NBR is an anti-oil rubber, and its resistance to aging and wear resistance are much better, it is widely used in oil drilling, petrochemical, automotive and other industries to manufacture tubing, rubber rollers, tape, cables, rubber lining, capsule, diaphragm and other oil products, such as oil seals, gaskets, sealing gaskets and other oil products. Nitrile rubber products on the domestic market mainly showed the following characteristics, including the shortage of domestic nitrile market, the gap is relatively large; Domestic market confront with great competition, product quality and service highlight its status, the foreign company’s products and technology bundling model has been widely implemented, and achieved good results; As a major domestic supplier of nitrile rubber, Lanzhou Petrochemical invested on after-sales service to a certain extent in recent years and gained a good effect, but only do some research on the processing and application properties of their own products, while knowing a little about the quality and the processing and application properties of foreign brands of nitrile rubber.The domestic nitrile rubber user applied a rigid formula only according to some certain grades, ignoring the differences in the quality of the rubber itself, the final imbalance caused by the application of formula, that is the existence of differences between the intrinsic quality of Lanzhou petrochemical products and processing of application system with the similar foreign products. Therefore, there is a certain resistance on our way to continue to develop the domestic NBR market.To take full advantage of the important role of the nitrile rubber plant petrochemical company in the domestic rubber industry, long-term stably occupy the end-user, increase market share rate, lay a good foundation for the Lanzhou Petrochemical 50,000 tons/year unit NBR products sales at the same time, our project do the quality analysis research on the Lanzhou Petrochemical nitrile products and imported NBR products sold on the market, and find its quality differences, provide a basis for the improvement of production and technical support for the downstream users’production.We use infrared, GPC and other methods to complete the test of 15 brands NBR’s micro-structure, molecular weight and molecular weight distribution from domestic market of of nitrile rubber, comparatively study to understand the level of development of foreign nitrile rubber and the actual quality of products, know our Domestic nitrile rubber’s overall quality level and quality characteristics. Further more, our study also compared 15 brands of nitrile rubber processing applications, processing technology, mix properties, mechanical properties of vulcanized rubber, Identify the advantages, disadvantages and measures to improvement on the domestic NBR, to strengthen the Lanzhou Petrochemical nitrile rubber after-sales technical service capabilities.
