Abstract

Nowadays, intumescent paint is one of the most popular fireproof paint products and is widely used in buildings. They can be applied to steel, wood, concrete, etc. This study aimed to enhance the properties of intumescent coating by graphene addition. The effect of graphene (GR) content on fire resistance, thermal and mechanical properties of water-based intumescent coatings were studied. Intumescent coating formulations include acrylic emulsion binder (R4152), flame retardant additives (Ammonium polyphosphate (APP) - acid source, pentaerythritol (PER) - carbon source, melamine (MEL) - foaming source), fire retardant fillers (TiO2, Al(OH)3) were prepared by mixing different graphene content (0.5, 1, 1.5 and 2 wt.% GR). The investigated coating properties were examined by fire protection test, furnace test, static water immersion test, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and mechanical properties (adhesion, pendulum hardness). The results showed that the GR could effectively enhance the fire resistance performance (from 13.6 % to 23.4 %), thermal stability (from 2.9 % to 5.2 %), water resistance (from 5.0 % to 11.9 %), and mechanical properties (from 5 % to 12 %) of the coating.

石墨烯对丙烯酸乳液膨胀型防火涂料性能的影响

膨胀涂料是当今最流行的防火涂料产品之一，在建筑中得到了广泛的应用。适用于钢材、木材、混凝土等。本研究旨在通过添加石墨烯来提高膨胀涂层的性能。研究了石墨烯（GR）含量对水基膨胀涂料的耐火性能、热性能和力学性能的影响。通过混合不同石墨烯含量（0.5、1、1.5和2 wt.% GR），制备了丙烯酸乳液粘结剂（R4152）、阻燃助剂(聚磷酸铵(APP) -酸源、季戊四醇（PER) -碳源、三聚氰胺(MEL) -发泡源）、阻燃填料（TiO2、Al(OH)3）等膨胀涂料配方。采用防火试验、炉窑试验、静水浸泡试验、扫描电镜（SEM）、热重分析（TGA）、差示扫描量热法（DSC）和力学性能（附着力、摆硬度）对涂层进行了表征。结果表明，GR能有效提高涂层的防火性能（由13.6%提高到23.4%）、热稳定性（由2.9%提高到5.2%）、耐水性（由5.0%提高到11.9%）和力学性能（由5%提高到12%）。
