Method of producing article having secondary part adhered to press-formed metal part

A method of producing an article having a structurally primary part formed of a metal sheet and a structurally secondary part adhered to the primary part with an adhesive, said method comprising the steps of:

• forming the primary part by press-forming of a metal sheet to which a solid lubricant containing polyacrylic acid as a principal component thereof is applied beforehand;
• applying an adhesive containing a nitrile rubber as a principal component thereof, said nitrile rubber having a high chemical affinity with said polyacrylic acid of said lubricant, to a surface of the press-formed primary part with said polyacrylic acid lubricant being retained thereon;
• and
• adhering said secondary part to the adhesive-applied surface of said primary part.

A method of producing an article having a structurally primary part formed of a metal sheet and a structurally secondary part adhered to the primary part with an adhesive, said method comprising the steps of:

• forming the primary part by press-forming of a metal sheet to which a solid lubricant containing polyacrylic acid as a principal component thereof is applied beforehand;
• applying an adhesive containing a polyurethane rubber as a principal component thereof, said polyurethane rubber having a high chemical affinity with said polyacrylic acid of said lubricant, to a surface of the press-formed primary part with said polyacrylic acid lubricant being retained thereon;
• and
• adhering said secondary part to the adhesive-applied surface of said primary part.

• forming the primary part by press-forming of a metal sheet to which a solid lubricant containing polyacrylic acid as a principal component thereof is applied beforehand;
• applying an adhesive containing a vinyl polymer as a principal component thereof, said vinyl polymer having a high chemical affinity with said polyacrylic acid of said lubricant, to a surface of the press-formed primary part with said polyacrylic acid lubricant being retained thereon;
• and
• adhering said secondary part to the adhesive-applied surface of said primary part.
