| 摘要 |
The present invention relates to a method for overmolding a polyamide component by means of a polyolefin matrix, the polyamide component having a melting point Tf, and the polyolefin matrix being made up of a mixture of at least one non-reactive aliphatic polyolefin and at least one polyolefin comprising a reactive function selected from among the anhydride family, said method comprising a step of overmolding the polyamide component by means of the polyamide matrix, said matrix being injected, in the molten state, onto the polyamide component, characterized in that the polyolefin comprising said reactive function is 5 to 20 wt.% of the aforesaid matrix and in that, prior to the step of overmolding said component by means of the matrix, at least the surface of said component is heated to a temperature in a range between (Tf -55)°C (degrees Celsius) and (Tf -20)°C. The invention also relates to a two-layer structure directly obtained by means of the aforementioned method. |
