Abstract
本發明關於一種矽氫化可固化聚矽氧組成物,其包含:順丁烯二酸酯化合物、及該順丁烯二酸酯化合物以外之矽氫化抑制劑,其中分別相對於本發明組成物以質量單位計,該順丁烯二酸酯化合物之含量係在50至6,000 ppm的量,並且該矽氫化抑制劑之含量係在200至20,000 ppm的量。該矽氫化可固化聚矽氧組成物展現出良好的儲存穩定性,並且可固化形成沒有表面起皺的固化產物。
Description
本發明關於一種矽氫化可固化聚矽氧組成物。
矽氫化可固化聚矽氧組成物會形成具有優異特性(諸如耐候性及耐熱性)的固化產物,且其等藉由加熱會特別快速地固化,而不會在固化時產生副產物,因此這些組成物會用來密封、覆蓋、或黏著光學半導體裝置中之光學半導體元件。眾所皆知,加入至少一種矽氫化加成抑制劑以調整組成物的可固化性及儲存穩定性。然而,降低固化溫度及縮短固化時間會導致組成物的儲存穩定性明顯劣化,並且低溫固化會促進固化產物的表面起皺。為解決此類問題,提出了一些可固化聚矽氧組成物。
此類可固化聚矽氧組成物的實例包括可固化聚矽氧組成物,該組成物包含:含烯基之有機聚矽氧烷、有機氫聚矽氧烷、矽氫化催化劑、及醯胺化合物(參見專利文件1);可固化聚矽氧組成物,該組成物包含:每分子具有至少二個烯基之有機聚矽氧烷、每分子具有至少二個矽鍵結氫原子之有機氫聚矽氧烷、基於鉑族金屬之催化劑;及二氫二矽烷化合物(參見專利文件2);及可固化聚矽氧組成物,該組成物包含:每分子具有至少一個矽鍵結烯基之有機聚矽氧烷、每分子具有在分子鏈末端之至少一個矽鍵結氫原子、在非分子鏈末端之至少二個矽鍵結氫原子的有機氫聚矽氧烷、及矽氫化催化劑(參見專利文件3)。
然而,在相對低的溫度下固化,難以一致地達到良好可固化性與防止固化表面起皺。 先前技術文件 專利文件
專利文件1:日本專利申請案公開第平08-183908 A號 專利文件2:日本專利申請案公開第2001-26716 A號 專利文件3:美國專利申請案公開第2005/0272893 A1號
技術問題 本發明之目的係提供一種矽氫化可固化聚矽氧組成物,其展現出良好儲存穩定性,且可固化形成沒有表面起皺的固化產物。 問題之解決方案
本發明之矽氫化可固化聚矽氧組成物的特徵在於包含:順丁烯二酸酯化合物、及該順丁烯二酸酯化合物以外之矽氫化抑制劑,其中分別相對於該組成物以質量單位計,該順丁烯二酸酯化合物之含量係在50至6,000 ppm的量,而該矽氫化抑制劑之含量係在200至20,000 ppm的量。
本發明之矽氫化可固化聚矽氧組成物較佳地包含: (A) 每分子具有至少二個烯基之有機聚矽氧烷; (B) 每分子具有至少二個矽鍵結氫原子之有機氫聚矽氧烷,其量會使得相對於1莫耳的組分(A)中之烯基提供0.1至10.0莫耳的矽鍵結氫原子; (C) 矽氫化催化劑,其量足以加速該組成物之固化; (D) 順丁烯二酸酯化合物,其量相對於該組成物以質量單位計係50至6,000 ppm;及 (E) 該順丁烯二酸酯化合物以外之矽氫化抑制劑,其量相對於該組成物以質量單位計係200至20,000 ppm。

本發明組成物亦可包含(G)含鈰之有機聚矽氧烷,以抑制由於藉由固化本發明組成物所獲得固化產物中之熱老化所導致的裂紋。此類組分(G)例如係藉由與氯化鈰或羧酸之鈰鹽及含矽醇之有機聚矽氧烷的鹼金屬鹽之反應來製備。
