PRIMER COATING FOR OLEFIN RESIN-METAL BONDED STRUCTURE |
摘要 |
<p>An olefin resin-metal bonded structure having a desirable combination of high corrosion resistance and peel strength, which comprises a metal substrate and an olefin resin layer bonded together through a primer layer, said primer layer containing (A) an oxidized polyethylene having an oxygen content of 0.1 to 10% by weight, a saponification value of 2 to 200, a density of 0.90 to 1.2 and an average molecular weight of 1000 to 50000 and (B) a coating-forming base resin having a density higher by at least 0.1 than the oxidized polyethylene and containing a functional group selected from hydroxyl and carbonyl groups at a concentration of at least 1 meq/g, the mixing weight ratio of the oxidized polyethylene (A) and the base resin (B) being within the following range: (A) : (B) = from 0.2 : 99.8 to 45 : 55, wherein said primer layer has a multi-layer structure in which each of the concentrations of the oxidized polyethylene (A) and the base resin (B) is changed with respect to the thickness direction with a certain gradient so that the base resin (B) is distributed predominantly on the side of the surface of the metal substrate and the oxidized polyethylene (A) is distributed predominantly on the side of the surface of the olefin resin.</p> |
