Abstract Four types of film forming materials were used in graphene fire resistive coatings to investigate the fire protection, smoke suppression, water resistance and physical properties by corresponding tests. Firstly, weather resistance of emulsions was tested and evaluated. Additionally, distribution state of graphene in the emulsion was conducted by precipitation method test, particle size distribution test and contact angle test, respectively. The impact test and adhesion test were carried out to evaluate physical properties of coatings. TGA was used to studied thermal stability of coatings and SEM was carried out to analyze the microstructure of carbon layers. The results demonstrated graphene could well dispersed in vac-veova emulsion and the corresponding graphene fire resistive coating performed best in fire protection, smoke suppression, thermal stability and water resistance. Although silicone acrylic emulsion exhibited poor weather resistance, graphene fire resistive coating contained silicone acrylic emulsion performed better in the adhesion test and impact test due to the silicon element.

成膜材料对石墨烯防火涂料性能的影响

摘要 采用四种成膜材料制备石墨烯防火涂料，通过相应的试验研究其防火、抑烟、防水和物理性能。首先，对乳液的耐候性进行了测试和评价。此外，石墨烯在乳液中的分布状态分别通过沉淀法测试、粒度分布测试和接触角测试进行了测试。进行冲击试验和附着力试验以评价涂层的物理性能。TGA用于研究涂层的热稳定性，并进行SEM分析碳层的微观结构。结果表明，石墨烯可以很好地分散在 vac-veova 乳液中，相应的石墨烯防火涂料在防火、抑烟、热稳定性和防水性。尽管有机硅丙烯酸乳液的耐候性较差，但由于含有硅元素，含有有机硅丙烯酸乳液的石墨烯防火涂料在附着力测试和冲击测试中表现更好。
