Title:
RECYCLED POLYAMIDE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/024846
Kind Code:
A1
Abstract:
The present invention relates to a recycled polyamide resin composition obtained by melt kneading a polyamide resin (a) or a polyamide resin composition (A) containing a polyamide resin (a) as the main component, polyamide resin waste (B), and a fibrous reinforcing filler (C), wherein the polyamide resin waste (B) contains a polyamide resin (b1) and a thermoplastic resin (b2) other than a polyamide resin; when the total of the polyamide resin (a) and the polyamide resin (b1) is taken to be 100 mass parts, the content of the polyamide resin (b1) is 11.0 mass parts or more; when the content of the polyamide resin (a) and the polyamide resin (b1) is taken to be 100 mass parts, the content of the thermoplastic resin (b2) other than a polyamide resin is 0.13 mass part or more; and the polyamide resin (a) or the polyamide resin composition (A) containing the polyamide resin (a) as the main component is 0 to 80.0 mass% and the fibrous reinforcing filler (C) is 5.0 to 70.0 mass% in 100 mass% of the recycled polyamide resin composition. The recycled polyamide resin composition of the present invention can contribute to SDGs (sustainable development goals).
