隨著硅膠行業(yè)技術(shù)的不斷創(chuàng)新進(jìn)步，硅橡膠在生活中的應(yīng)用也越來越廣，但是有時(shí)候在應(yīng)用中會(huì)碰到一些問題，如硅橡膠如何才能夠跟金屬粘接，下面我們就來看一下實(shí)現(xiàn)硅橡膠與金屬粘接的4步流程：一、金屬表面處理要實(shí)現(xiàn)粘合，首先要對(duì)金屬表面進(jìn)行處理，常用的方法是：化學(xué)、機(jī)械和溶劑三種，一般硅膠制品廠是根據(jù)實(shí)際來選用方法，機(jī)械法處理常采用噴砂，南京質(zhì)量硅膠與金屬粘合件銷售廠家、用砂布或砂輪打磨等方法，特別是噴砂法、成本低、速度快、效果好，獲得廣泛應(yīng)用。化學(xué)方法處理也較常用，尤其是鋁及其合金的陽極化處理，鋼的鍍銅處理，需用化學(xué)法。經(jīng)處理后的金屬表面，南京質(zhì)量硅膠與金屬粘合件銷售廠家，處理后的表面要及時(shí)涂上膠粘劑、貼上硅橡膠或浸入惰性溶劑中。二、金屬接頭的設(shè)計(jì)要實(shí)現(xiàn)硅橡膠與金屬的黏接，南京質(zhì)量硅膠與金屬粘合件銷售廠家，其次要從粘合的接頭開始，下面先了解接頭的設(shè)計(jì)原理1）盡量增大粘合面積，提高粘合接頭的承載力；2）粘合接頭的受力方式應(yīng)是剪切力或拉伸力，防止剝離力；3）在受力方向的粘合長度不宜太長，應(yīng)盡量增加粘合寬度；4）疊層粘合的受力方向應(yīng)避免層間分離；5）斜角粘合優(yōu)于直角粘合；6）橫向受力的接頭應(yīng)采用模面粘合。根據(jù)以上原則及橡膠制品的特點(diǎn)，一般采用在金屬件鉆孔、車螺紋溝槽等方法，以提高接頭粘合強(qiáng)度。硅膠包膠廠家定制，醫(yī)療器械硅膠配件包膠件。南京質(zhì)量硅膠與金屬粘合件銷售廠家</p><div

順丁橡膠是由丁二烯聚合而成的順式結(jié)構(gòu)橡膠。優(yōu)點(diǎn)：彈性與耐磨性優(yōu)良，耐老化性好，耐低溫性優(yōu)異，在動(dòng)態(tài)負(fù)荷下發(fā)熱量小，易于金屬粘合。缺點(diǎn)：強(qiáng)度較低，抗撕裂性差，加工性能與自粘性差。使用溫度范圍：約-60℃~+100℃。用途：順丁橡膠較廣地用于輪胎制造，所制出的輪胎胎面，在苛刻的行駛條件下，如高速、路面差、氣溫很低時(shí)，可以明顯地改善耐磨耗性能，提高輪胎的使用壽命。順丁橡膠還可以用來制造其他耐磨制品，如膠鞋、膠管、膠帶、膠輥等，以及各種耐寒性要求較髙的制品。異戊橡膠(IR)異戊橡膠是由異戊二烯單體聚合而成的一種順式結(jié)構(gòu)橡膠。異戊橡膠的化學(xué)組成、立體結(jié)構(gòu)與天然橡膠相似，性能也非常接近天然橡膠，故有合成天然橡膠之稱。異戊橡膠具有天然橡膠的大部分優(yōu)點(diǎn)，耐老化由于天然橡膠，彈性和強(qiáng)力比天然橡膠稍低，加工性能差，成本較高。優(yōu)點(diǎn)：彈性好、耐寒性（?；瘻囟?68℃）及很高的拉伸強(qiáng)度。缺點(diǎn)：加工性能如混煉、壓延等比天然橡膠稍差。南京質(zhì)量硅膠與金屬粘合件銷售廠家滾筒包膠，蘇州思飛定制耐磨耐油抗腐蝕高回彈。</p><div

