Problems solved by technology

Of course, such antibacterial efficiency is relatively low compared to the amount of metal particles used, and the resulting body may develop discoloration due to metal compounds mixed into the resin
Accordingly, the appearance of the body is deteriorated, and the commodity value is reduced

Embodiment Construction

[0022] Preferred embodiments and examples of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] figure 1 is a flow chart illustrating the antibacterial activity of the surface of a body by utilizing nanoscale metal particles according to the present invention. Such as figure 1 As shown, the method of the present invention comprises the operation step 100 of dispersing the nano-sized metal particles into the solution, the operation step 110 of applying the solution dispersed with the nano-sized metal particles to the body, and the operation step 120 of drying the coated body , and an operation 130 of heat treating the coated or dried body.

[0024]

[0025] In operation step 100, the nanoscale metal particles are added to a dispersion medium and dispersed therein, and a typical dispersion medium is a volatile solution such as water or ethanol.

[0026] The average particle size of the nano-sized metal particles is 50...

Abstract

The invention discloses a method for using nano-scale metal particles to make the surface of a body have antibacterial activity, comprising the steps of: coating the surface of the body with a volatile solution dispersed with nano-size metal particles with an average particle size of 500nm or less, wherein the The metal particles are randomly selected from the group consisting of silver, aluminum, copper, iron, zinc, cadmium, palladium, rhodium, and chromium, and based on the volatile solution, the concentration of the metal particles is between 100ppm-2000ppm treating the coated body at a temperature ranging from 50° C. to 150° C. to prevent deformation of the body; and depositing the nano-sized metal particles on the body.

Description

technical field [0001] The present invention generally relates to a method for using nanoscale metal particles to impart antibacterial activity to a body, and more particularly to a method for depositing nanoscale metal particles on a body, which is characterized in that the nanoscale metal particles are dissolved in an easily The volatilized solution forms a colloid solution coated on the surface of the body, and then the coated body is subjected to heat treatment. Background technique [0002] Those skilled in the art are well aware that household appliances require sanitation and cleaning. Typical appliances such as refrigerators, washing machines, vacuum cleaners, electric fans, dryers, air conditioners, electric frying pans, rice cookers, dishwashers, and disinfection cabinets , Microwave Ovens, Blenders, VTRs (Video Recorders), Televisions, etc. [0003] Generally, for the purpose of making the above-mentioned utensils have antibacterial activity, a method of heating ...
