技术领域
本发明属于涂层技术领域，具体涉及一种增韧加硬涂料组合物、制备方法及塑料处理方法。
背景技术
光学塑料是指用作光学介质材料的塑料，主要用于批量较大的光学仪器中，用于制造光学基板、透镜、隐形眼镜等。聚碳酸酯是一种重要的光学塑料，英文名称polycarbonate，简称PC，是一种分子主链上含有碳酸酯键结构的热塑性树脂，具有透明度高、耐冲击性好、耐热、耐寒、尺寸稳定且透光率高等优点，已成为一种重要的光学材料。但是PC材料表面硬度偏低(铅笔硬度，1kg力，6B)、耐磨性差，易磨损。因此，在光学应用领域需要对其进行表面硬化处理，以提高其硬度和耐磨性，最常用的方法就是涂覆耐磨增硬涂层，其中应用最多的是有机硅体系的耐磨增硬涂层。
公开号CN1752165A公开了一种有机硅透明耐磨增硬涂料及其制备方法，由四烷氧基硅烷、三烷氧基硅烷和二烷氧基硅烷组成的混合物经过酸化水解后，再添加偶联剂，熟化后加入固化剂和固化促进剂，可以在PC表面获得透明、硬度达3H以上的涂层。
公开号CN1834180A公开了一种用于光学塑料表面增强的有机硅耐磨透明涂料，包括体积比83.3～86.7％：13.3％～16.7％的A、B两组分，A组分含有体积比为25～31％的有机硅单体，0.2～1％的流平剂，68～74.6％的溶剂；B组分含有重量百分比6.2～9.9％的浓盐酸，89.7～93.1％的水，0.4～1.1％的固化剂。有机硅单体由正硅酸乙酯、甲基三甲氧基硅烷、γ-缩水甘油醚氧丙基三甲氧基硅烷、γ-甲基丙烯酰氧丙基三甲氧基硅烷组成。
