Composite material using nano inorganic powder as surface with autocatalytic activity and preparation method thereof

Abstract

The invention discloses a compound material which takes nano inorganic power as an autocatalysis active surface as well as a preparation method thereof, and belongs to the field of compound material. The invention is characterized in that a nano inorganic power layer is used as the bedded compound material of the autocatalysis active surface; fiber, plastic, fabric, resin, glass, ceramics, monocrystal line silicon and metals are used as the material of a substrate; the nano inorganic power like nano titanium dioxide or nano magnesia or nano zinc oxide or nano alumina, or nano zirconia, or nano nickel oxide, or nano jewellers putty, or nano cobalt oxide is used as an autocatalysis active material; an layer of nano inorganic power film is coated on the surface of the substrate material by adopting a dipping coating method and is used as the autocatalysis active surface; then a chemical method is adopted to load metals on the autocatalysis active surface of the nano inorganic power to develop the bedded compound material which has high quality and low cost, and takes the nano inorganic power as the autocatalysis active surface. The nano inorganic power is used as the autocatalysis active surface to replace the heavy metals of platinum, palladium and sliver in the traditional chemical plating, thus saving the heavy metals, reducing the product cost, shortening the technique flow and reducing the environment pollution.

Problems solved by technology

However, the commonly used catalysts in this process are precious metals such as platinum, palladium, silver, etc. Not only the waste of precious metals is serious, but also the whole process equipment is complicated, the process is complicated, and the operation technology is difficult, resulting in high product cost; various pretreatment liquids are unstable. , The composition is not easy to control, the pass rate of large-area plating is low, and the product quality is difficult to meet the requirements; in addition, the use of a large number of chemical reagents also makes the production process more polluted, which is increasingly not in line with the requirements of economic and social development
