Existing flame retardants used in combustible materials such as natural wood, MDF (or plywood), veneered MDF (or plywood), PVC film MDF (or plywood), and as a single flame retardant for each wood, MDF (or plywood) veneer And MDF (or plywood) veneer urethane coating, MDF (or plywood) PVC film, etc. It is economically burdened by using individual flame retardants. There was a problem of slowing the ignition and degrading the function of generating or suppressing the amount of fumes and toxic gases.

In addition, the recent rapid spread of building materials of chemical products, causing a tremendous amount of toxic gases and smoke during fire. When building materials of chemical products are burned, there is a problem that 10 to 25 times more smoke is generated than wood is burned, and toxic gases such as hydrogen cyanide, hydrogen chloride, phosgene, carbon monoxide, and carbon dioxide are generated.

If the building material is burned during combustion, the wood acts as a fire, and the PVC sheet burns, releasing toxic gas and smoke, which increases the lives of people.

In order to improve these problems, it is necessary to manufacture a flame retardant having a function of low toxic gas, low smoke, heat resistance, and research on a flame retardant treatment method.

Accordingly, it is an object of the present invention to provide a flame retardant composition using a flame retardant composition excellent in low toxic gas, low smoke resistance and heat resistance, a method of manufacturing the same, and a flame retardant composition prepared by the method of the present invention.

The object of the present invention is to prepare a titanium magnesium ammonium phosphate-bentonite flame retardant composition by mixing the aqueous magnesium ammonium phosphate (Korean Patent Application No. 2006-28243) patent application by the present inventor to a mixture of aqueous magnesium titanium phosphate solution and bentonite This can be achieved by.

The present invention relates to a water-soluble flame retardant composition, a method for producing the same, and a method for treating flame retardant using the flame retardant composition produced by the method.

Hereinafter, the present invention will be described in more detail.

Flame retardant composition according to the present invention is a natural product that is easy to burn wood, veneer MDF or plywood (hereinafter, veneer MDF (plywood)), veneer MDF or plywood (hereinafter, veneer urethane coating MDF) Plywood)), and MDF or Plywood (hereinafter PVC film MDF) with PVC film attached, which are highly flame retardant such as phosphoric acid, nitrogen, and metal compounds, to slow the ignition and prevent the expansion of combustion. And it has the characteristics to suppress the generation of toxic gas.

The above properties are the flame retardant composition of the titanium magnesium phosphate aqueous solution 5 ~ 13% by weight, bentonite 0.1 ~ 1.0% by weight, soybean oil 0.01 ~ 0.5% by weight, baking powder 0.01 ~ 0.5% by weight, emulsifier 0.1 ~ 1.0% by weight, oleic acid 0.01 ~ It can achieve by 0.5 weight%, 1-5 weight% of bases containing dimethylamine, and 85-93 weight% of aqueous solution of magnesium ammonium phosphate.

The flame retardant composition according to the present invention is prepared by reacting inorganic magnesium and titanium metals with phosphorus and nitrogen components, so the flame retardancy is much higher than conventional flame retardants due to the synergy of magnesium hydroxide and titanium metals. Magnesium hydroxide turns into water vapor by producing water on combustion. This altered water vapor dilutes the combustible toxic gases. In addition, the surface of wood or building interior materials, which is a combustion material, is coated with diluent gas to prevent oxygen from accessing to extinguish. At the same time, the effect of reducing the production of cooling and pyrolysis products through the endothermic reaction on the solid phase surface is high. Titanium (Ti) decomposes water to produce hydrogen and titanic acid, which plays a water repellent role, and delays and prevents combustion. In addition, titanium (Ti) is a coupling agent to help the attachment of the flame retardant material to increase the flame retardant effect.

The content of the aqueous solution of titanium magnesium phosphate is not particularly limited, but is preferably 5 to 13% by weight. If the content of the magnesium magnesium phosphate aqueous solution is less than 5% by weight, the effect of titanium is inadequate, and when the content of more than 13% by weight, the content of the remaining composition is relatively reduced and the flame retardancy is inferior.

Bentonite, an additive, expands like a porous sponge during combustion, and prevents fire from burning and draws toxic gas into the porous sponge-type space and tightly confines it.

Baking powder is a synthetic expansion agent for foods, the gas generation amount is 70mL / g or more, and when the heat is received during combustion, it serves to block the combustion by foaming the surface coated with the flame retardant. Soybean oil increases the coating and water resistance of wood, veneer MDF (plywood), veneer urethane coated MDF (plywood), or PVC film MDF (plywood), and the dispersion of soybean oil for emulsifiers (e.g. sodium lauryl sulfate). When the flame retardant composition is applied to the substrate to be flame retarded, it can be better penetrated and attached. In addition, oleic acid promotes drying when the water-soluble flame retardant composition is applied to building materials.

Bentonite in the present invention is 0.1 to 1.0% by weight, soybean oil is 0.01 to 0.5% by weight, baking powder is 0.01 to 0.5% by weight, emulsifier is 0.1 to 1.0% by weight, oleic acid is preferably 0.01 to 0.5% by weight. Outside the above weight percent range, the synergistic effect of each composition is poor.

Dimethylamine dissolves unreacted debris in the manufacture of the flame retardant composition according to the invention and serves to make the flame retardant composition transparent. The content of dimethylamine is preferably 1 to 5% by weight. If the content of dimethylamine is 1 to 5% by weight because the pH of the flame retardant composition is maintained at 5-6.

The magnesium ammonium phosphate aqueous solution constituting the flame retardant coating agent composition according to the present invention serves to enhance the flame retardancy and improve the coating property. The flame retardant composition according to the present invention contains nitrogen components such as ammonium ions, and promotes thermal polycondensation of polyphosphoric acid and helps to form charcoal by generating high molecular polyphosphoric acid, which is oxidized to carbon monoxide and carbon monoxide. Suppresses the production of carbon dioxide. In addition, the synergistic effect of phosphoric acid and nitrogen becomes a low toxicity and high performance flame retardant, and has a great safety against smoke in a fire. In addition, due to the formation of a carbon film by the dehydration action it is also effective to prevent the combustion by preventing oxygen.

The content of aqueous magnesium ammonium phosphate solution is preferably 85 to 93% by weight. If the content of the aqueous magnesium ammonium phosphate solution is less than 85% by weight, the flame retardancy is lowered, and when the content of more than 93% by weight, the effect of the remaining composition is hardly expressed.
