Abstract

To solve the problem of poor water resistance and flammability of kraft paper, we proposed a simple and efficient method for preparing highly flame-retardant superhydrophobic coating for kraft paper. Ammonium polyphosphate (APP) and aluminum hydroxide (ATH) were utilized as the flame retardant layer, while Polydimethylsiloxane (PDMS) and candle soot were employed for the superhydrophobic layer. The results revealed that the limiting oxygen index (LOI) of superhydrophobic flame retardant kraft paper (SFKP) was as high as 80%, 296.0% higher than that of ordinary kraft paper (OKP). In addition, the water contact angle (WCA) of the SFKP surface reaches 154.1°, and the water sliding angle (WSA) is 3°. Meanwhile, the WCA of SFKP remains above 150° after 12 h of immersion in water. This indicates that SFKP has excellent flame retardancy and water resistance, and is expected to be utilized in harsh environments such as floods or fires.

用一种简单有效的方法在牛皮纸上制备高阻燃超疏水涂料

为解决牛皮纸耐水性差、易燃性差的问题，提出了一种简单高效的制备牛皮纸高阻燃超疏水涂料的方法。采用聚磷酸铵(APP)和氢氧化铝(ATH)作为阻燃层，聚二甲基硅氧烷(PDMS)和蜡烛烟灰作为超疏水层。结果表明:超疏水阻燃牛皮纸(SFKP)的极限氧指数(LOI)高达80%，比普通牛皮纸(OKP)高296.0%;SFKP表面的水接触角(WCA)达到154.1°，水滑动角(WSA)为3°。同时，SFKP在水中浸泡12 h后WCA保持在150°以上。这表明SFKP具有优异的阻燃性和耐水性，有望在洪水或火灾等恶劣环境中使用。
