Description

Technical Field

[0001] The invention relates to the technical field of cleaning agents, and in particular to a special cleaning agent for blackened interior decoration, and a preparation method and application thereof. Background Art

[0002] The main materials of vehicle interior parts are usually paint and hard plastic, which are designed for durability, aesthetics and easy cleaning. However, in daily use, the surface of vehicle interior parts is prone to accumulate various dirt, especially the phenomenon of blackening of the surface. Such blackened stains may come from a variety of factors, such as hand sweat, skin oil, dust, food residue, smoke, pollutants in the air, and oxidation caused by long-term exposure to sunlight in the vehicle interior. These pollution sources gradually deposit and penetrate into the paint or plastic surface under different vehicle use environments, forming a layer of stubborn stains, which greatly affects the appearance and usability of the vehicle interior.

[0003] Traditionally, common cleaning agents on the market, such as neutral detergents, surfactants, and some special car interior cleaning products, are mainly used for general dust and surface pollutants. They separate stains from materials by dissolving or emulsifying them. However, when encountering stubborn black stains, these cleaning agents are often ineffective. This is because black stains usually do not just stay on the surface of the material, they may have physically or chemically combined with the surface of the material at a deep level, especially after long-term use of paint or hard plastic, tiny cracks or pores may appear on the surface of the material, which provides conditions for the penetration of pollutants.

[0004] Further analysis of the characteristics of paint and hard plastic shows that paint usually has a certain degree of gloss and smoothness, and is not easy to adhere to dirt in the early stage. However, during use, the wear, aging, and ultraviolet radiation of the paint will cause its surface to gradually lose its original protective layer, become rough, and even oxidize. These physical changes make it easier for dirt to adhere to the surface and penetrate it, forming black stains that are difficult to clean. Hard plastic is relatively durable, but its surface usually has tiny textures or processing marks. It is also easy to oxidize and age when exposed to air or sunlight for a long time. The particles, oil stains and other organic matter adsorbed on the surface are difficult to completely remove by ordinary cleaning methods.

[0005] In order to thoroughly clean this black stain, it is obviously not effective to rely solely on the physical action of ordinary detergents. Some high-efficiency detergents currently on the market remove stains through stronger chemical effects, such as using organic solvents to dissolve pollutants, or using more efficient surfactants to reduce the adhesion between dirt and the surface of the material. However, this type of detergent may improve the cleaning effect, but damage to materials has also become a problem that cannot be ignored. For example, some strong solvents can cause irreversible corrosion to paint or plastics, causing them to lose their gloss, discolor, and even produce surface cracks. In addition, the ingredients in some chemical cleaners may also be potentially harmful to the human body and the environment, and frequent use may cause health problems or environmental pollution.

[0006] Based on the material characteristics of vehicle interior materials and the nature of pollutants, it is particularly important to develop new cleaning technologies or products. On the one hand, it is necessary to develop cleaning agents that can deeply penetrate the micropores on the surface of the material, and its ingredients should be able to effectively decompose stubborn stains, especially those complex pollutants formed by a mixture of grease, carbon particles and oxides; on the other hand, such cleaning agents must also ensure a strong cleaning effect while avoiding damage to the paint and hard plastic materials. In recent years, although the existing cleaning agents on the market can remove dirt to a certain extent, they are often not effective in removing deep stains. Many cleaning agents contain strong chemical ingredients. Although they can remove surface dirt in the short term, long-term use may cause paint fading or hard plastic aging, thereby accelerating damage to the interior.

[0007] Based on this, it is urgent to develop a non-polluting, purely neutral, easily degradable, blackening cleaning agent with a high cleaning rate to solve the above problems. Summary of the invention

[0008] The purpose of the present invention is to develop a non-polluting, purely neutral, easily degradable cleaning agent with a high blackening cleaning rate.

[0009] The first aspect of the present invention is:

[0010] A cleaning agent is provided.

[0011] The second aspect of the present invention is:

[0012] Provided is a method for preparing a cleaning agent.

