PURPOSE:To produce a metal-resin laminate rich in corrosion resistance and water resistance and hard to generate the release of a metal layer and a resin layer in high yield by adding a substance discharging water of crystallization at the time of melt bonding before silane modified polyethylene is bonded to the surface of a metal plate in a molten state. CONSTITUTION:A laminate is produced by bonding silane modified polyethylene to the surface of a metal plate. As silane modified polyethylene, a copolymer of ethylene and an unsaturated organosilane compd. or a substance obtained by grafting silane to polyethylene by kneading polyethylene, org. peroxide and an unsaturated organosilane compd. is used. As an additive added to the resin, ammonium aluminum sulfate dihydrate (discharge temp. of water of crystallization; 200 deg.C) is employed. When this resin is heated, water of crystallization is discharged from the additive and moisture is dispersed in silane modified polyethylene and silane modified polyethylene is homogenously hydrolyzed. |
