The invention relates to a measurement method for migration quantity of diisopropylnaphthalene in silicone oil paper. The measurement method comprises the following steps of preparing a diisopropylnaphthalene standard storage liquid, a diethyl naphthalene internal standard storage liquid, an alcohol standard working solution and an oil-based standard working solution; allowing a silicone oil papersample with area being 6dm<2> to contact with 1-kilogram food simulation substance for migration experiment on, fetching the migrated simulation liquid in a centrifugal tube with a plug, adding sodium chloride, ethyl acetate and the internal standard storage liquid, performing ultrasonic extraction, and taking a liquid supernatant for GC-MS analysis; and selecting ion detection, and quantifying by an internal standard method to obtain the migration quantity of the diisopropylnaphthalene. By optimizing pre-processing flow before detection, computer programming, selection of a GC-MS chromatographic column and temperature rising program, the migration quantity detection time of the diisopropylnaphthalene is greatly reduced, the working efficiency is improved, and meanwhile, the detection limit is reduced. The method is simple and rapid and has excellent sensitivity and stability, and analysis detection and accurate quantification of the migration quantity of diisopropylnaphthalene in thesilicone oil paper are met.
