Title (EN) GASKET AND METHOD FOR MANUFACTURING GASKET
(FR) JOINT D'ÉTANCHÉITÉ ET PROCÉDÉ PERMETTANT LA FABRICATION D'UN JOINT D'ÉTANCHÉITÉ
(KO) 가스켓 및 가스켓 제조방법
Abstract:
(EN) Disclosed are: a gasket, of which a surface state with maximized and homogenized airtight performance can be obtained by using only thermally exfoliated vermiculite (TEV) alone without using chemically exfoliated vermiculite (CEV) while the vermiculite is prepared and used by a superficial layer separation method and thus particles are separated layer-by-layer; and a method for manufacturing the gasket. In order to accomplish the above purpose, according to a preferred embodiment of the present invention, the gasket of the present invention comprises: a first composition obtained by separating TEV mixed with water into 10-2000 micrometers by a superficial layer separation method; a second composition, which is any one selected from sodium carboxymethyl cellulose, methyl cellulose (MC), hydroxypropylmethyl cellulose (HPMC), hydroxyethylmethyl cellulose (HEMC), and hydroxyethyl cellulose (HEC); a third composition, which is any one selected from natural rubber latex, styrene butadiene latex, and nitrile butadiene rubber latex and is fed in a content of 5-15 wt% on the basis of TEV; a fourth composition, which is any one selected from epoxy-based, vinyl-based, amino-based, methacryloxy-based, and styryl-based materials and is fed in a content of 1-3 wt% on the basis of TEV; and a fifth composition, which is any one selected from inorganic binders of modified silicates obtained by modifying colloidal silica, silica sol, or silicate and is fed in a content of 0.1-5 wt% on the basis of TEV.
(FR) L'invention concerne : un joint d'étanchéité, dont un état de surface avec des performances d'étanchéité vis-à-vis de l'air maximisées et homogénéisées peut être obtenu par la seule utilisation de vermiculite exfoliée thermiquement (TEV) seule sans utilisation de vermiculite exfoliée chimiquement (CEV) tandis que la vermiculite est préparée et utilisée par un procédé de séparation de couche superficielle, ce par quoi des particules sont séparées couche par couche ; et un procédé pour fabriquer le joint d'étanchéité. A cet effet, un mode de réalisation préféré de la présente invention porte sur un joint d'étanchéité, lequel joint selon la présente invention comprend : une première composition obtenue par séparation de TEV mélangé à de l'eau sous 10 à 2000 micromètres par un procédé de séparation de couche superficielle ; une deuxième composition qui est l'une quelconque sélectionnée parmi la carboxyméthylcellulose sodique, la méthylcellulose (MC), l'hydroxypropylméthylcellulose (HPMC), l'hydroxyéthylméthylcellulose (HEMC), et l'hydroxyéthylcellulose (HEC) ; une troisième composition, qui est l'un quelconque parmi un latex de caoutchouc naturel, un latex de styrène-butadiène, et un latex de caoutchouc de nitrile-butadiène, et qui est introduite sous une teneur de 5 à 15 % en poids sur la base du TEV ; une quatrième composition, qui est l'un quelconque sélectionné parmi une base d'époxy, une base de vinyle, une base amino, une base méthacryloxy, et des matériaux à base de styryle, et qui est introduite sous une teneur de 1 à 3 % en poids sur la base du TEV ; et une cinquième composition, qui est l'un quelconque sélectionné parmi des liants minéraux de silicates modifiés obtenus par modification de silice colloïdale, d'un sol de silice ou d'un silicate, et qui est introduite sous une teneur de 0,1 à 5 % en poids sur la base du TEV.
(KO) 화학적으로 박리된 질석(CEV)사용하지 않고, 열적으로 박리된 질석(TEV)만을 단독 사용하고 이를 표층분리방법으로 제조하여 사용함에 따라서 입자를 한층 한층 분리시켜 사용함으로써 기밀성능이 극대화되고 균진화된 표면상태를 수득할 수 있는 가스켓 및 이의 제조방법이 개시되어 있다. 상기 목적을 달성하기 위해서 본 발명의 바람직한 일 실시 예에 따르면, 본 발명인 가스켓은 물과 혼합된 TEV를 표층분리방법으로 10~2000마이크로미터로 분리한 제1 조성물; 카르복시메틸셀룰오스나트륨(sodium carboxymethyl cellulose), MC(Methyl Cellulose), HPMC(HydroxyPropylMethyl Cellulose), HEMC(HydroxyEthylMethyl Cellulose) 및 HEC(Hydroxyethyl Cellulose)에서 선택된 어느 하나의 제2 조성물; 천연고무 라텍스, 스티렌부타디엔 라텍스, 니트릴 부타디엔 고무 라텍스에서 선택된 어느 하나로서 TEV를 기준으로 5~15wt%의 함량으로 투입되는 제3 조성물; 및 에폭시계, 비닐계, 아미노계, 메타크라이옥시계, 스트릴계에서 선택된 어느 하나로서 TEV를 기준으로 1~3wt%함량으로 투입되는 제4 조성물; 콜로이드 실리카(Colloidal Silica) 또는 실리카졸(Silica sol) 또는 규산염(Silicate)을 변형시킨 변성 실리케이트인 무기 바인더에서 선택된 어느 하나로서 TEV를 기준으로 0.1~5wt%의 함량으로 투입되는 제5 조성물로 이루어진다.
