Mineral-based expandable foams
The present invention relates to mineral-based expanded foams based on: one or more foam stabilizers; one or more pore forming agents selected from the group consisting of ammonium salts or basic salts including carbonate salts or bicarbonate salts; optionally, one or more fillers; and optionally one or more additives, characterized in that the mineral-based expansive foam is additionally based on: a polymer of one or more protective colloid-stabilized ethylenically unsaturated monomers in the form of an aqueous dispersion or a powder that can be redispersed in water; one or more pore formers selected from the group consisting of aluminum and silicon and alloys thereof and calcium carbide; and 30 wt.% to 95 wt.% of cement, relative to the dry weight of the mineral-based expansive foam, with the proviso that the proportion of the potential pore former is > = 10 wt.%, relative to the total weight of the pore former and the potential pore former.
本发明涉及矿物基膨胀泡沫，其基于：一种或多种泡沫稳定剂；一种或多种选自包括碳酸盐或碳酸氢盐的铵盐或碱性盐的组的气孔形成剂；任选的一种或多种填料；和任选的一种或多种添加剂，其特征在于，矿物基膨胀泡沫另外基于：以水分散体或可再分散在水中的粉末的形式的一种或多种保护胶体稳定的烯属不饱和单体的聚合物；一种或多种选自包括铝和硅和它们的合金和碳化钙的组的气孔形成剂；以及相对于矿物基膨胀泡沫的干重的30 wt.%至95 wt.%的水泥，条件是相对于气孔形成剂和潜在气孔形成剂的总重量，潜在气孔形成剂的比例≥10 wt.%。
