Title:
ポリアミド樹脂組成物、成形品およびポリアミド樹脂ペレットの製造方法
Document Type and Number:
Japanese Patent JP7120025
Kind Code:
B2
Abstract:
Provided is a polyamide resin composition capable of providing a molded article having an excellent wear resistance while maintaining a high mechanical strength; a molded article; and a method for manufacturing a polyamide resin pellet. The polyamide resin composition includes a polyamide resin and an inorganic filler, wherein the polyamide resin includes diamine-derived constituent units and dicarboxylic acid derived constituent units; 70 mol% or more of the diamine-derived constituent units are derived from 1,4-bis(aminomethyl)cyclohexane; a molar ratio of cis:trans of the 1,4-bis(aminomethyl)cyclohexane is from 35:65 to 0:100; 70 mol% or more of the dicarboxylic acid-derived constituent units are derived from an α,ω-linear aliphatic dicarboxylic acid having from 8 to 12 carbons; and the polyamide resin includes phosphorus atoms in a ratio of from 20 to 100 mass ppm and comprises calcium atoms so as to be phosphorus atoms:calcium atoms of 1:0.3 to 0.7 in a molar ratio.
