Description

technical field [0001] The invention relates to the field of rubber-plastic alloy materials, in particular to a rubber-plastic alloy material with excellent oil resistance and corrosion resistance and a preparation method thereof. Background technique [0002] Natural rubber has excellent properties such as resilience, insulation, water resistance and plasticity, and after proper treatment, it also has valuable properties such as oil resistance, acid resistance, alkali resistance, heat resistance, cold resistance, pressure resistance, wear resistance, etc. Therefore, it has Wide range of uses. Natural rubber has low tensile strength and hardness when used alone, and is limited in use. More than 70% of the rubber in the existing market is processed and used in the form of rubber or rubber and plastic.

AI Technical Summary

Problems solved by technology

[0003] Rubber-plastic alloy (NBR / PVC) is a kind of nitrile rubber (NBR) as the main base material, which is effectively modified by adding 30-50% mass fraction of polyvinyl chloride (PVC) and blended under specific process conditions. The resulting material rubber-plastic alloy has the dual characteristics of nitrile rubber and neoprene rubber. Through the closure of the double bond on the long chain of nitrile rubber by polyvinyl chloride macromolecules, the rubber-plastic alloy is endowed with excellent resistance to natural aging and ozone aging. At the same time, it not only retains the excellent oil resistance of nitrile rubber, but also has excellent solvent and chemical corrosion resistance and high mechanical properties, and has good dynamic flexibility. And self-extinguishing, nowadays, rubber-plastic alloy rubber has important commercial value and is widely used in the automobile industry and manufacturing industry. However, due to the poor thermal stability and impact resistance of polyvinyl chloride, whether it is hard or soft High-quality PVC is prone to brittleness during use, which will restrict the performance of the manufactured rubber-plastic alloy and affect its further promotion and application
