Description

Technical Field

[0001] The present invention belongs to the field of cleaning technology, in particular to the field of C11D1 / 00, and more specifically relates to an automobile glass oil film remover and a preparation method thereof. Background Art

[0002] With technological advancements and economic development, automobiles have become a widespread part of daily life. While driving or after prolonged parking, various stubborn and difficult-to-remove dirt and oil films can form on the surface of car glass. These deposits are primarily caused by exhaust from preceding vehicles, urban smoke, tree sap, shellac, insect carcasses, bird droppings, and condensation from industrial waste gas. If these deposits are not promptly removed, they not only degrade the car's aesthetic appearance, but excessive accumulation can also impair the driver's visibility, seriously endangering the lives of both the driver and passersby. Therefore, a novel oil film remover that can effectively remove oil film from car glass without causing corrosive damage and remaining safe for human consumption holds great market potential.

[0003] Prior art CN105132222A discloses a low-surface-tension automotive oil film remover. The low-surface-tension activated water used in this invention can fully wet the glass surface, remove more stains, and reduce the use of surfactants and their environmental pollution. It offers excellent properties such as energy conservation and environmental protection, a long shelf life, strong decontamination ability, and excellent anti-fog and anti-frost properties. However, the lack of an abrasive in the oil film remover makes it difficult to completely remove some stubborn solid stains on automotive glass.

[0004] Prior art CN200420084593.6 discloses a cleaning bag for automotive windshield oil film. This cleaning bag is soft, breathable, and water-absorbent. The bag contains inorganic abrasive powder, which can be wetted and wiped to remove oil film and dirt from automotive windshields, maintaining glass clarity and safe driving vision while preventing windshield wiper vibration and noise. The bag is easy to carry and offers excellent cleaning effectiveness. However, the abrasive particles are unevenly dispersed in water, forming aggregates that can easily scratch the automotive glass surface, shortening its service life. Summary of the Invention

[0005] In order to solve the above problems, the first aspect of the present invention provides an automobile glass oil film remover, the raw materials for preparing the same include the following components: abrasive, surfactant, solvent, thickener, alkali, and glass water additive.

[0006] Further preferably, the raw materials for preparation include, by weight, 5-15 parts of abrasive, 2-8 parts of surfactant, 150-200 parts of solvent, 1-5 parts of thickener, 1-5 parts of alkali, and 1-5 parts of glass water additive.

[0007] Further preferably, the raw materials for preparation include, by weight, 8 parts of abrasive, 6 parts of surfactant, 180 parts of solvent, 4 parts of thickener, 4 parts of alkali, and 3 parts of glass water additive.

[0008] Preferably, the abrasive includes at least one or more of corundum, silicon carbide, diatomaceous earth, aluminum oxide, boron carbide, silicon dioxide, artificial diamond, iron oxide, chromium oxide, and cerium oxide.

[0009] More preferably, the abrasive comprises diatomaceous earth, boron carbide, and cerium oxide.

[0010] More preferably, the mass ratio of the diatomaceous earth, boron carbide and cerium oxide is (1-5): (1-3): (0.8-2).

[0011] Further preferably, the mass ratio of the diatomaceous earth, boron carbide and cerium oxide is 3:2:1.

[0012] The inventors have discovered that when boron carbide and cerium oxide are used in combination, they can effectively work synergistically to remove oil film dirt from automobile surfaces. However, the spherical particles of boron carbide and cerium oxide may have sharp edges and corners, which may cause scratches on the automobile glass surface during use. Therefore, adding a certain amount of diatomaceous earth to the grinding aid can not only further improve the decontamination effect of the oil film remover, but also the diatomaceous earth can coat the edges and corners of the boron carbide and cerium oxide particles, reducing damage to the automobile glass surface caused by the boron carbide and cerium oxide particles in the abrasive, thereby increasing safety in use.

[0013] Preferably, the surfactant includes at least one or more of anionic surfactants, cationic surfactants, and nonionic surfactants.

[0014] More preferably, the surfactant includes anionic surfactant and nonionic surfactant.

[0015] Preferably, the anionic surfactant includes at least one or more of sodium lauryl polyether sulfate, sodium lauryl sulfate, ammonium lauryl sulfate, N-acyl amino acid salt, sulfoaryl sulfonate, sodium lauryl alcohol polyoxyethylene ether sulfate, and sodium hexadecyl polyoxyacetate.

[0016] More preferably, the anionic surfactant is sodium lauryl sulfate.

