導(dǎo)電填料是指自身具有導(dǎo)電功能的材料，經(jīng)常使用的導(dǎo)電填料有導(dǎo)電炭黑、碳纖維、金屬填料等。導(dǎo)電橡膠的導(dǎo)電性能決定于導(dǎo)電填料填充密度、填充網(wǎng)絡(luò)結(jié)構(gòu)、基膠類(lèi)型、基膠粘度以及導(dǎo)電填料在基膠中的分散、分布情況。國(guó)內(nèi)外對(duì)導(dǎo)電填料的研究主要有碳系、金屬系、結(jié)構(gòu)型（本征型）高聚物填充劑等。 </p> <p> 碳系導(dǎo)電填料：碳系導(dǎo)電填料主要有炭黑、碳纖維和石墨。炭黑價(jià)格低，相對(duì)易加工，導(dǎo)電性能穩(wěn)定，同時(shí)對(duì)橡膠有補(bǔ)強(qiáng)作用，能提高橡膠制品的耐磨等優(yōu)異性，所以炭黑填料得到了廣發(fā)的應(yīng)用。炭黑的導(dǎo)電性能主要由炭黑的粒徑、結(jié)構(gòu)、表面狀態(tài)等因素決定，炭黑粒徑越小，比表面積越大，越容易形成導(dǎo)電通路，相同添加量的情況下越容易導(dǎo)電。碳纖維具有**度和高模量的特質(zhì)，具有密度小、力學(xué)性能好，可以在基膠中相互搭橋，使橡膠可以達(dá)到極高的導(dǎo)電性能，但是碳纖維對(duì)橡膠的耐疲勞和耐屈擾性能有不利影響。石墨由于自潤(rùn)滑作用，會(huì)造成混煉膠易碎、分層，影響橡膠工藝性能和力學(xué)性能，所以制備的導(dǎo)電橡膠綜合性能差以及導(dǎo)電性能不穩(wěn)定。因此，石墨不能單獨(dú)作為填充材料，如果和導(dǎo)電炭黑一起用于橡膠中，可以改善改善碳黑在橡膠中分散性差的問(wèn)題，減少添加量，從而改善導(dǎo)電橡膠導(dǎo)電性能。 </p><p> 導(dǎo)熱墊片具有以下優(yōu)點(diǎn)： </p> <p> 1、材料較軟，壓縮回彈性好，導(dǎo)熱絕緣性能優(yōu)異，厚度的可調(diào)范圍比較大，適宜填充不同厚度間隙，雙面具有天然粘性，可操作性和返工性強(qiáng)； </p> <p> 2、選用導(dǎo)熱墊片**主要目的是減少熱源外表與散熱器接觸表面之間發(fā)生的接觸熱阻，導(dǎo)熱墊片能夠很好的填充接觸界面之間的間隙。 </p> <p> 3、因?yàn)榭諝馐菬岬牟涣紝?dǎo)體，會(huì)嚴(yán)重影響熱量在接觸界面之間的傳遞，而在發(fā)熱源和散熱器之間使用導(dǎo)熱墊片能夠?qū)⒖諝鈹D出; </p> <p> 4、有了導(dǎo)熱墊片的填充，能夠使發(fā)熱源和散熱器之間的接觸面更好的緊密貼合，使得間隙之間形成更小的溫度梯度。 </p> <p> 5、導(dǎo)熱硅膠片的導(dǎo)熱系數(shù)具有可調(diào)控性，導(dǎo)熱性能穩(wěn)定性較好; </p> <p> 6、導(dǎo)熱硅膠片在結(jié)構(gòu)上的工藝工差補(bǔ)償，減小了散熱器和散熱結(jié)構(gòu)件的工藝工差要求; </p> <p> 7、導(dǎo)熱硅膠片具有絕緣性能 </p> <p> 8、導(dǎo)熱硅膠片具減震吸音的作用; </p> <p> 9、導(dǎo)熱硅膠片具有設(shè)備檢修時(shí)，可重復(fù)使用的方便性。金屬箔都能起到有效的電磁屏蔽效果。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
