| titleOfInvention | A kind of polystyrene foam fire retardant and preparation method thereof based on nano magnesia |
| abstract | The preparation method of the present invention provides a kind of polystyrene foam fire retardant based on nano magnesia, it is characterized in that, described method includes following steps: (1) nano magnesia and organo silane coupling agent being added in sodium silicate solution, stirring forms magnesium-based suspension I；The nano magnesia partial size is 20nm~300nm, purity > 95.0%；(2) organic solvent is added into magnesium-based suspension I, stirring forms magnesium-based suspension II；(3) granules of polystyrene is added into magnesium-based suspension II, stirring forms polystyrene slurry；(4) by step (3) gains in 105~210 DEG C of temperature, 0.1~0.3MPa of pressure, 10~60min is handled, forms the polystyrene foam with flame retardant property.Composition of raw materials of the present invention is simple, preparation process is simply easy to implement, and resulting materials of the present invention have good oxygen index (OI) and pull strength, and the combustion rating of resulting materials of the present invention is A1 grades. |
