style="text-indent:25px">近些年，**輕質(zhì)纖維增強復合材料在**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。在作為復合材料液氫貯箱的基體材料以及在超導領(lǐng)域中用作膠粘劑，浸漬料和纖維增強復合材料的基體材料等方面，我國的研究已取得一些進展。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。而作為復合材料的樹脂基體，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)生熱應力，當溫度從室溫降低至**溫(-150℃以下)時，基體內(nèi)因熱收縮而產(chǎn)生的內(nèi)應力將更加***，而一旦熱應力超過樹脂本身的強度，就會導致樹脂基體的破壞。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，當溫度降至**溫時，樹脂體系會產(chǎn)生很大的熱收縮，導致較大的熱應力，這限制了其在**溫下的應用。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。江西環(huán)氧樹脂膠粘劑哪家好</p><div

如無溶劑型膠粘劑、(有機)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)品標記：膠粘劑名稱、品種、標準號順序標記。 </p> <p> 4、按膠接強度分類 </p> <p> 結(jié)構(gòu)膠，抗剪及抗拉強度大，而且還應有較高的不均勻扯離強度，使膠接接頭在長時間內(nèi)能承受振動、疲勞及沖擊等載荷。同時還應具有較高的耐熱性和耐候性。通常鋼-鋼室溫抗剪強度>25MPa，抗拉強度≥33MPa。不均勻扯離強度>40kN/m。次受力結(jié)構(gòu)膠，能承受中等載荷。通?？辜魪姸?7—25MPa，不均勻扯離強度20—50kN/m。非結(jié)構(gòu)膠，即通用型膠粘劑。其室溫強度還比較高，但隨溫度的升高，膠接強度下降較快。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)強度。 </p> </p> <p> <br /> </p><p> 環(huán)氧樹脂除了對聚烯烴等非極性塑料粘結(jié)性不好之外，對于各種金屬材料如鋁、鋼、鐵、銅；非金屬材料如玻璃、木材、混凝土等；以及熱固性塑料如酚醛、氨基、不飽和聚酯等都有優(yōu)良的粘接性能，因此有萬能膠之稱。環(huán)氧膠粘劑是結(jié)構(gòu)膠粘劑的重要品種。 </p> <p> <br /> </p> <p> 由于環(huán)氧樹脂的絕緣性能高、結(jié)構(gòu)強度大和密封性能好等許多獨特的優(yōu)點，已在高低壓電器、電機和電子元器件的絕緣及封裝上得到廣泛應用，發(fā)展很快。主要用于： (1)電器、電機絕緣封裝件的澆注。如電磁鐵、接觸器線圈、互感器、干式變壓器等高低壓電器的整體全密封絕緣封裝件的制造。在電器工業(yè)中得到了快速發(fā)展。從常壓澆注、真空澆注已發(fā)展到自動壓力凝膠成型。江西環(huán)氧樹脂膠粘劑哪家好</p><p style="text-indent:25px">江西環(huán)氧樹脂膠粘劑哪家好</p><p> 性能優(yōu)異的環(huán)氧類膠粘劑應用領(lǐng)域*** </p> <p> 膠接（粘合、粘接、膠結(jié)、膠粘）是指同質(zhì)或異質(zhì)物體表面用膠粘劑連接在一起的技術(shù)，具有應力分膠粘劑布連續(xù)，重量輕，或密封，多數(shù)工藝溫度低等特點。膠接特別適用于不同材質(zhì)、不同厚度、超薄規(guī)格和復雜構(gòu)件的連接。膠接近代發(fā)展**快，應用行業(yè)極廣，并對高新科學技術(shù)進步和人民日常生活改善有重大影響。因此，研究、開發(fā)和生產(chǎn)各類膠粘劑十分重要。 </p> <p> <br /> </p> <p> 環(huán)氧樹脂膠（簡稱環(huán)氧膠粘劑或環(huán)氧膠）是指在一個分子結(jié)構(gòu)中，含有兩個或兩個以上的環(huán)氧基，并在適當?shù)幕瘜W試劑及合適條件下，能形成三維交聯(lián)狀固化化合物的總稱。 </p> <p> <br /> </p> 環(huán)氧樹脂膠粘劑由環(huán)氧樹脂、固化劑、增塑劑、促進劑、稀釋劑、填充劑、偶聯(lián)劑、阻燃劑、穩(wěn)定劑等組成的液態(tài)或固態(tài)膠粘劑。其中環(huán)氧樹脂、固化劑、增韌劑是不可缺少的組分，其他則根據(jù)需要決定加否。環(huán)氧膠粘劑的膠粘過程是一個復雜的物理和化學過程，包括浸潤、粘附、固化等步驟，***生成三維交聯(lián)結(jié)構(gòu)的固化物，把被粘物結(jié)合成一個整體。
