摘要: 以异佛尔酮-二异氰酸酯(IPDI)、聚四氢呋喃1000(PTMEG-1000)、聚乙二醇400(PEG-400)、甲基丙烯酸-β-羟乙酯(HEMA)为基本原料,合成了一类丙烯酸酯类聚氨酯大单体,然后用偶氮二异丁腈(AIBN)引发大单体聚合制备了一种高透明性的耐候性聚氨酯(PU)材料.利用FT-IR,XRD对所制备的PU材料进行表征和分析;通过冷冻和紫外光老化处理实验,研究了PU材料的耐候性.结果表明,PTMEG-1000含量的增加能显著提高PU材料的光学性能和热稳定性,PU材料在冷冻和紫外光照射条件下,综合性能与常温下相差不大,表明其具有良好的耐候性.其中PU-3材料的综合性能较佳,其常温下透光率为92.1%,拉伸强度为13.1 MPa;在-26℃下透光率为84.7%,拉伸强度为15.7 MPa;经紫外光辐射后其透光率为74.3%,拉伸强度为11.5 MPa.

Abstract: Poly (urethane-methacrylate) macromonomers were synthesized based on isophorone diisocyanate (IPDI), poly (tetrahydrofuran) 1000 (PTMEG-1000), poly (ethylene glycol) 400 (PEG-400) and β-hydroxyethyl methacrylate (HEMA). Then high transparent poly (urethane-methacrylate) materials with weathering resistance were prepared by the polymerization of the macromonomers using 2,2-azo-bis-iso-butyro-nitrile (AIBN) as initiator. The obtained PU materials were characterized by FT-IR and XRD.The weathering resistance of PU materials was characterized under the condition of freezing and UV-irradiation. The results showed that the thermal stability and optical performance of PU materials increased with increasing PTMEG-1000 content, and comprehensive performance in freezing and UV-irradiation conditions were almost the same results as at room temperature, which indicated the materials owned good weatherability. PU-3 exhibited outstanding performance. The tensile strength and the transmittance of PU-3 were 13.1 MPa and 92.1% at room temperature, respectively. Its tensile strength and transmittance were 15.7 MPa and 84.7% at -26℃, respectively. And its tensile strength and transmittance were 11.5 MPa and 74.3% after UV-irradiation, respectively.
