Vegetable Oil | Beijing University of Chemical Technology! Tire with vegetable oil environmental protection plasticizer successfully developed

PlasticizerIt plays a very important role in the rubber industry, which can reduce rubber viscosity, thereby improving processing performance and reducing processing energy consumption. In 2019, the global use of rubber plasticizers reached 10.3 million tons. However, most of the commonly used rubber plasticizers are non-renewable petroleum-based small molecule plasticizers, which produce a large amount of volatile organic compounds (VOC) emissions during rubber vulcanization, causing serious pollution to the environment; at the same time, some petroleum-based plasticizers contain carcinogenic polycyclic aromatic hydrocarbons, which are extremely harmful to human health.

With the society's emphasis on sustainable development and environmental protection, the development of VOC-free, renewable rubber plasticizers that meet the needs of the new era has become one of the important routes to achieve sustainable development of the rubber industry.Starting from 2012Foreign tire giants such as Goodyear, Michelin and Hantai have all put forwardvegetable oil plasticizerThe concept.

Advanced Elastomer Materials Research Center, Beijing University of Chemical TechnologySince 2009, we have been committed to the development of green rubber plasticizers. Vegetable oil is non-toxic, easy to obtain, renewable, high thermal stability, good plasticizing effect, and does not produce VOC emissions during tire processing and use. However, when vegetable oil is directly used as rubber plasticizer, its double bond will affect the rubber cross-linking, resulting in the decline of mechanical properties of rubber materials.Wang Chao, Associate Professor of Advanced Elastomer Materials Research Center, Beijing University of Chemical TechnologyA new method of vegetable oil modification is proposed to reduce the content of active double bonds in vegetable oil and reduce or even avoid the influence of vegetable oil on rubber crosslinking.Beijing University of Chemical Technology teamed up with Anhui Gurite New Materials Technology Co.From the modification of vegetable oil and the batch preparation of modified vegetable oil, to the breakthrough of the processing technology of modified vegetable oil in tire tread materials, to the performance evaluation of tires, the vegetable oil labeling method snow tires and high oil volume winter tires have been successfully developed.The rolling resistance and high-speed performance of vegetable oil tires are equivalent to those of aromatic oil tires, and the low temperature resistance is better.

Dr. Danling Wang of Zhongce Rubber Group Co., Ltd.It is committed to the application development of modified vegetable oil in tires, and it is believed that the successful development of vegetable oil plasticizer can solve the VOC emission of tires at the plasticizer level. For example, the boiling point of aromatic oil is about 200 ℃. If the quality of aromatic oil is poor, the boiling point can be as low as about 100 ℃, while the boiling point of modified vegetable oil is about 400 ℃. According to the national standard and test method of odor test, the odor grade of modified vegetable oil tread rubber material is lower than that of environmental protection aromatic oil rubber. Modified vegetable oil tires meet the requirements of environmental protection and are a potential bio-based environmentally friendly plasticizer for the next generation of tires.

Chairman Shao Jin of Anhui Gruite New Material Technology Co., Ltd., focusing on green tire additives and related materials, andBeijing University of Chemical Technology TightIn 2019, we transferred the vegetable oil modification patent with Beijing University of Chemical Technology. The two sides worked together to overcome a series of technical problems and successfully developed this new type of modified vegetable oil plasticizer product. This product has been proved by many experiments that it can not only meet the performance requirements in the tire industry production, replace the petroleum-based aromatic oil plasticizer, but also meet the new national demand for environmental protection and sustainable development. It will be used in the future rubber and tire industry. China has huge development potential and broad market prospects.
