环保新型无氨保鲜剂在无氨胶乳制备中的应用

Application of Environment-friendly New Ammonia-free Preservative in Preparation of Ammonia-free Latex

研究环保新型无氨保鲜剂在无氨胶乳制备中的应用。结果表明:新型无氨保鲜剂可溶于水,不易挥发,使用时无臭味和刺激性气味;使用鲜胶乳质量分数0.02的新型无氨保鲜剂即可保证鲜胶乳48 h内不变质;新型无氨保鲜剂与促进剂TMTD/氧化锌复合用于浓缩胶乳中,保存效果好。使用新型无氨保鲜剂可减少环境污染,改善工作条件。

The application of environment-friendly new ammonia-free preservative in the preparation of ammonia-free latex was investigated.The results showed that new environment-friendly ammonia-free preservative was soluble in water,was not volatile,and had no odor or irritating smell.The fresh latex did not deteriorate within 48 h by using new ammonia-free preservative with addition level of 0.02 mass fraction of fresh latex.The ammonia-free preservative/accelerator TMTD/zinc oxide had good preservation effect in the concentrated latex.The use of new ammonia-free preservative could reduce environmental pollution and improve working conditions.
