一种轴封用耐发泡HNBR胶料及其制备方法

本发明属于橡塑密封技术领域，具体涉及一种轴封用耐发泡HNBR胶料及其制备方法。耐发泡HNBR胶料按照质量份数的组成为：氢化丁腈橡胶100份，填料20～100份，活性剂2～10份，硅烷偶联剂0.5～5份，防老剂0.5～6份，硫化助剂2～5份，硫化剂3～6份，所述填料由炭黑、白炭黑和木质纤维素复合而成。本发明制备的氢化丁腈橡胶材料，具有耐-40～175℃以上的高低温，以及耐R1234yf/POE油的特点，产品能够满足空调压缩机轴封苛刻工况条件下的使用。 The invention belongs to the technical field of rubber and plastic sealing, and particularly relates to a foaming-resistant HNBR rubber material for a shaft seal and a preparation method of the foaming-resistant HNBR rubber material. The foaming-resistant HNBR rubber material comprises the following components in parts by mass: 100 parts of hydrogenated butadiene-acrylonitrile rubber, 20-100 parts of filler, 2-10 parts of an active agent, 0.5-5 parts of a silane coupling agent, 0.5-6 parts of an anti-aging agent, 2-5 parts of a vulcanizing aid and 3-6 parts of a vulcanizing agent, wherein the filler is formed by compounding carbon black, white carbon black and lignocellulose. The hydrogenated butadiene-acrylonitrile rubber material prepared by the invention has the characteristics of re
