Embodiment 1

[0042] Weigh sodium p-styrene sulfonate (NaSS), acryloyloxyethyltrimethylammonium chloride solution (DMAEA-Q) according to a certain molar ratio (500:593:1:1), N, N'- Methylenebisacrylamide (MBAA) and α-ketoglutaric acid (KA) synthesized an organic matrix that can introduce metal ions. The specific operation was as follows: Weigh 2.9055g DMAEA-Q, 2.6062gNaSS, 0.0039gMBAA and 0.0037gKA ( The ratio of the four is calculated according to the molar ratio and rounded off), mix the above and add distilled water to make it 10ml, put it in a 60°C water bath and stir continuously until it is completely dissolved. Drop the solution into the designated mold and irradiate it under a UV lamp for 12 hours to carry out light crosslinking. After the organic matrix is ​​formed, soak it in FeCl 3 solution (1mol / L, 50ml) for 3 days to make Fe 3+ C with organic matrix 6 h 5 o 3 S - Form a stable ionic bond, then soak it in Na 2 MoO 4 solution (1mol / L, 50ml) for 3 days to make MoO 4 2- an...

Abstract

The invention discloses a complex containing iron ions and molybdate ions, an organic matter matrix and a preparation method thereof. Sodium p-styrene sulfonate and acryloyloxy ethyl trimethyl ammonium chloride are used as monomers, N,N'-methylene bisacrylamide is used as a crosslinking agent, alpha-ketoglutaric acid is taken as an initiator, polymerization reaction is carried out under the catalytic action of ultraviolet light to obtain an organic matter matrix, then the organic matter matrix is sequentially soaked in a ferric ion solution and a molybdate solution for a long time, so that Fe<3+> and C6H5O3S<-> of the organic matter matrix form a stable ionic bond, MoO4<2-> and N,N,N-trimethyl ethyl ammonium ions (C4H11N<+>) form stable ion bonds, drying is carried out to obtain the complex containing iron ions and molybdate ions, and the complex is ground into powder for use. The preparation process is simple, the raw materials are low in price, and the prepared product is widely used, especially used as a flame-retardant smoke suppressant, and has excellent flame-retardant smoke suppression performance.
