摘要
目的了解室内装潢涂料中挥发性化合物对人体的急性吸入毒性的强度,并为室内装潢涂料的安全性评价提供依据。方法选一次最大限度法,吸入染毒,染毒浓度为涂料45g均匀涂刷在30cm×100cm表面积为0.3m2的洁净牛皮纸表面,静式吸入染毒2h。结果本次所选的28种室内装潢涂料半数致死浓度LC50>150g/m3,实验未见动物死亡。结论毒性分级属实际无毒级。
Objective To understand the acute toxicity intensity of volatile indoor decoration coating materials to the humans and provide the basis for evaluation of the safety indoor decoration coating. Methods A maximum limit method was chosen in this test by breathing intoxication,45g decoration coating material was painted evenly in a 0.3 m2 surface area of dean kraft paper,static type inhaled in 2 hours. Results The LCt0 of the selected indoor decoration coating material was over 150 g/m3, and no animals were dead in this toxicity test. Conclusion Toxicity classification is at actual non-toxic level.
