In particular, it is excellent in flame retardancy and non-flammability, so it does not generate toxic gas and smoke and prevents the transition of fire in advance. It is to provide a foam and a method for producing the foam that can be foamed, molded at room temperature without the need for heating and heating when preparing the foam.

통상적으로 건축 내 외장용 단열재, 실내 인테리어, 철도차량의 내부 단열, 발전소, 원자력 등 산업분야의 보온 및 보냉, LNG & LPG 선박의 보온 및 보냉에 사용되어지고 있는 폴리 우레탄폼, 스티로폼이 난연성이나 불연성이 취약하며, 내열성도 떨어지며, 특히 화재 시 유독가스와 매연 발생으로 인하여 화재진압이 어려워 인명 피해가 속출하며, 석고보드나 글래스 울, 암면 등은 취급시 유독성으로 인체 흡입시 유해하며, 피부 자극감이 있고, 물을 흡수하여 성능이 저하되는 등 많 은 애로사항이 있었다.In general, polyurethane foam and styrofoam, which are used for insulation and interior insulation of buildings, interior insulation of railway vehicles, insulation and insulation of power plants, nuclear power, and insulation and insulation of LNG & LPG vessels, are flame retardant or non-combustible. It is vulnerable and has low heat resistance. Especially in case of fire, it is difficult to extinguish fires due to toxic gas and soot. In addition, gypsum board, glass wool and rock wool are toxic when handled and harmful to human body. In addition, there were many difficulties such as poor performance by absorbing water.

그리고 기존 난연성 발포폼 및 난연성 보드라 일컬어지는 스티로폼, 우레탄폼 등은 내발포 공정에서 추가 에너지가 소요되기도 하고, 1차 발포, 2차 발포성형 등 다공정을 통해 제조되므로 생산성이 떨어지는 문제점도 지적되었던 것이다.In addition, styrofoam and urethane foam, which are called flame retardant foams and flame retardant boards, require additional energy in the anti-foaming process. will be.

강 산성계인 H2SO4, HNO3, H3PO4, HCl 등은 투입 첨가시 폭발성과 설비의 부식성, 인체 위험성 등으로 비 안정적이므로 본 발명에서는 유기산 술폰계인 파라 톨루엔 술폰산(Para Toluene Sulfonic Acid)을 적용하였으나, 분말 상태인 파라 톨루엔 술폰산을 경화제로 주재 수지에 직접 투입시 혼련성에 문제가 있어 일부 급발열 경화, 일부 미반응 등으로 발포 불균형 상태가 되고, 발포, 경화시간의 예측불가, 폼밍상태 불균질, 피부 접촉시 화상발생 등의 문제가 있다.The strong acidic H 2 SO 4 , HNO 3 , H 3 PO 4 , HCl, etc. are non-stable due to the explosiveness and corrosion of the equipment, human risks, etc. when the addition is added in the present invention, in the present invention, organic toluene sulfonic acid (Para Toluene Sulfonic Acid) However, when para-toluene sulfonic acid in the powder state is directly added to the main resin as a curing agent, there is a problem of kneading, resulting in unbalanced foam due to some rapid heat curing, some unreacted reaction, unexpected foaming, curing time, and foaming state. There are problems such as inhomogeneity and burns upon skin contact.

이에 본 발명에서는 파라 톨루엔 술폰산을 증류수에 60~70% 희석, 완전히 용해한 약 산성계 수용액으로 주재 수지와 반응(혼합작업)시에 점도의 저하효과로 균질 혼합성이 상승하고 가사시간 조절이 가능하며, 취급시 인체 자극성이 없고, 발포폼의 셀(Cell) 구성도 균일해지는 장점을 얻을 수 있다.Thus, in the present invention, the para-toluene sulfonic acid is diluted 60-70% in distilled water and is completely dissolved in a weakly acidic aqueous solution. , When handling, there is no irritation to the human body, it is possible to obtain the advantage that the foam (Cell) configuration of the foam is also uniform.
