Abstract

The invention discloses a method for measuring the volatilization amount of acrylonitrile monomer in automobile ABS interior trim parts, and the method comprises the following steps: aging the interior trim parts containing ABS components in an ultraviolet aging test box to obtain a sample to be measured, disassembling the sample to be measured, and putting the disassembled sample into a headspacebottle; putting the headspace bottle filled with the to-be-detected sample into a gas chromatograph-mass spectrometer, and setting control conditions of the gas chromatograph-mass spectrometer to volatilize acrylonitrile in the to-be-detected sample so as to obtain acrylonitrile particle strength corresponding to the to-be-detected sample; and obtaining the acrylonitrile volatilization amount inthe to-be-detected sample according to the predicted function relationship between the acrylonitrile particle strength and the acrylonitrile volatilization amount. According to the method for measuring the volatilization amount of the acrylonitrile monomer in the automobile ABS interior trim part, the volatilization amount of the acrylonitrile monomer in the automobile ABS interior trim part can be effectively and rapidly measured, the steps of the measuring method are simple and convenient, and the error range is small.

Description

technical field [0001] The invention relates to the field of auto inspection, in particular to a method for measuring the volatilization amount of acrylonitrile monomers in automotive ABS interior parts. Background technique [0002] In recent years, with the rapid development of the domestic automobile industry and the automobile industry, more and more materials are used in the interior parts of automobiles, and the air quality in the car has gradually attracted people's attention. In-vehicle air pollution sources mainly include automotive interior materials, such as artificial leather, textiles, plastics and a series of pollution sources. Formaldehyde, acetaldehyde, acrolein, and other volatile organic compounds (VOC) released by these pollution sources, as well as amines and nicotine produced by the operation of automobile air conditioners. Among them, the volatile organic compounds (VOC) in the car interior are the main cause of affecting the quality of the air in the ...
