补充资料：防冻剂
分子式：
CAS号：
性质：又称抗冻剂。能在低温下防止物料中水分结冰的物质。分冰点降低型和表面活性剂型两类。降低冰点的有低碳醇类、二元醇及酰胺类等。表面活性剂型能使物料在表面形成疏水性吸收膜，如酸性磷酸酯胺盐、烷基胺、脂肪酸酰胺、有机酸酯、烷基丁二酰亚胺等。如在混凝土中为掺入冬季施工混凝土中能使混凝土在负温下硬化，并在规定时间内达到足够防冻强度。可制成粉状或液体。用以防止混凝土在冬季负温下施工产生的冻涨破坏。保证负温下混凝土的正常施工。其主要成分为亚硝酸钠、碳酸盐、氯化钙、亚硝酸钙、尿素、乙二醇等。它们可以降低混凝土拌和物中的冰点。也可以与减水剂、引气剂等复合防冻，效果更好。
