可紫外光固化有机硅丙烯酸酯的合成及性能

摘要

UV- curing organosilicone acrylate was synthesized with DMC and acrylic acid as raw materials. The effects of polymerization inhibitor and water-carrying agent on the synthesis were studied. The mechanical properties, surface energy, curing time and solubility of the UV-curing membrane were determined, and the UV-curing membrane was characterized by infrared spectroscopy(FTIR). The mechanical properties of the UV-curing membrane are good and surface energy is low while it is adjusted by adding different monomers. The UV-curing membrane is insoluble in water and acid solution, but soluble in organic solvents and alkaline solution.%以DMC(二甲基环硅氧烷混合物)和丙烯酸为原料,合成出可紫外光固化的有机硅丙烯酸酯.考察了阻聚剂和带水剂等因素对合成反应的影响,测定了紫外光固化膜的力学性能、表面能、固化时间和溶解性能,通过红外光谱(FTIR)对光固化膜进行了表征.结果表明:光固化膜的力学性能好,表面能低,加入不同的活性单体,可以对膜的表面能进行调节;光固化膜不溶于水和酸溶液,但溶于有机溶剂及碱溶液.
