Description
Technical field
The invention belongs to macromolecule membrane preparation field, be specifically related to a kind of organic/inorganic composite material multipurpose and protect
Protect lining form preparation method.
Background technology
In recent years, developing rapidly and the propelling of coastal area economic construction, ocean space along with marine economy
Utilizing process to accelerate, maritime concrete such as wave resistance carries, harbour, off-shore airport, seabed tunnel and bridge spanning the sea etc.
Apply the most extensive.Meanwhile, due to the impact of sea water long period of soaking, erosion, stormy waves and tide, sea
Ocean Structural Engineering etching problem is the most prominent, and the safety of marine concrete structure engineering and durable in serious harm
Property, bring huge economic loss to China.If Marine reinforced concrete structure engineering is taked effective anticorrosion
Measure, it is possible to being greatly reduced the loss caused because of corrosion, therefore, the corrosion of marine concrete structure is prevented
Problem of protecting more and more comes into one's own.
Good quality concrete and suitable protective layer thickness are the first line of defences improving durability, but can not protect
The durability that card concrete is long-term.Avoid the generation of corrosion failure, especially in the marine environment of severe corrosion,
Should take the anticorrosive measure added, coating technology is concrete main " addition thereto ", is conventional
Method.Its effect be reinforced concrete surface formed be difficult to permeable, be difficult to the cover layer breathed freely, to stop
Or delay villaumite, water and air to penetrate in concrete, so that the corrosiveness of reinforcing bar is restricted, reach steel
The durability of tendon concrete structure.
Coating technology is that marine concrete structure protects important and effective method, and conventional marine concrete structure is rotten
Erosion protective coating continued to use metal protection material, typically use chlorinated rubber, polyurethane, chlorosulfonated polyethylene and
The coating such as epoxy, its combination property is not met by the requirement of harsh marine environment to a certain extent.Generally
Corrosion-inhibiting coating is made up of multiple structures such as anti-corrosion primer, intermediate coat and finish paints.The most frequently used protection system is epoxy
Infiltration priming paint+thick paste type epoxy intermediate layer+polyurethane finish, from the point of view of actually used situation, its combination property
Be not met by the requirement of harsh marine environment, be primarily present the deficiency of following several respects: one, elastic low,
Bad mechanical strength, it is difficult to opposing temperature in four seasons alternation and the external force collision destruction to coating, especially winter
When temperature is relatively low, material fragility is relatively big, is just more difficult to keep out the collision of hull even floating ice；Two, coating thin,
Closure is poor, it is impossible to stop intrusion and the infiltration of extraneous corrosive medium；Three, paint solidification is slow, and construction is by the external world
The impact of condition is serious, such as the condition such as outdoor temperature, humidity；Four, to contain volatility molten for coating great majority used
Agent, is easily formed pin hole, unfavorable to the impermeability of coating, more due to the existence of solvent flashing, causes to environment
Serious pollution；Five, need to process ground, the most repeatedly spray, make troubles to construction and construction period is long.
