Foaming magnesium cement EPS particle grade A noncombustible board and preparation method thereof
The invention discloses a foaming magnesium cement EPS particle grade A noncombustible board. The foaming magnesium cement EPS particle grade A noncombustible board is characterized by being prepared from the following raw materials by weight: 80Kg of magnesium oxide, 5Kg of magnesium sulfate heptahydrate, 500g of nekal, 500g of calcium stearate, 10Kg of silicified straw fiber, 20Kg of hydroxyl mineral fibers, 18Kg of EPS particles, 500g of borax, 10Kg of nanofiber gypsum, 20Kg of sepiolite powder and 20Kg of magnesium chloride, wherein the silicified straw fiber is formed by spraying the mixed emulsion of sodium silicate and sodium chloride on the surface layer of the straw fibers for permeating. The preparation method comprises the steps of firstly adding water to the raw materials and stirring, secondly adding the nekal and stirring for foaming, and finally adding the EPS particles and stirring, injecting into a mold for molding, and curing at the normal temperature of 25 DEG C. The foaming magnesium cement EPS particle grade A noncombustible board prepared from the following raw materials is fireproof and thermal insulating, and reaches the fire protection glade A2. Besides, the board is good in thermal insulation properties, high in compressive strength and strong in adhesion stress.
