Embodiment 1

[0020] The invention provides a kind of water-based epoxy anti-flash rust paint, which takes the following components by weight:

[0021] Water-based epoxy emulsion 99g,

[0022] Water-based curing agent 33g,

[0023] 45g of antiseptic pigments and fillers,

[0024] Anti-flash rust agent 2g,

[0025] Defoamer 0.1g,

[0026] Dispersant 0.1g,

[0027] Wetting agent 0.1g,

[0028] Wax powder 1g, mix the above components and stir evenly to get water-based epoxy anti-flash rust paint.

[0029] Further, the structural formula of described waterborne epoxy curing agent is as follows:

[0030] or Alternatively, R is polyethylene polyamine, m-phenylenediamine or m-xylylenediamine.

[0031] Further, the water-based epoxy emulsion is composed of bisphenol A epoxy resin, emulsifier, water, and surfactant, and the mass ratio of bisphenol A epoxy resin, emulsifier, water, and surfactant is 10 :1:10:1.

[0032] Further, the anti-corrosion filler is one or more of zinc powder, ...

Abstract

The invention relates to waterborne epoxy flash-rust preventing paint which is prepared from 30% to 33% of waterborne epoxy emulsion, 10% to 11% of waterborne epoxy curing agent, 40% to 46% of anti-corrosive filler, 1% to 2% of flash-rust preventing agent, 1% to 2% of dispersing agent, 1% to 2% of wetting agent, 1% to 2% of defoaming agent and the balance of water in percentage by mass. According to the waterborne epoxy flash-rust preventing paint disclosed by the invention, the waterborne epoxy emulsion and the waterborne epoxy curing agent which are modified by pure plant cardanol are utilized, so that a prepared paint film is high in film hardness, good in adhesive force, excellent in anti-corrosive performance and mechanical performance, safe and environment-friendly and has no pollution. According to the waterborne epoxy flash-rust preventing paint disclosed by the invention, the paint film is better in flash-rust prevention ability and wider in construction environment, and can resist to low-temperature curing.

Description

technical field [0001] The invention relates to chemistry, in particular to coatings, in particular to a water-based epoxy anti-flash rust paint. Background technique [0002] Jiangsu University of Science and Technology applied for the patent of "A Waterborne Epoxy Anticorrosion Coating Containing Anti-Flash Rust Agent and Its Preparation Method", which uses water-based epoxy resin, water-based curing agent, anti-flash rust and other pigments and fillers as the main raw materials. After mixing and stirring at a certain percentage ratio, the required anti-flash rust coating is formed, in which the water-based curing agent is its specific alkylphenol structure. The coating prepared by this formula has strong anti-flash rust, high temperature resistance, acid resistance, alkali resistance, and organic solvent resistance. At the same time, it is convenient in construction, simple in preparation, and pollution-free. It is an environmentally friendly water-based anti-corrosion co...
