摘要
研究了一种可瓷化的柔性隔热板,其特点是常温下为橡胶形态,非气孔性隔热材料,不影响被保护物质的运行导热功能,兼具柔韧性和抗压变性能;高温状态下陶瓷化并形成均匀的层状气孔,迅速起到隔热隔火作用;加工性能优异,适用于挤出、模压等工艺。研究了白炭黑用量及自制隔热粉对隔热板的力学性能及隔热性能的影响,并对其配方进行优化。通过热重分析及多路温度分析仪发现,加入自制隔热粉后,试样烧蚀残留率为77.9%,烧蚀残留率明显提高,同时隔热板上下表面温差可达130℃,可满足新能源电池在高、低温环境下热传导的要求。
This research is to explore a vitrified flexible thermal baffle,which demonstrates rubber properties under room temperature.Non-porosity thermal baffle exert no impact on heat conduciveness for protected material,possessing flexible and pressure-resistant properties.Whereas the thermal baffle forms even layered porosity under high temperature,which immediately insulates heat and fire.The excellent properties make it possible to be processed by extrusion and casting.This article is to optimize its formula by exploring white carbon black dosage and self-made thermal insulation powder’s effect on thermal baffle’s mechanical and thermal insulation properties.The erosion residual rate of the specimen is 77.9%after it is mixed with self-made thermal insulation powder by thermogravimetric analysis and multichannel analysis meter.The erosion rate has witness a significant increase,meanwhile the temperature difference between 2 sides of the thermal baffle reached 130℃,which satisfied heat conduction requirement of new energy battery under high and low temperature conditions.
