Abstract

The invention relates to a cerium and gelatin modified antibacterial ink and a preparation method thereof. The antibacterial ink is prepared from the following ingredients in parts by weight: 10 parts of toner, 60 to 540 parts of a gelatin solution, 0.02 to 9 parts of cerium salt, 0.5 to 6 parts of an emulsifier, 1.5 to 15 parts of a wetting agent and 0.15 to 1.5 parts of spice. The ink prepared by the preparation method disclosed by the invention has the characteristics of excellent antibacterial property, no toxicity, no odor and suitability for wide popularization and application.

Description

Technical field [0001] The invention relates to an antibacterial ink modified by cerium and gelatin and a preparation method thereof, and belongs to the field of painting and calligraphy utensils. Background technique [0002] The four treasures of China’s study are divided into pen, ink, paper, and inkstone. Although one of them is ink, although it has a single color, it has a variety of creative techniques. It plays a very important role in the field of Chinese art painting. The history of use can be traced back to several Thousands of years ago. As an important representative of Chinese art, ink should be continuously improved, and then passed on and carried forward. [0003] At present, there are many inks sold on the market, which are mostly made of carbon black, animal glue, etc., which are perishable. To prevent the deterioration of the ink, toxic preservatives such as phenol are added to extend the storage time of the ink. The addition of this kind of preservatives not on...
