摘要: 为满足钢结构防腐防火一体化需求,结合聚苯胺的钝化防腐功能以及玄武岩鳞片的阻隔屏蔽作用,采用原位聚合方法制备了聚苯胺(PANI)改性玄武岩鳞片(BS)复合材料(PANI-BS)。对复合材料的形貌、组成和结构进行分析,并考察了该复合材料在水性环氧体系中的协同防腐蚀以及防火隔热性能。结果表明:通过草酸掺杂和原位聚合成功制备了PANI修饰改性的BS,PANI-BS在纯环氧体系中具有良好的防腐蚀功能,通过搭配三元阻燃膨胀剂制备的环氧防火涂层也展现出良好的防火隔热性能。涂层综合性能与PANI-BS添加量相关,其中,含3%复合材料的涂层具有最佳的防腐防火能力。试验表明,PANI-BS在防腐防火一体化中具有良好的应用潜力。

Abstract: In order to meet the integrated requirements of anti-corrosion and fire prevention for steel structures, by leveraging the passivation anti-corrosion function of polyaniline and the barrier shielding effect of basalt scales, polyaniline (PANI) modified basalt flakes (BS) composite material (PANI-BS) was prepared by in-situ polymerization method. The morphology, composition and structure of the composite material were analyzed, and the synergistic anti-corrosion and fire resistance properties of the composite material in waterborne epoxy system were investigated. Results showed that PANI coated modified BS can be obtained through oxalic acid doping and in-situ polymerization. PANI-BS has good anti-corrosion function in pure epoxy system, and the epoxy fireproof coating prepared by combining with ternary flame retardant expansion agent also exhibits good fire resistance performance. The comprehensive performance of the coating is related to the amount of PANI-BS added, and the coating containing 3% composite material has the best anti-corrosion and fireproof ability. The experiment shows that PANI-BS has good potential for application in the integration of anti-corrosion and fire prevention requirements.
