一种改性嵌段硅油及其制备方法、应用
By using a modified block silicone oil preparation method, isopentenyl alcohol polyoxyethylene ether segments are grafted onto the silicone oil backbone to generate a block-structured modified silicone oil, which is used for waterborne acrylate emulsion polymerization. This solves the problem of insufficient antifouling performance of waterborne acrylate coatings and achieves a long-lasting hydrophobic and oleophobic effect.

AI Technical Summary
Existing waterborne acrylic coatings perform poorly in terms of stain resistance, anti-blocking properties, and water resistance. Furthermore, silicone modification technology suffers from high costs, poor compatibility, and low modification efficiency, making it difficult to achieve a long-lasting dual-repellent antifouling effect.
Modified block silicone oil is used by covalently grafting multiple isopentenyl alcohol polyoxyethylene ether segments onto the silicone oil backbone to generate a block structure with free radical polymerizable double bonds. This structure is used for waterborne acrylate emulsion polymerization to form a low surface energy layer to achieve hydrophobic and oleophobic effects.
It achieves durable hydrophobic, oleophobic, and antifouling properties of waterborne acrylic coatings, reduces the surface energy of the paint film, improves stain resistance and anti-blocking properties, and avoids the environmental risks of organic fluorine.
