Benefits of technology
The present invention provides a nanocomposite coating and a method for protecting products from corrosion and damage caused by external chemicals. The coating is made by mixing a nanometer inorganic oxide gel, an organic solvent, and a nanometer powder. The coating is applied to the surface of the product using spraying, dipping, or roll-to-rolling. The coated product is then exposed to room temperature or a heating environment below 170 degrees centigrade to allow the coating to dry and form nanometer protective films on the surface of the product. This coating provides effective protection against corrosion and damage caused by external chemicals.
Problems solved by technology
However, some engineering plastic materials, such as polycarbonate and modified polyphenylene oxide, are easily corroded and damaged by some exterior chemicals, such as organic alcohol, organic ketone, acid, alkali and oil etc.

Embodiment Construction
[0008]A nanocomposite coating according to the present invention is a mixture of a nanometer inorganic oxide gel, an organic solvent and a nanometer powder, wherein the weight percentage of the nanometer inorganic oxide gel, the organic solvent and the nanometer powder in the nanocomposite coating is respectively 22.5˜49.5%, 45˜74.25% and 1˜10%. The nanometer inorganic oxide gel is made by a sol-gel method and can be any one of or a mixture of at least two selected from a nanometer silicon dioxide gel, a nanometer titanium dioxide gel and a nanometer zirconium dioxide gel. The organic solvent can be any one of or a mixture of an ethanol solvent and an isopropanol solvent. The nanometer powder has a 5˜100 nm diameter and can be any one of or a mixture of a nanometer metal powder and a nanometer metal-oxide powder, wherein the nanometer metal powder can be any one of or a mixture of at least two selected from a nanometer platinum powder, a nanometer copper powder and a nanometer nicke...

Abstract
A nanocomposite coating and a method of coating for protecting a product with the nanocomposite coating are presented. Firstly, the nanocomposite coating is prepared, wherein the nanocomposite coating is formed by mixing 22.5˜49.5% nanometer inorganic oxide gel made by a sol-gel method, 45˜74.25% organic solvent and 1˜10% nanometer powder together. Next, the nanocomposite coating is coated onto surfaces of the product evenly by way of spraying, dipping or roll-to-rolling. Lastly, the product coated with the nanocomposite coating is subjected to a room temperature or a heating environment lower than 170 degrees centigrade to make the nanocomposite coating dry for forming nanometer protective films on the surfaces of the product.
Description
CROSS REFERENCE[0001]This is a divisional of U.S. application Ser. No. 12 / 276,117, filed on Nov. 21, 2008, which is incorporated herewith by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention generally relates to a coating and uses thereof, and more particularly to a nanocomposite coating and a method of coating for protecting a product with the nanocomposite coating.[0004]2. The Related Art[0005]At present, lots of products are made of engineering plastic materials. However, some engineering plastic materials, such as polycarbonate and modified polyphenylene oxide, are easily corroded and damaged by some exterior chemicals, such as organic alcohol, organic ketone, acid, alkali and oil etc. In order to protect the products made of the foregoing engineering plastic materials from being corroded and damaged, a nanocomposite coating and a method of coating for protecting the products with the nanocomposite coating are required.SUMMARY OF THE...
