preparation example Construction

[0046] The preparation method of the nano antibacterial and antifungal coating: under normal environment and the stirring condition that the stirring speed is 350-400 rpm, mix the acrylic resin, polyester resin and organic solvent in the reaction tank evenly, and then Add nano-inorganic nano-antibacterial agent and anti-mildew additive into the reaction tank to make the ingredients mix and disperse evenly, and finally add the curing agent into the reaction tank and mix evenly to form the nano-anti-bacterial and anti-mold coating.

[0047] Described cleaning comprises the following specific steps:

[0048] a. Decontamination and derusting spray;

[0049] b. The first water spray;

[0050] c. Bright passivation treatment;

[0051] d, the second water spray;

[0052] e. Drying treatment: Automatically dry at a constant temperature for 15-20 minutes under water vapor at a temperature of 130 degrees Celsius, and the error range of the temperature of 130 degrees Celsius is controll...

Abstract

The invention provides a production technology for a nano antibacterial and mouldproof metal coin. The production technology is used for conducting antibacterial and mouldproof treatment on the wholesurface of a metal coin body. The production technology sequentially comprises the following steps including coating blending, cleaning, adhesion coating spraying, nano antibacterial and mouldproof coating spraying and curing. During coating blending, a mouldproof and antibacterial nano antibacterial and mouldproof coating is blended. During cleaning, the whole surface of the metal coin is subjected to automatic dirt removal spraying treatment. During adhesion coating spraying, adhesion coating spraying is conducted on the whole surface of the cleaned metal coin, and an adhesion layer is formed. During nano antibacterial and mouldproof coating spraying, after at least 3 min since spraying of the adhesion coating is finished, the whole surface of the metal coin is subjected to nano antibacterial and mouldproof coating spraying, and a nano antibacterial and mouldproof layer is formed. During curing, the metal coin to which the nano antibacterial and mouldproof coating is sprayed is conveyed into a high-temperature curing area, and drying is conducted for 30-50 min in the environment at the temperature ranging from 150 DEG C to 300 DEG C.

Description

technical field [0001] The invention relates to the technical field of production technology, in particular to a production technology of nanometer antibacterial and mildew-proof metal coins. Background technique [0002] Ordinary metal coins are used for market circulation and collection commemoration. The surface has no anti-mildew, anti-rust, anti-bacterial and anti-bacterial functions. After a long time of use, defects such as yellow spots, mildew spots, and rust will appear; No antibacterial and antibacterial function. [0003] In particular, the metal coins circulating in the market should be paid enough attention to antibacterial and antibacterial. Usually, the circulation of metal coins is through direct contact with human hands; however, in daily life, people's hands directly and frequently touch objects, and the skin There are various microorganisms such as bacteria and viruses on the skin, among which the skin folds and fingertips are the most. Scientific experi...
