Description

Technical Field

[0001] The invention belongs to the technical field of glass water formulation, and particularly relates to a multifunctional glass water and a preparation method thereof. Background Art

[0002] In recent years, my country's automotive market has grown rapidly, and the number of consumable materials used in vehicles has also increased year by year. Among these, windshield washer fluid, or windshield cleaning fluid, is undoubtedly one of the most popular consumer products. A high-quality windshield washer fluid not only possesses strong cleaning properties but also excellent wettability, lubricity, antifreeze, corrosion resistance, antistatic properties, and insect repellency. Thus, it maintains a clean and transparent windshield, effectively protecting automotive components.

[0003] However, there are many different types of windshield washer fluids on the market, and their quality varies greatly. Most have limited functionality or are subpar overall performance, making it difficult to effectively clean the windshield while also protecting auto parts and preventing scratches. This can negatively impact the user's driving experience and normal travel, and can even cause traffic accidents.

[0004] In view of the above-mentioned technical problems, the present invention provides a new type of multifunctional automobile windshield washer fluid. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the current glass water and provide a multifunctional glass water and a preparation method thereof.

[0006] To achieve the above objectives, the technical solutions provided by the present invention are as follows:

[0007] A multifunctional glass water, characterized by comprising the following components by mass percentage:

[0008] Ethylene glycol 5%~30%, ethanol 5%~15%, ethylene glycol monobutyl ether 0.5-1%, cocamidopropyl betaine 0.5%~1%, fatty alcohol polyoxyethylene ether carboxylate AEC 0.5%~1%, alkyl polyglycoside APG 0.5%~1%, preservative 0.1%~0.2%, fungicide 0.1%~0.2%, water-soluble pigment 0.03%~0.05%, the balance is deionized water. Of course, other water with better quality than deionized water can also be used, but the cost will increase accordingly.

[0009] The cocamidopropyl betaine, fatty alcohol polyoxyethylene ether carboxylate AEC and alkyl polyglycoside APG are used as surfactants, accounting for 1.5% to 2.5% of the multifunctional glass water.

[0010] Among them, when the use environment is above 0℃, ethylene glycol monobutyl ether is added, which is mainly used for insecticide, especially in the summer when there are more mosquitoes. Ethylene glycol monobutyl ether should be added to multi-purpose glass water;

[0011] When the operating environment is 0℃ or below, add ethylene glycol and use it with ethanol to lower the freezing point and prevent the windshield washer fluid from freezing at low temperatures. Especially in the cold winter, ethylene glycol should be added to the multi-functional windshield washer fluid and used in combination with ethanol.

[0012] Furthermore, in order to enhance the customer experience of using the product, 0.1~0.2% fragrance is also included.

[0013] Furthermore, in order to improve the performance of the product during winter use, 0.25% to 0.5% water softener is also included.

[0014] Furthermore, when the usage environment is above 0°C, especially in the summer formula, 5% ethanol, 0.5% ethylene glycol monobutyl ether, 0.5% cocamidopropyl betaine, 1% fatty alcohol polyoxyethylene ether carboxylate AEC and 0.5% alkyl polyglycoside APG, and other components are appropriately selected according to needs within the aforementioned range.

[0015] Furthermore, when the usage environment is 0°C or below, especially in the winter formula, ethylene glycol 20%, ethanol 10%, cocamidopropyl betaine 0.5%, fatty alcohol polyoxyethylene ether carboxylate AEC 1% and alkyl polyglycoside APG 0.5%, and other components are appropriately selected within the above range as needed.

[0016] Furthermore, the preservative is benzotriazole;

[0017] The bactericide is kason;

[0018] The flavor is lemon flavor;

[0019] The water softener is sodium dihydrogen phosphate;

[0020] The water-soluble pigment is a water-soluble saturated bright blue pigment;

[0021] In addition, other substances that can achieve the corresponding functions can also be selected as substitutes.

[0022] The special feature of the above-mentioned method for preparing multifunctional glass water is that it comprises the following steps:

[0023] 1) Weigh the raw materials by mass percentage, add deionized water, ethylene glycol, and ethanol to a reaction vessel at room temperature, and stir evenly to obtain solution A;

[0024] 2) heating the solution A obtained in step 1) to 35°C to 40°C, then slowly adding the fatty alcohol polyoxyethylene ether carboxylate AEC while stirring. After complete addition, stirring evenly to obtain solution B;

[0025] 3) Add cocamidopropyl betaine, alkyl polysaccharide, and ethylene glycol monobutyl ether to solution B obtained in step 2), stir evenly, then add preservatives, fungicides, flavors, and water-soluble pigments, and stir until transparent and uniform to obtain multifunctional glass water.

[0026] In the above steps, ethylene glycol, ethylene glycol monobutyl ether, water softener and fragrance are added according to the specific usage.

[0027] Furthermore, in order to ensure product production safety and efficiency, in step 1), stirring is performed at a rate of 100-120 r / min for 3-5 minutes to ensure uniform stirring;

[0028] In step 2), after complete addition, continue stirring at a rate of 150-180 rpm for 10-15 minutes until evenly mixed.

[0029] In step 3), after adding cocamidopropyl betaine, alkyl polysaccharide, and ethylene glycol monobutyl ether, stirring at a rate of 150-180 r / min for 5-10 minutes; after adding corrosion inhibitor, preservative, flavor, and water-soluble pigment, stirring at a rate of 150-180 r / min for 5-10 minutes.

[0030] The advantages of the present invention are:

[0031] The glass water formula of the present invention incorporates multiple surfactants, including fatty alcohol polyoxyethylene ether carboxylate (AEC), the multifunctional zwitterionic surfactant cocamidopropyl betaine, and the nonionic surfactant alkyl polyglycoside (APG). The different types of surfactants form a complex system with multiple intermolecular interactions. Appropriate compounding can produce synergistic effects between the components, exhibiting complex self-organizing behavior and superior performance compared to a single system. Furthermore, the system exhibits good stability and can significantly improve the various properties of the glass water. Specifically:

[0032] 1. The molecules of fatty alcohol polyoxyethylene ether carboxylate AEC in the surfactant of the present invention can be adsorbed on the surface of the stain and form a double electric layer that can diffuse freely. Since like charges repel each other, the adhesion of the stain on the glass surface is reduced, thereby effectively removing glass stains.

[0033] 2. The carboxylic acid in the fatty alcohol polyoxyethylene ether carboxylate (AEC) surfactant of this invention can undergo an esterification reaction with alcohol, producing a lubricating grease that effectively reduces friction between the wipers and the glass, preventing scratches. Furthermore, the combination of ethanol and ethylene glycol can effectively lower the freezing point, especially in winter. The use of ethanol can make windshield washer fluid more volatile, making it more convenient to use.

[0034] 3. The compound system of fatty alcohol polyoxyethylene ether carboxylate AEC, nonionic surfactant alkyl polyglycoside APG and amphoteric surfactant cocamidopropyl betaine in the present invention enables the glass water to have better cleaning, wetting, anti-fog and anti-static effects, and still has good stability under low temperature conditions, showing better performance than a single system. At the same time, it has good stability, can significantly improve the various properties of glass water, effectively remove stains, protect auto parts, and escort the safe travel of the majority of car users.
