Description
技术领域 technical field
本发明涉及一种橡胶材料，特别是涉及一种高丙烯腈含量的浅色NBR/PVC耐油橡胶材料。 The present invention relates to a rubber material, in particular to a light-colored NBR/PVC oil-resistant rubber material with high acrylonitrile content.
背景技术 Background technique
丁腈橡胶(NBR)具有优良的耐油性、耐热性和物理机械性能，但其耐臭氧老化性能较差；而通用合成树脂聚氯乙烯(PVC)则具有优异的阻燃性、自熄性以及耐臭氧老化、耐化学腐蚀性、电绝缘性、化学稳定性和热塑性，但其韧性低，不耐冲击，耐热性能较差。由NBR与PVC共混制成的复合材料，综合了两者的性能优势，弥补了各自的缺陷，成为一种重要的新型橡塑并用材料，也是橡塑并用的先驱。 NBR及PVC皆为极性高聚物，二者溶解度参数相近，相容性甚好，可以任意比例掺混，因此既可用PVC增强和改性NBR，也可用NBR对PVC进行增韧。NBR与PVC共混制成的共混硫化胶已是目前橡塑并用的主要胶种，这种共混硫化胶具有良好的物理机械性能。NBR/PVC热塑性弹性体因具有NBR突出的弹性、耐油性和PVC的可塑性、耐候性、耐化学药品性等特性，在燃油胶管、电线电缆护套、印刷胶辊、密封制品、尤其是汽车零部件等方面得到了广泛的应用。 浅色橡胶制品的制造是一项关键技术。浅色橡胶制品可以大大的扩大橡胶材料的适用范围，可以与白色和其他浅色建材或产品结合使用。 Nitrile rubber (NBR) has excellent oil resistance, heat resistance and physical and mechanical properties, but its ozone aging resistance is poor; while general-purpose synthetic resin polyvinyl chloride (PVC) has excellent flame retardancy and self-extinguishing properties As well as ozone aging resistance, chemical corrosion resistance, electrical insulation, chemical stability and thermoplasticity, but its toughness is low, it is not impact resistant, and its heat resistance is poor. The composite material made of NBR and PVC blends combines the performance advantages of the two and makes up for their respective defects. It has become an important new rubber-plastic composite material and a pioneer of rubber-plastic composite materials. Both NBR and PVC are polar high polymers. The solubility parameters of the two are similar, and the compatibility is very good. They can be mixed in any proportion. Therefore, PVC can be used to strengthen and modify NBR, and NBR can also be used to toughen PVC. The blended vulcanizate made of NBR and PVC is currently the main type of rubber used in combination with rubber and plastic. This blended vulcanized rubber has good physical and mechanical properties. NBR/PVC thermoplastic elastomers are widely used in fuel hoses, wire and cable sheaths, printing rollers, sealing products, especially automotive parts due to their outstanding elasticity, oil resistance, and plasticity, weather resistance, and chemical resistance of PVC. Components and other aspects have been widely used. The manufacture of light-colored rubber products is a key technology. Light-colored rubber products can greatly expand the scope of application of rubber materials, and can be combined with white and other light-colored building materials or products.
关于NBR/PVC共混胶有部分文献和专利进行了报道，例如专利CN102993500A介绍了一种NBR/PVC共混橡塑材料及其制备方法，得到臭氧性、耐油性良好的共混胶。NBR与PVC共混胶虽然有了一定的研究，但是对于浅色NBR/PVC研究甚少，有关高丙烯腈含量的浅色NBR/PVC耐油性能的综合研究更是鲜见报道，所以对高丙烯腈含量的浅色NBR/PVC共混橡胶材料的研究很有意义。 Some literatures and patents have reported about NBR/PVC blended rubber. For example, patent CN102993500A introduces a NBR/PVC blended rubber-plastic material and its preparation method, and obtains a blended rubber with good ozone and oil resistance. Although there has been some research on NBR and PVC blends, there are few studies on light-colored NBR/PVC, and there are few reports on the comprehensive research on the oil resistance of light-colored NBR/PVC with high acrylonitrile content. The study of light-colored NBR/PVC blended rubber materials with nitrile content is very meaningful.
