Abstract
Disclosed is an anticorrosive coating paper and a method for manufacturing the paper. The paper includes a base material containing an anticorrosive agent, a film layer adhered to one surface of the base material and configured to provide a vaporization passage for the anticorrosive agent, and a reinforcing material layer adhered to the other surface of the base material. The method incudes punching a film and providing a film layer having a flow passage that provides a vaporization passage for an anticorrosive agent, adhering the film layer having the flow passage to one surface of a base material containing the anticorrosive agent, and adhering a reinforcing material layer to the other surface of the base material.
Claims28
Anticorrosive coating paper comprising:
- a base material containing an anticorrosive agent;
- a film layer adhered to one surface of the base material and having a flow passage that provides a vaporization passage for the anticorrosive agent;
- and
- a reinforcing layer adhered to the other surface of the base material.
A method for manufacturing anticorrosive coating paper, the method comprising:
- (a) punching a film and providing a film layer having a flow passage that provides a vaporization passage for an anticorrosive agent;
- (b) adhering the film layer having the flow passage to one surface of a base material containing the anticorrosive agent;
- and
- (c) adhering a reinforcing material layer to the other surface of the base material.
A method for manufacturing anticorrosive coating paper, the method comprising:
- (a) forming a film layer on one surface of a base material;
- (b) punching the base material having the film layer formed thereon to form a flow passage that provides a vaporization passage for the anticorrosive agent, and
- (c) adhering a reinforcing material layer to the other surface of the base material.
A method for manufacturing anticorrosive coating paper, the method comprising:
- (a) adding and processing a pore forming additive to a film base material to form a film layer having a flow passage that provides a vaporization passage for an anticorrosive agent;
- (b) adhering the film layer having the flow passage and one surface of a base material containing an anticorrosive agent to each other;
- and
- (c) adhering a reinforcing material layer to the other surface of the base material.
Anticorrosive coating paper in which a base material containing an anticorrosive agent and a first reinforcing material layer are laminated and formed with an adhesive layer therebetween, wherein the adhesive layer comprises a mesh-like structure or a stripe structure.
A coating method for forming a resin coating layer on one surface of a base material, the coating layer being formed by 1) extruding a resin on one surface of the base material through a T-die method and thermally adhering the resultant or 2) manufacturing a resin in a sheet shape by extruding the resin through the T-die method and then laminating the base material and the sheet,
- wherein an additive that forms a huge pore at a temperature of the extrusion is added to the resin to form the coating layer with a mesh-like structure.
A coating method for forming a resin coating layer on one surface a base material, the coating layer is formed by 1) extruding a resin on one surface of the base material through a T-die method and thermally adhering the resultant or 2) manufacturing a resin in a sheet shape by extruding the resin through the T-die method and laminating the base material and the sheet,
- wherein the coating layer with a mesh-like structure is formed in a condition that a temperature of the extrusion is 250-450° C.
