The invention discloses an automobile ceiling flame-retardant heat-insulating layer material and a preparation method and application thereof, and belongs to the field of automobile materials.The preparation method comprises the following steps that wood flour is soaked in a solvent and fully mixed, and a wood flour solution is obtained; montmorillonite is added into the wood powder solution to be fully mixed, and a mixed solution is obtained; pouring the mixed solution into a mold for low-temperature freezing treatment to obtain a semi-finished product; and freeze-drying the semi-finished product to obtain the flame-retardant heat-insulating layer material for the automobile ceiling. According to the preparation method, the sol-gel process of the wood powder solution is accelerated by adding the montmorillonite, and in the process, the montmorillonite is adhered to the surface of the wood powder through hydrogen bonding and then embedded into the pore structure of the wood powder, so that the pore diameter of the wood powder is reduced, and the specific surface area of pores is increased. The mechanical property of the flame-retardant heat-insulating layer material for the automobile ceiling prepared by the method is remarkably improved, and the flame-retardant heat-insulating layer material has excellent flame-retardant and heat-insulating properties.
本发明公开了一种汽车顶棚阻燃隔热层材料及其制备方法和应用,其属于汽车材料领域,其中,该制备方法包括以下步骤:将木粉浸泡在溶剂中,并进行充分混合,得到木粉溶液;往木粉溶液中加入蒙脱土进行充分混合,得到混合溶液;将混合溶液倒入模具中进行低温冷冻处理,得到半成品;将半成品进行冷冻干燥处理,得到汽车顶棚阻燃隔热层材料。本发明通过蒙脱土的加入加速了木粉溶液的溶胶‑凝胶过程,在此过程中,蒙脱土通过氢键结合粘附到木粉表面,然后嵌入木粉的孔结构中,这使得木粉的孔径减小并且多孔的比表面积增加。通过以上方法制得的汽车顶棚阻燃隔热层材料的力学性能得到显著提高,且具有出色的阻燃、隔热性能。
