Description

Technical Field

[0001] This invention relates to the field of cleaning agent technology, and in particular to an acrylic glass cleaning agent and its preparation method. Background Technology

[0002] Acrylic glass is a polymer compound made from methyl methacrylate (MDMA). It has advantages such as good transparency, chemical stability, mechanical properties, and ease of processing. Contaminants on the surface of acrylic glass will reduce its light transmittance and affect its appearance, and are difficult to clean thoroughly with commonly used cleaning agents. Most commercially available acrylic glass cleaners are acidic or alkaline, which can easily corrode the acrylic glass; or the cleaned acrylic glass may generate static electricity, resulting in poor dust resistance. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an acrylic glass cleaning agent and its preparation method. The cleaning agent prepared by this invention is a highly efficient, pollution-free, neutral cleaning agent that improves the light transmittance and haze performance of acrylic glass after use. It is harmless to the human body and has no irritating odor.

[0004] To achieve this technical objective, the present invention adopts the following solution:

[0005] An acrylic glass cleaner, comprising, by volume, 100 parts deionized water, 10-20 parts ethanol, 0.4-0.6 parts emulsifier, 1.0-1.6 parts surfactant, and 1.1-1.3 parts pH balancer.

[0006] Furthermore, the surfactant is coconut oil fatty acid diethanolamide and lauryl alcohol polyoxyethylene ether-3, with a volume ratio of 0.8~1.2:0.25~0.35.

[0007] Furthermore, the emulsifier is Span 20, the pH balancer is triethanolamine, and the volume concentration of ethanol is 95%.

[0008] On the other hand, the present invention provides a method for preparing an acrylic glass cleaner, wherein an appropriate amount of deionized water is weighed, and ethanol, emulsifier, surfactant and pH balancer are added sequentially under stirring, and the acrylic glass cleaner is obtained after stirring evenly.

[0009] The surfactants are added in the following order: first, coconut oil fatty acid diethanolamide, then lauryl alcohol polyoxyethylene ether-3. The acrylic glass cleaner prepared according to this method is stable, does not separate upon standing, and exhibits good cleaning performance.

[0010] Furthermore, the stirring time after adding the emulsifier should be greater than or equal to 5 minutes. This ensures that the emulsifier is fully dispersed in the deionized water before adding the coconut oil fatty acid diethanolamide. Otherwise, the solution will separate into layers after settling, thus losing its original function.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] This invention relates to a neutral, transparent liquid for cleaning acrylic glass. It does not chemically corrode acrylic glass sheets. The cleaning agent contains ethanol, coconut oil fatty acid diethanolamide, and deionized water, which, when mixed, form a non-ionic antistatic agent. The combined use of Span 20 and lauryl alcohol polyoxyethylene ether-3 enhances its cleaning power. This cleaning agent can be sprayed onto the surface of acrylic glass sheets before machining, leaving the surface free of sawdust, impurities, and dust after machining. It can also be used to clean residual polishing solution after polishing acrylic glass surfaces. Detailed Implementation

Next, add 3 mL of lauryl alcohol polyoxyethylene ether-3, stir for 5 minutes, then add 10 mL of coconut oil fatty acid diethanolamide, stir for 5 minutes. During stirring, white foam will appear on the surface of the liquid. Add 12 mL of triethanolamine, and stop stirring after 5 minutes. After standing for 10 minutes, the foam disappears, and the cleaning agent shows stratification, with an oily liquid floating on the surface. The cleaning agent should be shaken well before testing. Comparative Example 4

[0020] First, take 150 mL of 95% ethanol and add 5 g of Span 60 (sorbitan monostearate) to the ethanol. Stir for 5 minutes until Span 60 is fully dissolved in the ethanol, and the solution is a light yellow liquid. Add the above solution to deionized water and stir for 5 minutes. Then add 10 mL of coconut oil fatty acid diethanolamide. After stirring for a certain period of time, white foam will appear on the surface of the liquid. Then add 3 mL of lauryl alcohol polyoxyethylene ether-3 and stir for 5 minutes until the foam disappears. Then add 12 mL of triethanolamine and stop stirring after 5 minutes to obtain the acrylic glass cleaner.

[0021] Span 60 is a white to pale yellow powder, wax, or lumpy substance. It is dispersible in hot water and miscible with oils and common organic solvents. Therefore, in this embodiment, it is dissolved in ethanol before adding deionized water. Comparative Example 5

[0022] First, measure 150 mL of 95% ethanol. Add 5 g of Span 80 (sorbitan monooleate) to the ethanol and stir for 5 minutes until Span 80 is fully dissolved in the ethanol. The solution is a light yellow liquid. Add the above solution to deionized water and stir for 5 minutes. Then add 10 mL of coconut oil fatty acid diethanolamide. After stirring for a certain period of time, white foam will appear on the surface of the liquid. Then add 3 mL of lauryl alcohol polyoxyethylene ether-3 and stir for 5 minutes until the foam disappears. Then add 12 mL of triethanolamine and stop stirring after 5 minutes to obtain the acrylic glass cleaner.

[0023] Span 80 is an amber-colored, viscous, oily substance, insoluble in water. It is soluble in common hot oils and organic solvents. Therefore, in this embodiment, it is dissolved in ethanol before adding deionized water. Comparative Example 6

[0024] First, weigh 1000 mL of deionized water, start stirring, add 150 mL of 95% ethanol, stir for 1 minute, then add 5 mL of Span 20, stir for 5 minutes until the Span 20 is fully dissolved in the liquid, resulting in a light yellow, oily liquid. Next, add 10 mL of coconut oil fatty acid diethanolamide. After stirring for a certain period, white foam will appear on the surface of the liquid. Then add 3 mL of sodium fatty alcohol polyoxyethylene ether sulfate (AES), stir for 5 minutes until the foam disappears, then add 12 mL of triethanolamine. After 5 minutes, stop stirring to obtain the acrylic glass cleaner. After standing for 20 minutes, a small amount of gelation appears at the bottom of the cleaner. A pH test with pH paper shows a pH value of approximately 4.5.

[0025] The performance of the acrylic glass cleaner of the present invention was tested using the following method. The test was conducted using aviation acrylic glass sheet YB-DM-10 produced by Jinxi Chemical Research Institute Co., Ltd. Cleaning agents from different embodiments were used to wipe the surface of the same batch of sheet. The test results are shown in Table 1.

[0033]

[0034] As shown in Table 1, the acrylic glass cleaner of the present invention is a neutral cleaner with strong detergency and no chemical corrosion to acrylic glass sheets. The addition of ethanol, coconut oil fatty acid diethanolamide and deionized water to the cleaner forms a non-ionic antistatic agent, which effectively prevents static electricity. The combined use of Span 20 and lauryl alcohol polyoxyethylene ether-3 can enhance the detergency.
