Acrylic fireproof coating and method of preparing

A method of preparing an acrylic polymer mixture for constituting a fireproof construction coating, the method comprising the steps of:

• providing 355 gallons of constituents including
• 75 gallons of water,
• 960 lbs of styrene acrylic polymer,
• 5 60 lb bags-300 lbs of refined white dolomite,
• 600 lbs of processed granite,
• 300 lbs of processed white marble,
• 2280 lbs of calcium sulfate,
• 17.5 lb of silicon concentrate 10 percent,
• 100 lbs of titanium dioxide,
• 52 lbs of polyethylene glycol,
• 52 lbs of butoxyethanol,
• 52 lbs of light mineral spirits,
• 0.75 lbs of nonporous silica microspheres, and
• 90 lbs of phosphorus trichloride PCl 3;
• heating the water to 70 degrees Celsius and adding the calcium sulfate at low speed, adding half of the dolomite at low speed leaving a remaining half, heating the acrylic and silicon to 135 degrees, adding the mineral spirits at high speed, adding the titanium dioxide at high speed, adding half of the marble and granite leaving a remaining half;
• adjusting the temperature of the heated constituents to 50 degrees Celsius and adding the remaining half of the dolomite at high speed, adding the butoxyethanol at high speed, adding half of the polyethylene glycol at high speed leaving a remaining half, adding half of the heated acrylic mix leaving a remaining half;
• and
• blending the blended constituents at high speed until the temperature cools to ambient and adding the remaining half of the polyethylene glycol at high speed, adding the remaining half of the acrylic mix when cooled to 80 degrees Celsius, adding the phosphorus trichloride PCl 3 at medium speed, and adding the remaining half of the marble and granite at medium speed.
