preparation example Construction

[0018] The preparation method of the conductive coating composition provided by the invention comprises mixing conductive particles, a resin and a solvent, wherein the resin is an alcohol-soluble resin, and the solvent is an alcohol solvent.

[0019] The amount of the conductive particles, resin and solvent is such that in the prepared conductive coating composition, based on the total weight of the conductive coating composition, the content of the conductive particles is 2-80% by weight, preferably 5-70% by weight. % by weight, more preferably 10-60% by weight; the content of resin is 2-60% by weight, preferably 3-50% by weight, more preferably 5-40% by weight; the content of solvent is 2-70% by weight, preferably 5-60% by weight, more preferably 10-50% by weight.

[0020] The preparation method also includes adding auxiliary agents and mixing, and the types of the auxiliary agents include wetting and dispersing agents, anti-sedimentation agents, coupling agents and adhesion...

Embodiment 1

[0024] This example is used to illustrate the conductive coating composition provided by the present invention.

[0025] 15 parts by weight of B-67 resin (produced by Rohm and Haas), 5 parts by weight of organically modified bentonite anti-settling agent 818 (produced by Elementis Specialties company), 2 parts by weight of wetting and dispersing agent (DP983, Deqian produced by the company), 2 parts by weight of monoalkoxy titanate coupling agent T204 (produced by Nanjing Xiangfei Company) were mixed, and stirred at a speed of 3000 rpm for 30 minutes. Add the average particle diameter of 16 weight parts then in the mixture that is obtained and be the spherical conductive silver powder (SA-1 of Kunming Science and Technology Hengda) of 1 micron and the flake conductive silver powder (PA-1) of 10 microns of average particle diameter of 10 weight parts 1D, Kunming Polytechnic Hengda), and then add 50 parts by weight of solvent (ethanol and isopropanol with a volume ratio of 1:1),...

Embodiment 2

[0027] This example is used to illustrate the conductive coating composition provided by the present invention.

[0028] The average particle diameter of 25 parts by weight of polyvinyl butyral resin (B-79, Solutia Inc.), the average particle diameter of 50 parts by weight is the spherical conductive silver powder (Ningxia Dongfang special material) of 1 micron and the solvent of 25 parts by weight (ethanol and isopropanol with a volume ratio of 1:1) were mixed and stirred at a speed of 2000 rpm for 3.5 hours to obtain conductive coating composition D2.

Abstract

The invention discloses a conductive paint composition, which comprises the following parts: conductive particle, resin and solvent, wherein the resin is alcohol-soluble resin; the solvent is alcohol solvent. The invention also provides a making method of the conductive paint combination, which has weak corrosiveness for base, therefore not incurring base explosion.

Description

technical field [0001] The present invention relates to a conductive coating composition. Background technique [0002] With the development of information, home appliances, electronics, military and aviation technology, the hazards of electromagnetic radiation are highly valued by people. Electromagnetic radiation not only affects the health of the human body, but also interferes with the normal use of electronic equipment. How to effectively prevent the interference of electromagnetic radiation has been paid more and more attention by people. At present, the extensive use of plastic substrates with high resistivity makes it particularly important to prevent electromagnetic radiation interference. [0003] The commonly used method to prevent electromagnetic radiation is to form a conductive layer on the surface of the substrate, so that the substrate has the ability to conduct current and eliminate the accumulated static charge, thereby preventing electromagnetic radiatio...
