Description

一种导电橡胶材料
技术领域
本发明涉及橡胶领域,具体的说,本发明涉及一种导电橡胶材料。
背景技术
橡胶是具有可逆形变的高弹性聚合物材料,在室温下富有弹性,在很小的外力作用下能产生较大形变,除去外力后能恢复原状。橡胶属于完全无定型聚合物,它的玻璃化转变温度低,分子量往往很大,大于几十万,但是现有技术要使橡胶具备理化特性良好,具有很强的耐热、耐水、耐腐蚀、耐老化等方面的特点,那么橡胶产品在生产过程中,其工艺生产技术的要求就比较高,而且橡胶的生产制备方法较为复杂,生产污染严重且制备率较低,20世纪60年代开发的热塑性橡胶,无需化学硫化,而采用热塑性塑料的加工方法成形,橡胶按使用又分为通用型和特种型两类,是绝缘体,不容易导电,但如果沾水或不同的温度的话,有可能变成导体,导电是关于物质内部分子或离子的电子的传导容易情况,橡胶的分子链可以交联,交联后的橡胶受外力作用发生变形时,具有迅速复原的能力,并具有良好的物理力学性能和化学稳定性,橡胶是橡胶工业的基本原料,广泛用于制造轮胎、胶管、胶带、电缆及其他各种橡胶制品,橡胶按原料分为天然橡胶和合成橡胶,按形态分为块状生胶、乳胶、液体橡胶和粉末橡胶,乳胶为橡胶的胶体状水分散体,液体橡胶为橡胶的低聚物,未硫化前一般为粘稠的液体,粉末橡胶是将乳胶加工成粉末状,以利配料和加工制作。
发明内容
本发明的目的在于提供一种导电橡胶材料。
为了实现本发明的目的,本发明提供一种导电橡胶材料,由下列重量份的原料制成:硅橡胶50-150份、导电颗粒1-10份、导电石墨3-7份、补强剂10-20份、碳酸钙2-10份、防老剂10-20份、邻苯二甲酸二丁酯3-5份、二乙基二硫代氨基甲酸锌1-4份、2-硫醇基咪唑啉1-4份、硫化剂3-5份。
优选地,本发明所述的导电橡胶材料由下列重量份的原料制成:硅橡胶80份、导电颗粒6份、导电石墨3份、补强剂15份、碳酸钙5份、防老剂15份、邻苯二甲酸二丁酯3份、二乙基二硫代氨基甲酸锌2份、2-硫醇基咪唑啉2份、硫化剂5份。
优选地,所述导电颗粒为N-{3-[(4-氨基-7H-吡咯并[2,3-d]嘧啶-5-基)乙炔基]苯基}-3-氯苯甲酰胺颗粒。
优选地,所述补强剂为炭黑。
优选地,所述防老剂为N-苯基-α-苯胺。
优选地,所述硫化剂为过氧化二异丙苯。
本发明所述的导电橡胶材料具体耐热、耐寒、耐臭氧、耐老化性,可广泛用于橡胶开关、接点橡胶、压力传感器、燃烧电线芯材等,其导电性能优良,不会出现开裂。
具体实施方式
以下通过具体实施方式的描述对本发明作进一步说明,但这并非是对本发明的限制,本领域技术人员根据本发明的基本思想,可以做出各种修改或改进,但是只要不脱离本发明的基本思想,均在本发明的范围之内。
实施例1
称取硅橡胶800克、N-{3-[(4-氨基-7H-吡咯并[2,3-d]嘧啶-5-基)乙炔基]苯基}-3-氯苯甲酰胺颗粒60克、导电石墨30克、炭黑150克、碳酸钙50克、N-苯基-α-苯胺150克、邻苯二甲酸二丁酯30克、二乙基二硫代氨基甲酸锌20克、2-硫醇基咪唑啉20克、过氧化二异丙苯50克;
将双辊开炼机的前辊温控制在120℃,后辊温控制在110℃,将上述材料加入双辊开炼机中,薄通5次,然后静置5小时,转移到QLB-D400X400X2型平板硫化机中压制片材,平板硫化机模板温度为140℃,模压力为0.5Mpa,模压时间10分钟。
实施例2
按照和实施例1相同的方式制备导电橡胶材料,不同之处在于不使用N-{3-[(4-氨基-7H-吡咯并[2,3-d]嘧啶-5-基)乙炔基]苯基}-3-氯苯甲酰胺。
实验例
性能测试
(1)ASTMD412-1998(2002)来测定橡胶的拉伸强度;
(2)GB/T1692-1992来测定橡胶绝缘电阻率。
结果
实施例1的样品:拉伸强度为23.6Mpa,体积电阻率为3.9×107Ω·cm。
实施例2的样品:拉伸强度为15.8Mpa,体积电阻率为8.8×109Ω·cm。
由上述结果可见,在加入导电颗粒之后,橡胶的强度和导电性得到显著增强,并且加入前和加入后结果进行比较,差异具有统计学意义(P<0.05)。
