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.

Patent, is with aqueous epoxy resins, waterborne curing agent, anti-flash rusting and other color stuffings as primary raw material, with certain percentage
After proportioning is mixed, the anti-flash rusting coating required for being formed, wherein waterborne curing agent are its specific alkyl phenol structure.Pass through
Coating prepared by the formula has stronger anti-flash rusting and high temperature resistant, acidproof, alkaline-resisting, organic solvent-resistant ability, while construction
It is convenient, prepare simple, pollution-free, be a kind of water-based anticorrosive paint of environment-friendly type.
Northwest Yongxin Paint ＆ Coatings Co., Ltd. applies《Aqueous antirust paint and preparation method thereof》Patent, be mainly with aqueous
Acrylic modified epoxy resin, nertralizer, aqueous anti-flash rusting agent and anticorrosive pigment/filler are primary raw material, are matched somebody with somebody with certain percentage
Anti- flash rusting coating after mixing, required for being formed.The aqueous antirust paint hardness of film is high, and adhesive force is good, anticorrosive property
Energy and mechanical performance are excellent, and the addition of aqueous anti-flash rusting agent improves the flash rusting inhibition of paint film.The aqueous antirust paint is with water
Diluent, greatly reduces the discharge of VOC in production and work progress, safe and environment-friendly, can be widely used in steel construction, pipe
The application of the aspects such as road, auto parts and components.
The content of the invention
It is an object of the invention to provide a kind of anti-flash rusting paint of water-base epoxy, the anti-flash rusting paint of described this water-base epoxy will
Solve anti-flash rusting in prior art and paint the not good technical problem of this high and low temperature performance.
