防火(huo)涂(tu)料的(de)防火(huo)原理大致可(ke)(ke)歸(gui)納為以(yi)下(xia)幾點：防火(huo)涂(tu)料本身具(ju)有(you)難(nan)燃(ran)(ran)性(xing)或(huo)不燃(ran)(ran)性(xing)，使(shi)被(bei)保(bao)護(hu)基(ji)(ji)(ji)(ji)材(cai)(cai)不直接(jie)與空氣(qi)接(jie)觸，延(yan)遲(chi)物(wu)體(ti)(ti)著火(huo)和減(jian)少燃(ran)(ran)燒(shao)(shao)的(de)速度(du)。防火(huo)涂(tu)料除本身具(ju)有(you)難(nan)燃(ran)(ran)性(xing)或(huo)不燃(ran)(ran)性(xing)外(wai)，它還具(ju)有(you)較(jiao)低的(de)導熱(re)(re)系數，可(ke)(ke)以(yi)延(yan)遲(chi)火(huo)焰(yan)溫(wen)度(du)向被(bei)保(bao)護(hu)基(ji)(ji)(ji)(ji)材(cai)(cai)的(de)傳遞(di)。防火(huo)涂(tu)料受(shou)熱(re)(re)分解出不燃(ran)(ran)惰性(xing)氣(qi)體(ti)(ti)，沖淡被(bei)保(bao)護(hu)物(wu)體(ti)(ti)受(shou)熱(re)(re)分解出的(de)可(ke)(ke)燃(ran)(ran)性(xing)氣(qi)體(ti)(ti)，使(shi)之不易(yi)燃(ran)(ran)燒(shao)(shao)或(huo)燃(ran)(ran)燒(shao)(shao)速度(du)減(jian)慢。含氮的(de)防火(huo)涂(tu)料受(shou)熱(re)(re)分解出NO、NH3等基(ji)(ji)(ji)(ji)團，與有(you)機游離基(ji)(ji)(ji)(ji)化合，中斷(duan)連(lian)鎖(suo)反應，降低溫(wen)度(du)。膨(peng)脹(zhang)型防火(huo)涂(tu)料受(shou)熱(re)(re)膨(peng)脹(zhang)發泡，形成(cheng)碳質泡沫(mo)隔熱(re)(re)層封閉被(bei)保(bao)護(hu)的(de)物(wu)體(ti)(ti)，延(yan)遲(chi)熱(re)(re)量與基(ji)(ji)(ji)(ji)材(cai)(cai)的(de)傳遞(di)，阻止物(wu)體(ti)(ti)著火(huo)燃(ran)(ran)燒(shao)(shao)或(huo)因(yin)溫(wen)度(du)升(sheng)高而(er)造成(cheng)的(de)強(qiang)度(du)下(xia)降。
