摘　　要：为验证纳米陶瓷微珠保温隔热材料的热工性能,可采用实验室导热系数法、防护热箱法和模拟房对比法三种方法对比测试材料热阻。结合测试数据分析,发现采用传统的实验室导热系数法对具有辐射热效应的纳米陶瓷微珠节能材料进行测试得出的导热系数不能体现其优异的热阻性能;而对采用实验室防护热箱法与模拟房对比法测试数据进行对比研究,发现在不同的温差环境下测试结果有很大区别。本文以纳米陶瓷微珠保温隔热材料为例,详述材料热工性能的检测与分析,为行业提供参考。In order to verify the thermal performance of the thermal insulation material of nano-ceramic microsphere,the thermal resistance of the material was measured by three methods,namely the laboratory thermal conductivity method,the protective hot box method and the simulation room comparison method.Combined with test data analysis,it is found that the thermal conductivity of the energy-saving nano-ceramic beads with radiant thermal effect can not reflect its excellent thermal resistance by using the traditional“laboratory thermal conductivity method”.By comparing the test data of“laboratory protective hot box method”and“simulation room comparison method”,it is found that the test results are quite differentiated under different temperature difference environments.Taking nano ceramic bead thermal insulation materials as an example,this paper describes the detection and analysis of thermal performance of materials in detail so as to provide reference for the industry.
