Water-based self-rotating rust anticorrosive paint product features
Date:
2020-05-06
Water-based self-rotating rust anticorrosive paint is a single component, using water-based acrylic acid, special monomer copolymerization of water-based modified copolymer, due to the selection of self-emulsifying "core-shell" structure of water-based special emulsion, rust transfer raw materials and non-toxic anti-rust pigment. The coating provides long-term and efficient protection for rusty steel surfaces without pretreatment, which not only significantly prolongs the service life of anti-corrosion topcoat, but also makes the anti-corrosion coating process simpler, more efficient, economical and environmentally friendly. The new method is based on a new chemical chelation method to convert the rust on the iron surface into a hydrophobic passivation layer. Compared with the traditional system, the rust conversion anti-corrosion system provides longer-term protection before re-corrosion occurs. The high-molecular polymer molecules coated on the rusted metal surface are aligned in the film formation: one end of many anchoring groups on the polymer chain is bonded with iron ions such as Fe(OH)2\Fe(OH)3, FeO\Fe2O3, which are the main components of rust, to form highly stable chemical coordination bonds, and the other end forms a typical hydrophobic barrier. On the metal surface, anodic/partial cathodic protection is formed. Organic molecules firmly combined with the metal surface process called coordination or chelation, the formation of a three-dimensional structure of the network film, with high hardness and strong adhesion, water resistance, salt resistance, alkali resistance, acid resistance. In order to obtain effective and durable corrosion inhibition effect and anti-rust purpose. Design purposes: the product is a high-grade water-based rotating rust paint, due to the unique mechanism, scientific design, advanced technology, excellent performance, widely on the rust without pretreatment of the steel surface to provide long-term protection, not only significantly extend the service life of anti-corrosion paint, and anti-corrosion coating process is more simple, efficient, economic and environmental protection. Product features: 1. Simple operation and saving working hours. It requires less surface treatment than other steel anti-corrosion coating technologies. It does not need to polish rust, water washing, pickling, sandblasting, phosphating, etc., and anti-corrosion coating becomes very simple. 2, reduce the construction intensity and cost, improve the coating efficiency, especially for mechanical rust removal can not reach the special-shaped structure effect advantage is more obvious 3.PH neutral, no corrosion to the steel substrate. 3, catalytic reactivity, get a dense black inert protective layer, excellent anti-corrosion performance. 4. Low odor, water-based system, very low VOC, no lead, acid, no flammable solvents. 5. It has longer anti-corrosion protection than ordinary rust transfer system, and improves the service life of anti-corrosion topcoat several times. Good tolerance to surface iron chloride impurities, which is very important for ship systems. 7, easy construction, can be used for dry or wet rust surface. 8, and most of the commercially available solvent-based (acrylic, polyurethane, epoxy, alkyd, amino, etc.) paint matching is good, and will not occur and topcoat stratification and bleeding. 9. Physical parameters: paint surface: flat color: light yellow milky liquid, solid content,>: 45±1% PH:7 theoretical coating rate: about 20-300m/kg (dry film thickness below 10 microns) temperature resistance: maximum (dry) 120 ℃ flash point: no specific gravity: about 1.15kg/liter finger touch dry: about 30-40 minutes (23 ℃ 2 ℃) complete curing: 7 days (20 ℃) storage time: 1 year (20 ℃)
