AI Technical Summary
Technical Problem
Existing nano-SiO2 modifiers have poor antifouling effects in marine coatings, especially in their inability to effectively inhibit algae growth. Furthermore, the modifiers are incompatible with the resins, which affects the coating performance.
Method used
Antifouling agent modified nano-silica superhydrophobic filler was prepared by modifying nano-silica particles with low surface energy fluorinated silane coupling agent and thymol antifouling agent via sol-gel method.
Benefits of technology
The prepared nano-silica particles have good antifouling and hydrophobic properties, can effectively inhibit algae growth, are suitable for ship antifouling, and the preparation method is simple and easy to implement.

Abstract
本发明提供了一种防污剂改性纳米二氧化硅超疏水填料，包括：将防污剂百里酚与含异氰酸根的硅烷偶联剂反应，得到百里酚改性化合物；将百里酚改性化合物、含氟硅烷偶联剂与硅酸乙酯、氨水、乙醇混合，通过溶胶‑凝胶法，在二氧化硅纳米颗粒成型过程中对二氧化硅纳米颗粒进行改性，得到百里酚改性纳米二氧化硅超疏水填料。所制备纳米填料以低表面能含氟硅烷偶联剂和百里酚防污剂为改性剂，通过溶胶‑凝胶法得到具有超疏水特性和防污特性的改性纳米SiO2颗粒。产物不但具有良好的防污及疏水性能，而且制备方法简单易于合成，有效的抑制藻类生长，适用于船舶防污。
