Description

A kind of ocean structure biology base surface layer repair materials
Technical field
The invention belongs to ocean structure surface layer recovery technique fields, it particularly relates to a kind of ocean structure biology Base table layer repair materials.
Background technique
China ocean area is larger, and for available marine resources compared with horn of plenty, ocean has been increasingly becoming support China's economy The key areas of development and national defense safety.Various marine settings and job facilities be Activities of Ocean provide it is essential Means and precondition.Marine engineering equipment is used and is on active service in marine environment for a long time with marine structure, unavoidably Ground is influenced by marine environment, conversely, as the use of some chemicals also adversely affects marine environment and ecology. Wherein, corrosion of the marine environment to engineer equipment and works seriously affects the service performance of works, safety, durable Property etc..Therefore, how effectively to be protected marine structure has been an extremely urgent and far-reaching job.
Representativeness anti-corrosion method used in ocean structure mainly has three classes at present: (1) coating class, organic zinc or inorganic The mixture of zinc and epoxy-resin systems；(2) organic lining, predominantly polyethylene, polyurethane, Epoxy/Polyurethane, solid in water Change type epoxy resin；(3) metal, predominantly titanium or sea water resistance stainless steel are coated.With organic lining class in above-mentioned three classes method Anti-corrosion effect is preferable, its long durability of metal-electrochemical anti-corrosive is poor, and resinae is larger to the pollution of water body, and for wet Face bonding still has certain deficiency.
Summary of the invention
In order to solve the above technical problems, ocean structure strong the present invention provides a kind of adhesive capacity and nontoxic waterproof is given birth to Object base table layer repair materials.
A kind of ocean structure of the present invention biology base surface layer repair materials, the repair materials are modified polyurethane Coating is repaired on surface layer, is ternary component；In ternary component, component A is modified polyurethane, and B component is curing agent, chain extender, friendship Join agent and oxidant, component C are filler；Ternary component in parts by mass, including 100 parts of modified polyurethane, curing agent 50~60 Part, 1~2 part of chain extender, 1~2 part of crosslinking agent, 6~10 parts of oxidant, 100 parts of filler.
A kind of ocean structure of the present invention biology base surface 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 biology base surface layer repair materials, the curing agent are trimethylolpropane TDI addition product；The chain extender is ethylene glycol or/and 1,4- butanediol；The crosslinking agent is pentaerythrite.
A kind of ocean structure of the present invention biology base surface 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 biology base surface 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 biology base surface layer repair materials, the filler are conch meal, and mesh number is 300~800 mesh.
A kind of construction technology of ocean structure biology base surface layer repair materials of the present invention, the construction technology tool Body are as follows: 1) be uniformly mixed with oxidant curing agent, chain extender, the crosslinking agent in B component；2) two kinds of components of A, C are weighed, and It stirs evenly；3) B component is poured into A, C mixture, stirs 30s, carries out smearing construction.
The mechanism of action: 1) polyurethane system: contain isocyano group (- NCO) and carbamate in polyisocyanate molecule chain Base (- NH-COO-), activity and polarity with height.It encounters containing materials such as active hydrogen, moist surfaces, all has excellent Chemical adhesive power.2) introducing DOPA etc., there is catechol structure to be modified to polyurethane system, and DOPA itself has excellent It is different stick, adhesive property.DOPA forms benzoquinones under the action of oxidant, so that be cross-linked with each other between protein, secondly, DOPA can also be combined with metal ion and its oxide (Fe, Mn) and silicon etc., make its be firmly bonded in rock, metal, Cement concrete constructions object surface.
The present invention uses for reference marine mussel makes it be attached on various substrates securely by secreting mussel adhesion protein (MAPs) Surface the characteristics of be designed and implement.This kind of mussel adhesion protein omnipotent adhesive capacity with super strength and waterproof adhesion energy Power, and there is nontoxic and biocompatibility.Therefore this kind of adhesion protein is introduced into existing polyurethane coating system, on the one hand Underwater Adhering capacity 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 has inherent as a kind of marine organisms with marine environment Compatibility.It is processed to that the powder of certain mesh number is made, 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 biology base surface layer There are superpower omnipotent adhesive capacity and waterproof Adhering capacity, and there is nontoxic and biocompatibility, reduces chemical industry coating material Pollution to water body；Using conch meal as filler, pollution of other chemical fillers to water body can be also reduced.
