Embodiment 1

[0027] An oil-resistant, high-efficiency and anti-corrosion water-based epoxy zinc-rich primer, which is used to replace the solvent-based coating of the heat dissipation oil tank of the transformer box, includes the following components in parts by weight: water-based epoxy resin 132, environmental protection co-solvent 10, phosphorus iron powder 50 , Zinc powder 740, dispersant 5, defoamer 1, anti-flash rust additive 2, curing agent 60.

[0028] Wherein: the water-based epoxy resin is a low-molecular-weight high-functionality reactive epoxy resin with a molecular weight of 2000-5000, which is a water-based low-molecular-weight high-functionality reactive epoxy resin that can be rapidly cross-linked and polymerized at room temperature to form a dense network The structure and the interaction between molecules make the solvent unable to penetrate effectively, so that it can be used for a long time in a high temperature and high oil environment without dissolution and shedding. ...

Abstract

Oil-proof highly-anticorrosion waterborne epoxy zinc-rich primer is disclosed. The primer is used for replacing solvent based coating for a heat dissipation oil tank of a power transformation box. Theprimer includes, by weight, 130-190 parts of waterborne resin, 20-60 parts of an environmentally friendly cosolvent, 5-10 parts of ferrophosphorus powder, 700-750 parts of zinc powder, 5-10 parts ofa dispersant, 1-2 parts of a defoamer, 2-3 parts of an auxiliary agent preventing flash rust and 60-80 parts of a curing agent. The objective of the invention is to provide the oil-proof highly-anticorrosion waterborne epoxy zinc-rich primer for replacing the solvent based coating for a heat dissipation oil tank of a power transformation box. The cost is reduced, the dosage of solvents is greatlyreduced, the primer is free of heavy metal and is more beneficial to human body health, and indexes of the primer in aspects of salt mist resistance, adhesive force, hardness, waterproofness, solventresistance, and the like can reach those of the solvent based coating.

Description

technical field [0001] The invention belongs to the technical field of industrial water-based coatings, in particular to an oil-resistant, highly efficient and anti-corrosion water-based epoxy zinc-rich primer. Background technique [0002] With the continuous and rapid development of China's economy over the years, China has become the second largest economy in the world, but it has also brought its huge energy demand. The huge power transmission facilities need long-term anti-corrosion protection, which has generated huge market demand. Transformer is an important equipment for long-distance power transmission, and the inner wall of its oil tank needs to be coated with oil-resistant, efficient and anti-corrosion coating. [0003] Only the painting of fuel tanks has formed a huge market. In recent years, the production capacity has gradually increased, and it has only rebounded in the recent market downturn. However, with the continuous advancement of China's strategy, the ...
