Organosilicon materials are polymers with silicon-oxygen bonds as the main chain and combined with organic functional groups. Their unique molecular structure exhibits multiple advantages: excellent hydrophobicity, good weather resistance, flexibility, and inertness, making them highly promising for a wide range of applications, especially in surface treatment.
Polysiloxanes can be further subdivided into silicone resins, silicone oils, and silicone rubbers based on differences in molecular chains and structures. Silicone oils, due to their lower molecular weight and liquid nature, are particularly suitable for waterproofing textiles. There are many types of silicone oils, including methyl silicone oils, hydrogen-containing silicone oils, hydroxyl silicone oils, and amino silicone oils. These silicone oils each possess their own unique chemical structure and physicochemical properties, exhibiting different application characteristics and finding wide application in various specific fields.
Methyl silicone oil, due to its excellent hydrophobicity and surface activity, is widely used in waterproofing finishing of textiles. The methyl groups in its molecular structure endow it with excellent hydrophobic properties, effectively preventing water penetration. Furthermore, methyl silicone oil also possesses high activity, low surface tension, and easy spreading characteristics, making it suitable for softening fabrics and imparting a certain degree of softness and anti-sticking properties.
Hydrogen-containing silicone oils, on the other hand, are widely used in industrial applications due to their unique chemical reactivity. The silicon-hydrogen bonds in their molecular structure have high reactivity, allowing them to undergo addition reactions with other compounds containing active hydrogen under certain conditions. This characteristic endows materials with entirely new properties.
Modified silicone oils such as hydroxyl silicone oils and amino silicone oils also exhibit excellent properties due to their unique chemical structures. Hydroxyl silicone oils have good hydrophilicity and reactivity, making them key components in the preparation of silicone rubbers and silicone resins with special properties. Amino silicone oils, due to the amino groups in their molecular structure, exhibit good adsorption and reactivity, and are widely used in the preparation of textile finishing agents and plastic modifiers with special properties.
