Problems solved by technology

However, poor water resistance limits its application
The commonly used water-resistant treatment method is to add hydrophobic polymers to flame-retardant coatings. This method is usually not conducive to the improvement of flame-retardant performance and the realization of multi-functionality
In addition, the common way to prepare flame-retardant luminous coatings is to mix flame retardants and long-lasting powders together. However, due to the pH problem of the flame-retardant system, the long-lasting powders usually fail, making the long-lasting powders unable to emit light or reducing brightness.

Embodiment 1

[0036] Weigh 55g of aluminum dihydrogen phosphate aqueous solution, 2g of zirconium phosphate, 2g of ammonium dihydrogen phosphate and 1g of titanium oxide into a container, stir at a speed of 600rpm for 1h, ultrasonically treat in an ultrasonic machine for 0.5h, and then stir at a speed of 600rpm 3h. After mixing evenly, slowly add 5 g of basic magnesium carbonate and 5 g of water while stirring to obtain the first mixed liquid with a viscosity of 15 Pa·s. Then stir at a speed of 100 rpm for 6 hours to mix the first mixed solution evenly and eliminate air bubbles to prepare a flame retardant coating. Weigh 12g of polyvinyl butyral and 5g of 1H,1H,2H,2H-perfluorodecyltrimethoxysilane and dissolve it in 50g of ethanol, raise the temperature to 80°C, add ammonia water drop by drop, and obtain a pH value of 8 The second mixed solution was stirred at a speed of 500rpm for 5h, cooled to room temperature, and the remaining ethanol and ammonia water were evaporated to obtain the pro...

[0038] Weigh 55g of magnesium dihydrogen phosphate liquid, 3g of zirconium phosphate, 2g of sodium polyphosphate, and 1g of alumina into a container, stir at a speed of 700rpm for 1.5h, then ultrasonically treat it in an ultrasonic machine for 1h, and then stir at a speed of 800rpm 2.5h. After mixing evenly, while stirring again, slowly add 7.5 g of basic magnesium carbonate and 6 g of water to obtain the first mixed liquid with a viscosity of 15 Pa·s. Then stir at a speed of 50 rpm for 6 hours to mix the first mixed solution evenly and eliminate air bubbles to prepare a flame retardant coating. 10 g of polyvinyl butyral and 4 g of trimethoxy-1H,1H,2H,2H-tridecafluoro-n-octylsilane were weighed and dissolved in 50 g of ethanol, and the reaction temperature was raised to 80°C. Then, ammonia water was added dropwise to the above solution mixture to obtain a second mixed solution with a pH value of 9, which was stirred at 400 rpm for 6 h, cooled to room temperature and the remai...

Abstract

The invention discloses a water-based inorganic flame-retardant luminescent coating, which comprises a flame-retardant coating and a luminescent coating; mixing a water-based flame-retardant binder, an inorganic flame retardant and an inorganic filler, stirring, ultrasonication, stirring and mixing, and adding an inorganic thickener Add the film-forming agent and water repellent to the first solvent, drop ammonia water, and get the second mixed solution with a pH value of 7-9; stir, cool to room temperature, and evaporate the remaining The first solvent and ammonia water are used to completely dissolve the product in the second solvent to obtain a third mixed solution; adding a coupling agent and long afterglow powder and stirring evenly to obtain a luminescent paint. The flame retardant coating in the coating has a more excellent flame retardant effect, which eliminates the high pollution problem caused by organic flame retardants, and causes less harm to the environment; the luminous coating makes the coating water resistant as a whole, and at the same time avoids The adverse effect of flame retardant coatings on long afterglow powder, when a fire occurs, can guide the direction of escape and reduce the loss caused by fire.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a flame-retardant luminous coating, in particular to a water-based inorganic flame-retardant luminous coating with water resistance and super-long afterglow functions and a preparation method thereof. Background technique [0002] In recent years, the frequent occurrence of severe fire accidents worldwide has brought huge threats to human life and property losses. Therefore, in the event of a fire, how to allow people to escape quickly and reduce economic losses has become a major challenge. It is conceivable that during a fire, the power system will often collapse. If you want to escape in the dark, you need luminous decorative materials to guide the direction and enable people to escape smoothly. At the same time, materials with flame retardant function can prolong the escape time and reduce economic losses. Therefore, coatings with both flame-retardant and luminescent functio...
