Exploring the Mysterious Resin in the "Flying" Torch——Into Cube Chemical (Shanghai) Co., Ltd.

On the evening of March 13, the Beijing 2022 Winter Paralympic Games came to a successful conclusion as the main torch of the Winter Paralympic Games, which had been burning for nine days, was slowly extinguished
.

The "Flying" torch in the center of the "Snowflake" main torch platform has once again become the focus of attention

According to Liu Zhangyou, general manager of the company, the mysterious resin used in the "flying" torches of the Beijing Winter Olympics and Paralympics is called polysilazane resin, commonly known as high temperature non-combustible resin
.

The resin combines the characteristics of super adhesion of organic substances and super high temperature resistance of inorganic substances, and combines the characteristics of corrosion resistance, wear resistance, anti-fouling and waterproofing, and can be used in aerospace, transportation, and new energy infrastructure.

The shell of the "Flying" torch of the Beijing Winter Olympics is made of carbon fiber reinforced resin matrix composite material
.

The carbon content of carbon fiber materials is more than 90%, which has two characteristics of strong tensile strength of carbon materials and soft processability of fibers

Previously, this type of carbon fiber reinforced resin-based composite material independently developed in China could only withstand temperatures around 200°C, and would be defeated when it encounters high temperatures
.

The combustion port of the "Flying" torch is between the inner shell and the outer shell, and the carbon fiber shell is required to be able to withstand high temperatures above 800 °C

Shanghai Petrochemical, which undertakes the development of the carbon fiber shell for the Beijing Winter Olympics torch, is worried about finding high temperature-resistant resins
.

Polysilazane resin technology is one of the technical solutions to solve the problem of high temperature resistance, but because the technology of this project is used in military, semiconductor and other fields abroad, it has become a "stuck neck" technology

"The third-generation polysilazane resin we developed in 5 years can withstand high temperatures of up to 1200°C, while the combustion temperature of hydrogen is generally 800°C, which can meet the requirements of the Beijing Winter Olympics torch carbon fiber shell material
.

" Liu Zhangyou Proud to say

At that time, Cooper Chemical had already cooperated with Shanghai Carbon Fiber Composite Materials Innovation Research Institute
.

As the support of Kube, the team of Dr.

　　Through countless experiments, they finally successfully synthesized polysilazane, and withstood the test of continuous combustion for 16 days, thus achieving a technological breakthrough in high-performance high-temperature non-combustible "polysilazane" resin, and also for the complete solution of China's problems in Naite.
The common technical problems in the field of high temperature special resins have laid the foundation
.

The bottleneck of "Flying" torch has also been solved

　　In addition to being used in the Winter Olympics torch, polysilazane also has wider application potential in other industrial fields
.
Cooper Chemicals and Shanghai Carbon Fiber Composite Materials Innovation Research Institute will establish a public R&D center to develop more new carbon fiber composite materials with high temperature resistance and flame retardant properties, and apply this mysterious resin to more fields
