Description

一种增强TFT-LCD显示屏导电性的橡胶
技术领域
本发明涉及TFT-LCD显示屏技术领域，具体涉及一种增强TFT-LCD显示屏导电性的橡胶。
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，导电橡胶通常是指体积电阻在109的欧姆厘米以内，由于橡胶是优良的绝缘体，体积电阻大于1014左右。导电炭黑填充的导电橡胶，体积电阻通常可保持在几千欧姆，由于现有的配方中使用了单一的炭黑，其抗拉强度只能达到12Mpa，远远不能满足实际的需要。
发明内容
本发明旨在提供了一种增强TFT-LCD显示屏导电性的橡胶。
本发明提供如下技术方案：
一种增强TFT-LCD显示屏导电性的橡胶，其是由如下重量份数的原料组成：导电橡胶180-250份、偶联剂10-32份、增塑剂20-80份、硫化剂30-50份、防老剂20-50份、阻燃剂10-30份、补强剂20-40份和导电填料10-30份。
所述导电橡胶的材质为硅橡胶、氟橡胶、氟硅橡胶、乙丙橡胶、三元乙丙橡胶、丁苯橡胶、顺丁橡胶、异戊橡胶、丁腈橡胶、氯丁橡胶、氯化聚乙烯、氯磺化聚乙烯、丙烯酸酯橡胶、聚硫橡胶、聚氨酯橡胶，或者这些橡胶的共混物和改性产物。
所述偶联剂为γ-巯丙基三甲氧基硅烷。
所述导电填料是导电炭黑、碳纤维、石墨、碳纳米管、石墨烯、金属粉末、金属短纤维、金属涂覆的粉末、微珠或短纤维、具有导电性的氧化物粉末。
所述导电橡胶是多孔型导电橡胶；导电橡胶中的孔洞是完全或部分连通的并有部分孔洞外露于导电橡胶表面。
一种增强TFT-LCD显示屏导电性的橡胶的制备方法，将双辊开炼机的前辊温控制在120℃，后辊温控制在110℃，将导电橡胶、偶联剂、增塑剂、硫化剂、防老剂、阻燃剂、补强剂和导电填料依次加入双辊开炼机中，薄通5次，然后静置3-4小时，转移到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10min。
所述多孔型导电橡胶是用高速钻孔机进行钻孔的机加工方法得到的；在导电橡胶热硫化成型时，将若干外接圆直径0.08-2mm的表面光滑的金属丝拉直并埋于热硫化模腔中，金属丝之间是平行的或交错的；导电橡胶在模腔中热硫化成型后，将金属丝拨出，即得到多孔型橡胶。
与现有技术相比，本发明的有益效果是：本发明通过导电橡胶热硫化成型，将若干外接圆直径0.08-2mm的表面光滑的金属丝拉直并埋于热硫化模腔中，金属丝之间是平行的或交错的；导电橡胶在模腔中热硫化成型具有增强的导电性，能提高TFT-LCD显示屏的导电性能，十分适于用在通讯、电厂等领域。
