Abstract
A method of manufacturing laminated panels or foils consisting of a lead sheet and a synthetic sheet by using lead alloyed with antimony and/or coating the lead sheet with an alloy of lead. Optionally a protective film serving as an adhesive may be applied onto the surface that is to be welded to the synthetic material. A novel compound material consisting of a lead sheet and a plastics sheet.
Claims2
In a method for manufacturing a laminate of a polymeric film composed of polyethylene or polyethylene-acrylic acid copolymer and a layer of lead, consisting essentially of marrying the film and lead layer together by passing them through nip rollers, the improvement which comprises said lead layer being coated with a layer of a tin-lead alloy having a tin content in excess of 25 percent, said alloy layer being coated with a protective and adhesive film of a plasticizer for the polymeric film in a diluent prior to being married to the polymer layer.
In a method for manufacturing a laminate of a polymeric film composed of polyethylene or polyethylene-acrylic acid copolymer and a layer of lead, consisting essentially of marrying the film and lead layer together by passing them through nip rollers, the improvement which comprises said lead layer being coated with a layer of a lead-antimony alloy, the amount of antimony being 0.6 to 6 percent, said alloy layer being coated with a protective and adhesive film of a plasticizer for the polymeric film in a diluent prior to being married to the polymer layer.
