    • PURPOSE: Provided is a rubber composition for engine mount comprising 5-10 parts by weight of 1,2-polybutadiene and 1-2 parts by weight of tris(mono-nonylphenyl)phosphate with respect to 100 parts by weight of raw rubber, thereby improving heat resistance and minimizing permanent deformation by adding a co-agent and an aging preventer. CONSTITUTION: The rubber composition for engine mount comprises 5-10 parts by weight of 1,2-polybutadiene and 1-2 parts by weight of tris(mono-nonylphenyl)phosphate with respect to 100 parts by weight of raw rubber. The rubber composition comprises 1-1.5 parts by weight of sulfur, 0.5-1 parts by weight of tetramethylthiuramdisulfide, and 0.2-0.5 parts by weight of N-cyclohexyl-2-benzothiazylsulfenamide with respect to 100 parts by weight of raw material. The composition improves the change of physical property after aging as much as 3-3.5 times and a compression set as much as 36%, reduces a creep amount of engine mount, and ensures a sufficient durability.
    • 用途:提供一种用于发动机悬置的橡胶组合物,其包含相对于100重量份的生橡胶为5-10重量份的1,2-聚丁二烯和1-2重量份的磷酸三(单壬基苯基)酯,由此 通过添加助剂和防老化剂来改善耐热性并使永久变形最小化。 构成:发动机安装用橡胶组合物包含相对于100重量份生橡胶为5-10重量份的1,2-聚丁二烯和1-2重量份的磷酸三(单壬基苯基)酯。 相对于100重量份的原料,橡胶组合物包含1〜1.5重量份的硫,0.5〜1重量份的二硫化四甲基秋兰姆和0.2〜0.5重量份的N-环己基-2-苯并噻唑基亚磺酰胺。 该组合物改善了老化后物理性能的变化多达3-3.5倍,压缩变形高达36%,减少了发动机支架的蠕变量,并确保了足够的耐久性。
