Description
Technical Field
The invention belongs to the technical field of chemical cleaning agents, and particularly relates to an alkaline multifunctional cleaning agent, a preparation method and application thereof.
Background
With the improvement of the quality of life, attention is paid to all aspects of cleaning, and the performance of the cleaning agent directly influences the cleaning effect and the use quality of appliances. Meanwhile, the application range of the cleaning agent is gradually expanded, and the cleaning agent is used for cleaning various oil stains, oil greases such as plastic, optical glass lenses, metal products (copper, iron, aluminum, steel and alloy) and the like in the industrial industry from the traditional method for cleaning clothes, furniture and appliances to the cleaning of various oil stains and oil greases such as cutting oil, antirust oil, lubricating oil and stamping oil. Therefore, the demand for detergents has been increasing, and there is a demand for detergents which are not only strong in detergency but also green and environmentally friendly, do not damage the skin, and have high antibacterial properties.
At present, the cleaning agent is mainly divided into an acidic cleaning agent and an alkaline cleaning agent, wherein the acidic cleaning agent has the functions of sterilization and deodorization and can remove alkaline stubborn stains and dirt; alkaline cleaners remove some greasy soils and acidic soils. The alkaline cleaning agent is mainly compounded by a surfactant and other raw materials; the acidic cleaning agent is a detergent prepared by mixing and dissolving amines and additives serving as raw materials. The pH value of the acidic cleaning agent is higher, and generally the pH value is less than 7, so that the acidic cleaning agent has certain damage to human skin. Therefore, the alkaline cleaning agent has relatively better use safety, and the oil removing mechanism of the alkaline cleaning agent is as follows: saponification: animal and vegetable oil (main component is stearic acid) in the metal surface grease is dissolved into alkaline solution with sodium stearate (namely soap) and glycerin generated by alkali in the alkaline cleaning agent, and the saponification reaction is commonly called to remove the metal surface grease; emulsification: the emulsifier is surface active matter adsorbed on the interface, the hydrophobic radical is toward the metal matrix and the hydrophilic radical is in the direction of solution to reduce the interfacial tension between metal and solution, so that under the action of fluid power and other factors, the oil film is broken into fine bead and separated from the metal surface to form emulsion in the solution. Saponification and emulsification are complementary and can be matched with each other to completely remove oil stains on the metal surface; soaking and wetting effects: the saponification and emulsification are performed from the surface of oil dirt, so that the alkaline solution containing alkaline agent is soaked into the oil dirt to wet the surface of workpiece and raise the degreasing and oil-removing effect. In addition, the grease dispersing agent still has a dispersing effect, and grease removed from a workpiece is dispersed into a solution.
Chinese patent application 202010786734.2 discloses a paste-like dish detergent prepared from the following raw materials: the raw materials comprise the following components in parts by weight: sodium fatty alcohol polyoxyethylene ether sulfate: 34-35 parts of dodecyl benzene sulfonic acid: 3-10 parts of coconut diethanolamide: 5-7 parts of sodium hydroxide or ammonium hydroxide: 0.3-1.52 parts, sodium chloride or ammonium chloride: 23-25 parts of kasong: 0.84-0.86 parts of fatty alcohol polyoxyethylene (9) ether: 1.5-2.5 parts of alpha-sodium alkenyl sulfonate: 1.9-2.1 parts, cocoamidopropyl betaine: 3.5-4.5 parts of sodium dodecyl sulfate: 0.9-1.1 parts of water: 10-13 parts; the invention changes the liquid state of the liquid tableware detergent into paste state, improves the product concentration, and improves the effective components from 5 to 25 percent to 60 to 90 percent.
