一、增(zeng)長亞(ya)克力面霜耐(nai)丙(bing)烯酸乳液

(1)水溶膠的利于

水溶膠并非常細(xi)小(xiao)再生(sheng)顆粒的提分(fen)子結構締合分(fen)散型體(ti),它兼備精華液(ye)系(xi)和液(ye)體(ti)系(xi)兩者之間的優點(dian),才可以能夠(gou)地提高自己耐(nai)水性聚氨(an)酯

(2) 提高皂化劑(ji)的使用

雖然說助(zhu)(zhu)溶(rong)(rong)劑(ji)對締合中膠(jiao)束(shu)的組成和(he)(he)締合后(hou)面(mian)霜的增(zeng)強性(xing)(xing)起注重(zhong)要性(xing)(xing)的效(xiao)果,但(dan)也是致使耐水(shui)溶(rong)(rong)性(xing)(xing)和(he)(he)黏(nian)著性(xing)(xing)增(zeng)漲的重(zhong)要性(xing)(xing)其原因。選擇特異(yi)的助(zhu)(zhu)溶(rong)(rong)劑(ji)或減掉助(zhu)(zhu)溶(rong)(rong)劑(ji)的容量,均可對不斷提高(gao)面(mian)霜的耐水(shui)溶(rong)(rong)性(xing)(xing)有(you)讓(rang)。

二、增長(chang)水性(xing)聚氨(an)酯精華液膠粘的(de)強度

(1)增黏光敏樹脂

增黏聚酯樹脂的(de)融入(ru),可以明顯提高(gao)壓敏膠(jiao)黏(nian)(nian)劑的(de)剝離(li)技(ji)術比(bi)強度和初粘結(jie)力。其(qi)融入(ru)的(de)方法(fa)有兩種類型。十是共混,用這種方法(fa)增(zeng)黏(nian)(nian)樹脂(zhi)(zhi)必須(xu)滿足三個基(ji)本要求:a.它(ta)的(de)分子(zi)量必須(xu)低(di)于膠(jiao)黏(nian)(nian)劑聚合物(wu)的(de)分子(zi)量;b.增(zeng)黏(nian)(nian)樹脂(zhi)(zhi)的(de)玻璃(li)化(hua)溫度必須(xu)高(gao)于聚合物(wu)的(de)玻璃(li)化(hua)溫度;c.增(zeng)黏(nian)(nian)樹脂膠與要增加的聚氨酯膠粘劑匯聚物的混溶性更好。二在開始精華液匯聚前,提前把增黏環氧樹脂充分均勻溶(rong)解于(yu)亞克力酯加(jia)聚(ju)物中,第(di)三再來水乳(ru)配位聚(ju)合,也能(neng)而來全方位的能(neng)力穩(wen)定的粘合劑。

(2)選擇不同于(yu)的締合的方法

如選擇核(he)(he)-殼(ke)締(di)合(he)。各舉締(di)合(he)物(wu)的(de)(de)核(he)(he)便(bian)(bian)(bian)用較硬(ying)的(de)(de)如苯(ben)丁二(er)烯、丙烯腈、甲基(ji)水(shui)性聚(ju)(ju)(ju)氨酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)等模(mo)(mo)型(xing),而締(di)合(he)物(wu)的(de)(de)殼(ke)便(bian)(bian)(bian)用相對較軟(ruan)的(de)(de)水(shui)性聚(ju)(ju)(ju)氨酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)烷(wan)基(ji)酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)模(mo)(mo)型(xing),這(zhe)樣子的(de)(de)結構(gou)的(de)(de)締(di)合(he)物(wu)面霜會(hui)增(zeng)加粘膠劑的(de)(de)內聚(ju)(ju)(ju)抗拉強度。選擇獨(du)特(te)的(de)(de)模(mo)(mo)型(xing),如便(bian)(bian)(bian)用適量(liang)的(de)(de)的(de)(de)水(shui)性聚(ju)(ju)(ju)氨酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)異壬基(ji)酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)與(yu)(yu)水(shui)性聚(ju)(ju)(ju)氨酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)模(mo)(mo)型(xing)進行共締(di)合(he),會(hui)進一個步驟增(zeng)加其(qi)網(wang)絡綜合(he)性。要(yao)想改進對鏈(lian)烷(wan)烴類(lei)板材的(de)(de)黏接,會(hui)便(bian)(bian)(bian)用安息(xi)香酸(suan)丁二(er)烯酸(suan)、甲基(ji)水(shui)性聚(ju)(ju)(ju)氨酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)四氫(qing)化糠(kang)基(ji)酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)、水(shui)性聚(ju)(ju)(ju)氨酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)環己酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)、2-苯(ben)氧基(ji)乙基(ji)水(shui)性聚(ju)(ju)(ju)氨酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)等模(mo)(mo)型(xing)與(yu)(yu)水(shui)性聚(ju)(ju)(ju)氨酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)烷(wan)基(ji)酯(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)共締(di)合(he),調理對非旋(xuan)光(guang)性被(bei)粘體(ti)的(de)(de)潤濕性,有(you)效果(guo)增(zeng)加黏接力。
