Abstract
The invention discloses an aqueous low-surface treatment coating for iron power transmission tower surface protection and a preparation method for the aqueous low-surface treatment coating, and belongs to the field of anti-corrosion coatings applied to coating protection of a rusted iron power transmission tower. The aqueous low-surface treatment coating consists of the following components in percentage by mass: 50-63 percent of single-component ternary copolymerization aqueous resin, 5-19.5 percent of anti-rust pigment, 6-21 percent of volume filler, 0.5-8.5 percent of a rust conversion stabilizer, 0.5-5 percent of a flash inhibitor, 10-20 percent of an auxiliary agent and 1-5 percent of deionized water. The coating disclosed by the invention has a good rust conversion stabilizing function and can be cured under normal temperature; the room-temperature viscosity is 25s, and the adhesive force is 5MPa; a base material for surface treatment St2 is coated with neutral-salt-resistant fog 1000h. The construction technology of the low-surface treatment coating is simple; the low-surface treatment coating is non-toxic and environment-friendly and is excellent in protection performance.

The present invention relates to the protection field of hardware and the Development Techniques field of single-component water-based low prepared surface rust proof paint under the atmospheric environments such as in-service electric power pylon.
Background technology
The safe and reliable operation of electric power pylon is most important for guarantee electric power reliable delivery.In some specific environment (as heavily contaminated manufacturing district), in atmosphere pollution, the effect of corrosive chemical components makes steel tower more easily corrode, shorten the work-ing life of steel tower, even jeopardize steel construction security and cause transmitting line security incident.Electric power pylon is prevented that carrying out effective maintenance not only can save substantial contribution for country, and power transmission sequence safety operation level can be improved.High-quality application needs to carry out the strict surface treatment such as sandblasting to steel structure surface, Sa2.0 ~ Sa2.5 rank need be reached, for just under arms be located in field or baroque steel system, this type of strict surface treatment cannot be carried out, application is carried out according to conventional coating, coating is difficult to ensure at the sticking power of substrate surface, easily underfilm corrosion occurs, can not meet requirement of shelter.Therefore, can directly be coated in without strict surface-treated metallic surface, still can play good protection effect low surface treatment paint significant for electric power pylon Corrosion Maintenance; The exploitation of high-performance low prepared surface maintenance paint is also one of important subject in current coating industry.
Low surface treatment paint mostly is solvent based product now, and as H2000 application over rust priming paint, ONIVAN series priming paint etc., a large amount of organic solvent can cause the waste of resource, more exists environment and pollutes and destroy.Water-borne coatings has the advantage of environmental protection, and thus released one after another multiple water-based low surface treatment paint product both at home and abroad, and as RF-GSO5 series aqueous rust-proof coatings, U.S. APP water-thinned antirust primer etc., China's waterborne rusted paint development is relatively late; General water-based low surface treatment paint multiselect weakly alkaline emulsion resin (pH is at 9 ~ 10 range stabilises) as film forming matter (as the people such as Liu Jing section utilize MALEIC ANHYDRIDE and C5 petroleum resin to carry out modification to Semen Lini oil and and nucleocapsid benzene emulsion composite as film forming matter, Xue east magnitude people with pure third and styrene-acrylic composite emulsion as film forming matter), acid rust transforming agent or reactive pigment can not be added, otherwise demulsifying phenomenon can occur, therefore the barrier propterty of coating is lower.People regulate the acidity of resin emulsion by the interpolation of phosphoric acid and auxiliary agent etc., improve the stability of this system to a certain extent, but the barrier propterty of coating is still very limited.
The present invention adopts the emulsion resin containing acidic-group on molecular structure as filmogen, this resin not only has better stability, can also react with substrate surface corrosion, both well compatible with the antirust component of multiple acidity, make again film have better adhesion property at substrate surface.Be selected to membrane substance and functional component by appropriate design, solve the consistency of film forming matter and acid function composition, develop the high-performance water-based low surface treatment paint with rust stable conversion function.
