新型高效抗菌粉末涂料的研究

针对抗菌涂料在不同使用环境和高效抗菌性能的要求，从抗菌粉末涂料机理出发，研究了不同抗菌剂在不同工艺下制备的抗菌粉末涂层抗菌效果，并研究了不同抗菌剂在耐水洗涤、耐水煮、耐高温、耐紫外光照试验下对粉末涂层抗菌效果、光泽、色差的影响；同时研究了抗菌剂及其用量对涂层性能的影响。结果表明：添加带玻璃网状结构的银离子与锌离子复配的抗菌剂抗菌效果最佳；内挤搭配外混加入方式的粉末涂层的抗菌性能优异；得到的涂层在高温处理、水洗处理等条件下也具有良好的抗菌性能。选择含有玻璃网状结构的银离子的抗菌剂，涂层中的玻璃网状结构载体能缓慢地释放银离子，保证涂层的长效抗菌性能。

Research on New High-Efficacy Antimicrobial Powder Coatings

In view of the requirements of antimicrobial coatings in different use environments and high-efficacy antimicrobial properties,the antimicrobial effects of antimicrobial powder coatings prepared by use of different antimicrobial agents under different processes have been studied,and the influence of different antimicrobial agents in the test of water washing,water boiling,gloss and color difference,high temperature resistance and UV light resistance were also studied,as well as the effect of antimicrobial agent and its dosage on coating performance.The results showed that the antimicrobial efficacy of silver ion and zinc ion antimicrobial agents with glass network structure was the best.The powder coatings provided excellent antimicrobial performance by the internal extrusion and external mixing process.When the cured coatings was treated at high temperature,water washing,etc.,it remained good antimicrobial properties.When an antimicrobial agent with a glass network structure containing silver ions was used,the solver ions could be released slowly from the glass network structure,ensuring the long-term antimicrobial efficacy of the coatings.
