Abstract

The invention discloses a lamellar ordered hybrid coating film. The lamellar ordered hybrid coating film with thickness ranging from 500 nm to 40 mum is formed by alternately piling inorganic nano-particle layers with thicknesses ranging from 10 nm to 200 nm and polymer layers with thicknesses ranging from 50 nm to 5 mum; each inorganic nano-particle layer adopts a montmorillonite layer or hydrotalcite layer; the polymer layer is prepared by a polymer emulsion coating film; and the polymer emulsion is prepared by adopting the following method: adding a monomer, surface-active agent and initiating agent into deionized water to carry out polymerization reaction for 5 to 8 hours under the temperature of 50 DEG C to 80 DEG C, then cooling to room temperature after completion of reaction, and then obtaining the polymer emulsion. The lamellar ordered hybrid coating film material is prepared by adopting the alternately spincoating or spraying method, the thicknesses of the polymer layers and the norganic nano-particle layers can be controlled through the process; and in addition, the surface-active agent capable of taking part in polymerization is selected, and the chemical binding between inorganic platy particles and polymer phase can be realized, so that the mechanical property, the heat resistance, the corrosion resistance and other properties of the material are enhanced.

Description

(1) Technical field [0001] The invention relates to a layered ordered hybrid coating film and a preparation method thereof, in particular to a layered ordered hybrid coating film formed by alternate stacking of polymer / inorganic nano particle layers and a preparation method thereof. (2) Background technology [0002] With the continuous improvement of people's requirements for material protection in production and life, many traditional polymer coating materials can no longer meet the requirements. Therefore, the development of high-performance, wear-resistant, and corrosion-resistant organic-inorganic hybrid coating materials has become a hot spot in coating research and industry. Organic-inorganic hybrid coating materials refer to multi-phase materials in which inorganic nanoparticles are uniformly dispersed at the nanometer level in polymer coating films, and have both the performance advantages of organic materials and inorganic materials. Since the size of the inorgani...