硫化劑：一般硫磺含量較高的橡膠容易粘接不同硫化體系的彈性體粘接：常規(guī)硫化體系優(yōu)于半硫化體系；半硫化體系優(yōu)于有效硫化體系（低硫高促硫化體系）；硫黃硫化優(yōu)于其他硫化體系，如過氧化物硫化體系、雙酚A硫化體系、胺硫化體系等。（默默插一句：考慮好硫化體系哦!）促進(jìn)劑：MBT（2-硫醇基苯并噻唑）：易粘接ZDMC（二甲基二硫代氨基甲酸鋅）、TMTD（二硫化四甲基秋蘭姆）：難粘接，尤其是在有效硫化體系、半有效硫化體系中時(shí)。防焦劑：量大難粘，＜填料：填料的類型與用量是關(guān)鍵因子。炭黑一般在40-80份較易粘接；炭黑主填料的橡膠含3-5份白炭黑較易粘接。彈性體不用炭黑，而使用粘土、白炭黑，其趨勢(shì)與炭黑相同。 </p><p> 三元乙丙橡膠三EPDMEPDM是另一種優(yōu)良的橡膠減振材料，廣泛應(yīng)用于各種減振產(chǎn)品中。它具有較好的耐氧化好的耐氧化、抗臭氧和抗侵蝕的能力抗臭氧和抗侵蝕的能力。EPDM對(duì)各種惡劣氣候的適應(yīng)能力較強(qiáng)對(duì)各種惡劣氣候的適應(yīng)能力較強(qiáng)，其物理性能穩(wěn)定，且成本較低。EPDM的另一個(gè)優(yōu)勢(shì)是易于硫化，因此與金屬黏合時(shí)附著性好屬黏合時(shí)附著性好。EPDM的缺點(diǎn)是耐高溫性能不如的缺點(diǎn)是耐高溫性能不如VQM，可承受的比較高工作溫度為150℃。氯丁橡膠CRCR雖然屬于不飽和橡膠，但它的性能介于飽和和不飽和橡膠的性能之間，由于極性高且為結(jié)晶橡膠，所以物理機(jī)械性能較好，又具備極性橡膠的特點(diǎn)。一般性能：1、力學(xué)性能較高：自補(bǔ)強(qiáng)＋極性橡膠2、良好的耐油性能：耐油橡膠，但耐油性不如NBR。3、良好的耐疲勞性能：用于同步帶、齒形帶4、較差的低溫性能：CR的比較低使用溫度為－30℃，在油中的耐低溫性能優(yōu)于ACM、CPE、高ACN含量的NBR和FPM，因?yàn)樗诘蜏叵陆Y(jié)晶。5、良好的耐老化性能：CR的耐老化和耐臭氧性能優(yōu)于NR、SBR、BR、NBR，僅次于EPM和IIR，這與Cl的吸電性有關(guān)。6、電絕緣性能差7、氣密性比一般合成橡膠高8、良好的粘合性能：具有較好的自粘性和互粘性9、耐燃性能好：CR的氧指數(shù)為38~41。生產(chǎn)定制橡膠包膠輪橡膠包膠件定制橡膠包膠廠家。</p><div

異氰酸酯膠粘劑主要用于NR、CR、NBR等橡膠與鋼、不銹鋼、鋁和鋅等多種金屬材料之間的粘接。粘合強(qiáng)度高，操作工藝簡(jiǎn)單，耐油、耐溶劑、耐老化、耐酸、耐腐蝕，但耐熱性不如鍍黃銅法。常用的多異氰酸酯膠粘劑：①列克鈉（JQ-1膠粘劑）：三苯基甲烷三異氰酸酯，易溶于二氯甲烷、二氯乙烷或氯苯中作膠粘劑。一般為三苯基甲烷三異氰酸酯20%的二氯乙烷溶液，毒性較二異氰酸酯小，耐油，耐疲勞。使用時(shí)注意：a.涂層要薄，＜10μm，比較大不超過30μm。b.使用前用純二氯乙烷按1:1或1:3的比例對(duì)膠粘劑進(jìn)行稀釋。c.操作環(huán)境濕度＜60%~70%。d.一般涂刷1~2遍，涂刷后需干燥，再涂一層保護(hù)性膠粘劑或貼一薄層（）硬度為60度左右的膠片作過渡層，不宜用直接蒸汽硫化。e.列克鈉易聚結(jié)，宜采用注壓工藝和快速硫化方法；若采用模壓生產(chǎn)時(shí)，壓力必須在.f.應(yīng)盡量縮短涂膠粘劑后到硫化之前的停放時(shí)間。g.用列克鈉粘接NR或SBR與金屬時(shí)，用CR-酚醛樹脂作中間層，可提高粘接強(qiáng)度。h.異氰酸酯液中摻用少量氯化NR橡膠，可提高粘接強(qiáng)度。例：大型橡膠護(hù)舷的粘合鋼板先經(jīng)噴砂，脫脂處理后，涂刷列克鈉膠粘劑，干燥后涂刷保護(hù)膠液，加貼一層高硬度（邵A82~85度）膠料，再貼上NR。硅膠包膠件,硅膠包PC塑料件生產(chǎn)廠家_思飛硅膠。南京質(zhì)量硅膠與金屬粘合件銷售廠家</p><p

影響粘合效果的因素：①內(nèi)因：被黏面的性質(zhì)。②外因：空氣的濕度、溫度；工藝因素：溫度壓力時(shí)間。接2題：來降低表面能趨于穩(wěn)定，所以固體表面會(huì)產(chǎn)生吸附作用。2.固體表面吸附如何產(chǎn)生？答：固體表面層分子受周圍的力場(chǎng)平衡，只能從周圍介質(zhì)中捕獲氣相，吸附性對(duì)粘合有何影響？答：①有利于粘合:提供吸附力②不利于：表面易污染，吸附灰塵、氣體。濕潤對(duì)粘合的影響？答：兩表面互相濕潤是粘合的必要條件，但不是只有條件。液體在固體表面濕潤有利于粘合；液體在固體表面不濕潤，不利于粘合。3.被粘材料表面多孔性對(duì)粘合有什么影響？答：①增大表面積和表面能，提高吸附性②窩藏空氣，減少接觸面積，粘合性下降。4.膠料的流動(dòng)性對(duì)骨架材料粘合的影響？答：流動(dòng)性好，有利于兩表面分子之間的擴(kuò)散和滲透，增大接觸面積，增強(qiáng)吸附作用，有利于粘合。提高流動(dòng)性的措施：①通過塑煉，熱煉，混煉降低門尼粘度②延長膠料的焦燒時(shí)間③增加壓力5.表面分子之間的相互擴(kuò)散對(duì)粘合有何影響？答：擴(kuò)散取決于分子鏈的活動(dòng)能力及相容性，一般粘度低、相容性好，溫度高、壓力大、時(shí)間長，擴(kuò)散程度大，粘合力大。南京質(zhì)量硅膠與金屬粘合件銷售廠家</p><p
