The invention belongs to the field of rubber composite materials, and particularly relates to a new energy vehicle and a high-temperature-resistant material. The new energy vehicle comprises a battery compartment and a passenger compartment, the passenger compartment comprises a passenger compartment floor, a high-temperature-resistant heat insulation layer is arranged on the side, facing the battery compartment, of the passenger compartment floor, the high-temperature-resistant heat insulation layer comprises an ablation-resistant layer and a heat insulation layer, one side of the ablation-resistant layer faces the battery compartment, the other side of the ablation-resistant layer faces the passenger compartment floor, and the heat insulation layer is arranged on the ablation-resistant layer. The ablation-resistant layer is prepared from the following raw materials in parts by weight: 100 parts of silicone rubber, 100-200 parts of reinforced fibers, 20-25 parts of a reinforcing agent, 0.5-1.5 parts of a vulcanizing agent and 3-10 parts of a flame retardant. According to the new energy vehicle, when the battery is on fire due to thermal runaway, the ablation-resistant layer is subjected to thermal oxidation decomposition to form a compact carbonization layer to block flame diffusion, and the thermal insulation layer plays a role in delaying temperature rise of the passenger compartment, so that time is won for passengers to escape, and casualties in accidents are reduced.
本发明属于橡胶复合材料领域,具体涉及一种新能源车辆及耐高温材料。该新能源车辆包括电池舱和乘员舱,乘员舱包括乘员舱地板,乘员舱地板朝向电池舱一侧设置有耐高温隔热层,所述耐高温隔热层包括耐烧蚀层和隔热层,所述耐烧蚀层的一侧朝向电池舱,另一侧朝向乘员舱地板并设置所述隔热层,所述耐烧蚀层由以下重量份的原料制成:硅橡胶100份,增强纤维100~200份,补强剂20~25份,硫化剂0.5~1.5份,阻燃剂3~10份。本发明的新能源车辆,当电池出现热失控着火时,耐烧蚀层热氧化分解,形成致密的炭化层,阻断火焰扩散,隔热层起到延缓乘员舱温度升高的作用,为乘员逃生赢得时间,减少事故人员伤亡。
