From a chemical point of view, the carboxyl group in carboxyl silicone oil emulsion has a certain acidity and can react with alkali to neutralize. This characteristic makes carboxyl silicone oil emulsion uniquely applicable in some systems that require pH adjustment. For example, in some water-based coating systems, carboxyl silicone oil emulsion can be used as a film-forming aid to form a paint film with good performance by reacting with the alkali in the system. This paint film has good adhesion, water resistance and chemical corrosion resistance, and can meet the use requirements in different environments.


In terms of fabric treatment, carboxyl silicone oil emulsion also has important applications. It can react with amino, hydroxyl and other groups on fabric fibers to form chemical bonds, thereby improving the softness, hygroscopicity and antistatic properties of the fabric. Compared with other types of silicone oil emulsions, fabrics treated with carboxyl silicone oil emulsion have better hydrophilicity, can quickly absorb moisture, and make the wearer feel more comfortable. At the same time, its antistatic properties can also effectively reduce the static electricity generated by fabrics during wearing and use, and improve the quality and safety of fabrics.


In the leather industry, carboxyl silicone oil emulsion can be used for leather softening and waterproofing. It can penetrate between leather fibers, fill the gaps, and make the leather soft and plump. At the same time, carboxyl silicone oil emulsion can also form a waterproof film on the surface of the leather to prevent water penetration and improve the waterproof performance and durability of the leather. Leather treated with carboxyl silicone oil emulsion not only feels good, but also has better anti-fouling properties and is easy to clean and maintain.


In addition, carboxyl silicone oil emulsion is also used in the papermaking industry. It can be used as a softener and sizing agent for paper to improve the softness, strength and water resistance of paper. In the production process of paper, adding an appropriate amount of carboxyl silicone oil emulsion can make the paper surface smoother, reduce friction between papers, and improve the printing adaptability of paper.


With its unique chemical properties and excellent performance in many fields, carboxyl silicone oil emulsion has provided important support for the development of related industries. With the continuous deepening of its performance research and the continuous innovation of application technology, the application prospects of carboxyl silicone oil emulsion will be broader.
