Preparation method of inorganic modified polystyrene insulation board
The invention relates to a preparation method of an inorganic modified polystyrene insulation board. In the preparation method, magnesia cement slurry is modified by raw materials such as halogenide-resistant agent, gypsum powder, styrene-acrylic emulsion, hydroxypropyl methyl cellulose and the like, the defects of the magnesia cement are overcome, the intermiscibility with the polystyrene can be improved, when in osmosis of a vacuum suction filter, the modified magnesia cement slurry is uniformly permeated into the polystyrene insulation board by utilizing negative p ressure, then the magnesia cement slurry is sent to a maintaining room to be maintained at the temperature of 20 to 25 DEG C, magnesite cement uniformly fills polystyrene particles and is tightly combined with the polystyrene particles, and the magnesite cement is good in fire resistance, so that the polystyrene insulation board can reach a grade-A fire-resisting requirement.
