Abstract

The invention provides a single liquid oil and method for fabricating the same, and method for forming a thin film. The single liquid oil includes: 60-80 parts by weight of an waterborne acrylic resin; 3-10 parts by weight of a metal pigment; 0.5-3 parts by weight of an auxiliary agent; 5-12 parts by weight of an organic solvent; and 15-25 parts by weight of water.

First claim

What is claimed is:

1. An electrically conductive single liquid oil, comprising 60-80 parts by weight of an waterborne resin; 3-10 parts by weight of a metal pigment; 0.5-3 parts by weight of an auxiliary agent; 5-12 parts by weight of an organic solvent, wherein the organic solvent has a boiling point of 210° C.-250° C.; and 15-25 parts by weight of water, wherein said oil is electrically conductive and capable of forming a film having a conductivity of less than 200 mV.

2. An electrically conductive single liquid oil as claimed in claim 1 , wherein the waterborne resin comprises an waterborne acrylic resin or waterborne polyureane resin.

3. An electrically conductive single liquid oil as claimed in claim 1 , wherein the waterborne resin has an average molecular weight of 100,000-250,000.

4. An electrically conductive single liquid oil as claimed in claim 1 , wherein the metal pigment comprises aluminum pigment or copper pigment.

5. An electrically conductive single liquid oil as claimed in claim 1 , wherein the particle size of the metal pigment is about 9-15 μm.

6. An electrically conductive single liquid oil as claimed in claim 1 , wherein the auxiliary agent comprises a slip and leveling agent, defoamer, dispersant, or tackifying agent.

7. An electrically conductive single liquid oil as claimed in claim 1 , wherein the organic solvent comprises butyl glycol, butyl diethylene glycol, ethylene glycol monobutylether, dipropylene glycol butyl ether, propylene glycol phenyl ether or 2,2-4-trimethyl-1,3-pentanediol monoisobutyrate.

8. A method for fabricating an electrically conductive single liquid oil, comprising: (a) mixing and stirring a metal pigment, an organic solvent and water together to form a first mixture; (b) mixing and stirring an waterborne resin and an auxiliary agent together to form a second mixture; and (c) adding the first mixture into the second mixture to form the electrically conductive single liquid oil as set forth in claim 1 .

9. The method for fabricating the electrically conductive single liquid oil as claimed in claim 8 , wherein a stirring rate of step (a) is lower than that of step (b).

10. The method for fabricating the electrically conductive single liquid oil as claimed in claim 8 , wherein the steps (a)-(c) are conducted at room temperature.

11. A method for forming a thin film, comprising: providing an electrically conductive single liquid oil as set forth in claim 1 , wherein the single liquid oil comprises: 60-80 parts by weight of an waterborne resin; 3-10 parts by weight of a metal pigment; 0.5-3 parts by weight of an auxiliary agent; 5-12 parts by weight of an organic solvent, wherein the organic solvent has a boiling point of 210° C.-250° C.; and 15-25 parts by weight of water, wherein said oil is electrically conductive and capable of forming a film having a conductivity of less than 200 mV; printing the single liquid oil on an article; and baking the article to form a thin film on the article.

12. The method for forming the thin film as claimed in claim 11 , wherein the thin film has an electrical conductivity of 30-200 mV.

13. The method for forming the thin film as claimed in claim 11 , wherein the article comprises a plastic shell of electronic products.

14. The electrically conductive single liquid oil as claimed in claim 1 , wherein the organic solvent is butyl diethylene glycol.

15. The electrically conductive single liquid oil as claimed in claim 1 , wherein the metal pigment is a silver paste.
