The nano anticorrosive thermal insulation board uses new production technology and energy conservation and environmental protection production concept. With high strength special steel plate and aluminum plate as the base material, laminated composite acid and alkali resistant corrosion resistant alloy aluminum foil, anti-aging modified polyester and fluorocarbon coating material are realized, and simultaneously achieve durable corrosion protection and high effective insulation. Compared with the color coated steel tile products commonly used on the factory roof, the service life of the nano anti-corrosion heat insulation board is more than 2-3 times of the common color coated steel tile products, and has high-efficiency heat insulation function. It has won the national invention patent, and is a new type of energy-saving and emission reduction low-carbon environmental protection material vigorously supported by the state.
