Abstract
PURPOSE: To shorten the time for connection by a method wherein a heat cross- linking bonding agent is placed as an intermediary between a polyurethane film and an unvulcanized rubber and then the sides of polyurethane and rubber are compressed into united states under heating respectively by a heat plate at the fixed temperature, thereby the pyrolysis of urethane being prevented.
CONSTITUTION: A polyurethane film layer 2 is formed on the release paper 1 and further coated with a heat cross-linking bonding agent 3, whereon an unvulcanized rubber 5 is placed. The laminate thus prepared is arranged between a lower die 4 heated up to 140°C and an upper die 6 heated to 160W190°C in such a manner that the layer 2 of polyurethane film is positioned on the side of the lower die and then is united under heat and pressure. By using the release paper 1 given projected and recessed patterns, the urethane layer can be patterned with ease. Since the lower die has low temperature, the pyrolysis of polyurethane is avoided, the bonding by baking can be performed in a short time, and a boot sole material free from wrinkle and exfoliation can be obtained.