[0017] Preferably, the nonionic surfactant includes at least one or more of N,N-diethyl-2-chloroacetamide, polyoxyethylene fatty alcohol ether, and glyceryl monostearate.

[0018] More preferably, the nonionic surfactant is N,N-diethyl-2-chloroacetamide.

[0019] Preferably, the mass ratio of the anionic surfactant to the nonionic surfactant is (5-10):(3-5).

[0020] Further preferably, the mass ratio of the anionic surfactant to the nonionic surfactant is 6:4.

[0021] The inventors have discovered that the anionic surfactant sodium lauryl sulfate can be adsorbed on the nonionic surfactant N,N-diethyl-2-chloroacetamide, reducing the repulsion between like charges on the surface of the oil film remover solution. There is also a certain hydrophobic interaction between the hydrophobic groups and the hydrocarbon chains of the two, which makes the surfactant molecules more densely arranged in the system, thereby having higher surface activity. Sodium lauryl sulfate can form mixed micelles with N,N-diethyl-2-chloroacetamide, reducing the electrostatic repulsion between surfactants, promoting micelle formation, and enhancing the decontamination ability of the oil film remover.

[0022] Preferably, the solvent includes deionized water and ethanol.

[0023] Further preferably, the mass ratio of deionized water to ethanol is (6-10):(2-5).

[0024] Further preferably, the mass ratio of the deionized water to the ethanol is 9:3.

[0025] Preferably, the thickener includes at least one or more of an ionic thickener and a non-ionic thickener.

[0026] More preferably, the thickener is an ionic thickener.

[0027] More preferably, the ionic thickener is hydroxypropyl methylcellulose.

[0028] The inventors discovered that when the thickener is the ionic thickener hydroxypropyl methylcellulose, it affects the micellar diffusion double-layer structure of the surfactant in the system, thinning the double layer thickness and lowering the surfactant's critical micelle concentration, thereby improving the surfactant's emulsification and enhancing the stability of the oil film remover. However, if added in excessive amounts, the surfactant's hydrophilic groups will curl up, losing their hydrophilic properties, reducing the surfactant's solubility and even forming precipitation.

[0029] Preferably, the alkali includes at least one or more of sodium hydroxide, potassium hydroxide, sodium bicarbonate, and sodium citrate.

[0030] More preferably, the base is sodium citrate.

[0031] Preferably, the glass water additive includes at least a preservative, a flavor, and a pigment.

[0032] Further preferably, the mass ratio of the preservative, flavor and pigment is 1:1:1.

[0033] A second aspect of the present invention provides a method for preparing an automobile glass oil film remover, comprising at least the following steps:

[0034] S1. Mix the solvent, surfactant, thickener and glass water additive at a certain temperature;

[0035] S2, adding alkali to the mixed solution prepared in step S1 and adjusting to a suitable pH;

[0036] S3. Add the abrasive to the mixed solution obtained in step S2, mix and stir, and obtain the oil film remover.

[0037] Preferably, the temperature in step S1 is 30-50°C; the pH value in step S2 is 7.5-9.0; the stirring speed in step S3 is 500-800 rpm, the stirring time is 20-40 min, and the stirring temperature is 20-30°C.

[0038] Further preferably, the temperature in step S1 is 40°C; the pH value in step S2 is 8.0; the stirring speed in step S3 is 600 rpm, the stirring time is 30 min, and the stirring temperature is 25°C.

[0039] Beneficial effects

[0040] (1) In the present invention, by compounding diatomaceous earth, boron carbide and cerium oxide and using them as abrasives, not only the cleaning effect of the oil film remover is effectively improved, but also damages and scratches the surface of automobile glass will not be caused, thereby improving the safety of use.

[0041] (2) In the present invention, when the surfactant is a mixture of anionic surfactant and nonionic surfactant, the surfactant molecules are arranged more closely in the system, thereby having higher surface activity and better detergency.

[0042] (3) In the present invention, when the thickener selected is the ionic thickener hydroxypropyl methylcellulose, it not only improves the emulsification effect of the surfactant, but also enhances the stability and detergency of the oil film remover.

[0043] (4) The oil film remover prepared in the present invention is environmentally friendly and pollution-free, does not cause harm to the human body and the environment, and is safe and convenient to use.

[0044] (5) The preparation method of the oil film remover of the present invention is simple. It only requires mixing and stirring the materials in a certain order at a relatively low temperature, which will not destroy the activity of the oil film remover. In addition, the raw materials for preparation are easily available and inexpensive, making it suitable for large-scale production. DETAILED DESCRIPTION
