Abstract

The invention belongs to the technical field of electronics and in particular relates to a detection method of three types of phosphorus based flame retardant in a polyurethane foam product. Detection targets are phosphorus based flame retardants, namely tris(1-chloro-2-propyl) phosphate (TCPP), tris(2-chloroethyl) phosphate (TCEP) and tris(2,3-dichloropropyl) phosphate (TDCPP); under certain temperature and time, an organic solvent is used for carrying out ultrasonic extraction, and a gas chromatograph mass spectrometer is used for determining. The method provided by the invention has high sensitivity, high recovery rate and goo precision of a determined result.

Description

[0001] 1. Technical field [0002] The invention belongs to the technical field of electronic detection, and in particular relates to a detection method for three prohibited phosphorus-based flame retardants in polyurethane foam products. [0003] 2. Technical background [0004] In recent years, the demand for flame retardants has been increasing. Phosphorus-based flame retardants are widely used and have high efficiency, but they are bioaccumulative. Long-term contact with phosphorus-containing flame retardants will have adverse effects on the human body, such as Deterioration of immune system function, reproductive system disorders, memory loss, and even cancer. [0005] At present, many countries have their own flame retardant regulations or standards, such as UL standard (American Insurance Institute standard), ASTM standard (American Society for Testing Materials standard), CSA standard (Canadian Industrial Standards Association standard), JIS standard (Japanese standard)...
