Fireproof and flame-retardant coiled material
The invention discloses a fireproof and flame-retardant coiled material. The fireproof and flame-retardant 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 through a flame-retardant coating, 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 esterification reaction on the acylated carboxyl-containing chlorinated paraffin and 2, 5-dihydroxyterephthalic acid to obtain modified chlorinated paraffin binary acid, acylating the modified chlorinated paraffin binary acid, reacting the acylated modified chlorinated paraffin binary acid with 1, 3-propane diamine to obtain chlorinated paraffin modified diamine, reacting the chlorinated paraffin modified diamine with 4, 4'-diacyl chloride biphenyl sulfone 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.
本发明公开了一种防火阻燃卷材，该防火阻燃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2,5‑二羟基对苯二甲酸通过酯化反应制备得到改性氯化石蜡二元酸，然后经酰化与1,3‑丙二胺反应得到氯化石蜡改性二元胺，然后与4,4'‑二酰氯联苯砜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。
