新型羽(毛)绒抗菌整理剂--季铵盐羟基硅乳复合物的制备及其性能

Preparation and properties of new feather antibacterial finishing agent-quaternary ammonium salt/hydroxy silicone emulsion compound

禽流感疫情在全球范围内愈演愈烈,使得羽(毛)绒及其制品的安全问题引起了材料研究工作者和消费者的广泛关注。目前羽(毛)绒行业主要采用巴式灭菌法,难以保证产品在储存、运输及使用过程中产生二次污染。用十二烷基二甲基苄基氯化铵(DDBAC)与羟基硅乳液的复合物对水洗羽(毛)绒进行浸渍、脱水、干燥。选取金黄色葡萄球菌为试验菌种,用营养肉汤稀释法和营养琼脂法测定羽(毛)绒样品的抗菌性能和耐洗涤性能。结果表明:当处理液中DDBAC的浓度为800μg/mL,羟基硅乳的浓度为4000μg/mL时,干燥温度为120℃、时间为10min时,羽(毛)绒样品经8次洗涤后,其对金黄色葡萄球菌的杀菌率仍然大于99%。

Bird flu spreads around the world,and then feather and its products security have caused wide attention for material research workers and consumers. Currently, the pasteurized method is mostly used in feather industry, but it is difficult to ensure the products not to be polluted secondly in the process of storage, transport and use. The feather washed down was treated with a compound of a dodecyl dimethyl henzyl ammonium chloride（DDBAC）together with a hydroxy sili con emulsion, then dehydrated and dried. The antibacterial property and washing resistance of the samples were determined using staphylococcus aureus via the nutrient broth dilution method and nutrient agar method. The results showed that the staphylococcus aureus sterilization rate of the samples washed 8 times was still greater than 99% at the concentration of 800μg/mL for DDBAC and 4000μ/mL for hydroxy silicone emulsion in the compound, and the drying temperature at 120 ℃ for 10minutes.
