Abstract
Provided are: a tire including: a tire frame; and a reinforcing metal cord member that is wound at least on the outer circumference of the tire frame, wherein at least a portion of the reinforcing metal cord member is coated with a coating composition via an adhesion layer that contains a polyamide-based adhesive and has a melting point of from 160° C. to 200° C., the coating composition containing at least one thermoplastic material selected from polyamide-based thermoplastic resins having a melting point of from 160° C. to 240° C. and polyamide-based thermoplastic elastomers having a melting point of from 160° C. to 240° C.; and a method of producing the same.
Claims23
A tire, comprising:
- a tire frame;
- and
- a reinforcing metal cord member that is wound on at least an outer circumference of the tire frame,
- wherein at least a portion of the reinforcing metal cord member is coated with a coating composition comprising at least one thermoplastic material selected from a polyamide-based thermoplastic resin having a melting point of from 160° C. to 240° C. or a polyamide-based thermoplastic elastomer having a melting point of from 160° C. to 240° C., and
- wherein the at least a portion of the reinforcing metal cord member is coated with the coating composition via an adhesion layer having a melting point of from 160° C. to 200° C. and comprising a polyamide-based adhesive.
A method of producing a tire, the method comprising:
- forming a tire frame;
- coating at least a portion of a reinforcing metal cord member with a coating composition comprising at least one thermoplastic material selected from a polyamide-based thermoplastic resin having a melting point of from 160° C. to 240° C. or a polyamide-based thermoplastic elastomer having a melting point of from 160° C. to 240° C., wherein the at least a portion of the reinforcing metal cord member is coated with the coating composition via an adhesion layer having a melting point of from 160° C. to 200° C. and comprising a polyamide-based adhesive;
- and
- winding the reinforcing metal cord member onto the tire frame,
- wherein the coating of the at least a portion of the reinforcing metal cord member with the coating composition is performed by extruding the coating composition from an extruder having a mold temperature that is not lower than the melting point of the adhesion layer and that is from 160° C. to 200° C.
