Description
Technical field
The present invention relates to a kind of new anti-corrosion coating and preparation method thereof, more particularly, relate to a kind of water corrosion-resistant epoxy paint and preparation method thereof.
Background technology
The metallic corrosion meeting brings huge financial loss, causes number to waste with hundred million tons iron and steel.The iron and steel output of China wherein has 30% owing to corrosion has been wasted up to hundred million tons at present.On " development forum, 2009 fringe Hong Kong, Macao and Taiwan science technology and industry (corrosion prevention) ", brainstrust has also been inquired into the corrosion and protection of metallic substance to topic, propose simultaneously to reduce unnecessary financial loss in order to prevent metallic corrosion, must strengthen applying of anticorrosion technique.People have studied a lot of anti-corrosion methods for many years, and convenient, the most economic method is with protective system the metallic surface to be protected at present.
Traditional solvent-borne type protective system can discharge a large amount of VOC, and living environment and people healthy had potential threat.Gradually enhancing along with people's environmental consciousness, Environmental Protection in China general bureau has just promulgated " technical requirements of water-borne coatings environmental labelling product " in 2002, the quantity discharged of restriction VOC, with the pollution of minimizing coating to environment, thereby water-based anticorrosive paint becomes the focus of falling over each other to study.Water-based anticorrosive paint mainly is take water as solvent and dispersion agent, and compare production and transportation with the solvent-borne type protective system safer, do not contain or contain a small amount of solvent, and the VOC burst size is extremely low, is applicable to indoor and outdoor environment.At present, water-based anticorrosive paint has almost reached the performance of solvent-borne type protective system.The water-based anticorrosive paint kind is a lot, mainly contains epoxy, vinylformic acid, inorganic zinc silicate and polyurethane coating etc., wherein industrialized aqueous epoxy coating and aqueous inorganic zinc-enriched coating, the water soluble acrylic acid coating of mainly containing of success.
Water soluble acrylic acid protective system membrane formation mechanism is complicated, and sticking power slightly is short of than water-base epoxy; The aqueous inorganic zinc silicate anti-corrosive paint requires too high to processing base level, and easily forms the high density zinc salt when not using finish paint; Property of Waterborne Polyurethane is fine, but cost is higher.
Consider above-mentioned practical situation, those skilled in the art is being devoted to study a kind of novel water corrosion-resistant epoxy paint always, replace existing solvent-borne type protective system, and simultaneously need again to have sticking power preferably, lower cost and better simply preparation method.

According to one embodiment of the invention, dispersion agent is 0.6% EFKA-5065 dispersion agent and 0.4% EFKA-4050 dispersion agent, and flow agent is 0.3% EFKA-3777 flow agent and 0.3% EFKA-3239 flow agent, and talcum powder is 1250 orders.Above-mentioned per-cent all is weight percentage.
According to one embodiment of the invention, B group component is that 85% Resins, epoxy 128 and 15% epoxide diluent AGE mix.
According to one embodiment of the invention, water corrosion-resistant epoxy paint allows 0.1% impurity.
According to a further aspect in the invention, also provide a kind of preparation method of water corrosion-resistant epoxy paint, comprising: step 1 adds W220 aqueous epoxy curing agent, distilled water and dispersion agent in Scattered Kettle; Step 2, middling speed is disperseed; Step 3 adds red iron oxide, zinc phosphate, aluminium triphosphate, talcum powder and organobentonite; Step 4, high speed dispersion; Step 5, the material behind the grinding distribution; Step 6 adds defoamer and flow agent; Step 7, Uniform Dispersion; Step 8 adds B component and mixing.
According to one embodiment of the invention, the middling speed jitter time is 15 minutes, and the high speed dispersion time is 20 minutes.
According to one embodiment of the invention, step 5 adopts sand mill to grind.
Adopted technical scheme of the present invention, can obtain a kind of novel water corrosion-resistant epoxy paint, have higher base material sticking power, its chemicals-resistant of filming better performances, can mix with other waterborne polymerics use, and stable system, antiseptic property is excellent.
Description of drawings
In the present invention, identical Reference numeral represents identical feature all the time, wherein:
Fig. 1 is water corrosion-resistant epoxy paint preparation method's of the present invention schema.
Embodiment
Further specify technical scheme of the present invention below in conjunction with drawings and Examples.
The present invention discloses a kind of better performances with higher base material sticking power, its chemicals-resistant of filming, can mix with other waterborne polymerics use, and stable system, the water corrosion-resistant epoxy paint of antiseptic property excellence, the component of this coating is broadly divided into two groups of components of A, B, and wherein wt is than A: B=6: 1.The below describes the content of each component in detail, and the preparation method of water corrosion-resistant epoxy paint of the present invention.
Take the A component of 1kg as example, in the A of 1kg component, the content of each component is as shown in the table:
