- the thus prepared superabsorbent resin composition was referred to as Example 3.
- Example 4 2 parts by weight of a particulate antimicrobial agent containing a quaternary ammonium salt of a silane compound having a product name of Biosafe (including the chemical formula 2) and 1 part by weight of sodium salt of EDTA-2Na (EDTA-2Na) were added to 100 parts by weight of the superabsorbent resin, followed by stirring at 500 rpm for 2 minutes using a blender.
- the thus prepared superabsorbent resin composition was referred to as Example 3.
- Example 4 2 parts by weight of
- a superabsorbent resin was prepared in the same manner as in Example 1.
- Example 4 2 parts by weight of a particulate antimicrobial agent containing quaternary ammonium salt of a silane compound having a trade name of Biosafe (including formula (2)) per 100 parts by weight of the superabsorbent resin, 99 parts by weight of a sodium methacrylate salt , And 1 part by weight of a sodium salt of a seedling (EDm-2Na) were added to the mixture, followed by stirring at 500 rpm for 2 minutes using a Plowshare blender.
- the thus prepared superabsorbent resin The composition is referred to as Example 4. Comparative Example 1
- a superabsorbent resin was prepared in the same manner as in Example 1. This superabsorbent resin itself was used as Comparative Example 1. Properties of high water-based resin
- Example or Comparative Example 2 g of the superabsorbent resin composition of Example or Comparative Example was added to 50 ml of artificial urine inoculated with Proteus mirabillis (ATCC 29906) at 390000 CFU / ml and cultured in a 35 ° C oven for 12 hours. After culturing for 12 hours, artificial urine was washed well with MOml brine to measure CFU (Colony Forming Unit). The antimicrobial / deodorizing properties of each Example and Comparative Example were calculated / evaluated.
- the superabsorbent resin composition of the Example exhibited an improvement of at least the same level as the comparative example, despite the addition of the functional additive, Antibacterial / deodorant properties.
