황산알루미늄(aluminum sulfate)은 18수화물로서 무색결정이며, 비중은 1.69 융점 86.5℃ 물에 녹으며, 알콜에는 녹지 않는다. 수소이온농도(PH)는 3 으로서 수돗물 정수, 소화기, 방수포로 주로 사용한다. 염화알루미늄(aluminum chloride)의 수소이온농도(PH)는 3으로서 목재등의 방부제로 사용하며, 난연성이 뛰어나며, 물에 녹는다. 염화마그네슘(magnesium chloride)은 목재방부제, 소화제, 식품첨가물로 사용하며, 비중 1.569, 100℃에서 2H2 O를 잃고 가열하면 무수물이 안 되고, 가수분해 되며, 약 600℃에서 마그네시아가 된다. 인산암모늄(ammonium phosphate)으로는 1인산암모늄(ammonium phosphate monobasic)과 2인산암모늄(ammonium phosphate dibasic) 이 있다, 본 발명에서는 1인산암모늄을 사용하였으며, 무색무취, 공기중에 안정하고, 물에 녹으며, 190℃가열하면 물과 암모니아를 방출하여 소화제, 방화도료의 배합제, 난연제등, 수소이온농도(PH)조절 목적으로 식품첨가물에 사용하고 있으며, 수소이온농도(PH)는 3.0-4.4이다. 본 발명에서 중요성분으로서 규산소다(sodium silicate)는 수용성 규산염으로서, 불휘발분이 45％이상의 것을 사용하였고, 불연성 원료로 스티로폼에 피막을 형성하여 화재발생시에 스티로폼의 형상 변화 방지 목적으로 사용하였다. 카제인(casein)은 단백질로서 물에는 녹지 않아 규산소다(sodium silicate)에 첨가하여 가수분해 반응에 의하여 물과 함께 용해 불연제로 사용하였다. 이와 같은 조성물이 성형된 스티로폼(발포 폴리스티렌 보온재)에 용이하게 침투되지 않아 계면활성제로서 천연고분자 물질과 동, 식물성 계면활성제를 합성한 기포제(polypeptide 계면활성제화합물)를 첨가하여 본 발명의 조성물이 스티로폼 내부에 용이하게 침투되도록 하였다.Aluminum sulfate is a 18-hydrate, colorless crystal, specific gravity 1.69 melting point 86.5 ℃ soluble in water, insoluble in alcohol. Hydrogen ion concentration (PH) is 3, and it is mainly used for tap water purification, fire extinguisher, and tarpaulin. Hydrogen concentration (PH) of aluminum chloride is 3, and it is used as a preservative of wood, etc. It is excellent in flame retardancy and is soluble in water. Magnesium chloride is used as a wood preservative, fire extinguishing agent and food additive. When it loses 2H 2 O at specific gravity of 1.569 and 100 ℃, it is not anhydrous, hydrolyzed and becomes magnesia at about 600 ℃. Ammonium phosphate includes ammonium phosphate monobasic and ammonium phosphate dibasic.

When heated at 190 ℃, it releases water and ammonia and is used in food additives to control hydrogen ion concentration (PH), such as fire extinguishing agent, fire retardant paint compound, flame retardant, etc., and hydrogen ion concentration (PH) is 3.0-4.4. As an important component in the present invention, sodium silicate was used as a water-soluble silicate, having a nonvolatile content of 45% or more, and forming a film on styrofoam as a nonflammable raw material to prevent the shape change of styrofoam in case of fire. Casein is a protein, insoluble in water, added to sodium silicate, and used as a dissolution inflammable with water by hydrolysis. Since such a composition does not easily penetrate into the molded styrofoam (foamed polystyrene insulation), the composition of the present invention is added to the inside of the styrofoam by adding a natural polymer material, a polypeptide surfactant compound synthesizing a vegetable surfactant as a surfactant. It was to be easily penetrated into.
