Abstract

The invention provides performance detection equipment and a detection method for an automobile electronic heat insulation material, and relates to the field of material performance detection.The performance detection equipment comprises an adjusting mechanism and a detection mechanism, the heat insulation material is placed in an inner cavity of an assembly ring, and the fit degree of the device to the heat insulation material is increased through shrinkage of the distance of the whole device; air blowing is carried out to an inner cavity of an inner rotating rod, air blows the side end of a heat insulation material, air speed detection mechanisms are installed at the two ends of the inner rotating rod, reverse impact wind power is generated when the air blows to the side end of the heat insulation material when the air blows to the inner end, and the air permeability of the heat insulation material is judged by capturing the air speed of the air. By pressing the side end of the mounting disc, the middle connecting transverse cylinder is pushed towards the side end, the assembling column is matched with the inner connecting disc, the steps are repeated, the first adjusting mechanism generates airflow differential change, and the stability of the heat insulation material under the airflow differential condition is detected.

Description

technical field [0001] The invention relates to the field of material performance detection, in particular to a performance detection device and a detection method for automotive electronic heat insulation materials. Background technique [0002] Heat insulation materials are divided into three categories: porous materials, heat reflective materials and vacuum materials. The former uses the pores contained in the material itself to insulate heat, because the thermal conductivity of air or inert gas in the pores is very low, such as foam materials, fiber materials, etc.; heat reflective materials have a high reflection coefficient and can reflect heat, such as Gold, silver, nickel, aluminum foil or metal-plated polyester, polyimide film, etc. Vacuum insulation materials use the internal vacuum of the material to block convection and insulate heat. The aerospace industry has strict requirements on the weight and volume of the insulation materials used, and often requires the...
