Benefits of technology

The present inventor's new compound called Potassium ZrC2O3 improves its effectiveness compared to previous methods by making them more effective at producing strong coatings on materials like papers that have been printed over for longer periods before being stored outdoors due to their ability to resist moist environments such as rainwater while still maintaining excellent print quality. This results in improved durability during use even after prolonged exposures under adverse conditions.

Problems solved by technology

The technical problem addressed in this patented text relates to finding new materials capable of reducing environmental impact without compromising their effectiveness on certain properties like moisture retention performance when applied onto paper during printing processes.

Abstract

The invention discloses a potassium-zirconium-carbonate cross-linking water-resistant agent and a preparing method thereof. The preparing method includes the following steps that water is added into potassium carbonate, and a potassium carbonate solution is prepared; the potassium carbonate solution is heated to 20 DEG C to 70 DEG C; under the stirring effect, zirconium basic sulfate is added intothe potassium carbonate solution, and the mass ratio of the zirconium basic sulfate to the potassium carbonate is 1:(0.47-0.8); the mixture is reacted for 0.5 h to 8 h, then filtering is carried out,and the obtained filtrate is the potassium-zirconium-carbonate cross-linking water-resistant agent. Potassium zirconium carbonate has high chemical activity, solidification is easy when the potassiumzirconium carbonate serves as a water-resistant cross-linking agent of a paper coating, coating solidification is rapid, and paper products have good water resistance without long-term storage or multi-section drying after machine discharging; coated paper has good comprehensive performance in the multiple aspects such as whiteness, printing glossiness, humidity resistance, abrasion resistance, anti-dry napping strength and anti-wet napping strength.
