Abstract

The invention provides a compound antimicrobial agent containing an inorganic antimicrobial agent and an organic antimicrobial agent, wherein the inorganic antimicrobial agent is metal salt and/or metallic oxides with antimicrobial activity; the organic antimicrobial agent is a composition the formation of which is shown in an above formula (I) and/or formula (II) and is one or several of pyridines, wherein R1 and R2 showed in the formula (I) and the formula (II) are alkyls with the number of hydrogen atoms or carbon atoms from 1 to 8. The invention also provides an antimicrobial coating composition containing the compound antimicrobial agent and antimicrobial coating materials using the antimicrobial coating composition. The compound antimicrobial agent is prepared by a very simple method and can achieve the very favorable antimicrobial effect by only simply mixing the inorganic antimicrobial agent and the organic antimicrobial agent of the compound antimicrobial agent.

Description

technical field [0001] The present invention relates to a kind of composite antibacterial agent and antibacterial coating composition and antibacterial coating material, more specifically, relate to a kind of composite antibacterial agent and the antibacterial coating composition containing this composite antibacterial agent and use this antibacterial coating combination antimicrobial coating material. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people have put forward higher requirements for the environmental quality and hygiene level they depend on for survival. At the same time, various pathogenic microorganisms are widely distributed in nature, and grow, reproduce, and even mutate under certain conditions, which not only cause corrosion and decomposition of materials, but also threaten human health. Thereby, the antibacterial product that can guarantee health to some extent is more and more s...
