Description
Technical field
The present invention relates to the rust-inhibiting paint technical field, relate in particular to a kind of water-base epoxy phosphoric acid salt zinc dust anticorrosion paint and preparation method.
Background technology
Metallic substance in use owing to being subject to the impact of the environment such as atmosphere, seawater, soil, is damaged or degradation along with the prolongation of time gradually, is commonly referred to corrosion or aging.70% iron and steel as large-scale steel bridge, vehicle, boats and ships, basin, factory building etc. all is to use in the environment that easily gets rusty.
Rust-inhibiting paint is a kind of chemistry that the metallic surface avoids atmosphere, seawater etc. or coating of galvanic corrosion protected.Mainly be divided into physical property and chemically antirust paint two large classes.The former forms fine and close paint film to stop the intrusion of corrosives, such as iron oxide red, aluminium powder, graphite rust-inhibiting paint etc. by the suitable cooperation of pigment and paint vehicle; The latter presses down the rust effect by the chemistry of rust-stabilising pigment, such as red lead, zinc yellow anticorrosive paint etc.Be used for the antirust of the metals such as bridge, boats and ships, pipeline.
Along with people to the pay attention to day by day of the aspects such as environment protection, safety in production and to the understanding of Sustainable Healthy Development; countries in the world are more and more higher to the environmental requirement of coating, and the height of its VOC content becomes the standard whether a kind of coating belongs to environmental protection coating material of weighing to a certain extent.Under the driving of national environmental protection rules, the development of Coating Industry in Our Country just strides forward towards the direction of convenient construction, saving resource, health environment-friendly, and safe, nontoxic, efficient water-borne coatings just increases rapidly with the impetus of advancing by leaps and bounds.Therefore, advance exploitation, production and the use of water-borne coatings, be the developing direction of domestic and international coating industry always.
The characteristic of solvent epoxy varnish rust-inhibiting paint: 1, paint film all has good sticking power to metal (steel, aluminium etc.), pottery, glass, timber isopolarity ground, and volumetric shrinkage is low; 2, the chemical resistance performance is good; 3, has certain toughness; 4, wetted surface there is certain wetting power; 5, can cooperate with various kinds of resin, make multiple coating, but Air drying, but also high bake has satisfied different construction requirements.The defective of solvent epoxy varnish rust-inhibiting paint: 1, outdoor weatherability is relatively poor; 2, curability at low temperatures is poor; 3, discharge a small amount of hazardous and noxious substances, be detrimental to health contaminate environment.
The water-base epoxy rust-inhibiting paint is maximized favourable factors and minimized unfavourable ones, and has acted on all advantages of solvent epoxy varnish coating, has overcome its deficiency, and weathering resistance is better, has the characteristics such as low toxicity, safety and environmental protection, easy construction.
