  A polyacetal resin composition comprises a polyacetal resin, and at least one carboxylic acid hydrazide selected from a saturated or unsaturated long-chain aliphatic carboxylic acid hydrazide, a saturated or unsaturated alicyclic carboxylic acid hydrazide, a dimer acid or trimer acid hydrazide, and an oxycarboxylic acid hydrazide corresponding to each of these hydrazides. The proportion of the carboxylic acid hydrazide may be about 0.001 to 20 parts by weight relative to 100 parts by weight of the polyacetal resin. The polyacetal resin composition may further comprise at least one member selected from an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, an impact resistance improver, a slip-improving agent, a coloring agent, and a filler. With the use of such a resin composition, stability of a polyacetal resin is improved, and formaldehyde emission is inhibited.

  聚缩醛树脂组合物由聚缩醛树脂和至少一种羧酸酰肼组成，羧酸酰肼选自饱和或不饱和长链脂族羧酸酰肼、饱和或不饱和脂环族羧酸酰肼、二聚酸或三聚酸酰肼以及与上述每种酰肼相对应的氧羧酸酰肼。相对于 100 重量份的聚缩醛树脂，羧酸酰肼的比例可以是约 0.001 至 20 重量份。聚缩醛树脂组合物还可以包含至少一种选自抗氧化剂、热稳定剂、加工稳定剂、耐候（光）稳定剂、抗冲击性改进剂、滑爽性改进剂、着色剂和填料的成分。使用这种树脂组合物可以提高聚缩醛树脂的稳定性，并抑制甲醛释放。

  An aldehyde-inhibiting composition inhibiting an aldehyde from an aldehyde-generating source comprises a carboxylic acid hydrazide and a metal salt of a hydroxy polycarboxylic acid (e.g., a salt of citric acid, malic acid, or tartaric acid with an alkaline earth metal) in a proportion of 0.01 to 100 parts by weight relative to 1 part by weight of the carboxylic acidhydrazide. Moreover, a polyacetal resin composition may comprise a polyacetal resin and the aldehyde-inhibiting composition in a proportion of 0.001 to 20 parts by weight of the aldehyde-inhibiting composition relative to 100 parts by weight of the polyacetal resin. To the resin composition, may be added an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, an impact resistance improver, a gloss control agent, a sliding improver, a coloring agent, a filler, and others. A small amount of the aldehyde-inhibiting composition efficiently inhibits the aldehyde generation from the polyacetal resin without discoloring the resin.

  一种抑制醛生成源的醛的抑醛组合物包括羧酸酰肼和羟基多羧酸的金属盐（如柠檬酸、苹果酸或酒石酸与碱土金属的盐），相对于 1 份羧酸酰肼的重量比例为 0.01 至 100 份。此外，聚缩醛树脂组合物可包括聚缩醛树脂和醛抑制组合物，其中醛抑制组合物的比例为 0.001 至 20（按聚缩醛树脂的重量计），相对于 100（按聚缩醛树脂的重量计）。在树脂组合物中可添加抗氧化剂、热稳定剂、加工稳定剂、耐候（光）稳定剂、抗冲击性改进剂、光泽控制剂、滑动改进剂、着色剂、填料等。少量的醛抑制组合物就能有效抑制聚缩醛树脂中醛的生成，而不会使树脂变色。
