1、銀粉導電膠
銀享有優秀(xiu)的(de)導電(dian)(dian)耐(nai)腐(fu)蝕性(xing)和傳熱(re)性(xing)耐(nai)腐(fu)蝕性(xing),水的(de)電(dian)(dian)導率電(dian)(dian)動(dong)車(che)續(xu)航6.3×107 S/m,熱(re)導率達429 W/(m?K)。銀在氣(qi)體中不會被(bei)脫(tuo)色,且脫(tuo)色后的(de)物質(zhi)仍具導電(dian)(dian)性(xing);時候(hou),銀收(shou)費(fei)底于金或鉑(bo),對此銀是(shi)里常用、最好的(de)導電(dian)(dian)懸浮(fu)填(tian)料之(zhi)六。
中(zhong)國大(da)陸以銀(yin)(yin)粉(fen)為(wei)導(dao)電(dian)(dian)懸浮(fu)人工濕(shi)地填(tian)料的(de)(de)導(dao)電(dian)(dian)膠總類繁雜。如王萍(ping)等[11]最新發明的(de)(de)單組份固(gu)化劑不飽(bao)和樹脂膠-銀(yin)(yin)導(dao)電(dian)(dian)膠,以固(gu)化劑不飽(bao)和樹脂膠為(wei)基(ji)體,納米級(ji)顆粒狀銀(yin)(yin)粉(fen)(0.5 μm)為(wei)導(dao)電(dian)(dian)懸浮(fu)人工濕(shi)地填(tian)料所制(zhi)取(qu)的(de)(de)樣(yang)品管理中(zhong),銀(yin)(yin)的(de)(de)占比高出(chu) 60%時,導(dao)電(dian)(dian)膠近乎不導(dao)電(dian)(dian),而當(dang)銀(yin)(yin)占比過于(yu) 80%時,導(dao)電(dian)(dian)膠的(de)(de)拉申彈簧(huang)密(mi)度短時間越(yue)來(lai)越(yue)低。虞(yu)鑫海等[12]制(zhi)取(qu)的(de)(de)JP-6新式導(dao)電(dian)(dian)膠具備(bei)著特別達標率(lv)(lv)的(de)(de)黏結機(ji)械(xie)特性與(yu)導(dao)電(dian)(dian)機(ji)械(xie)特性,其拉申彈簧(huang)削切密(mi)度電(dian)(dian)動車續(xu)航21 MPa,量大(da)小電(dian)(dian)容功(gong)率(lv)(lv)率(lv)(lv)有(you)3.26×10-4 Ω?cm。該導(dao)電(dian)(dian)膠能夠在85℃常溫包括濕(shi)潤的(de)(de)區域中(zhong)長(chang)期選(xuan)用,經240 h濕(shi)熱老化測試檢驗后,其拉申彈簧(huang)削切密(mi)度仍電(dian)(dian)動車續(xu)航到(dao)17.8 MPa,量大(da)小電(dian)(dian)容功(gong)率(lv)(lv)率(lv)(lv)達2.66×10-4 Ω?cm。
總的(de)一(yi)般而言(yan),內(nei)地的(de)導(dao)電膠(jiao)(jiao)在多問題(ti)面(mian)能力(li)(li)有(you)更大不斷進步,但在抗老化測試(shi)能力(li)(li)、膠(jiao)(jiao)黏能力(li)(li)、穩定的(de)性等(deng)問題(ti)仍(reng)較歐(ou)洲有(you)相(xiang)比(bi)。表(biao)2[13]標出了常(chang)用的(de)銀粉導(dao)電膠(jiao)(jiao)的(de)能力(li)(li)。
2 銅粉導電膠
銀(yin)固然含有(you)優秀企業(ye)的導(dao)電(dian)、導(dao)熱性穩定性及清除自(zi)由(you)基的水平,但是因(yin)為(wei)銀(yin)粉收(shou)費較高,且其導(dao)電(dian)膠中會(hui)存在(zai)電(dian)商轉化問題,銀(yin)粉導(dao)電(dian)膠的應用軟(ruan)件廣受了控制。這樣有(you)所作為(wei)銀(yin)粉導(dao)電(dian)膠的代替品類(lei)產品,銅(tong)粉導(dao)電(dian)膠的分析廣受了解。
趙勇[14]用(yong)改(gai)造(zao)環氧(yang)防銹漆樹脂(zhi)膠、抗氧(yang)劑(ji)、800目銅粉(fen)與改(gai)良胺固(gu)有(you)劑(ji)、重(zhong)置(zhi)劑(ji)確定的(de)(de)質(zhi)量(liang)(liang)(liang)比6∶1.8的(de)(de)配置(zhi)比例混合式(shi)制(zhi)取質(zhi)量(liang)(liang)(liang)中考(kao)分(fen)數功率(lv)(lv)電(dian)阻(zu)值功率(lv)(lv)比率(lv)(lv)有(you)1.2×10-3 Ω?cm、剪截(jie)強(qiang)度(du)8.8 MPa、在(zai)25℃狀態下8 h既可(ke)以(yi)固(gu)有(you)的(de)(de)室(shi)內溫度(du)導電(dian)膠,適宜中用(yong)不禁止蒸汽加熱的(de)(de)網絡元電(dian)子電(dian)子原件、實驗室(shi)設(she)備的(de)(de)導電(dian)聯接。此時框架上(shang),黃(huang)麗娟[15]制(zhi)取的(de)(de)銅粉(fen)充實量(liang)(liang)(liang)(的(de)(de)質(zhi)量(liang)(liang)(liang)中考(kao)分(fen)數)為68%的(de)(de)導電(dian)膠,其質(zhi)量(liang)(liang)(liang)中考(kao)分(fen)數功率(lv)(lv)電(dian)阻(zu)值功率(lv)(lv)率(lv)(lv) 1.2×10-3 Ω?cm,拉伸彈簧剪截(jie)強(qiang)度(du) 10.8 MPa。Marshall[16]備制(zhi)的(de)(de)銅粉(fen)導電(dian)膠功率(lv)(lv)電(dian)阻(zu)值功率(lv)(lv)比率(lv)(lv)有(you)(0.5~1)×10-3 Ω?cm。
