为制订我国第一个食品容器内壁卫生标准,选用聚酰胺环氧涂料及其固化剂进行传统毒性研究。实验结果表明,固化剂经口LD_(50)大于15000mg/kg,蓄积系数大于5.3,实际为无毒及无蓄积,涂料浸泡水经90天实验及繁殖实验均未发现异常。此涂料可用于食品工业,但尚需在长期实践中观察对人体的慢性危害。 In order to develop the first domestic food container wall health standards, the choice of polyamide epoxy coating and curing agent for traditional toxicity studies. The experimental results showed that the LD50 of the curing agent was more than 15000mg / kg, the storage coefficient was greater than 5.3, which was actually non-toxic and non-accumulative. No abnormalities were found in the soaking and soaking water for 90 days. This coating can be used in the food industry, but it is still necessary to observe chronic harm to the human body in long-term practice.
