LAMINATE OF ABRASION-RESISTANT THERMOPLASTIC RESIN AND WEATHERPROOF RUBBER AND STICKING BONDING METHOD FOR MANUFACTURE OF SAID LAMINATE

摘要

PURPOSE: To obtain a laminate for a glass running strip of a vehicle window or the like by bonding a wear-resistant thermoplastic resin such as polypropylene or the like to a layer of a weather-resistant rubber such as an ethylene/ propylene/diene (EPDM) rubber without using an adhesive. CONSTITUTION: A glass running strip 10 includes an elastic gasket 12 and a wear-resistant strip 30 and the leg part 40 of window glass 42 is in contact with the polypropylene wear-resistant strip 30. The wear-resistant strip 30 is extruded through a crosshead die and brought into contact with the heated gasket 12 under pressure so as to be pressed together with the gasket 12. The inner layer formed along the bottom part of the wear-resistant strip coming into contact with the rubber or forming a boundary surface is melted by the high temp. of the extruded rubber or the heat generated by curing reaction. Cooling air is allowed to flow so as to cool the groove part of the glass running strip.
