闡述了不飽和聚酯膩子的組成及其固化機理。着重讨論了改進不飽和聚酯膩子性能的方法。
聚酯膩子(polyester putty)是一種基于不飽和聚酯樹脂的化學填充材料,主要用于表面修複和造型塑造。其核心成分為聚酯樹脂、滑石粉和苯乙烯單體,通過固化劑(如過氧化甲乙酮)引發交聯反應形成堅硬結構。
該材料在工業與民用領域有廣泛應用:
固化後的聚酯膩子具有以下特性:
需注意操作時需佩戴防護裝備,避免苯乙烯蒸氣吸入。美國職業安全與健康管理局(OSHA)規定工作環境苯乙烯濃度需低于50ppm(來源:OSHA 29 CFR 1910.1000标準)。
以下是關于“polyester”和“putty”的詳細解釋,結合不同場景和用法:
基本定義:
