Embodiment 1

[0044] Dissolve 70g of epoxy resin (E-44) in 110g of xylene, 25g of Huntsman Jeffamine D-230, 0.45g of nano-conductive zinc oxide (the doping element is aluminum, and the volume resistivity is 1.0×10 1 Ω cm), 0.015g BYK-110, 0.01g BYK-065, 0.0047g CuCl 2 (5×10 -7 mol / g) were added together to the above mixed solution, heated to 40°C and stirred at high speed for 40 minutes at a speed of 1250 rpm, then stopped stirring and cooled to room temperature to obtain a transparent conductive coating. After the coating was applied to the MDF wood board, it was cured at 70°C for 10 minutes to obtain a smooth, continuous and flat coating. The flatness of the coating is 2μm, and the volume resistivity is 6.32×10 2 Ω·cm, adhesion level 0, light transmittance 91%.

Embodiment 2

[0046] 100g of acrylic resin ( M825) was dissolved in 200g of isopropanol and toluene mixture, and then 1.05g of nano-conductive zinc oxide (doping element was gallium, volume resistivity was 3.9×10 0 Ω·cm), P104S, 0.49g FeCl 3 (3×10 -5 mol / g) were added together to the above mixture, ultrasonically dispersed for 30 minutes, heated to 50°C and stirred for 30 minutes, stopped stirring and cooled to room temperature to obtain a transparent conductive coating. After the paint is coated on the PVC board, it is dried at 60°C to obtain a smooth, continuous and flat coating. The flatness of the coating is 1μm, and the volume resistivity is 1.52×10 0 Ω·cm, adhesion level 0, light transmittance 96%.

Embodiment 3

[0048] 95g of water-based polyurethane ( A145) mixed with 150g of water, mixed with 5g of nano-conductive zinc oxide (doping element is cesium, volume resistivity is 2.5×10 -3 Ω cm), 2.5g Efka-766, 1gTEGO Airex970, 0.64g (1×10 -4 mol / g) CuCl was mixed and stirred for 50 minutes, heated to 60°C and stirred for 10 minutes, stopped stirring and cooled to room temperature and emulsified by an emulsifier for 5 minutes to obtain a transparent conductive coating. After the paint is coated on the tin plate, it is dried at 80°C to obtain a smooth, continuous and flat coating. The flatness of the coating is 3 μm, and the volume resistivity is 7.88×10 -4 Ω·cm, adhesion level 0, light transmittance 93%.

Abstract

The invention relates to a conductive coating composition. The conductive coating composition comprises the components in parts by weight: 65-100 parts of high molecular resin, 0.001-5 parts of conductive nano-zinc oxide, 110-200 parts of solvent and 0-30 parts of curing agent. The electrical resistivity of a conductive coating is 10<-4> to 10<3> omega.cm, the conductive nano-zinc oxide is light-colored, and the addition amount is small, thus the obtained conductive coating is high in transparency, and the light transmittance reaches as high as 96%.

Description

technical field [0001] The invention relates to a conductive coating composition, which belongs to the field of coatings. Background technique [0002] Conductive coatings refer to coatings that have the ability to conduct electricity and eliminate accumulated static charges, and are generally divided into intrinsic type and filling type. Intrinsic conductive coating means that the polymer material used as the conductive coating matrix itself has conductivity, mostly a compound of polyphenylene and polyacetylene, but this type of conductive polymer material has a high resistivity, poor conductivity stability and repeatability , and the cost is higher. The film-forming substance in the filled conductive coating is insulating, and in order to make the coating conductive, the common treatment method is to add conductive fillers. The most commonly used conductive fillers are metal fillers, carbon fillers and metal oxide fillers. Metal filler conductive coatings are expensive,...
