The invention discloses a high temperature resistant single component high iron pantograph conductive adhesive formula, which is composed of four-functional epoxy resin 10_20%, three-functional epoxy resin 10_20%, toughening agent 3_8%, silane coupling agent 0.5_1%, main curing agent 2_4%, accelerator 1_2%, carbonyl nickel powder 40_60%, graphene micro. The invention has the advantages of using a single component heat curing process, improving the working efficiency of the pantograph carbon slide bonding process using a two-component glue and manual stirring copper powder, using nickel powder to fill, avoiding the non-conductive problem caused by oxidation of the copper surface filled with copper powder, and using graphene micro-sheet as the anti-sedimentation. Thixotropic agent and auxiliary conductive agent can prevent the metal particle sedimentation caused by long-term storage, thixotropy can also effectively prevent the glue thinning in the heating process caused by crack filling dissatisfaction; the actual conductivity of one-component glue is far better than that of two-component copper powder, so in actual operation, the copper mesh can be cancelled. The process is reduced and the efficiency is improved.
【技术实现步骤摘要】
一种耐高温单组份高铁受电弓导电胶配方
本专利技术涉及导电胶
,尤其涉及一种耐高温单组份高铁受电弓导电胶配方。
技术介绍
目前,受电弓行业的导电胶水大多是自配,以双组份环氧胶加人工搅拌铜粉再加铜网的方式为主,因此工作效率较低;此外,目前的双组份加铜粉方式,实际大多不含增韧剂,胶水脆性较大,碳-铝剪切拉力大多在8-12兆帕之间;最后,现有的人工搅拌胶水为了方便搅拌,胶水较稀,流动性好,加热固化过程中会导致边缘流胶,需要边缘填缝胶补强,类似植树的边缘培土效果,以防止受电弓随动车高速运动过程中碳滑板沿着缝隙脱胶。
