一、水性油墨成分

水(shui)(shui)(shui)(shui)(shui)(shui)性(xing)(xing)(xing)(xing)油(you)(you)(you)(you)墨(mo)是(shi)由連(lian)(lian)結料(liao)(liao)、顏料(liao)(liao)、助劑等物質組成(cheng)的均勻漿狀物質。連(lian)(lian)結料(liao)(liao)提供油(you)(you)(you)(you)墨(mo)必要的轉移性(xing)(xing)(xing)(xing)能，顏料(liao)(liao)賦予油(you)(you)(you)(you)墨(mo)以(yi)色彩。水(shui)(shui)(shui)(shui)(shui)(shui)性(xing)(xing)(xing)(xing)油(you)(you)(you)(you)墨(mo)的連(lian)(lian)結料(liao)(liao)主要分為兩種類型(xing)(xing)：水(shui)(shui)(shui)(shui)(shui)(shui)稀(xi)釋(shi)型(xing)(xing)和(he)水(shui)(shui)(shui)(shui)(shui)(shui)分散型(xing)(xing)。前者可以(yi)使用的樹脂(zhi)類型(xing)(xing)有(you)很多種，比如(ru)順丁(ding)烯二酸樹脂(zhi)、紫膠(jiao)、馬(ma)來酸樹脂(zhi)改性(xing)(xing)(xing)(xing)蟲膠(jiao)、烏(wu)拉坦、水(shui)(shui)(shui)(shui)(shui)(shui)溶性(xing)(xing)(xing)(xing)丙烯酸樹脂(zhi)和(he)水(shui)(shui)(shui)(shui)(shui)(shui)性(xing)(xing)(xing)(xing)氨(an)基樹脂(zhi)等。水(shui)(shui)(shui)(shui)(shui)(shui)分散型(xing)(xing)的連(lian)(lian)結料(liao)(liao)是(shi)在(zai)水(shui)(shui)(shui)(shui)(shui)(shui)中(zhong)通(tong)過乳化的單體聚合所(suo)得(de)，它(ta)是(shi)兩相(xiang)體系，其中(zhong)油(you)(you)(you)(you)相(xiang)以(yi)顆(ke)粒(li)狀在(zai)水(shui)(shui)(shui)(shui)(shui)(shui)相(xiang)中(zhong)分散，雖不能夠被水(shui)(shui)(shui)(shui)(shui)(shui)溶解，但(dan)能夠被水(shui)(shui)(shui)(shui)(shui)(shui)稀(xi)釋(shi)，所(suo)以(yi)也(ye)可以(yi)認(ren)為是(shi)水(shui)(shui)(shui)(shui)(shui)(shui)包(bao)油(you)(you)(you)(you)乳液型(xing)(xing)。

二、水性油墨的優勢

由(you)于用(yong)水作溶解載體，水性(xing)油墨具有顯著(zhu)的環保安全特點：安全、無毒無害、不(bu)燃不(bu)爆，幾乎無揮發性(xing)有機氣體產(chan)生，主要表現在(zai)以下三個方面。

1、不污染環境

VOC(揮發(fa)性(xing)有(you)機氣(qi)(qi)體)被公認為(wei)當今(jin)全(quan)球大(da)氣(qi)(qi)污染(ran)的(de)主要污染(ran)源之一,溶劑型油墨會散發(fa)出大(da)量(liang)的(de)低濃度(du)VOC，由于水(shui)性(xing)油墨用(yong)水(shui)作(zuo)溶解(jie)載體．所以(yi)無論是(shi)在其(qi)生產過程中，還是(shi)被用(yong)于印(yin)刷時(shi)，幾乎不會向大(da)氣(qi)(qi)散發(fa)揮發(fa)性(xing)有(you)機氣(qi)(qi)體(VOC)，。

2、減少殘留毒物

保證食品衛生安全(quan)。水性油(you)墨(mo)完全(quan)解決了溶(rong)劑型油(you)墨(mo)的毒(du)性問題。由于不含有(you)機溶(rong)劑，使得印刷品表面殘留的有(you)毒(du)物質大(da)大(da)減(jian)少。

3、減消耗降成本

由于水性油墨(mo)固有的(de)特性——同形(xing)物含量(liang)較(jiao)高．可以在較(jiao)薄(bo)墨(mo)膜沉積。因此相(xiang)對于溶劑型(xing)油墨(mo)．它的(de)涂(tu)布量(liang)(單位印刷面積所(suo)消耗的(de)油墨(mo)量(liang))要(yao)少一些(xie)。

三、水性油墨和油性油墨的區別

水性油墨：

水(shui)性(xing)油(you)(you)墨，墨性(xing)穩定，色彩鮮艷。水(shui)性(xing)油(you)(you)墨由水(shui)性(xing)樹脂調配，可溶(rong)于水(shui)，可用(yong)(yong)水(shui)稀(xi)釋(shi)，好(hao)處是無(wu)需有機溶(rong)劑，減少溶(rong)劑揮發，能防(fang)止大氣污(wu)染，不(bu)影(ying)響人體健(jian)康，不(bu)易燃燒，屬于環保型墨水(shui)。水(shui)性(xing)油(you)(you)墨重(zhong)要的(de)是，價格便宜，印后附著力(li)好(hao)，快干，抗水(shui)性(xing)強。通常多用(yong)(yong)于食(shi)品(pin)、藥品(pin)，飲料(liao)等行業(ye)，包裝印刷品(pin)行業(ye)也(ye)應用(yong)(yong)廣泛。

油性油墨：

油(you)(you)(you)(you)(you)性(xing)(xing)(xing)油(you)(you)(you)(you)(you)墨，溶(rong)(rong)(rong)劑型(xing)油(you)(you)(you)(you)(you)墨，不易溶(rong)(rong)(rong)于水(shui)的(de)，可溶(rong)(rong)(rong)于有(you)(you)機溶(rong)(rong)(rong)劑。油(you)(you)(you)(you)(you)性(xing)(xing)(xing)油(you)(you)(you)(you)(you)墨可用(yong)有(you)(you)機溶(rong)(rong)(rong)劑稀釋，可用(yong)吸(xi)收面和非吸(xi)收表面噴(pen)印，噴(pen)印后(hou)不易褪色。油(you)(you)(you)(you)(you)性(xing)(xing)(xing)油(you)(you)(you)(you)(you)墨特點(dian)是(shi)墨水(shui)粘度大，且快干、耐(nai)水(shui)、柔(rou)和、耐(nai)光性(xing)(xing)(xing)相當好。使用(yong)時(shi)墨水(shui)更(geng)節(jie)省，有(you)(you)效(xiao)節(jie)約成本。油(you)(you)(you)(you)(you)性(xing)(xing)(xing)油(you)(you)(you)(you)(you)墨，也(ye)有(you)(you)環保型(xing)油(you)(you)(you)(you)(you)性(xing)(xing)(xing)油(you)(you)(you)(you)(you)墨，無需機溶(rong)(rong)(rong)都可進(jin)行(xing)噴(pen)碼。多用(yong)于金(jin)屬、塑料、木(mu)材、鋁(lv)箔、紙箱及(ji)建材等材質表面。
