Abstract
A method for producing a laminate including a substrate and a rubber layer, the rubber layer having a thickness of 200 μm or more from the surface of the substrate, the method including contacting the substrate in a heated state with a polymer latex having a viscosity of 2,000 to 100,000 mPa·s at 25° C. to thereby coagulate the polymer in contact therewith to form the rubber layer.
Claims9
A method for producing a laminate comprising a substrate and a rubber layer, the rubber layer having a thickness of 200 μm or more from a surface of the substrate, the method comprising:
- contacting the substrate in a heated state with a polymer latex having a viscosity of 2,000 to 100,000 mPa·s at 25° C. to thereby coagulate the polymer latex in contact therewith to form the rubber layer, only once,
- wherein a polymer contained in the polymer latex is a nitrile rubber;
- the polymer latex contains a heat-sensitive coagulant;
- and
- the method does not include a step of contacting the substrate with a coagulant solution before contacting the substrate with the polymer latex.
