摘要：本课题研究从单因素实验入手，再进行复配实验，在配方基础上，试验多种油脂和乳化剂复配效果。期间通过肉眼观察体系乳化效果是否稳定均一，并结合稳态流变测试体系流变数据，确立最优配方。在优化后配方的基础上，加入具有抗菌效果的精油成分，反复尝试不同种类精油及不同精油比例对抗菌剂的整体影响。最终用抑菌圈法检测抗菌剂的抑菌效果。结果表明，当乳化剂选用Brij721和Brij72组合时，乳化性能最优良，且通过稳态流变测试，最终确立的配方流变曲线与市售样品接近；添加同比例精油，百里香精油比山苍子精油、牛至精油抑菌圈大，因此选取百里香精油。当百里香精油含量为5.0%时，其抑菌圈测量大小为选用精油比例中（1%、3%、5%）最高的。但是5%添加量的抗菌剂不稳定，平行组会出现抑菌圈大小不稳定的情况。综合考虑，百里香精油选用3%比例添加量最优。61785

Study on Preparation and properties of aromatic leather antibacterial agent

Abstract: This topic research from the single factor experiment, and then carries on the compound experiment, on the basis of the formula, the test of a variety of oil and emulsifier compound effect. Through the naked eye observation system is stable and uniform emulsion effect, and combined with the steady flow test system rheological data, to establish the optimal formula. In the optimized formula based, adding antibacterial effects of essential oil components and repeated attempts to the overall impact of the different kinds of essential oils and essential oils of different proportion of antimicrobial agents. Finally, the antibacterial effect of antibacterial agent was detected by the method of inhibition zone. The results show that when the emulsifier selection brij721 and Brij72 combination, emulsifying properties of the most excellent, and through the steady flow test, finally established the formula rheological curve and city sale samples close to; add the same proportion of essential oil, thyme oil is larger than Litsea cubeba oil and oregano essential oil of bacteriostatic ring. Therefore, selecting thyme essential oil. When the thyme oil content is 5%, the inhibition zone size measurement in the proportion of selection of essential oils (1%, 3%, 5%) is the highest. But the addition amount of 5% antimicrobial agents is not stable, the parallel group will appear the size of the inhibition zone is not stable. Comprehensive consideration, thyme oil selected 3% optimal amount ratio.
