摘　　要：通过在聚甲醛材料中复配脱挥剂、抗氧剂、光稳定剂、甲醛捕捉剂及甲酸吸收剂等助剂,制备出了一种低甲醛释放量的聚甲醛材料,采用VDA275标准对所制得的材料进行了甲醛释放量测试分析,并测试了其主要的力学性能。结果表明,所制得的聚甲醛材料甲醛释放量较低,并且其主要力学性能几乎没有变化。The polyformaldehyde material with low formaldehyde emission was prepared polyoxymethylene with additives such as devolatilization agent, antioxidant agent, through blending light stabilizer, formaldehyde scavenger and formic acid absorbent agent. The amount of formaldehyde emission of the resultant material was analyzed using the VDA275 standard, and the main mechanical properties were also tested. The results showed that the amount of formaldehyde emission of the prepared polyformaldehyde was low and its mechanical properties changed little.
