    • A process of preparation of an antimicrobial powder coating composition comprising the steps: a) transforming a natural antimicrobial agent into a salt-form and micronizing the resulting antimicrobial salt into powder, b) mixing at least one of the natural antimicrobial salt together with at least one amino-reactive thermoplastic binder resin, c) subjecting the mixture to a melt compounding process at a temperature in a range of 80 to 230° C., at a residence time period in a range of 5 to 60 seconds, using at least one co-rotating twin-screw extruder with a soft screw design having conveying elements offering a high D/d ratio and having mixing forward kneading block elements, d) cooling the extrudate, and e) micronizing into powder particles. The process forms a powder coating composition containing a natural antimicrobial agent which results in high quality antimicrobial coatings showing a homogeneous distribution of the antimicrobial agent in the coating and a stable antimicrobial activity.
    • 一种制备抗微生物粉末涂料组合物的方法,包括以下步骤:a)将天然抗微生物剂转化为盐形式并将所得抗微生物盐粉碎成粉末,b)将至少一种天然抗菌盐与至少一起混合 一种氨基反应性热塑性粘合剂树脂,c)使该混合物在80-230℃的温度下,在5至60秒的范围内的停留时间内使用至少一种 同向旋转双螺杆挤出机,软螺杆设计具有提供高D / d比率的输送元件,并具有混合前捏合块元件,d)冷却挤出物,和e)将粉碎成粉末颗粒。 该方法形成含有天然抗微生物剂的粉末涂料组合物,其导致高质量的抗微生物涂层,其显示抗微生物剂在涂层中的均匀分布和稳定的抗微生物活性。