[0013] The third aspect of the present invention is:

[0014] Application of the cleaning agent.

[0015] The invention also provides a vehicle interior cleaning agent.

[0016] Specifically, the technical solution adopted according to the first aspect of the present invention is:

[0017] A cleaning agent comprising the following components:

[0018] Emulsifiers;

[0019] Detergents;

[0020] Penetrants;

[0021] Corrosion inhibitors;

[0022] water;

[0023] The emulsifier includes at least one of ethylene glycol glucoside, tetradecyl glucoside and alkyl glucoside.

[0024] According to the embodiments of the present invention, one of the technical solutions has at least one of the following advantages or beneficial effects:

[0025] The present invention can significantly improve the cleaning effect and reduce the corrosiveness by adding a builder, a penetrant and a corrosion inhibitor to the cleaning agent. This is because the builder, the penetrant and the corrosion inhibitor can enhance the adhesion and penetration of the emulsifier on the cleaning surface, further improve the encapsulation and adsorption of the emulsifier on the dirt, thereby effectively reducing the surface tension between water and oily dirt. The emulsifier gradually penetrates, penetrates into the surface of the cleaning object, and reaches the interface between it and the oily dirt, wherein one of (tea saponin, sodium nitrilotriacetate and EDTA) and one of (ethanol, diethylene glycol butyl ether and Tween 80) (sodium nitrilotriacetate + diethylene glycol butyl ether) have an excellent penetration effect. At this time, the emulsifier undergoes directional adsorption and encapsulation at the interface, so that the dirt is loosened and disintegrated as a whole. The oily dirt partially separated from the surface of the cleaning object is emulsified and dispersed in large quantities by the emulsifier in the cleaning agent, and then brought into the micelle structure, and finally the oily dirt is completely removed from the surface of the cleaning object.

[0026] The special cleaning agent for blackened interior decoration prepared by the present invention has excellent cleaning power, no flash point and is non-flammable. The cleaning agent is non-corrosive to rubber substrates, has little impact on materials after long-term use, and is also low in corrosion to metals. In view of the phenomenon that yellowed interior decorations on the market are difficult to deal with and can only be replaced, this product provides a new cleaning solution. By using this cleaning agent, the use cost of interior decoration parts can be effectively saved, their service life can be extended, and a reliable solution can be provided for long-term cleaning of dirt on the surface of interior decoration parts.

[0027] According to one embodiment of the present invention, the cleaning agent comprises the following components in parts by weight:

[0028] Emulsifier, 10-15 parts;

[0029] Builder, 5-8 parts;

[0030] Penetrant, 5-8 parts;

[0031] Corrosion inhibitor, 3-5 parts;

[0032] Water, 60-75 parts.

[0033] According to an embodiment of the present invention, the emulsifier includes ethylene glycol glucoside, tetradecyl glucoside and alkyl glycoside. The present invention adopts a combination of ethylene glycol glucoside, tetradecyl glucoside and alkyl glycoside, which has a significant synergistic effect and can enhance the emulsification, wetting and detergency of the cleaning agent. Ethylene glycol glucoside, as a mild nonionic surfactant, has good emulsification and solubilization ability, can effectively wrap oily dirt and suspend it in water, and reduce dirt redeposition. Tetradecyl glucoside has stronger surface activity, can significantly reduce the interfacial tension between water and oily dirt, and makes dirt easier to peel off from the surface. In addition, tetradecyl glucoside has excellent wettability, can help the cleaning agent to spread better and penetrate into the depth of the dirt, and further enhance the cleaning effect. Alkyl glycoside (APG0810) is a multifunctional nonionic surfactant, which not only has strong biodegradability, but also is friendly to a variety of surface materials. Its addition can improve the stability of the entire system, especially under different temperature and water conditions, to maintain the high efficiency of the emulsified system. The excellent solubility of alkyl polyglycoside can effectively disperse stubborn dirt, especially in scenarios with low foam requirements. It can reduce the generation of foam, making the cleaning process smoother and facilitating subsequent rinsing. The combination of the three in the cleaning agent can not only enhance the detergency, but also maintain the mildness of the cleaning process and avoid damage to the surface of the cleaned object. The low irritation of ethylene glycol glucoside combined with the environmentally friendly characteristics of alkyl polyglycoside makes the cleaning agent of the present invention more suitable for a variety of application scenarios, including the cleaning of sensitive materials. Through reasonable matching, these three surfactants work synergistically to enable the cleaning agent to have better emulsification, wetting, dispersion and decontamination effects, while maintaining environmental friendliness and biodegradability to meet environmental protection requirements.

