Abstract: The present invention relates to a method of preparing a water-based surface treatment agent and a water-based surface treatment agent prepared using the same. More particularly, the present invention relates to a water-based surface treatment agent used to form a surface treatment layer included in artificial leather for automobile seat covers and a method of preparing the water-based surface treatment agent. According to the present invention, when the water-based surface treatment agent is used to manufacture artificial leather, occurrence of whitening of the surface of the artificial leather may be prevented.

Abstract: Provided are a seat cover for an automobile and a manufacturing method therefor, the seat cover comprising a surface-treated layer, a cover layer, a soft foam layer, and a rear layer and comprising an embossing pattern formed on the top surface, wherein the soft foam layer comprises 15 to 20 foam cells per unit area of 1 mm2 of the surface thereof.

Abstract: The present invention relates to artificial leather, and more particularly, to artificial leather for automobile seat covers having excellent surface appearance and a method of manufacturing the artificial leather. When the artificial leather of the present invention is manufactured, surface treatment is performed before embossing molding that imparts a texture and cushioning similar to natural leather to artificial leather. Accordingly, the artificial leather of the present invention may be provided with a surface treatment layer having a uniform thickness, thereby exhibiting excellent surface appearance.

Abstract: The present invention relates to artificial leather and a method of manufacturing the same. More particularly, the present invention relates to artificial leather for automobile seat covers, the artificial leather having a texture similar to that of natural leather, having a soft feel like natural leather, and having excellent peel strength and a method of manufacturing the artificial leather.

Abstract: Disclosed are an artificial leather used as an interior material for automobiles and a method for manufacturing the same, in one aspect a polymer plasticizer, a PVC resin and a foaming agent. The soft artificial leather for interior materials of automobiles includes a skin layer including a PVC resin and a primary plasticizer, wherein the skin layer further includes higher than 0 and not higher than 15 phr of a polymer plasticizer. As a result, there are effects of reducing heating loss and suppressing migration of the plasticizer.

Abstract: Disclosed is an aqueous composition for surface coating, including: a main ingredient comprising a first compound having at least two functional groups selected from the group consisting of a carboxyl group, a hydroxyl group, an amino group and combinations thereof, per molecule; a curing agent comprising a second compound having at least two functional groups selected from the group consisting of an aziridine group, an isocyanate group, a carbodiimide group and combinations thereof, per molecule; and an aqueous solvent. Further, an automotive sheet using the aqueous composition for surface coating is disclosed.

Abstract: A method and an apparatus for distinguishing radionuclides are disclosed. The method comprises the steps of: receiving energy generated in one or more radioactive elements; applying energy as a weight for each channel to spectrum of the received energy; and distinguishing the one or more radioactive elements on the basis of the spectrum of the spectrum to which the weight is applied. A radioactive element having an energy value corresponding to a peak value of the spectrum of the energy to which the weight is applied, as an energy value of a Compton edge, is distinguished as the one or more radioactive elements. According to the present invention, it is possible to more accurately monitor radiation even while using a plastic scintillator, and further to improve energy resolution of a plastic scintillator.
