description The present invention relates to a powder type vacuum insulator and a method for preparing same. The method is characterized by comprising the steps of: (1) forming an outer skin by welding a barrier thin film on each of a surface and a rear surface of an air permeable envelope having three sealed surfaces and an opening, wherein the outer skin is positioned so that the opening of the air permeable envelope appears outside of an upper end of the barrier thin film, and the side opposite the opening is positioned so as to be hidden inside the barrier thin film, and the left and right ends of the barrier thin film overlap on top of parallel left and right first sealing parts adjacent to the opening of the air permeable envelope, thereby forming a second sealing part; (2) inserting powder into the air permeable envelope of the outer skin through the opening; (3) simultaneously sealing the air permeable envelope and the upper end of the barrier thin film adjacent to the opening; (4) evacuating the inner space of the outer skin; and (5) sealing only a lower end of the barrier thin film which is opposite to the opening. La présente invention concerne un isolateur sous vide de type poudre et son procédé de préparation. Le procédé est caractérisé en ce qu'il comprend les étapes de : (1) formation d'une peau externe par soudage d'un film mince de barrière sur chacune d'une surface et d'une surface arrière d'une enveloppe perméable à l'air comportant trois surfaces scellées et une ouverture, la peau externe étant positionnée de sorte que l'ouverture de l'enveloppe perméable à l'air apparaisse à l'extérieur d'une extrémité supérieure du film mince de barrière, et le côté opposé à l'ouverture est positionné de façon à être masqué à l'intérieur du film mince de barrière, et les extrémités gauche et droite du film mince de barrière se chevauchent au-dessus de premières parties d'étanchéité gauche et droite parallèles, adjacentes à l'ouverture de l'enveloppe perméable à l'air, de façon à former une deuxième partie d'étanchéité ; (2) insertion de poudre dans l'enveloppe perméable à l'air de la peau externe à travers l'ouverture ; (3) simultanément, scellement de l'enveloppe perméable à l'air et de l'extrémité supérieure du film mince barrière adjacente à l'ouverture ; (4) évacuation de l'espace interne de la peau externe ; et (5) scellement d'uniquement une extrémité inférieure du film mince de barrière qui est opposée à l'ouverture. 본 발명은 (1) 3면이 밀봉되고 개구부가 형성된 통기성 봉투의 표면과
