style="text-indent:25px">近些年，**輕質(zhì)纖維增強(qiáng)復(fù)合材料在**溫環(huán)境中逐漸使用，對環(huán)氧樹脂的**溫性能研究也日益加強(qiáng)。在作為復(fù)合材料液氫貯箱的基體材料以及在超導(dǎo)領(lǐng)域中用作膠粘劑，浸漬料和纖維增強(qiáng)復(fù)合材料的基體材料等方面，我國的研究已取得一些進(jìn)展。純環(huán)氧樹脂具有很高的交聯(lián)密度，即使在常溫下也存在著質(zhì)脆、韌性低、抗沖擊性差等缺點(diǎn)。而作為復(fù)合材料的樹脂基體，一般都需要在很高的溫度下固化。在固化后冷卻過程中，由于熱收縮樹脂基體內(nèi)部會產(chǎn)生熱應(yīng)力，當(dāng)溫度從室溫降低至**溫(-150℃以下)時，基體內(nèi)因熱收縮而產(chǎn)生的內(nèi)應(yīng)力將更加***，而一旦熱應(yīng)力超過樹脂本身的強(qiáng)度，就會導(dǎo)致樹脂基體的破壞。因此，提高韌性對環(huán)氧樹脂在**溫下的使用至關(guān)重要。目前提高環(huán)氧樹脂**溫韌性的方法主要是使用柔性的脂肪族樹脂和液體橡膠以及柔性固化劑來增韌環(huán)氧樹脂。由于此類材料玻璃化轉(zhuǎn)變溫度較低，常溫下具有較大的自由體積，當(dāng)溫度降至**溫時，樹脂體系會產(chǎn)生很大的熱收縮，導(dǎo)致較大的熱應(yīng)力，這限制了其在**溫下的應(yīng)用。常溫下高性能熱塑性塑料與環(huán)氧樹脂的共混改性，可使共混體系同時兼具有兩者的優(yōu)越性能，即在保持熱固性樹脂高模量的同時，又兼具熱塑性塑料的高韌性。湖南環(huán)氧樹脂膠粘劑價格</p><div

style="text-indent:25px">環(huán)氧類膠粘劑粘接力大，粘接強(qiáng)度高；收縮率小，尺寸穩(wěn)定，環(huán)氧樹脂膠在固化時幾乎不放出低分子產(chǎn)物．線膨脹系數(shù)受溫度影響小，因此，粘接件的尺寸穩(wěn)定性好；環(huán)氧樹脂膠的固化產(chǎn)物具有優(yōu)異的電絕緣性能，體積電阻率為1013～1016Ω.cm，介電強(qiáng)度為30～50KV.Mm-1環(huán)氧樹脂分子中含有醚鍵，且分子鏈間排列緊密，交聯(lián)密度又大，故有良好的耐溶劑、耐油、耐酸、耐堿、耐水等性能，特別是耐堿性強(qiáng)；環(huán)氧樹脂與很多的橡膠(彈性體)及熱塑性樹脂相溶性好，甚至發(fā)生化學(xué)反應(yīng)；與填料分散性好，可在很大范圍內(nèi)改變環(huán)氧樹脂膠的性能；工藝性好，使用方便，毒性較低，危害性??；樹脂中含有很多的苯環(huán)和雜環(huán)，分子鏈柔性小，加之固化后的交聯(lián)結(jié)構(gòu)不宜變形，未增韌的環(huán)氧樹脂膠韌性不好，脆性較大，剝離強(qiáng)度很低，不耐沖擊振動。</p><p> 環(huán)氧膠粘劑的分類： </p> <p> 1、按形態(tài)分類 </p> <p> 如無溶劑型膠粘劑、(有機(jī))溶劑型膠粘劑、水性膠粘劑(又可分為水乳型和水溶型兩種)、膏狀膠粘劑、薄膜狀膠粘劑(環(huán)氧膠膜)等。 </p> <p> 2、按固化條件分類 </p> <p> 冷固化膠(不加熱固化膠)。