一种功能涂料的制备方法
摘要：
本发明公开了一种功能涂料的制备方法，该涂料能在塑料、金属和陶瓷等基材的表面形成功能性涂层。本发明中所述的涂料由双(三烷氧基)硅烷偶联剂与其他单(三烷氧基)硅烷偶联剂的组合物组成，其中双(三烷氧基)硅烷偶联剂与单(三烷氧基)硅烷偶联剂的比例为摩尔比6:1～1:1，在溶剂中配制成质量浓度为2％～10％的溶液。经过2～6小时的水解反应，涂覆在基材表面形成硅氧烷的涂膜，经60～120℃烘干交联后，形成一层均匀平整的涂层。该涂料提供一种具有所需表面能及耐溶剂腐蚀的涂层，可以实现对金属、无机非金属和有机聚合物基材表面的功能化。
摘要（英）：

The invention discloses a preparation method of a functional coating. The coating can form a functional coating layer on the surface of a base material like plastic or metal or ceramic. The coating is composed of a composition of a bis(trimethylsilyl) silane coupling agent and other mono(trimethylsilyl) silane coupling agents, wherein the molar ratio of the bis(trimethylsilyl) silane coupling agent to the mono(trimethylsilyl) silane coupling agents is 6:1-1:1; a solution with the mass concentration of 2%-10% is prepared in a solvent; after a hydrolysis reaction lasting for 2 h-6 h, the surface of the base material is coated with the solution to form a siloxane coating film, and after drying and crosslinking at the temperature of 60 DEG C-120 DEG C, the uniform and flat coating layer is formed. The coating can form the coating layer with the surface resistant to solvent corrosion resistance and achieve functionalization for the surface of a base material like metal or inorganic nonmetal or an organic polymer.
