Abstract
The present invention is originally related to a kind of watersoluble modified epoxy resin ship heavy antisepsis antifoulant and its preparation process.The resin belongs to extra-weather-proof type, and is applied to have many advantages, such as that good gloss retention, outdoor durable and pollution resistance are good in modified epoxy resin paint；The hardness and shock resistance of paint film are enhanced, and the coating as superior performance is applied to the metal heavy-duties field anti-corrosions such as ship, steel structure, has broad application prospects.
Description
Technical field
The present invention relates to aqueous epoxy resins preparing technical field, more particularly to a kind of aqueous fluorinated silicone modified asphalt mixtures modified by epoxy resin
Fat ship heavy antisepsis priming paint and its preparation process.
Background technology
Compared with traditional solvent based coating, water paint has price low, safe to use, saves resource and the energy, subtracts
The advantages that few environmental pollution and public hazards, thus become the Main way of current development coatings industry.It is but environment-friendly type aqueous at present
The film of resin has that water absorption rate is higher, heat resistance, water resistance and weatherability are poor, especially in hardness, shock resistance and resistance to molten
Agent etc. is not so good as solvent based coating.Thus in many fields, the application in especially heavy antisepsis field is restricted；People grind
Study carefully the comprehensive performance being modified to it to improve film.
Ocean engineering steel construction is the main ocean engineering structural construction using Steel material as skeleton.Therefore pass through Study on Steel
The corrosion protection technology of material is lost with reducing marine corrosion caused by national economy, is had for the development of country great
Meaning.This complicated spontaneous corrosion medium of seawater can cause very big destruction to being in metal structure therein, be a kind of molten
There is the salt electrolyte largely based on sodium chloride.It is different from simple salt solution again.The ocean of ocean engineering steel construction
Corrosion and protection be a complexity and it is severe the problem of.Marine corrosion environment is broadly divided into 5 zones, respectively：Atmospheric region flies
Splash area, Tidal zone, submerged zone and ooze area.Ocean engineering steel construction is shown not in the corrosion condition of different corrosion zones
The characteristics of same.The wherein corrosion rate highest of splash zone and Tidal zone, it is maximum to corrosion protection technology requirement difficulty.For difference
Zone take different preventive means, such as coating coating, vaseline cladding aseptic technic, electrochemical protection, material modification.Its
Middle coating anticorrosive paint is a kind of effective important means in corrosion protection method.Anticorrosive paint (Heavy-
Duty Coating) refer to for conventional anticorrosive paint, it can be used in relatively harsh corrosive environment, and can reach
A kind of anticorrosive paint of protection period longer than conventional anticorrosive paint.Heavy antisepsis has both sides meaning, and one refers to that corrosive environment is disliked
It is bad；Two refer to protect long lifespan.Heavy antisepsis technology is developed by general anti-corrosion, and the application of anticorrosive paint is related to industrial and mineral
The every field such as enterprise, energy industry, ocean engineering and communications and transportation.
Do not have in water paint or contain seldom organic solvent but using water as decentralized medium, odorlessness, no
Inflammable, cheap, storage transport and safety in use greatly improve, and performance is good.With national policy pair
The increasingly strict requirement of environmental protection, the content for reducing and controlling VOC in coating are an important measures of environmental protection.It is aqueous
Many performance advantages of anticorrosive paint virtually determine its more excellent than the application present situation of solvent type anticorrosive paint in prospect more
It is wide.
