Graphene modified siliceous rock insulation board and manufacturing method thereof
The invention discloses a graphene modified siliceous rock insulation board. The graphene modified siliceous rock insulation board is prepared from the following components in percentage by weight: 60percent of inorganic adhesive mortar and 40 percent of solid filler, wherein the solid filler is prepared from the following components in percentage by weight: 25 to 35 percent of ground calcium carbonate, 15 to 25 percent of fly ash, 15 to 25 percent of silica fume and 20 to 30 percent of GM-EPS particles. According to the graphene modified siliceous rock insulation board and the manufacturingmethod thereof, the fireproof performance of the prepared siliceous rock insulation board reaches grade A after being modified by graphene; when the volume density is 140-160kg/m<3>, the heat conductivity coefficient can reach 0.044 and is reduced by more than 15% compared with that of the siliceous rock insulation board prepared from common EPS; the inorganic adhesive material and the GM-EPS particles are adopted, so that compared with a siliceous rock insulation board prepared from common EPS particles, the tensile strength of the graphene modified siliceous rock insulation board is improvedby 20%, and the compressive strength of the graphene modified siliceous rock insulation board is improved by 10%.
本发明公开了石墨烯改性硅岩保温板，由重量百分比为60％的无机胶粘浆料和40％的固体填充料组成，固体填充料包括重量百分比为25‑35％的重质碳酸钙、15‑25％的粉煤灰、15‑25％的微硅粉以及20‑30％的GM‑EPS颗粒。该石墨烯改性硅岩保温板及其制造方法制得的硅岩保温板经石墨烯改性后的防火性能达到A级，体积密度在140～160kg/m3时的导热系数可达到0.044较之普通EPS制备的硅岩保温板下降15％以上，采用无机胶粘材料及GM‑EPS颗粒，使得石墨烯改性硅岩保温板，较之普通EPS颗粒制备的硅岩保温板，其抗拉强度提高20％，抗压强度提高10％。
