The invention discloses a flame-retardant fireproof coiled material. The flame-retardant fireproof coiled material is composed of a flame-retardant surface layer and a chopped fiber layer, the flame-retardant surface layer and the chopped fiber layer are bonded and cured by a flame-retardant coating to form the flame-retardant fireproof coiled material, and the flame-retardant coating comprises chlorinated paraffin modified polyamide. A preparation method of the polyamide comprises the following steps of: reacting chlorinated paraffin with p-hydroxybenzoic acid to prepare carboxyl-containing chlorinated paraffin, acylating the carboxyl-containing chlorinated paraffin, carrying out amidation reaction on the acylated carboxyl-containing chlorinated paraffin and tetra (4-aminophenyl) methane to prepare chlorinated paraffin modified diamine, and reacting the chlorinated paraffin modified diamine with diphenylmethane 4, 4'-dicarbonyl chloride to obtain the chlorinated paraffin modified polyamide. The preparation method has the advantages that the operation is simple, the raw material source is wide, the reaction condition is mild, the industrial production is met, and the prepared flame-retardant coiled material has good mechanical property, flame retardance and heat resistance and has a wide application prospect.
本发明公开了一种阻燃防火卷材，该阻燃防火卷材由阻燃表面层和短切纤维层组成，两者经阻燃涂料粘结固化而成，阻燃涂料包括一种氯化石蜡改性的聚酰胺，该聚酰胺的制备方法是由氯化石蜡和对羟基苯甲酸反应制备含羧基氯化石蜡，再由含羧基氯化石蜡经酰化后与四(4‑氨基苯基)甲烷通过酰胺化反应制备得到氯化石蜡改性的二元胺，然后与二苯基甲烷4,4'‑二甲酰氯反应制备得到氯化石蜡改性的聚酰胺，该制备方法操作简单、原料来源广，反应条件温和，满足工业化生产，制得的阻燃卷材具有良好的机械性能和阻燃耐热性，具有广阔的应用前景。
