Intoduction

When a ship is anchored at a dock or a ship is anchored to a ship, the huge hull will produce a very large impact force due to collision; when a ship is anchored at a dock, due to the combined effect of the sea wind, waves and the rise and fall of the water level, the ship will collide with the dock, compress and rub against it, producing a three-dimensional force with an extremely complex mechanism and a long duration. These forces often cause damage to the quay structure and the ship. Therefore, the selection of an appropriate anti-collision buffer to absorb the kinetic energy of the collision and reduce the mutual reaction force between the ship and the quay or between the ship and the vessel is undoubtedly very important for the protection of both the quay and the ship. The globalization of the economy and logistics has promoted the development of global maritime shipping and continental maritime and land transport, making the size of maritime transport vessels ever larger.

Large ships with large tonnage, large draft, large momentum and additional water mass are also large (when the ship moves in the water, the water around the ship also moves with it, when the ship docks on the pier, this part of the water body moves with the ship and generates impact energy on the pier through the ship, the mass of this part of the water body is called additional water mass), the combined effect of the two is enormous impact energy when docking, which makes the offshore port This has placed higher design and operational demands on docks in offshore ports, making the development of dock structures towards deeper waters and larger scale an irreversible inevitable trend. In parallel with the trend towards berth development, the growth of larger ships has also created new requirements for additional berth equipment and facilities, such as the need for larger size and capacity of loading and unloading equipment to accommodate the increased scale of ships and the need for fenders that absorb more impact energy to safely moor large capacity ships.

Spray polyurea elastomer technology has many advantages.

1. Catalyst-free, highly reactive and fast curing, it can be sprayed on any inclined, curved or vertical surface without sagging.
2. It is not sensitive to humidity and temperature and is not affected by the temperature of the component or environment or the humidity of the component or air, and can be applied at temperatures from -40 to 50°C.
3. It is a two-component paint with 100% solid content, contains no volatile organic solvent (VOC), environmentally friendly, the evaporation of the solvent does not cause the construction site to be filled with the odor of the evaporated solvent, can achieve hygienic construction and non-hazardous construction.

4. The manufacturing process can be carried out by thermal spraying or cracking, and the thickness of an application can range from a few hundred um to a few cm, overcoming the shortcomings of the traditional environmentally friendly coating process, which requires several applications to achieve the designed coating thickness.
5. It has excellent physical and chemical properties, high tensile strength, elasticity and elongation at break, abrasion resistance, anti-slip properties, solvent and salt spray aging properties, resistance to seawater and general solvent corrosion. Hardness can be adjusted at will and the feel ranges from soft rubber to hard elastomer. No chalking, cracking or peeling in long-term outdoor use.

.
6. Good thermal stability and good low temperature resistance, can operate at 120°C for a long time, can withstand 350°C instantaneous thermal shock.
7. Good reproducibility of substrate shape, continuous and dense coating, no joints, no bubbles and holes, beautiful and durable. It is possible to add various pigments, short glass fibers and other fillers to make different colors and performance requirements of coating products, to meet the customer's needs for color and other performance aspects.
