uv環(huán)氧樹(shù)脂
uv環(huán)氧樹(shù)脂又稱光敏樹(shù)脂,是一種受光線照射后，能在較短的時(shí)間內(nèi)迅速發(fā)生物理和化學(xué)變化,進(jìn)而交聯(lián)固化的低聚物.是一種相對(duì)分子質(zhì)量較低的感光性樹(shù)脂,具有可進(jìn)行UV的反應(yīng)性基團(tuán),如不飽和雙鍵或環(huán)氧基等•是UV涂料的基體樹(shù)脂，它與光引發(fā)劑,活性稀釋劑以及各種助劑復(fù)配
優(yōu)點(diǎn):
(1)固化速度快,生產(chǎn)效率高;
(2)能量利用率高,節(jié)約能源;
(3)有機(jī)揮發(fā)分(VOC)少,環(huán)境友好;
(4)可涂裝各種基材,如紙張,塑料,皮革,金屬,玻璃,陶瓷等;
UV樹(shù)脂是UV涂料中比例*大的組分,是UV涂料中的基體樹(shù)脂,一般具有在光照條件下進(jìn)一步反應(yīng)或聚合的基團(tuán),如碳碳雙鍵,環(huán)氧基等.按溶劑類型的不同,UV樹(shù)脂可分為溶劑型UV樹(shù)脂和水性UV樹(shù)脂兩大類.溶劑型樹(shù)脂不含親水基團(tuán),只能溶于有機(jī)溶劑,而水性樹(shù)脂含有較多的親水基團(tuán)或親水鏈段,可在水中乳化,分散或溶解
