Abstract
Official abstract text for this publication.
A material for gaskets is disclosed, wherein a metal surface coating layer, a primer layer and a rubber layer are formed, or a metal surface coating layer and a rubber layer are formed on at least a part of one side or both sides of a substrate formed of a metal plate sequentially from the metal plate side, and the metal surface coating layer comprises (A) one or more carbonates selected from the group consisting of Mg carbonate, Co carbonate, Zr carbonate, Mn carbonate, Ni carbonate, and Cu carbonate and (B) one or more selected from the group consisting of silica, alumina, zirconia, and titania.
First claim
Opening claim text (preview).
The invention claimed is: 1. A material for gaskets, comprising at least a substrate formed of a metal plate, a metal surface coating layer formed on one side surface or both side surfaces of the substrate, a rubber layer formed via the metal surface coating layer on the substrate, and a primer layer formed between the metal surface coating layer and the rubber layer, wherein the primer layer comprises a cured product of a phenolic resin or a cured product of an epoxy resin, wherein the rubber layer is formed in a portion in contact with engine coolant, and wherein the metal surface coating layer consists of (A) one or more carbonates selected from the group consisting of Mg carbonate, Co carbonate, Zr carbonate, Mn carbonate, Ni carbonate, and Cu carbonate and (B) one or more selected from the group consisting of silica, alumina, zirconia, and titania. 2. The material for gaskets according to claim 1 , wherein the rubber forming the rubber layer is a nitrile rubber. 3. The material for gaskets according to claim 2 , wherein the metal surface coating layer is a surface coating layer formed by applying a treatment liquid for forming the metal surface coating layer, the treatment liquid comprising (A) one or more carbonates selected from the group consisting of Mg carbonate, Co carbonate, Zr carbonate, Mn carbonate, Ni carbonate, and Cu carbonate and (B) one or more selected from the group consisting of silica, alumina, zirconia, and titania, to a surface of the substrate and then drying the treatment liquid. 4. The material for gaskets according to claim 1 , wherein the rubber forming the rubber layer is a Fluorocarbon Rubber. 5. The material for gaskets according to claim 4 , wherein the metal surface coating layer is a surface coating layer formed by applying a treatment liquid for forming the metal surface coating layer, the treatment liquid comprising (A) one or more carbonates selected from the group consisting of Mg carbonate, Co carbonate, Zr carbonate, Mn carbonate, Ni carbonate, and Cu carbonate and (B) one or more selected from the group consisting of silica, alumina, zirconia, and titania, to a surface of the substrate and then drying the treatment liquid. 6. The material for gaskets according to claim 1 , wherein the metal surface coating layer is a surface coating layer formed by applying a treatment liquid for forming the metal surface coating layer, the treatment liquid comprising (A) one or more carbonates selected from the group consisting of Mg carbonate, Co carbonate, Zr carbonate, Mn carbonate, Ni carbonate, and Cu carbonate and (B) one or more selected from the group consisting of silica, alumina, zirconia, and titania, to a surface of the substrate and then drying the treatment liquid.
