1,4-二(2-苯硫基苯基)-1,3-丁二炔作为紫外光吸收剂的应用
摘要：
本发明公开了1,4‑二(2‑苯硫基苯基)‑1,3‑丁二炔作为紫外光吸收剂的应用。1,4‑二(2‑苯硫基苯基)‑1,3‑丁二炔具有较好的紫外光吸收性能，能有效吸收270～360nm的紫外光，且吸收紫外线后使得其自身处于激发状态，随后将吸收的能量不是以热量的形式释放，而是以无害的低能辐射释放而回到基态；不仅能够增强紫外光固化涂料及涂层的光稳定性，还具有与树脂或单体相容性好、无气味等特点；还有益于紫外光固化涂料的存储。因此该化合物可作为紫外光吸收剂在光固化组合物如涂料、油墨、黏合剂中应用，也可在塑料或化妆品中应用。
摘要（英）：

The invention discloses application of 1,4-bis(2-thiophenyl phenyl)-1,3-butadiyne as ultraviolet absorber. The 1,4-bis(2-thiophenyl phenyl)-1,3-butadiyne has better ultraviolet absorbing performance and can absorb ultraviolet of 270-360nm, in addition, the 1,4-bis(2-thiophenyl phenyl)-1,3-butadiyne is under an excitation state after absorbing the ultraviolet, then, the absorbed energy is releasedby harmless low-energy radiation to a ground state instead of a heat form. Therefore, the photostability of ultraviolet curing paint and coating can be enhanced, and the 1,4-bis(2-thiophenyl phenyl)-1,3-butadiyne has the characteristics of good compatibility with resin or monomer, no odour and the like, and is favorable for storing the ultraviolet curing paint. Therefore, the compound can be usedas the ultraviolet absorber to be applied in photocuring compounds, including paint, ink and adhesive and also can be applied in plastic or cosmetics.
