style="text-indent:25px">通用橡膠是指部分或全部代替天然橡膠使用的膠種，如丁苯橡膠、順丁橡膠、異戊橡膠等，主要用于制造輪胎和一般工業(yè)橡膠制品。通用橡膠的需求量大，是合成橡膠的主要品種。丁苯橡膠丁苯橡膠是由丁二烯和苯乙烯共聚制得的，是產(chǎn)量比較大的通用合成橡膠，有乳聚丁苯橡膠、溶聚丁苯橡膠和熱塑性橡膠（SBR）。丁腈橡膠丁腈橡膠是由丁二烯和丙烯腈經(jīng)乳液共聚而成的聚合物，丁腈橡膠以其優(yōu)異的耐油性而蓍稱，其耐油性*次于聚硫橡膠、丙烯酸酯橡膠和氟橡膠，此外丁腈橡膠還具有良好的耐磨性、耐老化性和氣密性，但耐臭氧性、電絕緣性和耐寒性都比較差，而導(dǎo)電性動(dòng)比較好。因而在橡膠工業(yè)中應(yīng)用得***。丁腈橡膠的用途，主要應(yīng)用于耐油制品，例如各種密封制品。其它還有作為PVC改性劑及與PVC并用做阻燃制品，與酚醛并用做結(jié)構(gòu)膠粘劑，做抗靜電好的橡膠制品等。</p><p style="text-indent:25px">老化因素A）氧：氧在橡膠中同橡膠分子發(fā)生游離基鏈鎖反應(yīng)，分子鏈發(fā)生斷裂或過度交聯(lián)，引起橡膠性能的改變。氧化作用是橡膠老化的重要原因之一。B）臭氧：臭氧的化學(xué)活性比氧高得多，破壞性更大，它同樣是使分子鏈發(fā)生斷裂，但臭氧對(duì)橡膠的作用情況隨橡膠變形與否而不同。當(dāng)作用于變形的橡膠（主要是不飽和橡膠）時(shí)，出現(xiàn)與應(yīng)力作用方向直的裂紋，即所謂“臭氧龜裂”；作用于變形的橡膠時(shí)，*表面生成氧化膜而不龜裂。C）熱：提高溫度可引起橡膠的熱裂解或熱交聯(lián)。但熱的基本作用還是活化作用。提高氧擴(kuò)散速度和活化氧化反應(yīng)，從而加速橡膠氧化反應(yīng)速度，這是普遍存在的一種老化現(xiàn)象－－熱氧老化。D）光：光波越短、能量越大。對(duì)橡膠起破壞作用的是能量較高的紫外線。紫外線除了能直接引起橡膠分子鏈的斷裂和交聯(lián)外，橡膠因吸收光能而產(chǎn)生游離基，引發(fā)并加速氧化鏈反應(yīng)過程。經(jīng)外線光起著加熱的作用。光作用其所長(zhǎng)另一特點(diǎn)（與熱作用不同）是它主要在橡表面進(jìn)生。含膠率高的試樣，兩面會(huì)出現(xiàn)網(wǎng)狀裂紋，即所謂“光外層裂”。醫(yī)用護(hù)理凝膠配方，找微譜！</p><div
