The application of nano anti ice coating -- silicon resin

ZS-611 anti ice coating is a high-tech special functional coating products with independent intellectual property rights of Sheng Wei Hua company, is mainly composed of alternately arranged multiblock organic-inorganic interpenetrating polymer network(IPN) base material and through high activity nano surface modification anti ice additivecomposition. Suitable for all kinds of coating methods, self curing at room temperature,was formed on the surface of the protection of 30 m dry film, can prevent ice adhesion,and has corrosion resistance, abrasion resistance, aging resistance, self-cleaning and other complex functions, can be used in aircraft, ships, power line, electric line anti icestructure.

The bond properties of 2-1 ice

The ice is one of the few can stick in the majority of most of the known material includes a polymer material, wherein the polymer comprises silicon resin, fluorocarbon resin,polyurethane resin, polytetrafluoroethylene (known as: Teflon polymer PTFE).

2-4 anti ice coating

The adhesion of the coatings on the ice is not very good, can reduce or eliminate the need for traditional anti icing, and excellent corrosion resistance.

The ice is one of the few material adhesion in most known in a polymer, a method of preventing ice adhesion in these materials, which provides a fluid interface or thin layer interface in the ice on the surface, there can not be adhered to. The material on the surface of the fluid interface or thin layer interface and ice adhesion is less than 0.2Mpa.

3-1.

Using IPN technology, by alternating copolymers composed of organic polymer modified by inorganic polymer, adhesion, hardness and other mechanical properties of the coatingare improved. At the same time, the surface of coating has low surface energy. Addspecial surfactant and nano rare earth oxide, through the interaction of components andsynergistic effect, so that the coating has low surface energy, high corrosion resistance,adhesion between the substrate and the drag reduction performance, anti wax.

The principle of 3-2

Research shows that, the surface is not only affected by the freezing phenomenon is an important factor that the ice surface temperature, surface characteristics, especially thesurface energy, surface of ice adhesion and hydrophobic surface has great influence onicing phenomenon.

Ice crystals in the adsorption force, to adhere to the ice surface, and the adsorptioncapacity of sediments, depending on the size of the ice and ice surface wettabilitybetween the surface, if the surface hydrophobic with low surface energy, it can bebetween ice and surface in wet state, can greatly reduce the adsorption capacity of ice in order to prevent freezing.

The experiment results also show that, in order to reduce the surface of the water, to prevent freezing of water surface, contact angle greater than 90 DEG, surface energymust be less than 25x10-3N/m.

Anti ice coating on solid surface, after the formation of hydrophobic layer, a thin layer ofspecial orientation on the surface of materials need to be protected, the equivalent of theprotected surface and ice layer between a separation membrane (even if the protectedsurface modification), given the characteristics of the surface:
