Problems solved by technology

[0005] ①The electroplating process produces environmental pollution, and when the chrome plating on the surface of the trolley comes into contact with human skin, it will also cause damage to the human body (especially children);
[0006] ②The electroplating coating is relatively thin, and the inner layer will be exposed and rusted under the condition of long-term use and frequent bumping;
[0007] ③Chrome plating on the surface of the trolley is easy to get dirty and will breed bacteria when in contact with human skin

Abstract

The invention discloses an antimicrobial nylon powder for a trolley coating and a preparation process of the antimicrobial nylon powder. The antimicrobial nylon powder for the trolley coating comprises the following components: a nylon resin, an antibacterial silver ion masterbatch, organic fillers, an adhesion promoting agent, a high-temperature resistant antioxidant, an ultraviolet stabilizer, a leveling agent and a nucleating agent, wherein the nylon resin is PA11 or PA12 or PA1012 or PA1212. The invention also relates to the preparation process of the antimicrobial nylon powder for the trolley coating. The invention has the beneficial effects that the antimicrobial nylon powder has a good antimicrobial effect and is a very good environment-friendly material, and the adhesion of the nylon coating and a trolley metal layer is good by adding the adhesion promoting agent to the antimicrobial nylon powder, so that a trolley can be protected for a long term.

Description

technical field [0001] The present invention relates to a kind of nylon powder, more particularly, the present invention relates to a kind of antibacterial nylon powder and its preparation method that are used for trolley coating. Background technique [0002] At present, supermarket trolleys are frequently used tools in daily life. They are used frequently and are prone to bumps during the process of carrying objects. Because the body of the trolley is welded with iron wire, the iron wire is made of carbon steel, and the surface layer of iron wire is exposed. Rust occurs, and contact with human skin is extremely harmful. [0003] In order to avoid such hazards, a thin protective layer is applied to the surface of the trolley to protect it. The current method used is to chrome-plate the surface of the trolley by electroplating; the characteristics of the current technology: this method can protect the surface of the trolley The effect of rust can protect the inner wire of t...
