转向减震器柔性储油囊的研制

Preparation of Rubber Tube Used in Steering Bumper

本文对转向减震器柔性储油囊进行研制,确定了下列的配方,丁腈橡胶100,硫化剂4.5,防老化剂2,氧化锌5,硬脂酸0.5,增塑剂10,高耐磨炭黑35,对该种材料进行了材质试验:抗拉强度14.2N/mm^2,断裂伸长率290%,肖氏A硬度62,50%定伸应力1,46N/mm^2,由该材料制成的零件进行6万km的道路试验,性能优良,通过与CKD 零件的对比试验表明,该材料优于CKD 材料。

The new formulation of rubber tube used in steering bumper has beenprepared,The formulation(phr) is as follow:nitrile rubber 100,curing agent4.5,antioxidant RD and MB2,zinc white 5,stearic acid 0.5,plasticizer 10 andsemireinforcing carbon black 35,The properties of the production by this formulation is as follow:tensile strength 14.2N/mm^2,elongation at break 290%,shore-A-hardness 62,50% tensile strength 1.46N/mm^2,The parts made by this formulationare tested through 60000 kilometers road-test and express good properties,The partsare better than CKD-parts through comparing-test,
