, the antistatic effect reaches a limit. Therefore, the optimal mass ratio of the fatty acid monoglyceride to ethylene glycol is 1: 3.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
