High-antibacterial-property coating and preparation method thereof

By combining epoxy resin, inorganic nanofillers, silane coupling agents, and organic antibacterial agents in stainless steel coatings, an organic-inorganic synergistic antibacterial coating is constructed. By utilizing 1,3,5-triazine compounds and silver-loaded zirconium phosphate antibacterial agents, the problem of narrow antibacterial spectrum in existing coatings is solved, achieving broad-spectrum antibacterial and long-lasting antibacterial effects.

AI Technical Summary

Technical Problem

Existing antibacterial agents for stainless steel coatings often only work against specific types of bacteria, resulting in a narrow antibacterial spectrum that is difficult to meet the antibacterial needs in complex environments.

Method used

Using epoxy resin as the polymer matrix, a dense and stable coating structure is constructed by combining inorganic nanofillers and silane coupling agents. Inorganic and organic antibacterial agents are added to achieve synergistic antibacterial action between organic and inorganic agents. 1,3,5-triazine compounds are used to disrupt bacterial cell membranes, and silver-loaded zirconium phosphate antibacterial agents are combined to slowly release Ag+, achieving long-lasting antibacterial effect.

Benefits of technology

It improves the antibacterial properties and density of the stainless steel surface coating, has a broad-spectrum antibacterial effect and long-lasting antibacterial ability, and enhances the wear resistance and antibacterial durability of the coating.

Abstract

The invention relates to a high-antibacterial-property coating and a preparation method thereof. The high-antibacterial-property coating is prepared from the following raw materials in parts by weight: 35-40 parts of epoxy resin, 2-6 parts of inorganic nano filler, 0.5-1.5 parts of an inorganic antibacterial agent, 0.2-0.6 part of an organic antibacterial agent, 1-3 parts of a silane coupling agent, 8-12 parts of a curing agent, 3-5 parts of a diluent, 0.5-1.0 part of a defoaming agent, 0.1-0.3 part of a flatting agent and 50-100 parts of a solvent. The organic antibacterial agent is a 1, 3, 5-triazine compound. The antibacterial stainless steel surface coating has the effect of improving the antibacterial property of the stainless steel surface coating.
