氟碳树脂的合成及有机硅改性

以偶氮二异丁腈为引发剂，甲基异丁基甲酮为溶剂，将氟碳单体与甲基丙烯酸甲酯、丙烯酸乙酯、丙烯酸丁酯等单体进行溶液聚合得到氟碳树脂共聚物。当氟碳单体质量分数较低(5％)时，加入质量分数为2％～8％的有机硅烷偶联剂单体，制得有机硅改性氟碳树脂共聚物。性能测试结果表明：该有机硅改性共聚物具有硬度高、耐水、耐碱、耐溶剂、表面自洁及耐沾污等优良性能。有机硅改性不但提高了氟碳树脂的性能，而且降低了成本，为其工业化生产和制备有机硅改性全氟碳涂料创造了条件。

Synthesis and organosilicon modification of fluorocarbon resin

This paper synthesized fluorocarbon resin copolymer via solution polymerization of fluorocarbon monomer with methyl methacrylate, ethyl acrylate and butyl acrylate, taking azodiisobutyronitrile as initiator and methyl isobutyl ketone as solvent. A kind of organosilicon modified fluorocarbon resin was prepared by adding 2% - 8% (mass fraction) organosilicon coupling agent into fluorocarbon monomer that was at a concentration level as low as 5% (mass fraction). The analytical results of properties show that the modified fluorocarbon resin has the features of superior hardness, resistance to water, alkali and solvent, and ability of self-cleaning and anti-fouling. The modification by organosilicon not only raised the properties of fluorocarbon resin, but also reduced the production cost, thereby creating a favourable condition for commercially producing the resin and preparing the organosilicon modified fluorocarbon resin coating.
