Abstract
A waterborne epoxy coating comprises the following components in percentage by mass: 50-80% of epoxy resin, 10-25% of curing agent, 4-10% of film-forming aid, 0.1-1% of defoaming agent, 1-5% of leveling agent, 1-5% of wetting agent and the balance of deionized water, wherein the curing agent is an amine curing agent and is a polyamide curing agent or an amide curing agent.
Description
Technical field
The present invention relates to a kind of coating, relate in particular to a kind of water-borne coatings for industrial antisepsis erosion.
Background technology
Corrosion causes the annual financial loss in the whole world great to the mankind, and adopting coating to carry out protection against corrosion to metal is economic, practical, effective means.Metallic corrosion refers to that metallic substance is subject to the chemical action of surrounding medium or electrochemical action and the phenomenon damaged.Metal is generally made through processes such as catabiotic smelting, electrolysis by the ore in stable state, therefore, metal itself has and gives off energy, return to low energy and the tendency of stable virgin state, therefore the corrosion of metallic substance is a spontaneous process in chemical thermodynamics, metal has the natural tendency of corrosion.The application of organic coating has the history of thousands of years with development, and ancients make oil-base paint with the material such as natural resin and mineral substance, and utensil is decorated and protective treatment.Along with the widespread use of the metallic substance such as iron and steel, organic coating protection against corrosion starts to occur as a subject also developed.
Water-borne coatings has many advantages and becomes study hotspot and the main development direction of metal anti-corrosive paint.Past heavy duty system is the forbidden zone of water-borne coatings always, and the development of water-borne coatings technology has in recent years had important breakthrough to make it enter this manor.Owing to relating to multiple industrial circles, the research and development of aqueous heavy anti-corrosion paint have obtained coating production enterprise and research worker's attention.
Heavy-duty coating is mainly used in the outstanding severe rugged environment of etching problem has following five aspects with the industrial sector Application Areas that is not easy to short-term maintenance: 1. emerging oceanographic engineering: Offshore Units, seashore and bay structure, offshore drilling platforms; 2. Modern Traffic transportation: freeway guardrail, bridge, ships and light boats, freight container, train and railway facility, automobile, airport installation; 3. energy industry: water conservancy project equipment, water pot, gas tank, petroleum refinement equipment, oil stockpile equipment oil pipe, oil tank, power transmission and transforming equipment, nuclear power, colliery; 4. large size industrial enterprise: the pipeline of paper making equipment, medical equipment, food chemistry equipment, metal vessel inside and outside wall, chemical industry, iron and steel, petrochemical plant, storage tank, mine smelting, cement mill equipment, the ground that has corrosive medium, wall, cement components; 5. urban operating mechanism: gas line and facility thereof are as gas chamber, natural gas line, drinking-water facility, refuse treatment plant etc.Also be that the most successfully water-borne coatings is the rich zinc heavy-duty coating of aqueous epoxy resins, urethane and inorganic silicic acid for what weigh corrosion-resistant field at present.
Summary of the invention
The object of the present invention is to provide a kind of good stability, shielding high, and metal substrate is there is to the epoxy water-borne coatings for industrial antisepsis of good adhesion and wet attached power.
For achieving the above object, the present invention adopts following technical scheme:
Epoxy water-borne coatings, is made up of epoxy resin, solidifying agent, film coalescence aid, defoamer, flow agent, wetting agent and deionized water, is made up of following massfraction:
In technical scheme of the present invention, described solidifying agent is amine curing agent.Described solidifying agent is preferably polyamide-based solidifying agent or amides solidifying agent.As SF650 type solidifying agent, not only there is solidification effect, also there is toughness reinforcing effect simultaneously.
Film coalescence aid of the present invention mainly adopts ethers film coalescence aid, as propylene glycol phenylate etc.
The defoamer that ordinary epoxy resin coating is used is all applicable to the present invention.As C-885 FBRA defoamer, 080 defoamer etc.
The flow agent that the present invention adopts is mainly BYK series flow agent, as BYK333, BYK354 etc.
The wetting agent that the present invention adopts is mainly PM-WET100, PM-WET101, PM-DISPERSANT5040 etc.
Compared with conventional solvent type epoxy resin, aqueous epoxy resins has not containing organic solvent or organic compound content is lower, good operation performance, most base material is had good sticking power, can in room temperature and moist environment, be solidified, easily and the advantage such as other polymerizable aqueous objects system is composite modified.
Embodiment
The following examples can make the present invention of those of ordinary skill in the art's comprehend, but do not limit the present invention in any way.
Embodiment 1
A kind of epoxy water-borne coatings, composed of the following components by mass fraction:
Above-mentioned each component is mixed, and stirring at room temperature 1 hour, leaves standstill and obtains coating provided by the invention.
Embodiment 2
