Printing ink traceability production process method based on block chain

Abstract

The invention discloses a printing ink tracing production process method based on a block chain. The method comprises the following steps: mixing acetic acid with a water-based saturated polyester resin solution to obtain a first mixed solution; mixing beewax, the low-odor slow-drying emulsion and a defoaming agent to obtain a second mixed solution, and adding the second mixed solution into the first mixed solution for emulsification to obtain an emulsion; mixing the low-odor quick-drying emulsion, color paste and varnish to obtain a third mixed solution, adding the third mixed solution into the emulsion, and mixing to obtain the printing ink. Printing ink is poured and packaged in an ink packaging bag, and a product identification code and a production date are printed; and sending the product identification code and the production date to the block chain. The printing ink is not easy to fall off after being printed and is low in odor; meanwhile, manufacturers can inquire the batch ofprinting ink which goes wrong through block chain tracing, consumers can inquire whether the purchased printing ink belongs to the batch of printing ink which goes wrong or not through block chain tracing, and the manufacturers cannot maliciously tamper data due to the non-tamper characteristic of the block chain.

Description

technical field [0001] The present invention relates to the field of ink printing, in particular to a blockchain-based traceable production process for printing ink. Background technique [0002] At present, as people's requirements for products are getting higher and higher, manufacturers and merchants have higher and higher printing requirements for product surfaces in order to give people a visual impact to promote consumption, and the technical requirements for printing inks are also gradually improving. A good printing ink should not only have good printing adaptability and a suitable drying speed, but more importantly, it should have the advantages of low odor and not easy to fall off, so as to improve the consumer experience, but most of the existing printing inks are as high as Less than this high demand. At the same time, after the printing ink is produced, most manufacturers will directly fill and seal it with ink packaging bags, and then send it directly to the w...

Problems solved by technology

A good printing ink should not only have good printing adaptability and a suitable drying speed, but more importantly, it should have the advantages of low odor and not easy to fall off, so as to improve the consumer experience, but most of the existing printing inks are as high as less than this high demand

At the same time, after the printing ink is produced, most manufacturers will directly fill and seal it with ink packaging bags, and then send it directly to the warehouse for storage or directly to the store. In this way, once there is a problem with the printing ink, it is difficult to find out which batch of printing ink has the problem , cannot be traced to the source of the problem

[0003] At the same time, when the printing ink is poured and packaged, in order to avoid the exhaustion of the printing ink in the transparent container on the filling and packaging equipment used to hold the printing ink to be filled and packaged, the staff will always observe the amount of remaining printing ink in the transparent container, so that not only It increases the workload of the staff, and it is also prone to accidents such as damage to the perfusion package caused by staff mistakes

[0004] Moreover, after the ink packaging bag is filled and sealed, when the product identification code and production date are printed on the surface of the ink packaging bag by the ink printer, if the parameters such as the atmospheric pressure and air specific humidity of the environment where the ink printer is located change greatly, and the ink If the operating parameters and ink density of the printer are not adjusted adaptively, the printed product identification code and production date are prone to ink falling off
