Abstract

The invention discloses a high-efficiency silicon-nitrogen-phosphorus flame retardant as well as a preparation method and an application thereof, and also discloses a water-resistant transparent fireproof coating as well as a preparation method and an application thereof. The fireproof coating has excellent fireproof performance, outstanding water resistance, better wear resistance and aging resistance. Nitrogen-containing triglycidyl isocyanurate and phosphoric acid are introduced into the high-efficiency silicon-nitrogen-phosphorus flame retardant molecule, weakness of poor water resistanceof common ammonium polyphosphate is overcome, and water resistance and weather resistance of the water-based transparent fireproof coating are effectively improved. The fireproof coating is environmentally friendly, is convenient to construct, resource-saving and energy-saving, and adapts to the environment, and the problem about water resistance of the current water-based transparent fireproof coating is solved.

Description

technical field [0001] The invention relates to a high-efficiency silicon nitrogen phosphorus flame retardant, a water-resistant transparent fireproof coating and a preparation method and application thereof, belonging to the technical field of coatings. Background technique [0002] The current water-based fireproof coatings mainly have problems of weather resistance and water resistance. This kind of product has been randomly inspected by the national fireproof material quality inspection department, and the natural aging and accelerated aging tests are carried out respectively, and it is found that the fireproof performance is reduced to varying degrees and the physical and chemical properties are also reduced, and even some products appear pulverization, foaming and falling off. . At the same time, the problem of poor water resistance of the coating due to the poor water resistance of the expansion system in the current fire retardant coating components has not been ful...
