Title:
POLYAMIDE RESIN COMPOSITION, POLYAMIDE RESIN COMPOSITION FOR THREE-DIMENSIONAL MODELING, AND THREE-DIMENSIONAL MODEL OF SAME
Document Type and Number:
WIPO Patent Application WO/2023/008480
Kind Code:
A1
Abstract:
The present invention relates to a polyamide resin composition which contains 60% by mass to 95% by mass of a polyamide resin (A) and 5% by mass to 40% by mass of a novolac type phenolic resin (B) in 100% by mass of the polyamide resin composition, wherein: the polyamide resin (A) has a relative viscosity of 1.9 to 5.0 as determined at 25°C in accordance with JIS K6920-2; the novolac type phenolic resin (B) has a softening point temperature of 130°C or less; and the extract fraction after subjecting the polyamide resin composition to 6-hour extraction by means of a Soxhlet extraction method that uses water as a solvent is 1.5% by mass or less relative to 100% by mass of the polyamide resin composition used for the extraction. The present invention also relates to: a polyamide resin composition which contains 30% by mass to 70% by mass of a polyamide resin (A), 10% by mass to 40% by mass of a novolac type phenolic resin (B) and 5% by mass to 40% by mass of a reinforcement filler (C) in 100% by mass of the polyamide resin composition; and a polyamide resin composition for three-dimensional modeling, the polyamide resin composition containing 60% by mass to 95% by mass of a polyamide resin (A) and 5% by mass to 40% by mass of a novolac type phenolic resin (B) in 100% by mass of the polyamide resin composition for three-dimensional modeling.
