Description

Technical Field

[0001] The invention relates to the field of mold release agent cleaning, and in particular to a cleaning agent composition, a cleaning agent, and a preparation method and application thereof. Background Art

[0002] In house decoration, ceramic tiles are a common floor and wall decoration material. However, when ceramic tiles are fired out of the kiln or packaged and stored, manufacturers usually apply a layer of release agent on the back of the ceramic tiles to prevent the ceramic tiles from sticking to each other or to the packaging materials.

[0003] This layer of release agent needs to be removed when laying tiles, otherwise it will have an isolation effect during the tile bonding process, affecting the tile pasting effect. Therefore, before laying tiles, you must first clean the release agent on the back of the tile, and then lay the tiles. The common methods for cleaning tile release agents in the market are as follows:

[0004] 1. Water flushing method

[0005] This is the simplest and most direct method. First, place the back of the tile facing up and rinse the back of the tile with tap water to fully wet the release agent. Then, gently wipe the back of the tile with your hands or a brush until the release agent is completely removed. This method is suitable for situations where the release agent is thin and easy to clean.

[0006] 2. Sandpaper polishing method

[0007] If the water washing method cannot completely remove the release agent, you can try to use sandpaper polishing. First, turn the back of the tile upwards and gently polish the back of the tile with sandpaper (80-mesh or 100-mesh sandpaper is recommended) to remove the release agent. During the polishing process, pay attention to maintaining the contact area between the sandpaper and the back of the tile to ensure the polishing effect. In addition, pay attention to controlling the polishing force to avoid damaging the tile surface.

[0008] 3. Chemical cleaning method

[0009] For stubborn release agents, chemical cleaning agents can be used for cleaning. There are cleaning agents on the market specifically for cleaning release agents on the back of tiles, which can be operated according to the product instructions. When using chemical cleaning agents, be sure to wear gloves and masks to avoid irritation to the skin and respiratory tract. In addition, pay attention to the concentration of the cleaning agent and the cleaning time to avoid damage to the tile surface.

[0010] However, the above three methods have the following problems:

[0011] Materials: Use clean water to rinse the back of the tile, which is more to remove the water-based release agent, while the oil-based release agent for tiles cannot be dissolved in water and cannot be effectively cleaned. Sandpaper can easily damage the surface of the tile, and the release agent in the corners and gaps cannot be effectively cleaned. In addition, it needs to be cleaned with water after grinding, which is inefficient. At the same time, this method is not effective for cleaning organic release agents. When using chemical cleaning agents for cleaning, be sure to wear gloves and masks to avoid irritation to the skin and respiratory tract. In addition, pay attention to the concentration of the cleaning agent and the cleaning time to avoid damage to the tile surface, which is very harmful.

[0012] CN116904271A discloses a square tile decontamination cleaning agent, which includes the following raw materials: volatile organic solvent, surfactant, nano carbon powder, silver ion antibacterial agent, emulsifier, inorganic alkali; its specific formula includes the following raw materials: volatile organic solvent 100-200g, surfactant 30-50g, nano carbon powder 40-60g, silver ion antibacterial agent 5-10g, emulsifier 3-5g, inorganic alkali solution 5-10g. However, the cleaning agent of this scheme contains organic solvent, which has harmful effects on the body and the environment, and this technical scheme is only effective for organic tile release agents, and has no obvious cleaning effect on inorganic release agents.
