Antibacterial and antifouling metro IC (integrated circuit) card

Abstract

The invention discloses a preparation method of a nanometer composite UV (ultraviolet) printing ink with the antibacterial and antifouling functions, and a metro IC (integrated circuit) card of which two sides are respectively coated with a protecting film by the printing ink in a rolling way. The preparation method of the nanometer composite UV printing ink with the antibacterial and antifouling functions comprises the steps: adding a transparent nanometer TiO2 / ZnO composite material with the weight ratio of 5%-8% into the colorless UV printing ink special for the printing of the IC card, wherein the composite material has the proportion that TiO2: ZnO=3: 1; rising the temperature to 50-60 DEG C, and evenly stirring at a high speed of 2000 revolutions / MIN to obtain the nanometer composite modified UV printing ink; and standing at the normal temperature to use. After the existing mature technology is used, the preparation technology of the nanometer UV composite modified transparent printing ink is simple; and the IC card with the antibacterial and antifouling functions can be obtained by the steps of printing the two surfaces of the IC card, coating two ultra-thin protecting coatings on the two sides in a rolling way, and UV solidifying.

Description

technical field [0001] The invention relates to the field of preparation of UV ink for nanocomposite antibacterial and antifouling printing, in particular to an antibacterial and antifouling subway IC card made by rolling coating film of nanocomposite UV ink. Background technique [0002] With the rapid development of the subway across the country, the automatic fare collection (AFC) system of the subway has been widely used in various places. In 2010, there were 2 billion people using the system in Beijing alone, and the number of tickets purchased using self-service machines accounted for the total number of tickets purchased. 49.06% of the total amount, followed by a series of problems such as the spread of bacteria caused by the repeated use of IC truck tickets by multiple people, and the damage to the equipment of the ticket checking system due to ticket surface pollution. Every year, the subway company uses it to disinfect and clean the tickets. It takes a lot of manpo...

[0002] With the rapid development of the subway across the country, the automatic fare collection (AFC) system of the subway has been widely used in various places. In 2010, there were 2 billion people using the system in Beijing alone, and the number of tickets purchased using self-service machines accounted for the total number of tickets purchased. 49.06% of the total amount, followed by a series of problems such as the spread of bacteria caused by the repeated use of IC truck tickets by multiple people, and the damage to the equipment of the ticket checking system due to ticket surface pollution. Every year, the subway company uses it to disinfect and clean the tickets. It takes a lot of manpower and material resources to maintain equipment, etc., which not only increases the operating cost, but also the spread of bacteria will inevitably bring a lot of impact to people's daily life. Based on the above situation, an IC card subway ticket with antibacterial and antifouling capabilities is developed. It will inevitably bring huge social and economic benefits
