    Abstract: Methods of forming epoxy-based foams include reacting at least one sulfonyl hydrazide chemical blowing agent with at least one curing agent at a temperature between 1° C. and about 60° C. Illustratively, the curing agent is an emulsion of an adduct of a polyamine. A low density ambient cured, non-exothermic, closed cell epoxy foam may be formed for use as an insulation. This insulation may be fire retardant or fire resistant. The foam may be applied as a liquid material which then foams under ambient temperatures and pressures, or as a panel which has been pre-cast, and delivered in a slab form. Densities as low as 0.24 g/cm3 (15 lbs./ft3) can be achieved at 24° C. with compressive strengths approaching 1500 psi.

    Abstract translation: 形成环氧基泡沫的方法包括使至少一种磺酰肼化学发泡剂与至少一种固化剂在1℃至约60℃之间的温度下反应。说明性地,固化剂是一种 多胺 可以形成低密度环境固化,非放热的闭孔环氧树脂泡沫以用作绝缘体。 这种绝缘可能是阻燃或防火的。 泡沫可以作为液体材料施加,然后在环境温度和压力下被泡沫,或者作为已经预铸的面板,并以板坯形式递送。 在24℃下,压缩强度接近1500磅/平方英寸时,可达到低达0.24 g / cm3(15 lbs./ft3)的密度。
