PHENOLIC FOAM INSULATION AND ITS MANUFACTURING METHOD
The present invention relates to a phenolic foam heat insulation material obtained by foaming and curing a foamable phenolic resin composition including a phenolic resin, a foaming agent, an acid catalyst and an inorganic neutralizer, wherein the inorganic neutralizer is at least one selected from the group consisting of aluminum hydroxide, zinc oxide, calcium carbonate and magnesium carbonate, and is coated with a binder. The phenolic foam heat insulation material and the method for manufacturing the same can prevent cell cracking and degradation of heat insulation performance caused by the use of the inorganic neutralizer, and can inhibit generation of metal corrosion upon the contact with a metallic material. In addition, the phenolic foam heat insulation material can be used safely as a heat insulation material by removing the unreacted formaldehyde therein.
개시된 내용은 페놀 수지, 발포제, 산 촉매 및 무기 중성화제를 포함하는 발포성 페놀 수지 조성물을 발포, 경화시켜 이루어지는 페놀폼 단열재로서, 상기 무기 중성화제는 수산화알루미늄, 산화아연, 탄산칼슘 및 탄산마그네슘으로 이루어지는 군에서 선택되는 적어도 하나이며, 상기 무기 중성화제가 결합제로 코팅된 것을 특징으로 하는 페놀폼 단열재에 대해 기술하고 있다. 상기와 같은 페놀폼 단열재 및 이의 제조방법은 무기 중성화제 사용에 의한 셀 균열 및 단열 성능저하를 예방하고, 금속 재료와 접촉 시 금속의 부식 발생을 억제할 수 있다. 또한 페놀폼 단열재 내부 미반응 포름알데히드를 제거하여 단열재로서 안전하게 사용할 수 있다.
