Problems solved by technology

However, in the preparation process of inorganic non-metallic nano-antibacterial agents, the agglomeration of inorganic non-metallic nano-fillers is a very serious problem, because the agglomeration of nanoparticles will make them lose their unique nano-size effect and corresponding antibacterial function.

Abstract

The invention discloses a nano-antibacterial epoxy resin coating for a stainless steel water supply pipe and a preparation method and application thereof. According to the preparation method, an ultrasonic dispersion treatment method and an inorganic non-metal nano-filler surface modification method are combined, so inorganic non-metal nano-filler is always kept in a nano-size dispersion state, the agglomeration phenomenon of the inorganic non-metal nano-filler in the subsequent production process of preparing the nano-antibacterial epoxy resin coating is prevented, and the nano size effect and the corresponding antibacterial property of the nano-antibacterial epoxy resin coating are maintained. The nano-antibacterial epoxy resin coating prepared by the invention has the characteristics of high stability, good antibacterial effect, antibacterial durability, excellent broad-spectrum property, simplicity in production, convenience in use and the like; and the nano-antibacterial epoxy resin coating does not generate adverse effects on the performance of the stainless steel water supply pipe, and can also play a certain role in enhancing the corrosion resistance of the stainless steel water supply pipe.

Description

technical field [0001] The invention belongs to the field of stainless steel water supply pipes, and in particular relates to a nanometer antibacterial epoxy resin coating for stainless steel water supply pipes and its preparation method and application. Background technique [0002] Stainless steel pipe, as a profile with excellent mechanical properties and high chemical stability, has been widely used in papermaking, shipbuilding, nuclear industry, chemical industry and other industrial production as well as in all aspects of daily life. Stainless steel water supply pipe is its in life an important application. At present, the biggest problem in the practical application of water supply and drainage building materials is the secondary pollution of water quality. Generally speaking, the water from the waterworks meets the national drinking water quality standards, but after being transported by the main network and building branch pipes, end users often use "secondary poll...
