中文摘要:
      以腰果酚改性酚醛胺固化剂,将石墨烯掺杂到环氧树脂(EP)中制备了防腐涂料,并将其涂覆在预处理的基材马口铁上。对复合涂层的表面形貌、固化时间、光泽度、附着力、抗冲击性能、硬度,柔韧性和防腐性能进行了测试。结果表明,腰果酚改性酚醛胺固化剂制备的涂层具有优良的力学性能和防腐性能,且随着石墨烯含量的增加,涂层防腐性能提高。当腰果酚改性酚醛胺含量为25%,石墨烯的含量为6%(以EP质量为基准),涂层的平均厚度为(120±10) μm,硬度可达到2H,附着力达到1级,自腐蚀电流密度为8.482×10-6 A/cm,腐蚀速率为6.593×10-2 mm/y,具优良力学性能与防腐性能。
英文摘要:
      Epoxy resin (EP) was compounded with cardanol modified phenalkamine curing agent and graphene was doped into epoxy resin to prepare anticorrosive coating. The prepared anticorrosive coating was coated on the substrate tinplate to obtain a coating possessing both excellent mechanical properties and corrosion resistance. The surface morphology, curing time, gloss, adhesion, impact resistance, hardness, flexibility and corrosion resistance of the coating were tested. The results showed that the cardanol modified phenalkamine can achieve the excellent mechanical properties and corrosion resistance of the traditional low-grade fatty amine curing agent, and with the increase of graphene content, the coating anticorrosion performance was improved accordingly. The prepared coating containing 25% cardanol modified phenalkamine and 6% graphene paste exhibited the best performance, the average thickness of the coating is 120±10μm, the hardness is 2H, the adhesion is 1 level, the corrosion current density is 8.482×10-6 A/cm2 and the corrosion rate is 6.593×10-2 mm/year.
