Problems solved by technology

Among the flame retardants that have been developed so far, halogen-based products, namely bromine and chlorine-based products, are widely used, but this type of flame retardant has a great disadvantage: it reduces the UV stability of the flame-retardant substrate, When the flame-retardant substrate is burned, more smoke, corrosive gas and toxic gas will be generated, causing pollution and harm to the surrounding environment
The biggest problem with traditional water-based flame retardants is that most substances are not water-soluble. For this reason, dispersants and anti-sedimentation agents have to be added to make the surface of the treated product opaque and serious crystallization, which greatly affects the The surface quality of the product, and some components have serious hygroscopicity, which has a greater impact on the mechanical properties of the product; in addition, some components are not degradable, which brings harm to the ecological environment
[0004] U.S. Patent No. 4,514,327 reports a formulation of a flame retardant liquid, including: ammonium sulfate, boric acid, bromic acid, and ammonium monohydrogen phosphate. Although this formulation can achieve Very good flame retardant effect, but the formula contains bromic acid, which may cause personal injury during construction and fire
U.S. Patent US5246652 reports a new type of flame retardant liquid formula, which is mainly composed of soluble boron compounds and resins, but the formaldehyde content in this formula is too high, causing harm to the environment
Similar patents, such as the flame retardant solution reported in US4725382, often require vacuum soaking when performing flame retardant treatment, which has the disadvantages of large equipment investment and long treatment cycle

Abstract

The invention provides a high-efficiency multifunctional water-base fire resistant fluid and a preparation method thereof. The high-efficiency multifunctional water-base fire resistant fluid is characterized by comprising the following raw materials in portion by mass: 10 to 20 portions of ammonium phosphate salts, 4 to 8 portions of boron compounds, 1 to 3 portions of tri-n-butylamine, 2 to 8 portions of glucose, 3 to 5 portions of tertiary amine, 3 to 5 portions of urea, 1 to 3 portions of penetrant, 1 to 2 portions of surfactant, 0 to 1 portion of softener and 40 to 80 portions of water. The high-efficiency multifunctional water-base fire resistant fluid has the characteristics of clearness, achromatism, transparency, neutrality, low smoke, non-toxicity, nonirritant, noncorrosiveness, low cost and high efficiency. Inflammable materials such as polyester-cotton blend, cotton fabrics, ribless corduroy, bourette, silk-ramie, knitgoods, canvases, paper sheets, cartons and the like with hygroscopicity become fire-resistant materials after being treated by the high-efficiency multifunctional water-base fire resistant fluid, and reach the fire-resistant B1 standard stated by the country. The high-efficiency multifunctional water-base fire resistant fluid can be widely used for top-grade indoor finishing such as curtains, carpets, wall paper, paper-based finishing, wooden furniture, ceiling and the like, simultaneously has the advantages of simple construction and low cost, is a new generation of high-tech environment-friendly product, and has wide market prospect.
