現在(zai)市面上主要的膠(jiao)粘劑分為水性膠(jiao)，溶劑型膠(jiao)，和熱熔膠，每一類都(dou)有其獨特(te)(te)的(de)特(te)(te)點。熱熔膠(jiao)主(zhu)要(yao)(yao)(yao)是(shi)(shi)固(gu)化時(shi)間(jian)快，粘(zhan)接強度(du)高(gao)，環(huan)(huan)保(bao)，還能起填補(bu)作(zuo)用(yong)，特(te)(te)別適(shi)合全自(zi)動生產需求,適(shi)用(yong)的(de)材料廣。水性(xing)(xing)膠(jiao)主(zhu)要(yao)(yao)(yao)是(shi)(shi)以(yi)水為(wei)溶(rong)(rong)(rong)劑(ji)(ji)的(de)膠(jiao)黏(nian)(nian)劑(ji)(ji)，主(zhu)要(yao)(yao)(yao)特(te)(te)點是(shi)(shi)無毒不(bu)燃，綠色環(huan)(huan)保(bao)，初(chu)粘(zhan)性(xing)(xing)強，但(dan)干燥速度(du)慢，粘(zhan)性(xing)(xing)不(bu)穩(wen)定(ding)，對溫(wen)度(du)比(bi)較敏(min)感，適(shi)用(yong)材料相對單一。溶(rong)(rong)(rong)劑(ji)(ji)型膠(jiao)主(zhu)要(yao)(yao)(yao)以(yi)有機溶(rong)(rong)(rong)劑(ji)(ji)為(wei)溶(rong)(rong)(rong)劑(ji)(ji)的(de)膠(jiao)黏(nian)(nian)劑(ji)(ji)，主(zhu)要(yao)(yao)(yao)特(te)(te)點是(shi)(shi)粘(zhan)接強度(du)高(gao)，耐水性(xing)(xing)好，但(dan)揮發性(xing)(xing)大，污染較大等。隨著近年社會提倡環(huan)(huan)保(bao)，人們愈加(jia)認識(shi)到(dao)溶(rong)(rong)(rong)劑(ji)(ji)型膠(jiao)帶來的(de)危(wei)害。
水性膠雖(sui)然是(shi)環保的，但與熱熔膠(jiao)相比應(ying)用領域太少(shao)，而(er)熱熔膠(jiao)(jiao)的應(ying)用非(fei)常廣泛，取代水性(xing)膠(jiao)(jiao)和溶(rong)劑型膠(jiao)(jiao)黏劑是未來發展的方向。這樣(yang)不僅能減少(shao)溶(rong)劑排(pai)放，避免造(zao)成環境污染(ran)，還可以(yi)保(bao)護(hu)生產(chan)工人的健康，所以(yi)說(shuo)熱熔膠(jiao)(jiao)即(ji)環保(bao)又(you)安(an)全！
