Etermination of Uv-curable Fluoride Copolymers Synthesis
Abstract:The dodecafluoroheptyl methacrylate was added to the specific proportion of polyurethane acrylate cpua (mass ratio of 1:1 with thinner) and epoxy acrylate UVR6103 blend (mass ratio of 30:70) In this paper．UV curing get good comprehensive properties of coating．First the 2-3% containing acrylate was added in the blend and found that the cured film is easy to fall off，the attachment ability was bad，then the fluorine content down to below 1%，the fluorine content of respectively 0.1%，0.2%，0.3%，0.4%，0.5%，0.6% of 6 groups of experiments．When the resin was cured，the different components were initiated by free radical and cationic initiator．The basic properties of the coating film were tested by IR，TG and SEM，and the surface of the film was determined and the gloss was determined．The comprehensive performance of the film with 0.3% content of fluorine．In the experiment，the best proportion is selected，and the overall performance of film was not affected．In a word，the best fluoride content was 0.3% to the performance of film．

紫外光固化含氟共聚物的合成研究
引 言
涂料领域已经有近200年的发展历史，近年来人们对涂料的要求较高。为了满足人们日常的生产生活需求，涂料领域朝着低(无)污染、高性能的趋势发展[1]。涂料的固化方式有光固化和热固化两种。传统的涂膜固化时大多采用热固化，而较少采用紫外光固化简称UV固化[2]。传统的涂膜固化技术，具有固化时间较长、能耗较大等一系列缺点[3]。紫外光固化技术与传统的固化技术相比，具有固化时间短、生产效率高、省时降耗等优点，研究价值较高[3]。同时由于具有储运更方便、易于清洗设备、不易燃烧和安全性高(大大减少火灾隐患)等诸多优点，是20世纪70年代以来国际上开发出的一种全新的绿色技术[4,5]。因此紫外光固化技术在现在的树脂固化成膜技术中被较多使用。UV固化技术依据所选取的引发剂的不同可以分为自由基光固化，阳离子光固化和阴离子光固化三种固化方式，目前大多以自由基固化和阳离子光固化为主[6]。
