| 摘要: |
| 研究了海泡石为填料时对水性钢结构防火涂料性能的影响,结果表明,通过添加适量的海泡石,水性钢结构防火涂料涂层膨胀状况、防火性能和耐水性能都有很大的改善.此外,随着海泡石用量的增加,水性钢结构防火涂料的粘度增大,耐水性和发泡层硬度显著增强,但涂层膨胀度有所降低.当海泡石用量为2.88%(质量分数)时,水性钢结构防火涂料的综合性能较好. |

| Abstract: |
| The influence of sepiolite on the properties of water-based steel structure fire retardant coating was studied.The experimental results show that the intumescent state,fire retardant property and water resistance of the coating are improved by the addition of proper content of sepiolite.Furthermore,viscosity and water resistance of the coating and hardness of the char layers increase with the increase of content of sepiolite,but intumescent ability is reduced.The optimum content of sepiolite in the coating is 2.88%(mass fraction) by colligating various factors. |
