Description

Manufacturing method of spray coating type flame retardant

1 is an embodiment of applying the invention to the structure.

Figure 2 is an exemplary cross-sectional view after applying the present invention to the structure.

The present invention is diluted and mixed with calcium chloride, water, silicon resin, sodium silicate, emalonic vinyl acetate resin castable refractory first, ammonium phosphate, silica gel, asbestos sand powder, white lime, diatomaceous earth stone powder, etc. The present invention relates to a method for producing a spray-coated nonflammable agent that has been provided with fire resistance and heat resistance in a fabric.

In the past, there were gypsum boards that were highly evaluated for their robustness and delicacy. However, in the process of construction, they had to be added after adding existing interior facilities. Plaster and wallpaper of commonly used synthetic resins are not easy to generalize, but they are easy to install in order to decorate internal facilities.However, in case of inadvertent fire, the dissipation of sulfurous acid cuts generated in the process of burning synthetic resins There was a defect that caused damage to life.

The present invention provides a non-flammable agent that can prevent the generation of toxic cutlet even if a fire occurs by flame retardant treatment without damaging or damaging when modifying the internal structure of the building to solve the conventional problems as described above. In order to shorten the spray coating work process quickly and economically beneficial as described in detail by the manufacturing process as follows.

[Step 1]

Calcium Choride Cacl ₂ 150g

Water (H ₂ O) 1800CC

By diluting well, the flame retardant of the present invention acts to prevent ignition during cracking and fire when spray coating and curing.

[Step 2]

Silicon Resins 200CC

Sodium silicate (Soidum Silicate NaO _n SiO ₂ XH ₂ O) 40CC

Polyvinyl Acetate Resins emulsion 250CC

To grind with a grinder with a rotation speed of 700-1000rpm to manufacture a drug with a particle size of 200-450 mesh.Adhesion is improved and the fire retardant layer is foamed by heat in case of fire.

Allow to form a fabric layer.

[Step 3]

Castable refractory 100g

Monomonium phosphate (NH ₄ H ₂ PO ₄ ) 300CC

30 g of silica gel SiO ₂ XH ₂ O

The mixture is pulverized into a powder having a particle size of 200-450 mash and then heated again to 800 ℃ -1000 ℃, mixed and melted to increase the heat resistance, and to suppress the occurrence of poisonous cutlet in the event of fire. do.

[Step 4]

Asbestos Sand Powder 30g Diatomaceous Earth 200g

White lime 1800g stone powder 600g

Mixed well and pulverized into a powder having a particle size of 200-450 mash, and then mixed with 10-20% of water and heated at a temperature of 800 ° C.-1200 ° C. for 3-6 hours and pulverized again to 200-450 mash to make earth powder. Blocks flames and provides excellent thermal insulation.

[Step 5]

In the first, second, and third steps, dilution and mixed foamed refractory agent were prepared and precipitated, and the mixture in the fourth step was mixed at an appropriate mixing ratio and heated to 100 ° C.-200 ° C. for 30 minutes to 1 hour. After 1 hour to 2 hours to precipitate while maintaining a temperature of 30 ℃ -80 ℃.

At this time, if the dye is added in an appropriate amount, the flame retardant of the present invention can be colored.

The non-flammable agent (2) of the present invention manufactured through the manufacturing process as described above does not destroy the structure, non-combustible when sprayed to the automatic control injector (3) to form an appropriate layer anywhere in the structure (1), such as wood or wallpaper The layer (4) immediately turns into a solid gypsum board-like property and hardens. For a more visual harmony, the water-based paint (5) can be used to color aesthetics.

The non-flammable agent of the present invention can disinfect the combustible building interior materials by spraying or applying to a combustible material such as wood, fabric, paper, plastic, etc., and in case of a fire, it foams to form an insulating layer to insulate the poisonous cutlet. It has a suppressing effect.