[0034] According to one embodiment of the present invention, the emulsifier further comprises the following components: isomeric alcohol polyoxyethylene ether. Isomeric alcohol polyoxyethylene ether can reduce the interfacial tension between water and oil, disperse oily dirt into tiny droplets, and form a stable emulsion. This emulsification helps the cleaning agent to effectively disperse the difficult-to-remove grease pollutants, making them easier to remove from the surface.

[0035] According to one embodiment of the present invention, the builder includes at least one of tea saponin, sodium nitrilotriacetate and disodium EDTA. Both sodium nitrilotriacetate and disodium EDTA have chelating ability, which can effectively chelate hard water ions such as calcium and magnesium in water, avoid insoluble precipitation during cleaning, and ensure the stability and efficiency of the detergent in hard water. Sodium nitrilotriacetate can combine with metal ions faster, improve the decontamination efficiency of the detergent in a shorter time, and disodium EDTA has a wide range of chelating effects on a variety of metal ions, which can further ensure that the residual metal ions in the cleaning system are effectively chelated.

[0036] This combination can minimize the interference of hardness ions in water on the cleaning process and prevent the interaction between hard water ions and components in dirt, thereby improving the overall cleaning effect. In addition, the multifunctional chelating effect of disodium EDTA not only enables it to target common ions in hard water, but also effectively treat some specific metal dirt, such as rust and other metal oxides, expanding the application range of cleaning agents.

[0037] By using the two in combination, the present invention can take into account both the stability of the cleaning agent under a variety of water quality conditions and its wide adaptability to dirt, which not only improves the decontamination effect, but also enhances the reliability and applicability of the cleaning agent, effectively prolongs the duration of the cleaning effect, and reduces the secondary deposition of dirt.

[0038] According to one embodiment of the present invention, the builder further comprises the following components: at least one of sodium metasilicate pentahydrate and sodium silicate.

[0039] According to one embodiment of the present invention, the permeation agent includes at least one of ethanol, diethylene glycol butyl ether and Tween 80.

[0040] According to one embodiment of the present invention, the corrosion inhibitor includes at least one of sodium gluconate, triethanolamine, and sodium tripolyphosphate. The present invention adopts a combination of sodium gluconate and triethanolamine, which can effectively reduce the corrosiveness to the cleaning object while improving the performance of the cleaning agent. Sodium gluconate, as an excellent chelating agent, can chelate with metal ions such as calcium and magnesium in water to prevent these ions from forming insoluble precipitation during the cleaning process, thereby ensuring the stability and efficiency of the cleaning agent. Triethanolamine can also form a protective film with some metal oxides, further reducing the corrosion risk of the metal surface. In addition, the buffering effect of triethanolamine makes the pH of the cleaning agent more stable, which helps to improve the compatibility of the cleaning agent in different application scenarios. The combination of the two, through the combined action of chelation, corrosion inhibition and pH adjustment functions, makes the cleaning agent of the present invention not only have excellent decontamination ability, but also significantly reduce the corrosiveness to the cleaning object, especially when treating metal surfaces, it shows a stronger protective effect. At the same time, this combination can make the cleaning agent suitable for a variety of materials and use environments, further expand its scope of application, and enhance its safety and durability in cleaning.

[0041] According to one embodiment of the present invention, the corrosion inhibitor comprises sodium gluconate and triethanolamine.

