Problems solved by technology

At present, most of the electrostatically conductive coatings for oil reserves that are widely used on the market use conductive fillers such as metals, carbon-based materials, or metal oxides as conductive media. Due to the large amount of fillers, the anti-corrosion and electrical conductivity of the coatings cannot be balanced. , there are shortcomings such as polluting oil, poor corrosion resistance and adhesion, and short service life

Embodiment 1

[0030] 1. Preparation of color paste:

[0031] Weigh 367g of water, then add 9g of dispersant (SF-03), 4g of wetting agent (BYK-181), 1g of hydroxyethyl cellulose, 1g of defoamer (BYK-025), 1g of fungicide (981), pH adjuster (AMP-95) 2g, antifreeze agent ethylene glycol 20g, film-forming aid A (dodecyl alcohol ester) 25g, stir for about 15min to form a uniformly dispersed system; then add iron oxide red 100g, mica Powder (800 mesh) 40g, talc powder (1250 mesh) 50g, barium sulfate (1250 mesh) 180g, aluminum tripolyphosphate 135g, zinc phosphate 45g, high-speed stirring and grinding (2500 rpm) 1.5h, fineness ≤ 45μm .

[0032] 2. Preparation of film-forming agent:

[0033] Take 1000g of the above slurry, add 800g of acrylate grafted epoxy resin emulsion, 4.5g of anti-flash rust agent, 2g of thickener B (polyurethane associative thickener), 3.6g of polyurethane rheological thickener, and form a film Auxiliary ethylene glycol monobutyl ether 24g, stir evenly to obtain film-formi...

Embodiment 2

[0042] 1. Purification of carbon nanotubes: use 5% HF and 5% HNO to 2 g carbon nanotubes 3 Washing is performed to remove impurities from the carbon nanotubes, followed by a deionized water wash to remove residual acid.

[0043] figure 1 is the scanning electron micrograph of unpurified carbon nanotubes, figure 2 SEM images of purified carbon nanotubes. Compared figure 1 , 2 , it can be seen that impurities on the surface of carbon nanotubes are significantly reduced after treatment, indicating that carbon nanotubes are purified, which is conducive to improving the antistatic performance of the matrix material.

[0044] image 3 Among them, curve a is the infrared spectrum of carbon nanotubes without purification treatment, and curve b is the infrared spectrum of carbon nanotubes after purification treatment. The contrast between the two curves can be seen: at 1495cm -1The stretching vibration peak of the hydroxyl group is obviously enhanced, indicating that the carbox...

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to the technical field of water-based antistatic anticorrosion paint. Background technique [0002] In recent years, my country's petroleum and petrochemical industry has developed rapidly, and metal storage tanks for petroleum and petrochemical use have also increased. Therefore, the protective coating of oil storage tanks has also received increasing attention and attention. The static electricity and corrosion generated on the inner wall of the oil storage tank will seriously endanger the quality and safety of oil storage, so the tank must be protected. At present, most of the electrostatically conductive coatings for oil reserves that are widely used on the market use conductive fillers such as metals, carbon-based materials, or metal oxides as conductive media. Due to the large amount of fillers, the anti-corrosion and electrical conductivity of the coatings cannot be ...
