摘要

为解决传统环氧富锌涂料锌粉含量过高导致的涂层起泡、缩孔、机械性能差等问题,对涂料配方进行优化筛选,并添加超高导电性的石墨烯粉体,制备了一种高性能低锌粉含量环氧防腐涂料。并对涂层的附着力、耐冲击性、耐水性、耐中性盐雾性及耐湿热性等性能进行测试。结果表明:用 19. 35%环氧树脂 E-20、2. 15%聚酰胺加成物固化剂、 45%锌粉、 10%滑石粉、 2%触变剂 881B、1%流平剂 AFCONA-3777、0. 5%石墨烯、 20%稀释剂 2033,制备的环氧石墨烯低锌防腐涂料,涂层具有较高的耐冲击性( 50cm)、附着力( 16 MPa)和优异的耐盐雾性( 2 000 h)、耐水性( 2 000 h)和耐湿热性(2 000 h),可应用于苛刻腐蚀环境。

Abstract

In order to solve the problems such as blistering,shrinkage and poormechanical performance caused by high content of zinc powder in traditional epoxy zinc-richcoatings,the coating formula was optimized and screened. And adding ultra-high conductivitygraphene powder to develop a high-performance graphenel/epoxy coatings with low content ofzinc. The adhesion,impact resistance,water resistance,neutral salt spray resistance and moisture and heat resistance of the coating were tested. The results showed that the graphene/epoxy anticorrosion coatings with low content of zinc prepared by using 19. 35%E-20 epoxy resin,2. 15% polyamide additive curing agent,45% zinc powder,10% talcum powder,2% thixotropic agent 881B,1% leveling agent AFCONA-3777,0. 5% graphene and 20% diluent 2033,the coatings had excellent impact resistance(50 cm),adhesion(16 MPa), 
excellent salt spray resistance(2 000 h),water resistance(2 000 h)and damp heat resistance(2 000 h),which could be used in harsh corrosive environment.
