Abstract

The present invention discloses one kind of composition for chemical copper plating onto timber surface and the chemical copper plating process. The composition contains copper compound, complexing agent and reductant. The chemical copper plating process is to set the timber in the composition solution, so that copper ion is reduced through chemical reaction and deposited homogeneously onto the surface of the timber and the timber surface possesses metal decoration effect and conducting performance. The present invention can reach copper coating thickness over 3.5 microns and square resistivity as low as 0.06 ohm, being comparable with copper foil.

Description

【Technical field】 [0001] The invention relates to an electroless copper plating composition and an electroless copper plating method using the composition. More specifically, the present invention relates to a composition for electroless copper plating on wood surfaces, and a method for electroless copper plating on wood surfaces using the composition. 【Background technique】 [0002] Wood is widely used in every link of national economic development, from people's daily living utensils, furniture, interior decoration and furnishing components to packaging supplies, transportation tools, sports equipment to large buildings, wood plays an important role. The use of wood has witnessed the development of human civilization. [0003] Wooden products for interior furnishings have changed from traditional full functionality to a combination of function and art, so the surface decoration of wood is particularly important. Traditional wood surface decoration is mainly covered by un...
