主要研究了PP/EPDM/黏土(聚丙烯/三元乙丙橡胶/黏土)纳米复合材料的热传导特性。总共设计了六种不同的配方,其中的黏土含量分别为0、2%、4%和6%,采用熔融混合方法制备纳米复合材料的试验样品。为了达到设定的研究目的,在不同温度条件下,通过试验测试了不同配方的纳米复合材料的密度、比热容和热传导率。在研究过程中,开发了一种新型的逆向传热分析方法,用于判定材料的导热性。首先,假设纳米复合材料的导热性具有线性相关性,固体样品的瞬态热传导方程可以通过数
Mainly studied the thermal conductivity of PP / EPDM / clay (polypropylene / EPDM / clay) nanocomposites. A total of six different formulations were designed with clay contents of 0, 2%, 4% and 6%, respectively, and the melt-mixed method was used to prepare the test samples of the nanocomposites. In order to achieve the set research purpose, the density, specific heat capacity and thermal conductivity of different formulations of nanocomposites were tested under different temperature conditions. In the course of the study, a new method of inverse heat transfer analysis was developed to determine the thermal conductivity of the material. First, assuming that the thermal conductivity of nanocomposites has a linear dependence, the transient heat conduction equation for solid samples can be obtained by
