          橡膠基本知識

          發布日期:2017/2/13 19:26:48

           

              橡膠,同塑料、纖維并稱為三大合成材料,是唯一具有高度伸縮性與極好彈性的高分子材料。
              橡膠的最大特征首先是彈性模量非常小,而伸長率很高。其次是它具有相當好的耐透氣性以及耐各種化學介質和電絕緣的性能。某些特種合成橡膠更具備良好的耐油性及耐溫性,能抵抗脂肪油、潤滑油、液壓油、燃料油以及溶劑油的溶脹;耐寒可低到-60℃至-80℃,耐熱可高到+180℃至+350℃。橡膠還耐各種曲撓、彎曲變形,因為滯后損失小。橡膠的第三個特征在于它能與多種材料進行并用、共混、復合,通過橡膠注射機進行改性,以得到良好的綜合性能。

             橡膠的這些基本性能,是它成為工業上極好的減震、密封、屈撓、耐磨、防腐、絕緣以及粘接等材料。   
          第一章 橡膠的種類、特性和用途   

          在全世界,橡膠(包括塑料改性的彈性體)的種類已超過100種。如果按牌號估算,實際上已超過1000種。   
          一:橡膠的分類   
          1.按原材料來源與方法   
          橡膠可分為天然橡膠和合成橡膠兩大類。其中天然橡膠的消耗量占1/3,合成橡膠的消耗量占2/3。   
          2.按橡膠的外觀形態   
          橡膠可分為固態橡膠(又稱干膠)、乳狀橡膠(簡稱乳膠)、液體橡膠和粉末橡膠四大類。   
          3.根據橡膠的性能和用途   
          除天然橡膠外,合成橡膠可分為通用合成橡膠、半通用合成橡膠、專用合成橡膠和特種合成橡膠。   
          4.根據橡膠的物理形態   
          橡膠可分為硬膠和軟膠,生膠和混煉膠等。   

          根據橡膠種類及交聯形式,利用橡膠注射機在工業使用上,橡膠又可按如下分類。   
          一類按耐熱及耐油等功能分為:普通橡膠、耐熱橡膠、耐油橡膠以及耐天候老化橡膠、耐特種化學介質橡膠等。 另一類按橡膠的軟硬程度劃分為:一般橡膠、硬橡膠、半硬質膠、硬質膠、微孔膠、海綿膠、泡沫橡膠等。   
          橡膠工業制品是除輪胎、膠管、膠帶等之外的其他橡膠制品。主要包括以下幾類。   
          一:橡膠密封制品   _
          橡膠密封制品包括O型橡膠密封圈、旋轉軸唇形密封件(油封)、復合密封、異形斷面橡膠密封件、制動皮碗皮圈、汽車制動氣室橡膠隔膜、橡膠密封條、橡膠防塵套(罩)、皮膜、水封制品、吸水膨脹橡膠、橋面橡膠伸縮縫等。   
          二:橡膠減震制品   
          橡膠減震制品包括橡膠減震器、橡膠氣彈簧、橡膠彈性聯軸節、可屈撓橡膠接頭、橡膠護舷、汽車用橡膠減震器、火車機車用橡膠減震器、橡膠注射機、橡膠軌枕墊、橋梁橡膠支座等。   
          三:硬質橡膠   
          四:橡膠海綿制品   
          五:膠板與防水卷材   
          六:膠輥   
          七:紡織用橡膠制品   
          八:印刷工業用橡膠制品   
          九:橡膠襯里   
          十:橡膠電絕緣制品   
          十一:軟木橡膠   

               第三章 橡膠的性能及測定   
          硫化橡膠的性能主要指機械性能、耐熱性能、耐寒性能、耐介質性能、耐磨耗性、耐天候老化性、阻燃性能和電絕緣性能等,它們對橡膠制品的使用性能和產品質量具有決定性的影響。   
          硫化橡膠的性能與其配方組成密切相關,選擇不同的配方組成,可以使硫化橡膠的性能在較寬的范圍內變化。因此,研究性能與配方組分之間的關系,是配方設計的主要內容之一。   
          橡膠的性能可分為兩大類,及結構性能和功能特性,結構性能是指高彈性和強度等力學性能;功能特性指橡膠的物理特性和化學特性,如耐介質、電絕緣性、耐化學腐蝕性等。在橡膠制品中,有的以利用前一類性能為主,如減震制品、密封制品等;有的利用后一類性能為主,如水封(耐水性)和電纜護套(電絕緣性)等。但在所有性能中,結構性能既機械力學性能最為重要。因為它是一切性能的基礎。
