Description
Technical field
The invention belongs to ocean structure top layer recovery technique field, it particularly relates to it is biological to arrive a kind of ocean structure
Base table layer repair materials.
Background technology
China's ocean area is larger, and compared with horn of plenty, ocean is increasingly becoming support China economy to available marine resources
Development and the key areas of national defense safety.Various marine settings and job facilities for Activities of Ocean carrying out there is provided essential
Means and precondition.Marine engineering equipment used in marine environment and is on active service for a long time with marine structure, unavoidably
Ground is affected by marine environment, conversely, as the use of some chemicals is also adversely affected to marine environment and ecology.
Wherein, corrosion of the marine environment to engineer equipment and works, badly influences the performance of works, safety, durable
Property etc..Therefore, how effectively marine structure to be protected has been an extremely urgent and far-reaching job.
Representative anti-corrosion method used in ocean structure mainly has three classes at present:(1) application class, organic zinc is inorganic
Zinc and the mixture of epoxy-resin systems;(2) solid in organic lining, predominantly polyethylene, polyurethane, Epoxy/Polyurethane, water
Change type epoxy resin;(3) metal, predominantly titanium or sea water resistance rustless steel are coated.With organic lining class in above-mentioned three classes method
Preferably, its long durability of metal-electrochemical anti-corrosive is poor, and resinae is larger to the pollution of water body for antiseptic effect, and for wet
Face bonding still has certain deficiency.
Content of the invention
For solving above-mentioned technical problem, the invention provides the ocean structure life that a kind of adhesive capacity is strong and waterproof is nontoxic
Thing base table layer repair materials.
A kind of ocean structure of the present invention bio-based top layer repair materials, the repair materials are modified polyurethane
Coating is repaired on top layer, is ternary component;In ternary component, component A is modified polyurethane, and B component is firming agent, chain extender, friendship
Connection agent and oxidant, component C is filler;Ternary component in parts by mass, including 100 parts of modified polyurethane, firming agent 50~60
Part, 1~2 part of chain extender, 1~2 part of cross-linking agent, 6~10 parts of oxidant, 100 parts of filler.
A kind of ocean structure of the present invention bio-based top layer repair materials, the modifying agent in the modified polyurethane
For catechol derivatives, dopamine or DOPA amine derivative.
A kind of ocean structure of the present invention bio-based top layer repair materials, the firming agent are trimethylolpropane
TDI addition products;The chain extender is ethylene glycol or/and 1,4- butanediols;The cross-linking agent is tetramethylolmethane.
A kind of ocean structure of the present invention bio-based top layer repair materials, the oxidant are used as initiator,
Selected from physical oxidizing agent or/and biological oxidant.
A kind of ocean structure of the present invention bio-based top layer repair materials, the physical oxidizing agent are sodium metaperiodate
Or potassium permanganate, phosphatic one or more;The biological oxidant is catechol-oxydase.
A kind of ocean structure of the present invention bio-based top layer repair materials, described filler is conch meal, and mesh number is
300~800 mesh.
A kind of construction technology of the ocean structure of the present invention with bio-based top layer repair materials, the construction technology tool
Body is:1) firming agent in B component, chain extender, cross-linking agent are mixed homogeneously with oxidant;2) two kinds of components of A, C are weighed, and
Stir;3) B component is poured in A, C mixture, stirs 30s, carry out smearing construction.
The mechanism of action:1) polyurethane system:Containing isocyano group (- NCO) and carbamate in polyisocyanate molecule chain
Base (- NH-COO-), its have the activity and polarity of height.Run into containing materials such as active hydrogen, moist surfaces, be respectively provided with excellent
Chemical adhesive power.2) there is catechol structure polyurethane system is modified to introduce DOPA etc., and DOPA itself has excellent
Different stick, adhesive property.DOPA forms benzoquinone so that be cross-linked with each other between protein in the presence of oxidant, secondly,
DOPA can be combining with metal ion and its oxide (Fe, Mn) and silicon etc. so as to be firmly bonded in rock, metal,
Cement concrete constructions thing surface.
The present invention uses for reference marine mussel makes which be attached on various base materials securely by secreting mussel adhesion protein (MAPs)
Surface the characteristics of be designed and enforcement.This kind of mussel adhesion protein has superpower omnipotent adhesive capacity and waterproof adhesion energy
Power, and there is nontoxic and biocompatibility.Therefore this kind of adhesion protein is introduced existing polyurethane coating system, on the one hand
Adhering capacity under water can be effectively improved;On the other hand, this kind or other pollutions of chemical industry coating material to water body are reduced.Furthermore,
Filler in the coating repair materials is conch meal, and shell sheet had with marine environment inherent as a kind of marine organisms
The compatibility.The powder body for making certain mesh number is processed to, as filler, can also reduce dirt of other chemical fillers to water body
Dye.
Compared with prior art, ocean structure of the present invention has with modified polyurethane in the repair materials of bio-based top layer
There are superpower omnipotent adhesive capacity and waterproof Adhering capacity, and there is nontoxic and biocompatibility, reduce chemical industry coating material
Pollution to water body;With conch meal as filler, can also reduce pollution of other chemical fillers to water body.