又分為：低溫固化膠，固化溫度<15℃;室溫固化膠，固化溫度15—40℃。 </p> <p> 熱固化膠。又可分為：中溫固化膠，固化溫度約80—120℃;高溫固化膠，固化溫度>150℃。 </p> <p> 其他方式固化膠，如光固化膠、潮濕面及水中固化膠、潛伏性固化膠等。 </p> <p> 3、按固化速度分類 </p> <p> 快固型(K)和普固型(P) </p> <p> 產(chǎn)品標(biāo)記：膠粘劑名稱、品種、標(biāo)準(zhǔn)號順序標(biāo)記。 </p> <p> 4、按膠接強(qiáng)度分類 </p> <p> 結(jié)構(gòu)膠，抗剪及抗拉強(qiáng)度大，而且還應(yīng)有較高的不均勻扯離強(qiáng)度，使膠接接頭在長時間內(nèi)能承受振動、疲勞及沖擊等載荷。同時還應(yīng)具有較高的耐熱性和耐候性。通常鋼-鋼室溫抗剪強(qiáng)度>25MPa，抗拉強(qiáng)度≥33MPa。不均勻扯離強(qiáng)度>40kN/m。次受力結(jié)構(gòu)膠，能承受中等載荷。通?？辜魪?qiáng)度17—25MPa，不均勻扯離強(qiáng)度20—50kN/m。非結(jié)構(gòu)膠，即通用型膠粘劑。其室溫強(qiáng)度還比較高，但隨溫度的升高，膠接強(qiáng)度下降較快。只能用于受力不大的部位。 </p><p> <p> 環(huán)氧樹脂膠粘劑原理分析： </p> <p> 配方中，環(huán)氧樹脂和聚氯乙烯樹脂為主要膠粘成分；鄰苯二甲酸二辛脂為增塑劑；石英粉和白炭黑為填充改性劑；三氟化硼甘油，三氟化硼苯胺，二縮三乙二醇胺為固化劑；磷酸為酸化劑，并起固化促進(jìn)作用及增加對金屬的粘合力。 </p> <p> 雙組分室溫固化的環(huán)氧膠粘劑。被粘合的表面上涂以本品后，施加一定壓力。即可讓其在室溫下固化。出固化條件為：16.5攝氏度時14-16秒，25攝氏度時7-9秒，30攝氏度時4-6秒。主要用于各種金屬與金屬，金屬與非金屬，以及各種硬塑料制品的粘合，具有很高的粘結(jié)強(qiáng)度。 </p> </p> <p> <br /> 湖北環(huán)氧樹脂膠粘劑生產(chǎn)單位</p><p style="text-indent:25px">湖南環(huán)氧樹脂膠粘劑價格</p><p> 環(huán)氧類膠粘劑主要由環(huán)氧樹脂和固化劑兩大部分組成。為改善某些性能，滿足不同用途還可以加入增韌劑、稀釋劑、促進(jìn)劑、偶聯(lián)劑等輔助材料。由于環(huán)氧膠粘劑的粘接強(qiáng)度高、通用性強(qiáng)，曾有“萬能膠”、“大力膠”之稱，在航空、航天、汽車、機(jī)械、建筑、化工、輕工、電子、電器以及日常生活等領(lǐng)域得到***的應(yīng)用。 </p> <p> <br /> </p> <p> <br /> </p> <p> 一般環(huán)氧樹脂結(jié)構(gòu)中含有羥基、醚鍵使它有高的粘接性，由于這些極性基團(tuán)，因此能使相鄰界面產(chǎn)生電磁力，在固化過程少，伴隨和固化劑的化學(xué)作用，還能進(jìn)一步生成經(jīng)基和醚鍵，不僅有較高的內(nèi)聚力，而且產(chǎn)生很強(qiáng)的粘附力，所以環(huán)氧膠粘劑對許多種材料如金屬、塑料、玻璃、木材、纖維等都具有很強(qiáng)的粘接強(qiáng)度，俗稱“萬能膠”。
