Linglong Reaches Another Milestone in Graphene Research

Linglong Milestone Graphene Research

This research is seen as another milestone for Linglong Tire after the first low rolling resistance concept tyre was made and published in an international authoritative academic journal in 2015.

Linglong’s Investment in Graphene Research Pay Off

The research on ‘large-scale application of graphene rubber composites’, which is conducted jointly by Beijing Tiancheng Linglong Tire Co, Ltd, a wholly-owned subsidiary of Linglong Tire, and Beijing University of Chemical Technology, has passed the audit and acceptance held by the Beijing Municipal Science & Technology Commission (BMSTC) on 28thJanuary , 2019.

Besides China’s leading experts from Tsinghua University, those from the Peking University, National Center for Nanoscience and Technology (NCNT), Beijing Normal University, Beijing Research Institute of Sinopec (BRIS), among others, also participated in the audit.

This research is seen as another milestone for Linglong Tire after the first low rolling resistance concept tyre was made and published in an international authoritative academic journal in 2015. Guo Baochun, a professor from South China University of Technology, provided the key technical support with his team and the trial production of graphene-enhanced tyre was completed in the semi-steel radial tyre production line of Zhaoyuan, Linglong Tire’s production base.

The achievements of this research are as follows: the team jointly developed the graphene pretreatment technology, which lowered the production cost for graphene pretreatment. After the pretreatment body was applied in the tread formula, the graphene-enhanced tyre could be produced without changing the existing tyre production process and equipment in addition to some appropriate process adjustment, so as to ensure the feasibility of the industrial production process within controllable cost; the trial-produced tyres achieved breakthroughs in key performance such as fuel efficiency, safety and anti-static, and successfully demonstrated the application value of graphene in energy-saving tyres.

More specifically, the fuel-efficient grade of Linglong‘s graphene tyre is close to grade A of the EU Tire Labeling Regulation; also, its wet grip performance is estimated to achieve level A of EU Labeling, and its comprehensive performance has reached the international advanced level. In addition, the abrasion resistance and thermal conductivity of the tyres have varying degrees of improvement compared with the high-performance green tyres in the market.

As a material, graphene has the advantage of ultra-high conductivity and thermal conductivity. A small amount of graphene in polymer composites could significantly improve the ultra-high and thermal conductivity of the materials. Also, the characteristics of ultra-high strength and super-large specific surface area of graphene enable it to effectively improve the abrasion resistance of rubber composites. Through micro interface technology originally developed by the research team, the fuel consumption of a grapheme tyre could be effectively reduced. The introduction of graphene into tyre production would have a profound impact on the development of Chinese tyre technology and graphene industry.



课题成果的顺利验收,是玲珑轮胎继2015年制备出、在国际权威学术期刊发表的首条低滚阻概念轮胎之后,又一里程碑进展。 本课题由山东玲珑轮胎股份有限公司全资子公司北京天诚玲珑轮胎有限公司与北京化工大学共同承担。华南理工大学郭宝春教授团队给予关键技术支持,最终在山东玲珑轮胎股份有限公司招远半钢子午线轮胎生产线完成轮胎试制。
