Problems solved by technology

However, especially when it is desired to form a high-white pearlescent pattern multi-layer coating film with a whiteness L value based on the CIE equicolor function of 90 or more, the above-mentioned conductive primer is still insufficient, and such a high whiteness conductive primer base, requires the use of expensive white-based conductive pigments

Embodiment 1

[0057] According to the conventional method, 30 parts of metallocene polyethylene (weight average molecular weight is about 70,000, molecular weight distribution index 3.0), 15 parts of 1,2-dimethylimidazolium tetrafluoroborate, 15 parts of polyacrylic acid resin, quaternary ammonium 2 parts of salt conductive agent, 5 parts of melamine resin, and 20 parts of red iron oxide were diluted with deionized water so that the solid content became 44%, thereby obtaining a conductive coating composition.

Embodiment 2

[0059]According to conventional methods, 40 parts of metallocene polypropylene (weight-average molecular weight of about 120,000, molecular weight distribution index of 1.5), 30 parts of 1-butyl-3-methylimidazolium hexafluorophosphate, 10 parts of polyacrylic acid resin, quaternary 1 part of ammonium salt conductive agent, 10 parts of hexamethylene diisocyanate, and 20 parts of red iron oxide were diluted with deionized water so that the solid content became 42%, thereby obtaining a conductive coating composition.

Embodiment 3

[0061] According to the conventional method, 60 parts of metallocene polypropylene (weight average molecular weight is about 100,000, molecular weight distribution index 2.0), 1 part of 1-hexyl-3-methylimidazolium tetrafluoroborate, 30 parts of polyacrylic acid resin, quaternary 5 parts of ammonium salt conductive agent, 25 parts of hexamethylene diisocyanate, and 5 parts of red iron oxide were diluted with deionized water so that the solid content became 42%, thereby obtaining a conductive coating composition.

Abstract

The invention relates to a paint composition. The composition contains metallocene polyolefin and ionic liquid. The metallocene polyolefin is selected from one or a mixture of at least two of metallocene polyethylene, metallocene polypropylene, metallocene low-density polyethylene and metallocene linear low-density polyethylene. According to the paint composition provided by the invention, the ionic liquid and the metallocene polyolefin are mixed to obtain the paint composition which can be used for forming a conductive under-painting coating film with high luminance color, high covering power and sufficient conductivity even if an expensive white series conductive pigment is not used and when only a common white pigment is matched.

Description

technical field [0001] The present invention relates to a coating composition and its application, in particular to a coating method using the composition and to the resulting coated article, in particular, the present invention relates to a paint with sufficient electrical conductivity even without the use of conductive pigments. A coating composition for a permanent coating film, a coating method thereof, and a coated article. Background technique [0002] Plastic materials used in automotive shock absorbers, etc., usually have about 10 10 With a volume resistivity of Ω·cm or higher, it is difficult to directly coat such a plastic molded product with an electrostatic coating method that is excellent in coating efficiency. Therefore, in the prior art, a conductive primer is first applied to such a material surface, and then a surface paint for coloring is electrostatically applied (for example, refer to JP-A-6-165966). [0003] In addition, plastic materials used for auto...
