style="text-indent:25px">色素炭黑是塑料的著色劑、防紫外線老化劑和抗靜電劑。隨著塑料行業(yè)的發(fā)展，炭黑在塑料行業(yè)的用量也越來(lái)越大，從普通的日用塑料到***的工程塑料都離不開炭黑。用量雖然不多，但它對(duì)塑料性能的影響很大，因此，對(duì)塑料用炭黑的性能要求更加嚴(yán)格，不同用途的塑料制品對(duì)炭黑性能有不同的要求，為降低塑料的成本，炭黑的用量要求盡可能地高，但是，研磨設(shè)備的性能和類型將對(duì)炭黑的分散產(chǎn)生重要的影響。不同的塑料要求不同的分散水平。在許多情況下，塑料性能的不足可以直接歸因于炭黑分散的不足，如電纜外殼和光纖等塑料產(chǎn)品，要求炭黑的分散水平能達(dá)到更高層次。對(duì)于性能要求很高的塑料，炭黑的充分分散是非常重要的。如果能提高色素炭黑的分散水平，可以使塑料的顏色、色相、粘度、光澤、穩(wěn)定性以及擠出特性等達(dá)到更好的要求。上?？ú┨靥己阡N售價(jià)格炭黑作著色時(shí)，黑度主要基于對(duì)光的吸收，對(duì)于特定濃度的炭黑，炭黑越細(xì)小，則光吸收程度越高。</p><div

由于新聞紙表面無(wú)涂布、吸收性好，新聞?dòng)湍话氵x用高、中結(jié)構(gòu)的炭黑以獲得較好的黑度。但由于新聞?dòng)湍母稍锓绞綖闈B透干燥，其耐磨擦性較差，如采用低結(jié)構(gòu)的炭黑則能提高耐磨擦性。所以國(guó)外一般將高結(jié)構(gòu)和低結(jié)構(gòu)的炭黑混合使用，以取得黑度和耐磨擦性兩者之間的平衡。 </p> <p> UV油墨用炭黑由于UV油墨的成膜機(jī)理是紫外光與UV油墨中的光引發(fā)劑作用引發(fā)的聚合反應(yīng)，而炭黑對(duì)紫外光有吸收作用，并且粒徑越小，吸收越強(qiáng)，這就造成了UV油墨的固化速度和黑度兩者之間的矛盾。另外，由于UV油墨采用的連接料對(duì)顏料的潤(rùn)濕性差，在選擇炭黑時(shí)，應(yīng)該優(yōu)先表面極性基團(tuán)豐富的氧化炭黑，以獲得良好的分散效果和儲(chǔ)存穩(wěn)定性。 </p> <p> 單張紙和輪轉(zhuǎn)膠印油墨用炭黑由于膠印印刷墨層是各種印刷方式中**薄的，炭黑在膠印油墨配方中的含量也就比較高，以期獲得滿意的黑度和遮蓋力。當(dāng)承印物為涂布紙時(shí)，印刷廠通常希望獲得較好的黑度和光澤，因此膠印油墨廠通常選用低結(jié)構(gòu)的炭黑以及經(jīng)氧化處理的低結(jié)構(gòu)炭黑作為原料。 </p><p> 二、紫外線防護(hù)性的應(yīng)用 </p> <p> 炭黑在塑料工業(yè)中用途之一是防紫外光老化，由于炭黑有較高的吸光性，因而能有效的防止塑料受陽(yáng)光照射而產(chǎn)生光氧化降解。炭黑作為紫外光穩(wěn)定劑在塑料中所起的作用有：把光能轉(zhuǎn)化為熱能；保護(hù)塑料表面而免遭一定波長(zhǎng)的射線照射；截取原子團(tuán)而產(chǎn)生防老化作用，從而阻止催化降解。紫外線對(duì)聚烯烴特別有害，試驗(yàn)證明當(dāng)一定細(xì)度的炭黑的濃度為百分之二時(shí)可以達(dá)到完美的紫外線屏蔽作用。 </p> <p> 炭黑對(duì)塑料的紫外線老化的防護(hù)作用，取決于炭黑的粒徑、結(jié)構(gòu)和表面化學(xué)性。 </p> <p> 炭黑的粒徑較小時(shí)，因表面積增大，其吸收光或遮光能力增加，故紫外線防護(hù)作用增強(qiáng)，但粒徑小于20nm，其防護(hù)作用趨于同一水平，原因是當(dāng)粒徑過(guò)小時(shí)，逆向散射減小，而繼續(xù)向前的光會(huì)威脅聚合物的穩(wěn)定性。 </p> <p> 結(jié)構(gòu)較低，即聚集體尺寸較小時(shí)，因聚集體幾何體積較小，會(huì)增強(qiáng)對(duì)聚合物的防護(hù)作用，這也是結(jié)構(gòu)較低的炭黑較黑的原因。 </p> <p> 炭黑表面含氧基團(tuán)較多，即揮發(fā)份較高時(shí)，能消除聚合物分解時(shí)產(chǎn)生的基因，因此防護(hù)作用也增強(qiáng)。由于生產(chǎn)工藝的不同，通過(guò)不同的工藝條件可得到各種性質(zhì)不同的產(chǎn)品。</p><div style="width:100%;text-align: center;"><img
