Abstract

The invention discloses a method for testing harmful volatile matters in a non-metallic material of a passenger vehicle. The method comprises the following steps: putting a non-metal material into a sampling bag; arranging a blank sampling bag with the same specification; separating harmful volatile substances from an adsorption object to be detected through heating; collecting benzene substancesthrough a TENAX sampling tube; extracting benzene substances in the TENAX sampling tube through a thermal desorption system; introducing the benzene substances into a gas chromatography-mass spectrometer; obtaining a quantitative value of each benzene substance through a benzene substance analysis curve; and collecting aldehyde ketone substances through a DNPH sampling tube, eluting the DNPH sampling tube through acetonitrile to prepare an aldehyde ketone substance reagent, guiding the aldehyde ketone substance reagent into a high performance liquid chromatograph-diode array detector, obtaining quantitative values of the aldehyde ketone substances through an aldehyde ketone substance analysis curve, and finally obtaining the concentration of harmful volatile substances through calculation.By detecting the concentration of harmful substances volatilized from various non-metallic materials, the unqualified automotive trim assembly is locked, and targeted improvement is achieved.

Description

technical field [0001] The invention belongs to the technical field of detection of harmful volatiles in the interior environment of automobiles, and in particular relates to a method for testing harmful volatiles of non-metallic materials in passenger cars. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, passenger cars have become an indispensable means of transportation for people to travel. With the continuous popularization of passenger cars, the public has higher and higher requirements for the power performance, fuel economy, braking performance, handling stability and ride comfort of passenger cars. [0003] In recent years, with the continuous improvement of the public's environmental awareness, that is, the awareness of self-protection, the problem of interior space pollution of passenger cars has been exposed to the public more and more. As early as 2013, there have been c...
