As a new building material,EVG-3D type industrial prefabricated plate has excellent fireproof and heat insulation performance. This paper tests the performance of EVG-3D board. The results showed that:the unexposed surface single point of maximum temperature rise to 162.8 degrees,the average temperature rise to 139.3 degrees,which are consistent with the existing specifications. There is no smoke coming out for the EVG-3D plate specimens,and the specimens are integrated at the end of the experiment. From the experimental data and the experimental phenomenon,the EVG-3D board has good insulation and environmental protection performance,which provides an important basis for the use of EVG-3D board in our building.
