摘要：

选取汽车车身和未涂装底材进行模拟实验，观察其在不同受热时间、受热温度和冷却条件下的受热痕迹特征，通过对比分析，研究汽车车漆对车身受热痕迹的影响。实验表明，车漆对底材具有一定的保护作用，在自然冷却条件下的保护效果好于在水冷条件下的保护效果；自然冷却条件下，车身不会出现锈蚀现象；受热温度对车漆的影响远大于受热时间对车漆的影响。同时，将调查结论紧密结合实际工作，提出车身受热痕迹现场判别方法，对汽车火灾调查具有一定参考价值。

Abstract:

Bodywork of a car and uncoated base material are selected for simulation experiment, and the characteristics of heating trace under different heating time, temperature and cooling conditions are observed. Through comparative analysis, the influence of automobile paint on heating trace of bodywork of a car is studied. Experiments show that car paint has a certain protective effect on the base material, and the protective effect under natural cooling is better than that under water cooling; Under natural cooling conditions, the car body will not rust; The influence of heating temperature on car paint is far greater than that of heating time. At the same time, combining the investigation conclusion closely with practical work, this paper puts forward the on-site discrimination method of heat marks of bodywork of a car, which has certain reference value for automobile fire investigation.
