Problems solved by technology

[0003] So far, there are roughly four types of water-based flame retardant fluids: (1) The liquid composite system based on hydrated sodium silicate has the advantages of low cost, no aldehyde pollution, and the ability to form an inorganic film on the surface of the flame retardant. However, the weather resistance of this system is relatively poor, which shows that the cured flame retardant coating is prone to pan-alkali and brittle and cracks when it is damp; (2) a liquid composite system based on ammonium polyphosphate and amino resin, and the amino resin is mainly urea-formaldehyde resin , melamine resin or phenol or melamine modified products of the above resins. This kind of flame retardant liquid has the advantages of wide sources, good flame retardant performance, and high cost performance, but it contains aldehydes, which cause volatile pollution and contact toxicity. (3) Liquid composite system based on ammonium polyphosphate and non-aldehyde resins such as water-based polyurethane and / or water-based acrylic acid; (4) Liquid composite system based on ammonium polyphosphate and inorganic silicon, boron or rare earth compounds
The latter two types of flame retardant liquids have the advantages of being green, harmless or low-toxic and pollution-free, but they not only have complicated preparation processes and high application costs, but also cannot exert ideal flame-retardant effects in most occasions, and often need to be combined with other System synergies
