Description

Technical Field

[0001] The invention relates to the technical field of surfactants, in particular to a low-foaming surfactant composition and a production method thereof. Background Art

[0002] The main functions of surfactants include emulsification, dispersion, foaming, solubilization, washing and wetting. Surfactants can reduce the interfacial tension between two immiscible liquids, so that one liquid is evenly dispersed in the other liquid in the form of extremely small droplets to form a stable emulsion. This effect is very useful in food processing, medicine, cosmetics and other fields. For example, when making foods such as milk and cream, surfactants can help fat globules to be evenly distributed in water to form a stable emulsion. Surfactants can make solid particles or droplets evenly distributed in liquids to prevent them from aggregating and precipitating. This effect is very important in the fields of coatings, paints, pigments, etc., which can ensure the uniformity of color and the stability of products. Surfactants can reduce the surface tension of water, so that insoluble gases form stable foam in liquids. This effect is very useful in products such as detergents, shampoos, and foam fire extinguishers. Some water-insoluble substances, such as oils and fats or some drugs, have very low solubility in water. After adding surfactants, the solubility of these substances will be greatly increased to form a transparent solution. This effect is particularly important in pharmaceutical preparations and cosmetics, as it can help improve the bioavailability of drugs and the stability of products. The wetting, penetration, emulsification, dispersion and foaming effects of surfactants are combined to form a washing effect, which is very important in products such as detergents and laundry detergents and can help remove stains and grease. Surfactants can reduce the surface tension of solid surfaces, making it easier for liquids to spread on solid surfaces. This effect is very important in industries such as paint and printing, as it can improve the wettability and adhesion of coatings. In addition, the molecular structure of surfactants is amphiphilic, with a hydrophilic group at one end and a hydrophobic group at the other. This special molecular structure gives surfactants the multiple functions mentioned above.

[0003] Comparative document, application number CN201610363576.3, the present invention provides a surfactant compound composition and its preparation method and application, belonging to the field of chemical additives for oil fields. The surfactant compound composition, based on the total mass of the raw materials as 100%, includes 0.3wt%-2wt% of anionic-nonionic surfactants, 0.05wt%-0.5wt% of amine surfactants, 0.01wt%-2wt% of high molecular polymers, and the balance of water. The surfactant compound composition provided by the present invention has low concentration, small dosage, and a solution pH value close to neutral. It is harmless to the formation and non-corrosive to equipment and pipelines; when the oil saturation is 50%, it still has more than five times the foaming volume, the foam is continuously stable for more than 360 minutes under normal temperature conditions, and the foam half-life can reach 80 minutes at a reservoir temperature of 55°C, which is suitable for foam flooding of high-temperature and high-salinity reservoirs.

[0004] The comparative document, application number is CN202310284812.2, the present invention discloses a low foaming surfactant and a preparation method thereof, which is composed of the following components in weight proportion: 10-20 parts of isooctyl alcohol, 10-20 parts of ethoxylated fatty acid methyl ester, 5-20 parts of phospholipids, 15-23 parts of choline, 20-30 parts of alkylbenzene sulfonate, 5-10 parts of alkyl phosphate monoester salt, 5-10 parts of alkyl phosphate diester salt and 0-3 parts of fragrance, and the remainder is added with a PH regulator to adjust the pH value between 7.5-8.5. The mixing of isooctyl alcohol and ethoxylated fatty acid methyl ester can effectively reduce the foaming property of the surfactant, and the alkyl phosphate monoester salt and the alkyl phosphate diester salt cooperate with each other to achieve reduced bubble performance and superior detergency. And the addition of fragrance can further improve the fragrance of the surfactant, thereby improving the applicability of the surfactant.

[0005] However, the above surfactants have the following disadvantages:

[0006] Although the above-mentioned surfactants are added with low-foaming materials and surfactants generally have foaming properties, this foaming property contributes to their application in daily chemicals such as toothpaste, shower gel, laundry detergent, shampoo and other fields. However, in many industrial fields, especially in the field of high-tech material development, or in zero-emission industrial production of water recycling, this foam can bring fatal harm, resulting in the deterioration of the application performance of the material, or the interruption of the production and processing of the material due to the foam, or the foam causing the pollution of the material production process water, thereby increasing the burden of sewage treatment.
