Description

Technical Field

[0001] The invention relates to organosilicon and a preparation method thereof, belonging to the technical field of organosilicon modification. Background Art

[0002] Organic silicon compounds have Si-O-Si as the main chain and are connected with different organic functional groups. Therefore, they have both organic and inorganic characteristics, and have many unique properties. They have been widely used in many different fields, such as aerospace, electronics, medicine, construction and textiles. Among them, polydimethylsiloxane containing polyether groups in the side chain or end group is called polyether-modified silicone oil. The introduction of polyether segments can not only improve the water solubility of silicone oil, but also increase the hygroscopicity, antistatic properties and easy decontamination of the treated fibers or fabrics. However, most of the traditional polyether-modified silicone synthesis uses toluene as a solvent, which not only increases production costs and reduces production efficiency, but also easily causes environmental pollution and safety hazards. Therefore, the solvent-free green synthesis of polyether-modified silicone is an important development trend in the future, and predecessors have conducted in-depth research on the synthesis and related applications of pure polyether-modified silicone, but there are few reports on functionalized water-based silicone. Functionalized water-based silicone combines the safety and environmental protection characteristics of water-based silicone with the advantages of high reactivity of functionalized silicone. It has important application value and broad market prospects. Summary of the invention
