On December 4, 2021, Doublestar "Rare Earth Gold" tires successfully passed the appraisal of the authoritative expert group. The "rare earth gold" tires developed by Double Star using the "rare earth gold" rubber composite new materials will provide global users and society with the latest scientific and technological achievements created by the new double star.
Appraisal by the expert group: The new "rare earth gold" rubber composite material is made of special rare earth neodymium butadiene rubber + natural rubber + high-performance carbon black and other formulas, and is made by a special mixing process. The technology is mature and the performance is excellent. Can be promoted in batches. The "rare earth gold" tire is a product designed and produced using "rare earth gold" rubber composite material + FZW (full zero winding technology) + unique pattern. "Rare earth gold" tires have the distinctive characteristics of super fuel-efficient and super abrasion resistance. The rolling resistance can reach 3.8-4.5, and the mileage can reach 500,000 kilometers (two refurbishment can reach 1 million kilometers), which is an international leading level. Doublestar "rare earth gold" tires are expected to be put on the market in large quantities in the near future.
In March 2016, the country's first graphene tire central laboratory project started construction in Double Star. In April 2018, the project was listed as a key project by Shandong Province. At the end of 2018, Doublestar "graphene" tires were successfully developed, but they did not have large-scale market promotion due to the high cost.
Since then, Doublestar has united technical experts from Europe, the United States, and Korea to further research and develop rare earth neodymium-based butadiene rubber + natural rubber + high-performance carbon black and other formulas based on the characteristics of rare earth neodymium butadiene rubber, and make full use of Doublestar. The manufacturing advantage of the "Industry 4.0" factory has led to the development of new "rare earth gold" rubber composite materials.
At the same time, Doublestar fully combines the special needs of the Chinese market and adopts "rare earth gold" rubber composite material + FZW (full zero winding technology) + unique patterns to design and produce TBR "rare earth gold" tires that have reached the international leading level.
Rare earths are called industrial "gold", "industrial vitamins", and "mother of new materials". Rare earth is not a kind of soil, but a general term for lanthanides, scandium and yttrium in the periodic table of chemical elements. Its most important function is to significantly improve the quality and performance of other products, and form a variety of new materials and other materials with different characteristics. Material. Therefore, as an indispensable and important raw material for many major weapon systems and high-precision industries, it is a scarce and non-renewable important strategic resource in the world. China is one of the countries with the richest rare earths. China has many strategic resources such as iron ore that are poor, but rare earth resources are very rich. At present, resources are a country’s precious wealth, and also an important weapon for developing countries to safeguard their rights and fight against the power of big powers.
Rare earth neodymium, chemical symbol Nd, atomic number 60, one of the lanthanide elements, the simple substance is silver-white metal, is one of the most active rare earth metals, with a melting point of 1024°C, a density of 7.004g/cm, and paramagnetism. It can darken quickly in the air and generate oxides. Neodymium plays an important role in the field of rare earths and controls the rare earth market.
The rolling resistance of "rare earth gold" tires can be reduced to 4.5-3.8. According to comparable data and expert analysis, if a large trailer travels 1 million kilometers and uses "rare earth gold" tires with a rolling resistance of 4.5, it can save 63,000 liters of fuel (calculated at 7 yuan per liter, 440,000 liters of fuel can be saved) Yuan, which is equivalent to using 293 tires for free); the fuel consumption of a car is equivalent to a reduction of 168 tons of carbon emissions.
If the country calculates on the basis of 8 million of the above-mentioned vehicles, it can save more than 100 billion liters of fuel in a year, which is the annual oil production of nearly two Daqing oil fields. Reduce carbon emissions by more than 250 million tons, and the annual carbon dioxide absorption of more than 10 million acres of woods. Not only does it reduce the operating costs of car owners, but it also fulfills its social responsibilities.
On the other hand, if China’s annual output of truck and bus tires is calculated based on 130 million tires (with a service life of approximately 200,000 kilometers) and all double-star "rare earth gold" tires are used, calculated based on the service life of 500,000 kilometers (without refurbishment), approximately Can reduce 80 million. The 80 million tires can reduce carbon emissions by approximately 3.6 million tons a year based on the current carbon emission levels of ordinary enterprises, and greatly reduce the resource consumption of front-end raw materials.
According to relevant personnel of Double Star, relevant measures are currently being formulated to actively implement the "dual-carbon" strategy, and strive to use green energy, smart manufacturing, traditional consumption and emission reduction, biological and renewable materials, and self-developed CCER carbon trading projects. Double Star Tire will become the first company in the global automotive tire industry to achieve carbon neutrality in 2023.
This year marks the 100th anniversary of the birth of Double Star. As a state-owned enterprise with a century-old history, it has taken more than 5 years to close all the old factories and eliminate them since the start of the new journey of “second entrepreneurship and creation of a world-famous tire brand” in 2014. With all the backward tire production capacity, the first full-process "Industry 4.0" intelligent factory in the global tire industry has been built, and it is committed to creating an ecosystem of "R&D 4.0" + "Industry 4.0" + "Service 4.0". The Twinstar Tire Networking "Smart Cloud" platform has become the only tire industry to be selected as the "Internet of Things Integrated Innovation and Convergence Application Project" by the Ministry of Industry and Information Technology of the People's Republic of China. The Twinstar tire brand has been ranked first in the "Top 500 Asian Brands" Chinese tire list for many years. Doublestar Group's Yike Sida's waste tire recycling project has won the only major science and technology project in this field from the Ministry of Science and Technology.
Since the epidemic, Doublestar Tire has accelerated the pace of innovation, and is currently leading the way with digitalization and through the "tire networking" to create the world's first full life cycle green management tire company.
On January 16, 2020, Double Star Group embarked on a new journey of "Three Entrepreneurships to Create a World-Class Enterprise". After the mixed reform, we will focus on the three main businesses and model innovations of rubber tires, artificial intelligence and high-end equipment, and green ecological high-end new materials, as soon as possible to build Doublestar into a high-tech, digital and socially responsible world-class enterprise!
