Water-based environment-friendly negative ion anticorrosive paint and preparation method thereof

Abstract

The invention discloses water-based environment-friendly negative ion anticorrosive paint and a preparation method thereof. The paint is prepared from, by weight, 20-40% of water-based epoxy resin emulsion, 10-20% of water-based polyurethane emulsion, 5-10% of water-based fluororesin emulsion, 10-15% of water-based nanometer negative ion sizing, 1-3% of water-based wetting dispersant, 0.1-1% of a water-based antifoaming agent, 1-3% of an adhesion promoter, 5-10% of lead-free anti-rust pigment, 0.5-2.5% of an anti-fouling agent, 5-10% of a coalescing agent and 5-25% of deionized water. The paint can be smeared to the surfaces of base material members like steel to form effective corrosion protection, decorative performance is high, energy consumption is low, negative ions are released, and the service life is long; the paint can be widely applied to the fields of hardware steel members, engineering machines, locomotive ships, road bridges, tunnels, sewage treatment, industrial terrace and the like, the base material can be effectively protected with high closure, corrosion prevention, wear and scrape resistance, acid and base resistance and impact resistance, negative ions beneficial to surrounding are generated, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of water-based environment-friendly anti-corrosion materials, in particular to a water-based environment-friendly negative ion anti-corrosion coating and a preparation method thereof. Background technique [0002] Due to the characteristics of light weight and good ductility, steel structure materials have become the most important structural form of large space buildings. Steel has the characteristics of earthquake resistance and bending resistance, but its mechanical properties will decrease rapidly under the influence of outdoor climate, diurnal temperature difference, etc. With the rapid development of steel structure buildings, the technical problems of steel structure anticorrosion protection become more prominent, so it is necessary to The steel structure is protected against corrosion to prevent the mechanical properties of the steel structure, such as yield point, tensile strength and modulus of ela...

Problems solved by technology

[0004] At present, traditional solvent-based anti-corrosion coatings also have some disadvantages, such as containing a large amount of solvents, VOC and other toxic volatile substances, which cause serious environmental pollution due to volatilization during the construction process, and the cost is high. It is not ideal, which leads to the corrosion resistance of steel structures that are difficult to protect for a long time in the long-term outdoor harsh process. A large number of metals need to be smelted, equipment and components need to be replaced, resulting in a serious waste of resources and energy, and even cause disasters and accidents, resulting in direct economic losses, etc.
