Abstract

The invention relates to fluorinated polyurethane nanometer composite material and a preparation method thereof. The invention combines a polycondensation co-polymerization process and fluorine-introducing ultrasonic dispersion technology in the preparation process, nanometer aluminum oxide and nanometer silicon carbide are added and compounded in homogeneous phase in the polycondensation and the co-polymerization process, thereby obtaining nanometer particle reinforced fluorinated polyurethane nanometer composite material. A coating material with micron / nanometer dual structure surface and having hydro-oleophobic, wear resistant and erosion resistant functions, is obtained after film forming by spray coating on the base, drying and curing. The coating material prepared by the method has Hydro-oleophobic performance, and satisfies heat resisting, anticorrosion and wear resistant characteristics under hypergravity or high speed impact conditions.

Description

technical field

[0001] The invention relates to a fluorinated polyurethane hydrophobic, oleophobic and abrasion-resistant coating composite material reinforced by inorganic nanoparticles and its preparation technology. In particular, the coating material prepared by the method has both hydrophobic and oleophobic properties, and has the ability to meet the requirements of ultra-thin coatings. Heat resistance, corrosion resistance, wear resistance and other properties under the conditions of gravity or high-speed impact, especially suitable for the surface treatment of metal packing in supergravity reactors and mechanical, petroleum, and chemical pipeline systems that are resistant to impact, wear, and corrosion. technical background

[0002] Since the British Imperial Chemical Industries (ICI) successfully developed the high-intensity gas-liquid mass transfer equipment Higee (High-Gravity-Rotary Device) in 1983, the research and development of high-gravity technology has attra...
