Problems solved by technology

[0005] There are free calcium ions and hydroxyl groups on the surface of the carbonate powder. It is difficult for the existing fluorescent whitening agent products on the market to effectively bond with the surface ions or groups of the calcium carbonate powder or to adsorb on the surface, and lack the ability to effectively whiten and brighten. Multifunctional material with surface activated calcium carbonate powder filler

Embodiment 1

[0032] Add 20.5mmol cyanuric chloride to 250mL ice water and place in ice bath. Then 10mmol 4,4'-diaminostilbene-2,2'-disulfonic acid (DSD acid) and 200mL distilled water, Na 2 CO 3 The mixture was stirred at 0°C and reacted for 2h. Add 20mmol p-aminobenzenesulfonic acid, raise the temperature to 35°C, add dropwise 10% Na 2 CO 3 The aqueous solution maintained the pH of the system at 7, and the temperature was controlled for 8 hours. Then dropwise add 22mmol of diethylamino ethyl methacrylate and 11mL of acetone mixture, raise the temperature to 90°C, add dropwise 10% Na 2 CO 3 The aqueous solution maintained the pH of the system at 9, and the temperature was controlled for 10 h. The endpoint of the three-step reaction was monitored by thin-layer chromatography. Cool to room temperature, add 60 g of sodium chloride, stir, filter with suction, and dry in vacuum to obtain sodium tetrasulfonate ethyl methacrylate quaternary ammonium fluorescent whitening agent with a yield...

Description

technical field [0001] The invention relates to the technical field of fluorescent whitening agents, in particular to the synthesis and application of a sodium tetrasulfonate ethyl methacrylate quaternary ammonium fluorescent whitening agent. Background technique [0002] In my country's "12th Five-Year" new material development plan, the development of new materials that are coordinated with resources and the environment is taken as the main assessment index, and the problem of resource shortage is solved through the development of new materials. my country has formed a relatively complete material science and technology system, and has obvious resource advantages and technological advantages in some new material fields, but the overall independent innovation capability is still relatively weak, and there are still relatively few new material products and technologies with independent intellectual property rights. Especially the lack of innovation in the calcium carbonate po...