[0042] According to one embodiment of the present invention, the corrosion inhibitor further comprises the following components: benzotriazole. The corrosion inhibitor in the present invention adopts benzotriazole, which has a significant anti-corrosion effect, especially on the surface of metal materials. Benzotriazole is an effective metal corrosion inhibitor, especially for copper and its alloys. It can form a stable and dense protective film by chemically reacting with the metal surface, preventing the metal surface from direct contact with oxygen, moisture and corrosive substances, thereby significantly reducing the occurrence of oxidation and corrosion.

[0043] Specifically, the technical solution adopted according to the second aspect of the present invention is:

[0044] A method for preparing the cleaning agent comprises the following steps:

[0045] The emulsifier, the builder, the penetrant and the corrosion inhibitor are mixed in water and stirred to obtain the cleaning agent.

[0046] The cleaning agent prepared by the present invention has excellent cleaning power, no flash point and is non-flammable. The cleaning agent is non-corrosive to rubber substrates, has little impact on materials after long-term use, and is also low in corrosion to metals. In view of the phenomenon that yellowing of interior decorations on the market is difficult to deal with and can only be replaced, this product provides a new cleaning solution. By using the cleaning agent of the present invention, the use cost of interior decoration parts can be effectively saved, their service life can be extended, and a reliable solution can be provided for long-term cleaning of dirt on the surface of interior decoration parts.

[0047] Another aspect of the present invention provides a vehicle interior cleaning agent, including the cleaning agent as described in the first embodiment. Since the application adopts all the technical solutions of the cleaning agent, it has at least all the beneficial effects brought by the technical solutions of the above embodiment.

[0076] Comparative Example 1

[0077] Comparative Example 1 is a commercial cleaning agent, model 3M PN36101 interior cleaning agent.

[0078] Performance Test:

[0079] The cleaning agents of Examples 1-4 and Comparative Example 1 were tested, and the test results are shown in Table 1.

[0080] The detection method is as follows:

[0081] (1) pH value detection: according to GBT 6368 pH value detection method.

[0088] (8) Corrosion test: Refer to GB / T 35759-2017 Metal Cleaning Agent Corrosion Test Method.

[0089] Table 1

[0090]

[0091]

[0092] In Example 2, relative to Example 1, the mass portion of tetradecyl glucoside is increased to 8 parts, the mass portion of alkyl glycoside (APG0810) is reduced to 4.5 parts, and the mass portion of sodium nitrilotriacetate is increased to 6.2 parts, that is, the ratio of the emulsifier is adjusted but the mass of the emulsifier in the system is not changed, and the mass of the builder is improved, which makes the cleaning agent of Example 2 more corrosive to brass and more affects the hardness of chloroprene rubber. This shows that although the cleaning agents prepared in Examples 1-2 have excellent cleaning power and corrosion resistance, after adjusting the ratio of the emulsifier and the mass of the builder, the cleaning agent of Example 2 shows enhanced corrosion to the rubber substrate and the metal, that is, the corrosion resistance of the cleaning agent is slightly reduced.

[0093] Compared with Example 1, Example 3 significantly reduces the mass of the emulsifier and the builder, adjusts the mass of ethylene glycol glucoside to 6 parts, the mass of tetradecyl glucoside to 1.1 parts, and the mass of sodium nitrilotriacetate to 1.2 parts. It can be seen from Table 1 that the cleaning ability of the cleaning agent of Example 3 is reduced compared with that of Example 1. Since the builder in the cleaning agent of the present invention can enhance the adhesion and penetration of the emulsifier on the cleaning surface, when the mass of the emulsifier and the builder is reduced, the encapsulation and adsorption effect of the emulsifier on the dirt will be reduced.

[0094] Compared with Example 1, Example 4 mainly significantly improves the quality of sodium nitrilotriacetate. Although the builder can enhance the adhesion and penetration of the emulsifier on the cleaning surface, it is known from the data in Table 1 that excessive builder will lead to a decrease in the cleaning rate and corrosion resistance of the detergent.

[0095] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention specification, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
