Abstract

The invention discloses a method for measuring the release amount of a vinyl chloride monomer of an automobile PVC (Polyvinyl Chloride) wire ring foot pad. The method comprises the following steps: diluting a vinyl chloride standard substance into standard solutions with different concentrations; respectively putting the standard solutions with different concentrations into the same headspace bottles; respectively putting headspace bottles containing standard solutions with different concentrations into a gas chromatograph-mass spectrometer to obtain particle intensities corresponding to the standard solutions with different concentrations; obtaining a function relationship between the vinyl chloride particle strength and the release amount thereof according to the measured particle strength; disassembling a to-be-detected sample, and putting the disassembled to-be-detected sample into the same headspace bottle; putting the headspace bottle filled with the to-be-detected sample into agas chromatograph-mass spectrometer to obtain the vinyl chloride particle strength corresponding to the to-be-detected sample; and obtaining the vinyl chloride release amount in the to-be-detected sample according to the function relationship of the vinyl chloride release amount. According to the method for measuring the release amount of the vinyl chloride monomer of the automobile PVC wire ringfoot pad, the release amount of the vinyl chloride monomer can be effectively and rapidly measured, and the steps of the measuring method are simple and convenient.

Description

technical field [0001] The invention relates to the field of auto inspection, in particular to a method for measuring the release amount of vinyl chloride monomer from automobile PVC wire ring foot pads. 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 ...
