This invention relates to the field of coating technology, specifically to a printing coating for colored paper and its preparation method. In the preparation process, this invention incorporates dithiol dihydroxyacetic acid to increase the crosslinking points of the system, and trimethylolpropane tris(2-methyl-1-azacyclopropane propionate) containing an unstable aziridine three-membered ring to improve the degree of crosslinking. It also introduces isoborneol methacrylate to reduce internal stress, effectively balancing the crosslinking density and volume shrinkage of the system, resulting in a coating with excellent adhesion. Furthermore, this invention adds the bifunctional monomer 1,6-hexanediol diacrylate to make the network structure more uniform and provide anti-photooxidation properties, making the system less prone to oxidative discoloration. The addition of tripropylene glycol diacrylate reduces the risk of yellowing caused by small molecule migration. Therefore, the coating obtained in this way has significant anti-yellowing effects, preventing color distortion of colored paper and maintaining the appearance stability of the colored paper.

This invention discloses a preparation process for a moisturizing, anti-damage, and nourishing nail gel, belonging to the field of nail gel preparation technology. The process includes the following steps: mixing and stirring flexible aliphatic polyurethane acrylate, epoxidized soybean oil acrylate, isoborneol acrylate, and tripropylene glycol diacrylate; adding 2,4,6-trimethylbenzoyl-diphenylphosphine oxide and stirring; sequentially adding alkyl phosphate, polydimethylsiloxane, and an organosilicon defoamer and stirring; adding modified hydrolyzed keratin and stirring; adding modified plant squalane and stirring; adding modified calcium lactate and stirring; and adding a functional agent and stirring to obtain a mixture. The mixture is then vacuum degassed and filtered using a filter to remove impurities, yielding a moisturizing, anti-damage, and nourishing nail gel. In this invention, modified plant squalane is added, which is completely compatible with the gel layer and can form strong hydrogen bonds with the nail surface, locking the moisturizing ingredients firmly between the nail surface and the gel layer, preventing evaporation and loss, and achieving long-lasting moisture retention.

A method can be used for preparing 1,2-propanediol, dipropylene glycol, and tripropylene glycol. The method involves reacting propene with hydrogen peroxide containing nitrate, in the presence of a catalyst mixture containing a phase transfer catalyst and a heteropolytungstate, in a liquid reaction mixture containing an aqueous phase with a maximum apparent pH of 6 and an organic phase. The method then involves separating the reaction mixture into an aqueous phase containing 1,2-propanediol, dipropylene glycol, tripropylene glycol, and nitrate and an organic phase. The method further involves recycling at least part of the separated organic phase to the reaction; hydrogenating the separated aqueous phase using a heterogeneous hydrogenation catalyst to provide a hydrogenated aqueous phase with a reduced nitrate content; and recovering 1,2-propanediol, dipropylene glycol, and tripropylene glycol from the hydrogenated aqueous phase by a sequential multiple-step distillation.
