<p>The method for bonding polyolefin plastic materials, omopolymers, copolymers, either thermoplastic or cross-linked, expanded or not expanded, alone or properly compounded with plasticizers, extender, fillers, mineral or organic fibres, stabilizers, chemical additives, includes the application of a coat of a solution containing 0.5 % up to 10 % of a chlorinated organic compound dissolved into an organic solvent, blend in the ratio of 99.5 % to 90 %; a first evaporation of solvents contained in the solution; the exposure of the surface treated with the solution to ultraviolet radiations; the subsequent cooling; the application of an adhesive in solution of organic solvents or in water dispersion onto the polyolefin plastic material prepared as above and onto another material to be bonded thereto, followed by a second evaporation of organic solvents contained in the adhesive, or the application of melted non volatile adhesive onto the polyolefin plastic material and onto another material to be bonded thereto; the coupling of said materials applying pressure.</p> |
