Embodiment 1

[0016] See accompanying drawing 1,2, on the PET magnetic base material (1-6) that is 0.27mm in thickness, print antibacterial protective varnish (1-5), make antibacterial subway card: on PET magnetic base material (1-6 ) on the back white covert layer (1-3) with the designed pattern printing layer (1-4) printed by offset printing, after the pattern printing layer (1-4) is printed, dry it in an ultraviolet dryer, and print the surface The temperature is controlled at 80°C. After drying, the antibacterial protective varnish (1-5) is printed on the pattern printing layer (1-4) by offset printing, with a thickness of 4.0um±1.0, and then the printed card is dried in an ultraviolet dryer Dry, the surface temperature of the printed card is controlled at 80°C; on the PET substrate on the surface of the PET magnetic substrate (1-6), the designed pattern printing layer (1-4) is printed by offset printing, and the pattern printing layer (1- 4) After printing, dry in an ultraviolet dryer,...

Embodiment 2

[0018] See attached image 3 , 4 , on the PVC base material (2-1) that is 0.81mm in thickness, print antibacterial protection varnish (2-3), make antibacterial telephone card: on the two faces of PVC telephone card base material (2-1), use offset printing method Print the designed pattern printing layer (2-2). After the pattern printing layer (2-2) is printed, dry it in an ultraviolet dryer. The surface temperature of the printed card is controlled at 80°C. After drying, the pattern printing layer (2-2) Use offset printing to print antibacterial protective varnish (2-3), the thickness is 4.0um±1.0, after printing antibacterial protective varnish (2-3), then dry the printed card in an ultraviolet dryer Dry, the surface temperature of the printed card is controlled at 80°C.

Abstract

An antibacterial card features that an antibacterial transparent oil layer is printed on its both surfaces of suppressing bacteria by more than 64%. Said antibacterial transparent oil is composed of a protective transparent oil and the antibacterial nanoparticles which contains positive Ag ions (3.6%), Na (1.32%) and zirconium phosphate (95%).

Description

1. Technical field [0001] The invention belongs to the technical field of printing and can be applied to subway cards, telephone cards, bank cards, hospital visit cards, etc., especially related cards with antibacterial function requirements. 2. Background technology [0002] The current card is to print the designed pattern on the surface and back of PET magnetic material and PVC material, and then print protective varnish on the patterns on both sides with offset printing. Since the card body will be in contact with various people or objects during use, and there are tiny air holes on the outermost surface of the card body, it is very easy to adhere and breed bacteria, which will lead to the infection of various diseases. In recent years, with the development of society, various cards have been widely used. Cards as a medium for pathogen transmission have attracted more and more attention. How to prevent the spread of diseases has become an urgent problem to be solved. 3...
