目前市場上的水性熱熔膠哪些新品在開發？
固化性(xing)(xing)(xing)(xing)(xing)(xing)水性(xing)(xing)(xing)(xing)(xing)(xing)熱熔(rong)膠(jiao)(jiao)和功(gong)能(neng)性(xing)(xing)(xing)(xing)(xing)(xing)水性(xing)(xing)(xing)(xing)(xing)(xing)熱熔(rong)膠(jiao)(jiao)是(shi)市場(chang)上(shang)的兩大類新品。前者主(zhu)要特點是(shi)，改(gai)善水性(xing)(xing)(xing)(xing)(xing)(xing)熱熔(rong)膠(jiao)(jiao)耐高溫特性(xing)(xing)(xing)(xing)(xing)(xing)，提高軟化點到120℃以(yi)(yi)上(shang)，從而擴大其使(shi)用范圍(wei)；功(gong)能(neng)性(xing)(xing)(xing)(xing)(xing)(xing)水性(xing)(xing)(xing)(xing)(xing)(xing)熱熔(rong)膠(jiao)(jiao)則是(shi)針對特定場(chang)合(he)，可以(yi)(yi)實現特定功(gong)能(neng)以(yi)(yi)滿足各方面用途需要的一類膠(jiao)(jiao)。如(ru)水溶性(xing)(xing)(xing)(xing)(xing)(xing)或分(fen)散性(xing)(xing)(xing)(xing)(xing)(xing)水性(xing)(xing)(xing)(xing)(xing)(xing)熱熔(rong)膠(jiao)(jiao)、熱熔(rong)密封膠(jiao)(jiao)、熱熔(rong)壓(ya)敏(min)膠(jiao)(jiao)等等。
目前市(shi)場上的水性(xing)熱(re)熔(rong)膠哪些新品在開(kai)發？
下面(mian)是(shi)熱熔密(mi)封膠的說明：它是(shi)一種以聚(ju)異丁烯橡膠為基(ji)料的單組份(fen)、無溶劑、不(bu)出霧、不(bu)硫化、具有(you)永 久塑性(xing)的中(zhong)空玻璃(li)首(shou)道密(mi)封劑。熱熔丁基(ji)密(mi)封膠在(zai)較寬溫度(du)范圍內保持其(qi)塑性(xing)和(he)密(mi)封性(xing)，且表面(mian)不(bu)開裂、不(bu)變(bian)硬。它對玻璃(li)、鋁(lv)合金、鍍鋅(xin)鋼、不(bu)銹鋼等材料有(you)良(liang)好的粘合性(xing)。由于其(qi)極低(di)的水汽透過率，它可(ke)以與彈性(xing)密(mi)封劑一起構成一個優異的抗濕氣系統。特點：密(mi)封效果好、質量容易保證；無需固化期，節省(sheng)占地面(mian)積；屬(shu)環保產品，使用無浪費(fei)，環境清(qing)潔；節省(sheng)時間(jian)，原材料、工作人員、降低(di)生(sheng)產成本(ben)。
除較通(tong)用(yong)的(de)EVA、TPR類水性(xing)(xing)熱(re)(re)(re)熔(rong)(rong)膠(jiao)外，企(qi)業(ye)還應(ying)著力研究開發(fa)當(dang)前西(xi)方已大(da)量應(ying)用(yong)且應(ying)用(yong)潛力巨大(da)的(de)一些高(gao)新水性(xing)(xing)熱(re)(re)(re)熔(rong)(rong)膠(jiao)產(chan)品，具體包括：反應(ying)型水性(xing)(xing)熱(re)(re)(re)熔(rong)(rong)膠(jiao)、水分散型水性(xing)(xing)熱(re)(re)(re)熔(rong)(rong)膠(jiao)、高(gao)檔(dang)PA熱(re)(re)(re)熔(rong)(rong)襯膠(jiao)粒以及高(gao)強度熱(re)(re)(re)熔(rong)(rong)壓敏膠(jiao)等。同(tong)時(shi)國內有關原(yuan)(yuan)(yuan)材(cai)料(liao)生產(chan)廠(chang)家(jia)也應(ying)認識到水性(xing)(xing)熱(re)(re)(re)熔(rong)(rong)膠(jiao)行(xing)業(ye)的(de)發(fa)展潛力，加快提高(gao)原(yuan)(yuan)(yuan)材(cai)料(liao)的(de)國產(chan)化(hua)率，減少因大(da)量進(jin)口原(yuan)(yuan)(yuan)材(cai)料(liao)而造成(cheng)的(de)外匯流失。
