High-performance synthetic rubber industrialization project passed the evaluation

Recently, the national key research and development plan project "Key Technologies for Industrialization of High-Performance Synthetic Rubber" led by PetroChina Co.
, Ltd.
passed the comprehensive performance evaluation of the subject
.

The evaluation expert group is composed of 9 experts including Zhang Liqun, academician of the Chinese Academy of Engineering, and Professor Zhang Haibo, a responsible expert of the Ministry of Science and Technology.
Zhang Liqun is the leader of the expert group
.
The expert group conducted a comprehensive performance evaluation on the completion of the assessment indicators, achievement level, innovation, talent training, organization and management of the four topics under the project.
Talent and team training have achieved remarkable results, and the organization and management are efficient
.

On behalf of the project team, Gong Guangbi, the project leader, reported the project to the expert group
.
The project proposed and formed the molecular design method and sequence structure control principle of functionalized solution-polymerized styrene-butadiene rubber, the dual control preparation process of bromobutyl rubber "microdroplet extraction" and "calcium stearate neutralization", rare earth catalytic mechanism and 4 theoretical innovations including polymerization mechanism; breakthroughs in 3 key technologies of branching agent preparation, engineering scale-up, and advanced tire processing; achieved in-situ preparation of tubular reactors with highly active functionalized initiators, suitable for high viscosity extreme flow ratios Three key equipment innovations including the 10,000-ton-level microreactor and the first domestic (150 kg/h) butyl rubber industrial sideline device; functionalized solution-polymerized styrene-butadiene, narrow-distributed rare earth cis-butadiene, and star-branched butylene have been realized.
Demonstration of 10,000-ton production of 4 high-performance rubber base materials, bromobutyl and bromobutyl, and production and application demonstration of 2 products of high-performance tire and long-life curing bladder.
The prepared 225/55R16 tire product meets EU tire labeling regulations A/ Grade B, the average service life of the vulcanized bladder is more than 600 times
.

The expert group suggested that the project team continue to increase the industrial scale of functionalized solution-polymerized styrene-butadiene rubber functional monomers and the industrial scale of high-performance rare-earth cis-butadiene rubber, speed up the large-scale production process of high-end tire products, and expand the new products developed by the project in applications in other fields
.

He Shengbao, Dean of the Research Institute of Petrochemical Industry, said that from project initiation to completion, the four subjects of performance evaluation were all excellent, and the entire project team fully reflected the excellent work style and persistent pursuit
.
This time, the national key R&D project "Key Technologies for Industrialization of High-Performance Synthetic Rubber" undertaken by PetroChina has completed the performance evaluation of the subject
.
