Abstract

本发明公开了一种耐油耐磨橡胶，所述的橡胶含有以下物质：天然橡胶、胎面胶、氧化锌、硬脂酸、碳黑N330、石蜡、古马隆、硫黄、沥青、2,2-二噻吩基乙醇酸甲酯、4-硝基邻苯二甲酸二甲酯、3-[(3-氨基-4-甲基氨基苯甲酰)吡啶-2-基氨基]丙酸乙酯、防老剂、促进剂。本发明与现有技术相比，通过在配方中加入2,2-二噻吩基乙醇酸甲酯、4-硝基邻苯二甲酸二甲酯、3-[(3-氨基-4-甲基氨基苯甲酰)吡啶-2-基氨基]丙酸乙酯，使天然橡胶的耐油性能提高到了5-6%。

Description

一种耐油耐磨橡胶
技术领域
本发明涉及橡胶，特别涉及用于管道衬套的耐油耐磨橡胶。
背景技术
在油田的管道运输中，所运输的介质为油和矿砂的混合物，故其管道衬套所用的橡胶通常是含有胎面胶的天然橡胶，虽然上述橡胶具有耐磨性能，但其耐油性很差，其耐油性能只能达到15%以上。
发明内容
本发明所要解决的技术问题是提供一种耐油性能达到5-6%的耐油耐磨橡胶。
本发明解决技术问题的技术方案为：一种耐油耐磨橡胶，含有以下物质及重量份：
Figure BDA0000182124321
Figure BDA0000182124322
所述的防老剂为：2,2,4-三甲基-1,2-二氢喹啉聚合物，防老剂RD。
所述的促进剂为:4-4'-二硫化二吗啉（DTDM）
本发明的制备方法与现有的橡胶的制备方法相同。
本发明与现有技术相比，通过在配方中加入2,2-二噻吩基乙醇酸甲酯，4-硝基邻苯二甲酸二甲酯、3-[(3-氨基-4-甲基氨基苯甲酰)吡啶-2-基氨基]丙酸乙酯，使天然橡胶的耐油性能提高到了5-6%。
具体实施方式：
下面结合实施例对本发明作详细的说明。
实施例1：
Figure BDA0000182124323
Figure BDA0000182124324
实施例2：
Figure BDA0000182124325
实施例3
Figure BDA0000182124326
Figure BDA0000182124327
本发明的耐油性能按照ASTM  D 471标准进行检测，单位为%；
实施例1、2、3的耐油性能（油浸泡后的膨胀率）分别为5.8%、5.7%、5.9%。

Claims (3)
