Description

technical field [0001] The invention relates to an antibacterial ink modified with cerium and gelatin and a preparation method thereof, belonging to the field of painting and calligraphy utensils. Background technique [0002] The four treasures of the Chinese study are divided into pen, ink, paper, and inkstone. As one of them, ink has a single color, but it has a variety of creative techniques. It plays a very important role in the field of Chinese art and 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, passed on and carried forward. [0003] At present, there are many inks for sale in the market, mostly made of carbon black, animal rubber, etc., which are perishable. In order to prevent the deterioration of the ink, toxic preservatives such as phenol are added to prolong the storage time of the ink. And the addition of this type of preservative not only...
