Guorubber Center liquid gold new energy vehicle rubber products and tire application research and development platform was established

In order to adapt to the development of the new energy vehicle industry, the National Rubber and Tire Engineering Technology Research Center recently established a liquid gold new energy vehicle rubber products and tire application research and development platform
with the approval of the competent authorities at the higher level.

In recent years, as a national technology research and development and scientific research management platform for the rubber tire industry, the National Rubber Center has carried out a lot of research work on rubber products and tires for new energy vehicles, and has achieved a series of major technical achievements
。 In the future, the platform will comprehensively carry out more targeted key components of new energy vehicles, focusing on key areas and directions such as iterative optimization of "liquid gold" technology, development of new rubber materials, formula design, finite element simulation analysis, new product development, standard system construction and battery system sealing materials, accelerate the research and development of major common technologies and key core technologies, solve the green and sustainable development of the whole life cycle of rubber products and tires of new energy vehicles, and promote the overall level of rubber and tire industry to become world-class
。

It is understood that there are great differences
between new energy vehicles and traditional vehicles in terms of power source and operating conditions.
Taking tires for new energy vehicles as an example, due to the contradiction between battery capacity and single cruising range, tires are required to have lower rolling resistance to improve endurance; Because the body weight is larger than that of conventional cars, tires are required to provide higher load capacity and stronger braking performance; Due to the large initial torque of the motor and the fast acceleration of the vehicle, the tire is required to have better grip performance and wear resistance; Because the motor is less noisy, the requirements for tire noise are more stringent
.
There are many mutual constraints between the above performances, which puts forward new challenges and higher requirements
for the formula and structural design of special tires for new energy vehicles.
The new liquid gold material technology of the National Oak Center can provide strong support
for these new requirements of new energy vehicles.

Liquid gold technology is a major original innovation in the field of rubber tires in the world, which solves the technical problem that rubber raw materials cannot be evenly dispersed at the nanoscale, fundamentally solves the "devil's triangle" problem that the three key properties of tires - rolling resistance, wet braking performance and wear resistance cannot be improved at the same time, and realizes the comprehensive improvement
of tire products such as energy saving, safety, environmental protection and quietness 。 ERANGE| for new energy vehicles Compared with international first-line brands, EV products have a 5% shorter dry braking distance, a 15% reduction in rolling resistance, and a 7% increase in cruising range, which can fully meet the performance requirements
of new energy vehicles for tires.

In addition, the National Oak Center has also successfully overcome the key technology of air spring airbags, prepared ultra-high-performance air spring products, and carried out real vehicle tests with many OEMs, with a relatively mature technology accumulation
.
At present, after testing, the flexural cracking performance of airbag rubber material is greater than 40 million times, and the durability test of air spring assembly suspension at high temperature (80 °C) is greater than 18 million times, far exceeding more than 20% of international first-line brands, and the products have been equipped with some domestic high-end models, realizing domestic substitution
.
At the same time, a number of other sealed, high-temperature, low-temperature resistant products have also made breakthroughs
.

The platform also has a strong talent guarantee, bringing together dozens of domestic and foreign experts
, including Wang Mengjiao, chief scientist of China Oak Center, Xu Shuliang, chief tire expert, Wang Aichun, chief product expert, Xia Xunmao, chief tire consultant, Chang Dayong, professor of Shenyang Rubber Research and Design Institute, and Sheng Baoxin, dean of the Chinese Academy of Sciences.
