Project Cooperation of Key Laboratory of Marine New Materials and Applied Technology of Chinese Academy of Sciences: Low-temperature Anti-icing and Easy-Deicing Coating Project

01 Project background

With the evolution of global warming, polar sea ice continues to melt, and the development and utilization of polar waterways is gradually turning from ideal to reality, and this process trend is accelerating.
With the growth of my country's strength, the rights and interests of the two poles will be more and more important, but ice-breaking ships need to be coated with special ice-breaking paint for navigation in ice areas, and my country's research and development of ice-breaking paint is basically blank.
The development of a coating system with long life, low energy consumption, impact resistance, high weather resistance and anti-icing performance will greatly improve the high-performance service life of China's polar ships and offshore platforms, and solve the development of bases in China's polar ultra-low temperature environment.
and the safe use of bottlenecks and ensure long-term security service of polar expedition, shipping and resource extraction of critical infrastructure equipment is of great strategic significance com" href="http://">paint online coatingol.

In the field of power grids, icing and snow on transmission lines threaten the safe operation of power and communication networks.
Under certain climatic conditions, icing and disconnection of power lines caused by freezing weather have occurred from time to time.

In order to solve the above problems, the timely development of corresponding long-term anti-icing technology has become an important and urgent issue.

This project intends to design and manufacture adaptive materials for extreme low temperature environments from the perspective of chemical modification, develop a coating system that integrates anti-icing and low temperature toughness, and is optimized for different sea areas, different alternating environments, and different service cycles.
The structure and performance of the material under working conditions ensure that the surface protective coating of the material has the integrated long-term protection characteristics of high toughness, impact resistance, corrosion resistance and anti-icing, so as to realize the protection of polar sailing ships and offshore platforms and power grids and other facilities.

02 Technical features

Technical route: From the perspective of molecular structure design, hybrid technologies such as hyperbranched and interpenetrating networks are used to enhance the toughness of resins and curing agents while maintaining high hardness and high weather resistance, solving the problem of low-temperature brittleness of the coating, and at the same time in the side chain Introducing low surface energy groups such as fluorine and silicon, and solving the problems of long-term anti-icing and easy deicing of the coating through two-component cross-linking and curing.
Realize the integrated synergy of resin and curing agent low temperature toughness and anti-icing and easy deicing.

The anti-icing coating developed is smooth, has a large elevation angle, good elasticity, reduces contact friction, has high coating adhesion, and has good adhesion to ice-coated substrates.
At the same time, the coating surface exhibits very low surface energy.

The product has been trial-produced in the laboratory and is undergoing pilot scale-up production.
The production process is basically the same as that of ordinary anti-corrosion coating products, without additional equipment or production lines.

03 Market situation

With global warming, the polar environment not only has high strategic significance, but also has broad market prospects.
At present, domestic related products are still blank.

The anti-icing and easy-to-deicing coatings for power grids have universal applicability under low-temperature "freezing rain" environments in winter, and can essentially improve the operational safety of power grids, with a potential market capacity of several billion yuan.

The demand for anti-graffiti in urban construction environment is even more universal.

Based on the above characteristics, this series of products start from the level of molecular structure design and independent synthesis of key materials, and realize the high-quality independent controllability of the materials, and the commercialization cost is equivalent to the existing products in the market, which greatly improves the cost-effectiveness of the products.
Very good economic and social benefits.
