Of rare earth isoprene rubber modified plastics technology forefront in the world

Changchun Institute of Applied Chemistry Research Institute developed 30,000 tons / year of rare earth isoprene rubber craft kits wealth of efficacy , split off last week in Beijing by the Chinese Academy of tectonic processes via effects . The Group believes that the project small private head to the international level , marking the birth of China's rare earth isoprene rubber manufacturing technology has been walking in the forefront of the world . China Rubber Association Wealth Research Center certified materials testing showed that industrial production unfamiliar isoprene rubber to create product performance exceeds the level of similar foreign-made goods , can completely replace the natural rubber used TBR tire tread .

According to reports, at present the complete set of techniques has asked 73 countries found that the patent list , consisting of modified plastics production to independent intellectual rights of crushing . The complete set of technical skills and foreign wonderful craft cf existing similar , there are double-track production to the greatest , the lowest energy and material consumption , energy saving and environmental protection features such as children , isoprene rubber per ton of manufactured goods fell to 800 yuan capital as a catalyst , the entire device analyzes the energy consumption than foreign low 20%. More necessary is the first time the project is completed pure rare earth isoprene rubber synthetic rubber for tire raw arranged manufacturing wasteland of rare earth isoprene rubber market space , get rid of the country 's natural rubber completely if asked , to deal with the overall strengthening of China's rubber industry technological level, to promote the kind of large synthetic rubber self build skills students have developed an important meaning.

According to the wonderful staff presentation skills , the skill set of modified plastics therefore developed a catalyst , polymerization, melting and post processor technology -centric, integrated elders reactor skills, actively control energy saving techniques and skills development of the domestic first set of 30,000 tons / year of rare earth isoprene rubber vocals package. Workmanship and reasonable package design , device running strong, energy and material consumption low , "three wastes " discharge less, according to the technology package has been built outside the double-track production to the greatest international property produced raw device .

The catalyst is the complete set of high technology features a great personality. RE project team presented the new olefin polymerization catalysis mechanism of double pedicle foundation, developed a catalyst with high activity and high cis- directional , low profits and the quality of its manufactured goods spread absolutely controllable elements ( modified plastics Mw / Mn ≤ 2.5 ) the nature of the catalytic activity of 0.18 kg of rare earth neodymium / xanthan gum , rare earth elements fashioned monopoly rate of 8% to 10 % to nearly 100 %, polymerization time increased from 6 to 7 hours less than the current expansion to three hours , condescend progress over foreign catalyst nearly doubled , the system works cis content of more than 97%.

The rest of the project has also developed an appropriate solution for high viscose fragmented multi- vessel continuous collusion polymerization , dissolving , after disposal and solvent recovery techniques, which collect patents and proprietary martial arts , and design , such as high viscosity fragmented rubber glue thermal equilibrium and transport projects such as problems with the technical means , the entire furnishings analyze energy consumption by 20% compared with similar foreign depression process .
