Graphene oxide modified diatomite fireproof thermal insulation board
The invention discloses a preparation method comprising the steps: step 1, preparing graphene oxide; step 2, preparing a graphene oxide/diatomite composite material; and step 3, preparing the fireproof thermal insulation board: firstly, taking polystyrene particles, graphene oxide/diatomite, a binder, clay powder, a flame retardant, aluminate cement and water in parts by weight and mixing to obtain a mixture; then adding the mixture into a shaping mold, placing the shaping mold in a press machine, making the mixture be in a compact state through exhausting, pressing and pressure maintaining, and demolding to obtain a blank; and maintaining the obtained blank, and drying until the moisture content of the blank is less than 1% to obtain the fireproof thermal insulation board. The thermal insulation board has the advantages of accessible raw materials and simple preparation technique, and is convenient to operate; by adopting a mode of compounding an organic material and an inorganic material, the preparedthermal insulation board is high in compressive strength and tensile strength, good in thermal insulation performance, low in volume water absorption rate, non-combustible in fireproof grade and suitable for industrial large-scale production.
本发明公开了步骤一，氧化石墨烯的制备；步骤二，氧化石墨烯/硅藻土复合材料的制备；步骤三，防火保温板的制备：首先按以下重量份取聚苯乙烯颗粒、氧化石墨烯/硅藻土、粘结剂、粘土粉、阻燃剂、铝酸盐水泥和水混合，得到混合料；然后将混合料加入定型模具后，将定型模具置于压力机中，经排气、压制、保压使混合料达到密实状态，脱模、得到毛坯；将上述得到的毛坯进行养护，干燥至毛坯水分含量小于1%，即可得到防火保温板。本发明保温板原料易得、制备工艺简单、方便操作；采用有机材料与无机材料相复合的方式，制备的保温板抗压强度和抗拉强度高，兼具良好的保温性能，保温板的体积吸水率低，防火等级为不燃级，适合工业化大规模生产。
