Embodiment 1

[0024] A preparation method of polystyrene composite material for packaging board, comprising the following steps:

[0025] (1) After the polycrystalline iron fiber is soaked in water, the speed is 800 rpm and stirred and dispersed for 40 minutes. After sieving, the sieve is extracted with acetone for 24 hours to remove surface impurities, washed with deionized water and placed at a temperature of Dry in an oven at 70°C for 4 hours to obtain purified polycrystalline iron fibers;

[0026] (2) After acrylic acid and AIBN are mixed uniformly, the grafting solution is prepared, and the purified polycrystalline iron fiber obtained in step (1) is cut into a length of 10mm and dissolved in thionyl chloride, and the suspension is obtained after stirring. Put the suspension in an ultrasonic cleaner after adding the grafting liquid, the weight ratio of acrylic acid, AIBN, and purified polycrystalline iron fiber is 1:9:24, ultrasonically vibrate for 40 minutes, distill the material under...

Abstract

The invention provides a preparation method of a polystyrene composite material for wrapping plates, which comprises the following steps: (1) immersing polycrystalline iron fibers in water, dispersing by stirring, screening, extracting the oversize to remove surface impurities, washing, and drying to obtain purified polycrystalline iron fibers; (2) uniformly mixing acrylic acid and AIBN (2,2'-azobisisobutyronitrile) to obtain a grafting solution, shearing the purified polycrystalline iron fibers, dissolving in thionyl chloride, stirring to obtain a suspension, adding the suspension into the grafting solution, putting in an ultrasonic cleaner, carrying out ultrasonic vibration, carrying out vacuum distillation on the material, filtering, washing, and drying to obtain modified polycrystalline iron fibers; and (3) mixing a polystyrene resin, an antioxidant and polythiophene in toluene to obtain a mixed solution, impregnating the modified polycrystalline iron fibers in the mixed solution until all the toluene is volatilized, spreading in a mold, heating and carrying out compression molding to obtain the polystyrene composite material for wrapping plates. The composite material has favorable wave-absorbing capacity, and can effectively resist electromagnetic wave radiation.

Description

Technical field: [0001] The invention relates to a packaging material, in particular to a preparation method of a polystyrene composite material for a packaging board. Background technique: [0002] Packaging board is the board used for packaging products, including the following functions: 1.
