Definitions

  • the present invention relates to a fiber mat including SBS and a method of manufacturing the same, and more particularly, to a SBS fiber mat having improved water absorption compared to a fiber mat manufactured by SBS alone.
  • SBS generally refers to a block copolymer containing styrene-butadiene-styrene triple block. SBS has various uses, and is widely used for heat modifiers, asphalt modifiers, plastic modifiers, and compounding compounds. It is used.
  • Polystyrene chains in SBS are strong and hard plastics, which enhance the durability of SBS, and polybutadiene is a rubbery material, which acts to make SBS behave like rubber.
  • SBS exhibits the properties of rubber at room temperature and can be melted and molded like plastic when heat is applied.

  • Electrospinning is the only way to produce continuous, high-volume nanofibers from a variety of polymers and has several advantages: That is, it is possible to produce fibers having various diameters ranging from several nm to several hundred nm, and the equipment is simpler than the conventional nonwoven fabric matrix manufacturing method, and can be applied to a wide range of polymer materials. Electrospinning is the process of producing a non-woven matrix of nanofibers by releasing a millimeter diameter liquid jet through a thin glass tube or nozzle. One side of the electrode is in the polymer solution, and the other is located between the two electrodes with opposite polarities, located in the collector. The polymer solution is radiated once through a thin outlet and the solution evaporates and the fibers are collected in the collector.
  • the potential difference applied depends on the properties of the spinning solution, the molecular weight of the polymer, the viscosity, and the like. If the distance between the outlet and the collector is short, the evaporation of the solvent is not sufficient, so the fibers are entangled with each other as well as with the collector.
  • the principle that nanofibers are made is that as the electric field increases, the liquid at the end of the capillary changes from a hemispherical to a conical form known as the Taylor cone. As the electric field increases further, the repulsive force becomes greater than the surface tension, and the electrostatic liquid is radiated in the form of thin fibers in the Taylor cone at the capillary end.
  • the determinants of the properties of the nanofibers are mainly determined by the properties of the polymer solution and the properties of the electrospinner.

Abstract

La présente invention résout le problème selon lequel il manque aux tapis de fibres fabriqués en SBS la possibilité de les utiliser pour absorber l'eau, du fait de la faible capacité d'absorption de l'eau de ces tapis. Cependant, la présente invention est caractérisée en ce qu'un tapis est fabriqué par filage après l'ajout de poly(éthylène glycol)-b-poly (propylène glycol)-b-poly (éthylène glycol) au SBS, ce qui conduit à une meilleure absorption de l'eau.
