INTEGRAL MOLDINGS OF POLYAMIDE RESIN, PROCESS FOR PRODUCTION THEREOF, AND JOINTING AID FOR POLYAMIDE RESIN

摘要

To provide a polyamide resin integrally molded product having high joining strength and excellent joining reliability, and a method for manufacturing the same, and also to provide a joining auxiliary capable of mutually joining polyamide resins with high joining strength. In manufacturing the polyamide resin integrally molded product by applying the joining auxiliary to a joint site of a polyamide resin molded product and welding a different polyamide resin which is to form an additive molded product part to the joint site, the joining auxiliary contains trihydroxybenzene and/or trihydroxybenzoic acid as a component (A) and an organic solvent which is capable of dissolving or dispersing the component (A) as a component (B). At this time, it is preferable for the component (A) to further contain dihydroxybenzene and/or dihydroxybenzoic acid.
