Title:
ポリアセタール樹脂組成物及びポリアセタール樹脂成形品
Document Type and Number:
Japanese Patent JP6529373
Kind Code:
B2
Abstract:
Disclosed is a polyacetal resin composition having a dihydrazone compound (B), which is composed of at least one selected from the group consisting of a dihydrazone compound (B1) represented by the following general formula (1) and a dihydrazone compound (B2) represented by the following general formula (2), blended at a ratio of 0.02 to 5 parts by mass, a polyamide resin (C) blended at a ratio of 0.01 to 3 parts by mass, and a coloring agent (D), which is composed of at least one selected from the group consisting of an inorganic coloring agent and an organic coloring agent, blended at a ratio of 0.01 to 5 parts by mass relative to 100 parts by mass of a polyacetal resin (A). The polyamide resin (C) is a polyamide resin which has at least one physical property of i) a physical property that the melting point or the softening point is not higher than 180°C and ii) a physical property that the amine value is not lower than 2 mgKOH/g:
(in the formula, R 1 represents an aliphatic hydrocarbon group with carbon atom number of 4 to 19, an alicyclic hydrocarbon group with carbon atom number of 6 to 10, or an aromatic hydrocarbon group with carbon atom number of 6 to 10. R 2 to R 5 each represent a methyl group)
(in the formula, R 8 represents an aliphatic hydrocarbon group with carbon atom number of 4 to 19, an alicyclic hydrocarbon group with carbon atom number of 6 to 10, or an aromatic hydrocarbon group with carbon atom number of 6 to 10. R 6 and R 7 each independently represent an alicyclic hydrocarbon group with carbon atom number of 3 to 12).
