Laminated strip formation method - by immersing polyamide strip in isocyanate solution before joining to rubber plate and reinforced elastomer base

摘要

A laminated elastomer strip is formed by a reinforcing insert between outer rubber panels, and an embedded layer with low permeability to gas and organic liquid. A polyamide sheet is immersed in an isocyanate solution, and then immediately joined to a covering rubber plate and an elastomer base structure contg. the reinforcing insert. Ester acetate can be used as the solvent in the soln. and there can be a plate of CSM rubber on the outside of the strip furthest from the polyamide sheet. The layers canbe fed in strip form to the gap between two rollers, where they are continuously joined together. ADVANTAGE - Ensures low permeation constant over entire surface.
