Description

Technical Field

[0001] The present invention relates to the technical field of cleaning agents, and in particular to an environmentally friendly curtain wall cleaning agent for drones without water marks or stains. Background Art

[0002] With the accelerating pace of urbanization, modern architectural styles are becoming increasingly diverse. Glass curtain walls, as a beautiful and practical building facade material, have been widely used in high-rise buildings. From bustling commercial centers in first-tier cities to emerging landmark buildings in second- and third-tier cities, glass curtain walls can be found everywhere. However, after long-term exposure to the elements, glass curtain walls are highly susceptible to dust, stains, water stains, and other pollutants, which not only affect the building's aesthetics but also reduce its lighting performance and service life.

[0003] Traditional cleaning methods for glass curtain walls primarily involve manual cleaning and hanging basket cleaning. Manual cleaning relies on a "Spider-Man" style of swinging between tall buildings with a rope tied around his waist. This method is extremely inefficient, with a skilled worker only able to clean a few hundred square meters per day. While relatively safer, hanging basket cleaning is cumbersome to install and remove, requiring a long construction period. It is also significantly affected by the weather and cannot be operated in severe weather such as strong winds and heavy rain. Furthermore, traditional cleaning methods often require large amounts of water and use chemical detergents, which inevitably remain on the curtain wall. This not only pollutes the environment but can also corrode the glass surface, shortening its service life and causing harm to the operator. Summary of the Invention

[0004] In response to the problems of high difficulty in cleaning existing curtain walls and residual cleaning agents, the first aspect of the present invention provides an environmentally friendly curtain wall cleaning agent for drones without water marks or stains, which is composed of the following substances in percentage by weight: 10% to 20% emulsifier, 6% to 8% surfactant, 3% to 4% chelating agent, 3% to 5% propellant, 3% to 5% organic solvent, 1% to 2% defoaming agent, 0.5% to 1% photocatalyst, 1% to 2.5% auxiliary agent, and the balance is deionized water.

[0005] Furthermore, the emulsifier is selected from one or more of AEO-3, AEO-6, AEO-7, AEO-9 or Tween 80.

[0006] Furthermore, the surfactant is selected from one or more of APG, lauryl alcohol, oleyl alcohol, lauryl diethanolamine or isomeric tridecyl alcohol polyoxyethylene ether.

[0007] Furthermore, the chelating agent is selected from one of tetrasodium glutamate diacetate, EDTA-2Na, sodium citrate or NTA.

[0008] Furthermore, the propellant is selected from one of methanol, ethanol, isopropanol, propanol, ethyl acetate or turpentine.

[0009] Furthermore, the organic solvent is selected from one of DMF, DMSO, NMP, propylene glycol phenyl ether or N-methylpyrrolidone.

[0010] Furthermore, the defoaming agent is selected from one of aqueous polyether-modified silicone emulsion, polydimethylsiloxane, polyether-modified silicone oil or GPES type defoaming agent.

[0011] Furthermore, the photocatalyst is selected from one of nano-gadolinium oxide, nano-cerium oxide, nano-titanium dioxide or nano-ytterbium oxide.

[0012] Furthermore, the auxiliary agent is a pH regulator.

[0013] The preparation method of the environmentally friendly curtain wall cleaning agent for drones without water marks or water stains of the present invention comprises the following steps: 1. Weigh each component by weight percentage, heat deionized water to 30-50°C, add chelating agent and auxiliary agent, stir at 150-300 rpm for 10-20 minutes, cool to 20-30°C, add surfactant, volatile promoter, and organic solvent in sequence, stir at 200-400 rpm for 20-30 minutes, slowly add photocatalyst, and stir at 150-300 rpm for 15-25 minutes; 2. Filter the stirred liquid in step 1 through 150-300 mesh; 3. Place the filtered liquid from step 2 in a dark place at room temperature for 18 to 36 hours and then fill it.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the synergistic effect of the emulsifier, surfactant and chelating agent in the cleaning agent of the present invention enables the cleaning machine to tolerate 600ppm of hard water without forming scale or white edges, and is suitable for water quality in most areas. After spraying, the organic solvent and the propellant will evaporate quickly under the joint action of the organic solvent and the propellant, which can effectively prevent the secondary precipitation of inorganic matter and avoid secondary washing. The combination of the photocatalyst and the defoaming agent can make the cleaned glass surface brighter, prevent dust from being adsorbed on the glass surface under the action of static electricity, and at the same time play the role of nanomaterials under sunlight conditions, decompose stains, and extend the cleaning cycle. The environmentally friendly curtain wall cleaning agent of the present invention has the characteristics of high cleaning efficiency, is neutral and non-corrosive, is suitable for loading on drones, and avoids the safety hazards of manual cleaning.
