Technical field
The present invention relates to a kind of nano-silver thread conductive resin and electro-plating method, belong to field of new.
Background technology
Plating utilizes chemistry and electrochemical method to plate various metal at metal or at other material surface.Electroplating technology is widely used in the industries such as manufacture, light industry, electronics.Plastic electroplating can make surface of plastic products have metalluster, attractive in appearance, plays decoration function; Improve the physical strength of product surface, increase the service life; Plastics are made to have higher stability to the extraneous factor such as light and air, not easily aging; Plastics are made to have conduction, magnetic conduction and weldability.Plastic electroplating goods can be used for the industries such as aerospace, shipbuilding, automobile, electronic apparatus, building decoration, toy and daily necessities, and purposes is very extensive.The plastics that can be used for electroplating comprise: ABS, polypropylene, polysulfones, polycarbonate, nylon, polystyrene and phenolic glass fiber reinforced plastics etc., wherein maximum with ABS consumption, technique is the most ripe, and electroplating effect is best.
Conventional plastic electroplating technology flow process, its technical process is followed successively by: oil removing, alligatoring, sensitization, activation, electroless plating, plating, nickel plating, chromium plating, finished product.Five steps more than in operation before electroplating operations are chemical plating technology, from electroplating operations, are conventional plating process.
Chinese patent 201410298602.X discloses a kind of electrosilvering paint, be made up of the component of following weight percents: fine silver slurry 2-5%, celluosic resin 6-15%, acrylic resin 40-60%, melamine resin 1-3%, titanic acid ester modified additive 0.5-1%, N-BUTYL ACETATE 10-25%, pimelinketone 5-10%, toluene 5-10%.By the way, a kind of electrosilvering paint of the present invention, can make the plastic cement paint that can compare favourably with vacuum plating, solve vacuum plating and pollute the problems such as large, energy consumption is high, have and pollute the advantage little, energy consumption is low.But organic content contained inside this electrosilvering paint is very high, and there is a large amount of volatile organic solvent, cost with the pollution of environment is hindered to its industrialization and popularizes, simultaneously electroplating technology required voltage and electric current all higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of nano-silver thread conductive resin and electro-plating method.
In order to achieve the above object, technical scheme of the present invention is: a kind of nano-silver thread conductive resin, it is characterized in that, be made up of the raw material of following weight percent: nano-silver thread 0.5 ~ 1.5%, thickening material 0.5-1.5%, linking agent 5-8%, flow agent 0.05-0.1%, adhesion promoter 0.05-0.1%, surplus is solvent.
