Molded body for water-consuming equipment and method
Provided are: a molded article for water equipment, which is capable of suppressing molecular cleavage of polyamide due to the generation of radicals caused by a chlorine-based oxidizing substance contained in tap water for bactericidal use, and which is capable of suppressing deterioration in the performance of the molded article; the molded body for water equipment according to the present invention comprises a resin composition containing 10-200 parts by mass of an inorganic filler (B) and 0.1-2.0 parts by mass of a phenolic antioxidant (C) per 100 parts by mass of a semi-aromatic polyamide (A), the semi-aromatic polyamide (A) contains a dicarboxylic acid unit having an aromatic dicarboxylic acid unit as a main component and a diamine unit having an aliphatic diamine unit as a main component, and the phenolic antioxidant (C) has a structure represented by formula (1) in the molecule. (In formula (1), * * represents a bonding part. )
本发明提供用水设备用成形体等，其能够抑制因作为杀菌用途包含于自来水中的氯系氧化物质所引起的自由基的产生所致的聚酰胺的分子切断，进而能够抑制成形体的性能降低。本发明的用水设备用成形体包含树脂组合物，所述树脂组合物中相对于半芳香族聚酰胺(A)100质量份，以10～200质量份包含无机填充剂(B)且以0.1～2.0质量份的比例包含酚系抗氧化剂(C)，所述半芳香族聚酰胺(A)包含以芳香族二羧酸单元作为主成分的二羧酸单元、和以脂肪族二胺单元作为主成分的二胺单元，所述酚系抗氧化剂(C)在分子中具有下述式(1)所示的结构。(式(1)中，**表示键合部。)
