| 石墨聚苯乙烯是在聚苯乙烯高分子聚合物中导入近纳米级天然鳞片石墨、抗氧化剂、抗老化剂等功能材料，改性合成的石墨聚苯乙烯新型功能材料。由于石墨的特殊层状结构，使其能够均匀分布在GEPS颗粒内部，形成镜面反射热辐射，能够大幅度提高材料的绝热效果。除了具备普通EPS板的所有性能外，还具有以下特点：防火性能达到难燃B1级、绝热能力更强、导热系数≤0.032W/(m·K)。它含有近纳米级的天然鳞片石墨，可以像镜子一般反射热辐射,它的绝热能力比普通的EPS高出30%，有助于提高能效。石墨聚苯乙烯特点：良好的防火性能、导热系数低、尺寸稳定性强、耐候性好、具有良好的耐久性和透汽性。 Graphite polystyrene is a new functional material of graphite polystyrene modified by imported nano scale natural graphite, antioxidant, anti-aging agent and other functional materials in polystyrene polymer. Due to the special layered structure of graphite, it can be evenly distributed in the GEPs particles to form specular reflection heat radiation, which can greatly improve the thermal insulation effect of the material. In addition to all the properties of ordinary EPS board, it also has the following characteristics: fire resistance reaches B1 level, thermal conductivity ≤ 0.032w / (m · K). It contains nearly nano scale natural flake graphite, which can reflect thermal radiation like a mirror. Its thermal insulation capacity is 30% higher than ordinary EPS, which helps to improve energy efficiency. Graphite polystyrene features: good fire resistance, low thermal conductivity, strong dimensional stability, good weather resistance, good durability and vapor permeability. |
