任何一個(gè)產(chǎn)品在使用過后沒有進(jìn)行很好的保護(hù)，時(shí)間久了肯定都會(huì)對產(chǎn)品有所影響，甚至?xí)p少產(chǎn)品的壽命或者不利于我們更好的使用。那老化了的熱熔膠會(huì)變成怎樣的呢？長期遭遇風(fēng)吹、日照、淋雨等，也會(huì)對熱熔膠的性質(zhì)造成改變，變硬后的涂膠層要是干干的，沒有一絲柔軟度，膠層逐漸會(huì)變得很脆。當(dāng)然不會(huì)像餅干那么脆，但用力掰一下還是能斷開的。到了這樣的程度，這膠層估計(jì)要經(jīng)過非常長的時(shí)間了，不然不會(huì)老化成這樣的。熱熔膠畢竟是化工用品，冒煙、有氣味都會(huì)讓人有一些顧忌，就認(rèn)為它對人體有害，是不環(huán)保的產(chǎn)品。因此，研發(fā)熱熔膠的時(shí)候，也會(huì)對其煙氣味有一個(gè)控制。雖然應(yīng)用要求高的跟某些應(yīng)用要求低的膠相比之下，煙氣味也有差別，但至少即使是粘接要求低的熱熔膠，其煙氣味也會(huì)控制在一個(gè)相對正常的范圍內(nèi)的，不會(huì)說一旦融化就冒很大的煙，那誰用都會(huì)接受不了。倘若的確冒煙嚴(yán)重，要不就是本身熱熔膠的質(zhì)量要求很低，要不就是膠鍋內(nèi)的殘留物太多，另一種可能是熱熔膠老化到特性也變了而導(dǎo)致性能很不穩(wěn)定。

style="text-indent:25px">一般說來熱熔膠和被粘體分子的極性影響著粘接強(qiáng)度，但并不意味著這些分子極性的增加就一定會(huì)提高粘接強(qiáng)度。單從極性的角度分析為了提高熱熔膠的粘接強(qiáng)度，單純改變熱熔膠和被粘體全部分子的極性，不如改變界面區(qū)表面的極性。例如聚乙烯、聚丙烯、聚四氟乙烯經(jīng)等離子表面處理后，表面上產(chǎn)生了許多極性基團(tuán)，如羥基、羰基或羧基等，從而顯著地提高了可粘接性。聚合物的分子量（或聚合度）直接影響聚合物分子間的作用力，而分子間作用力的大小決定物質(zhì)的熔點(diǎn)和沸點(diǎn)的高低，對于聚合物決定其玻璃化轉(zhuǎn)變溫度Tg和溶點(diǎn)Tm。所以聚合物無論是作為膠粘劑或者作為被粘體其分子量都影響著粘接強(qiáng)度。</p><p> 顆粒熱熔膠對溫度敏感是眾所周知的，至于在低溫下會(huì)不會(huì)脫落，這可是有眾多的說法。確實(shí)，很多人在遇到熱熔膠脫離的時(shí)候，剛好碰上氣溫低，卻往往忽略了其它因素的負(fù)面作用，從而造成不同狀況下熱熔膠脫落，但說不定與低溫?zé)o關(guān)的。當(dāng)然，要是氣溫真的很低，是會(huì)造成脫膠的，這前提是氣溫已經(jīng)超出了顆粒熱熔膠所能承受的比較低氣溫的峰值。熱熔膠顆粒和熱熔膠塊一樣，都是有一個(gè)可耐低溫的比較大值的。根據(jù)應(yīng)用條件的不同，不同廠家的不同型號的熱熔膠的性能會(huì)有差別，其中就包括耐低溫性能的表現(xiàn)。說得通俗點(diǎn)，就是氣溫在那個(gè)耐低溫的比較大值以下的，用該熱熔膠顆粒粘合的部位就存在膠層脫落的風(fēng)險(xiǎn)，而且隨著環(huán)境越惡劣，脫膠風(fēng)險(xiǎn)也會(huì)越高。在低溫環(huán)境下，也會(huì)遇上其它讓熱熔膠顆粒粘接位置變得不穩(wěn)定的因素共同作用，那便會(huì)讓情況變得很復(fù)雜，而氣溫比較低是人比較能感受到的，諸如塵灰多、膠體自身的抗氧化性能不強(qiáng)等一些不容易發(fā)現(xiàn)的因素就容易被忽略。就這樣，低溫就被認(rèn)定是造成顆粒熱熔膠脫落的原因?？梢?，顆粒熱熔膠在低溫下是未必會(huì)脫落的！

熔膠黏劑問世已有幾個(gè)世紀(jì)，然而，以合成聚合物為基料的熱熔膠黏劑直到20世紀(jì)50年代才開始在市場出現(xiàn)。熱熔膠黏劑的世界年產(chǎn)量一直處于上升趨勢，品種越來越多樣化，應(yīng)用也越來越廣。自1988年以來，熱熔膠黏劑的世界生產(chǎn)指數(shù)高于溶劑型膠黏劑和水基膠黏劑。熱熔膠黏劑以其***、適合自動(dòng)化生產(chǎn)線、操作速度快、成本低等優(yōu)勢。正逐漸取代各種傳統(tǒng)的粘接方式或膠黏劑，得到更多的重視。熱熔膠黏劑的性能通過接枝改性、共混改性和反應(yīng)固化等技術(shù)在逐步完善和提高，熱熔膠的新品種和新工藝也在不斷地發(fā)展，展現(xiàn)了美好的前景。
