Abstract

Abstract:

A quaternary ammonium salt type antibacterial resin was synthesized by the polymerization reaction. The antibacterial properties was evaluated by means of the bacteriostatic ring test, antibacterial rate test and the influence of different environment on the paint film antibacterial effect test, and the mechanical properties of antibacterial resin paint film were investigated. Results showed that the coating had good mechanical properties, when the content of quaternary ammonium salt was 6%, the antibacterial rate of paint film to the staphylococcus aureus and escherichia coli could reach more than 99%, and the coating had good resistance to bad environment, after wiping 1000 times, its antibacterial rate still more than 95%, and had good antibacterial effect performance.

Key words: quaternary ammonium salt, resin, antibacterial properties, paint film

摘要：

采用聚合反应合成了一种季铵盐型抗菌树脂,通过漆膜的抑菌圈测试、抗菌率测试以及模拟不同环境对漆膜抗菌效果的影响测试对抗菌树脂的抗菌性能进行了评价,并考察了抗菌树脂漆膜的力学性能。结果表明:季铵盐抗菌剂的含量为6%时,漆膜对金黄色葡萄球菌及大肠杆菌的抗菌率均能达到99%以上。在此含量下,对漆膜的力学性能影响不大,且漆膜具有良好的抵抗恶劣环境的能力,漆膜被擦拭1000次后,其抗菌率仍能达到95%以上,具有良好的抗菌持效性能。
