Problems solved by technology

[0003] 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-white conductive primer base, requires the use of expensive white-based conductive pigments

Embodiment 1

[0041] According to the conventional method, 30 parts of metallocene polyethylene (weight average molecular weight is about 60,000, 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

[0043] According to conventional methods, 40 parts of metallocene polypropylene (weight-average molecular weight of about 140,000, 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

[0045] 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 coating composition. The coating composition comprises metallocene polyolefin and ionic liquid, wherein 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; the ionic liquid is fused salt. The ionic liquid and the metallocene polyolefin are selected and mixed so as to obtain the coating composition, wherein the coating composition with a conductive bottoming coating film and with high brightness color, high covering power and a sufficient conductive property only by matching with general white pigment even without using expensive white conductive pigment.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating composition. 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 top paint for coloring is electrostatically applied. In addition, plastic materials used for automobile shock absorbers usually have a dark color such as black. When painting a light-colored or low-hiding finish paint, it is required to have a high hiding power or a high Brightness color. In order to meet such demands, various conductive paints using conductive pigments with relatively high brightness have conventionally been proposed. However, the antim...
