Description

一种生物环保型柴油抗凝剂
技术领域
本发明涉及燃油添加剂的技术领域，具体的说是一种生物环保型柴油抗凝剂。
背景技术
柴油在较低温度下之所以会凝固，是由于柴油中含有一定量的蜡（即正构烷烃），通常柴油中的正构烷烃含量约为15%-30%，当柴油被冷却时，蜡晶会迅速长大，首先形成平面状结晶，这些结晶相互联结，已至形成三维网状结构，把油包在其中，使其失去流动性而呈现凝固状态。柴油机在工作时，柴油经粗、细滤清器，再经过高压泵、喷油嘴被喷入气缸。当柴油温度降至冷滤点温度时，所形成的蜡晶就会堵塞滤清器而影响油路的正常供油，进而影响发动机工作。
发明内容
本发明的目的就是针对柴油在较低温度下之所以会凝固，影响发动机工作之问题，而提供一种生物环保型柴油抗凝剂。
本发明由油酸甲酯和聚醋酸乙烯酯组成；按体积配比为：油酸甲酯50-70份，聚醋酸乙烯酯20-50份。
聚醋酸乙烯酯由聚丙烯酸高碳醇酯代替；按体积配比为：油酸甲酯50-70份，聚丙烯酸高碳醇30-50份。
本发明由油酸甲酯、聚丙烯酸高碳醇酯和聚醋酸乙烯酯组成；按体积配比为：油酸甲酯50-70份，聚丙烯酸高碳醇酯20-50份，聚醋酸乙烯酯30-50份。
聚丙烯酸高碳醇酯由醋酸乙烯酯-富马酸酯共聚物、烯基丁二酰胺酸盐、马来酸酐类共聚物或极性含氮化合物替代；或由醋酸乙烯酯-富马酸酯共聚物、烯基丁二酰胺酸盐、马来酸酐类共聚物和极性含氮化合物任意组配而成的混配物替代。
油酸甲酯不饱和度>90%，碘值>120，冷滤点<-12℃。
本发明的优点是该柴油抗凝剂创造性的使用了油酸甲酯，其和聚丙烯酸高碳醇酯及聚醋酸乙烯酯协同效应明显，显著提高柴油的低温流动性能，保障发动机冷启动顺畅，同时具有良好的低温润滑性能，明显减少积碳的产生，有效解决气温骤降、跨地区行驶给行车和储运带来的困惑。
具体实施方式
本发明由油酸甲酯和聚醋酸乙烯酯组成；按体积配比为：油酸甲酯50-70份，聚醋酸乙烯酯20-50份。
聚醋酸乙烯酯由聚丙烯酸高碳醇酯代替；按体积配比为：油酸甲酯50-70份，聚丙烯酸高碳醇30-50份。
本发明由油酸甲酯、聚丙烯酸高碳醇酯和聚醋酸乙烯酯组成；按体积配比为：油酸甲酯50-70份，聚丙烯酸高碳醇酯20-50份，聚醋酸乙烯酯30-50份。
聚丙烯酸高碳醇酯由醋酸乙烯酯-富马酸酯共聚物、烯基丁二酰胺酸盐、马来酸酐类共聚物或极性含氮化合物替代；或由醋酸乙烯酯-富马酸酯共聚物、烯基丁二酰胺酸盐、马来酸酐类共聚物和极性含氮化合物任意组配而成的混配物替代。
油酸甲酯不饱和度>90%，碘值>120，冷滤点<-12℃。
