Abstract

A method of surface treatment includes a step of positioning objects on branches and coating a base film on the objects, a step of electro-plating a metal layer on the objects by way of vacuum electroplating, and step of dipping the objects into acrylic electro-coating liquid to coat an anti-rusting acrylic layer on the objects.

Description

    FIELD OF THE INVENTION
  • The present invention relates to a method of a surface treatment for electro-plating a metal layer on a metal or a nonmetal surface and a non-corrosive acrylic layer is coated on the metal layer.
    • BACKGROUND OF THE INVENTION
  • A conventional method for electro-plating a metal layer to an object such as handles of drawers, door handles and locks generally uses a strong acid solution to remove foreign particles and dust from the surface to be treated and the object is put in an electrolytic tank to electro-plate a desired metal layer on the surface of the object. A lacquer is coated on the metal layer to be a protection layer. However, it is noted that the chemical solution such as the strong acid solution is harmful to the environment and the treatment equipment to deal with the chemical solution is expensive and thereby increasing the manufacturing cost. Besides, only that the objects have metal surface can be electro-plated and this restricts the range of use. In addition, the lacquer does not have good anti-corrosive function which is important in some circumstances. The lacquer also lacks durability and the luster is difficult to be maintained. Usually, the object is coated with copper, nickel and silver to have an anti-rusting function, nevertheless, the multiple processes increase manufacturing cost too.
  • The present invention intends to provide a method of surface treatment for metal or nonmetal surfaces and the method is less expensive, and makes the surfaces to be luster and anti-rusting.
    • SUMMARY OF THE INVENTION
  • The present invention relates to a method of surface treatment and the method includes the following steps:
  • step of positioning objects on branches and coating a base film on the objects; step of electroplating a metal layer on the objects by way of vacuum electroplating, and step of dipping the objects into electro-coating liquid to coat an anti-rusting layer on the objects.
  • The primary object of the present invention is to provide a method for generating an anti-rusting and shining surface on metal or nonmetal surfaces.
  • Another object of the present invention is to provide a method of surface treatment and the method reduces pollution to the environment and is less expensive.
  • The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 shows steps of the method of the present invention;
  • FIG. 2 shows the objects to be positioned on the braches;
  • FIG. 3 is an enlarged view to show the objects on the branches;
  • FIG. 4 shows the objects on the branches are put in an electro-plating tank;
  • FIG. 5 shows that the objects on the branches are dipped into electro-coating liquid, and
  • FIG. 6 shows a cross sectional view of the object after the surface treatment.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1 to 6, the method of surface treatment of the present invention comprises the following steps:
  • step of objects positioning: positioning objects 20 on branches 12 and coating a base film 50 on the objects 20;
  • The branches 12 extend radially from a post 10 which includes top and bottom connection members 11. Each branch 12 is connected with an object 20 as show in FIG. 3. The base film 50 allows metal particles to be easily attached thereon.
  • step of roasting: putting the objects 20 together with the post 10 and the branches 12 in to an oven to dry and solidify the base film 50.
  • step of electro-plating: electro-plating a metal layer on the objects 20 by way of vacuum electro-plating;
  • As shown in FIG. 4, after the base film 50 is dried and solidified, the objects 20 together with the post 10 and the branches 12 are moved to a vacuum electro-plating furnace 30. A positioning disk 31 is located in the furnace 30 so that the post 10 are positioned on the positioning disk 31. A power unit 300 is located in the furnace and includes two electro poles 32 between which a tungsten filament 33 is connected 33. The tungsten filament 33 is wrapped by metal 34 to be electro-plated. The air in the furnace 30 is sucked out to form a vacuum furnace and when the electro poles 32 are powered by electric power, the tungsten filament 33 is heated so as to let the metal 34 to be electro-plated become particles which are attached to the base film 50 to form an electro-plating layer 51.
  • step of electro-coating: dipping the objects 20 into electro-coating liquid to coat an anti-rusting layer on the objects 20.
  • As shown in FIG. 5, the objects 20 together with the post 10 and the branches 12 are moved to the electro-coating stand and dipped into an electro-coating liquid 41 in a tank 40 and the electro-coating liquid 41 is an acrylic liquid 41 with ions. The objects 20 and the post 10 are electric conductive so that the electro-coating liquid 41 is attached to the surface of the objects 20 to form an anti-rusting acrylic film 52.
  • step of roasting: putting the objects 20 together with the post 10 and the branches 12 in to an oven to dry and solidify the anti-rusting acrylic film 52.
  • step of removing objects from branches.
  • The objects 20 are removed from the branches 12 when all the steps are completed.
  • The base film 50 fills all the tiny dimples on the surface of the objects 20 so that the electro-plating layer 51 can be electro-plated thereon. No chemical solution is needed in this step so that the pollution to the environment can be effectively reduced.
  • Due to the base film 50, the method can electro plate a layer of metal on metal or nonmetal surfaces. The electro-plating layer 51 is in contact with the post 10 so that the objects 20 do no need to remove from the branches 12 and are dipped into the acrylic electro-coating liquid 41 for form the anti-rusting acrylic film 52 which is stiff, durable and can maintain the luster.
  • While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
