    • Disclosed is an acrylic rubber composition comprising, based on 100 parts by weight of carboxyl group-containing acrylic rubber, 0.05 to 5 parts by weight of a diurethane compound represented by the general formula: R2(SO2)m(CH2)nOCONHR1NHCOO(CH2)n(SO2)mR2 (R1: a divalent organic group; R2: when it is in a carbamate structure form, a group that decomposes by the action of a basic vulcanization accelerator; n: 0, 1, or 2; and m: 0 or 1), 0.3 to 3 parts by weight of a diaminodiphenyl ether-based compound, and 0.08 to 1.2 parts by weight of an N-containing heterocyclic compound; the composition being free from 1,3-o-tolylguanidine. This acrylic rubber composition allows high-speed vulcanization, without using 1,3-di-o-tolylguanidine generating o-toluidine, and has excellent scorch stability. Furthermore, the vulcanization-molded product of the acrylic rubber composition can sufficiently satisfy compression set characteristics required for sealing parts.
    • 公开了一种丙烯酸类橡胶组合物,其包含基于100重量份的含羧基的丙烯酸橡胶,0.05〜5重量份的由通式R2(SO2)m(CH2)nOCONHR1NHCOO(CH2)表示的二氨基甲酸酯化合物, n(SO 2)m R 2(R 1:二价有机基团; R 2:当其为氨基甲酸酯结构形式时,通过碱性硫化促进剂的作用分解的基团; n:0,1或2; m:0 或1),0.3〜3重量份的二氨基二苯醚系化合物和0.08〜1.2重量份的含N杂环化合物; 该组合物不含1,3-邻甲苯胍。 该丙烯酸橡胶组合物不使用产生邻甲苯胺的1,3-二邻甲苯胍,能够进行高速硫化,具有优异的焦烧稳定性。 此外,丙烯酸橡胶组合物的硫化成型品可以充分满足密封部所需的压缩变形特性。
