Description
Technical field
The present invention relates to the protective system technical field, a kind of heavy-duty coating that is used for ocean steel construction.
Background technology
There is the heavy-duty coating of similar applications to have three kinds with the present invention in the known technology at present: polyester glass-flake coating, spray polyurea coating and clinkery epoxy powder coating.
According to foreign literature, wherein the polyester glass-flake coating has been used for offshore drilling platform.Vibrin is the radical polymerization of being undertaken by initiator, and polymerization velocity is fast, and follows heat release, and therefore, the polyester glass-flake coating generally uses the application of two-component spraying machine.Coatingsurface can stop curing because of the oxygen in the ingress of air, and therefore, coating surface must be used the paraffin starvation, otherwise coating surface is difficult to drying.The curable polyester process has substantial contraction, can disperse string stress effectively though add glass flake, can not thoroughly eliminate stress.In a word, the polyester glass-flake coating requires high to preparation of construction, complicated operation.
About spray polyurea coating, because isocyanic ester and amine are swift in response, therefore must use special-purpose bi-component spray automatic doubler surface glouer, this specific equipment is very expensive.The spray polyurea coating systems of Huntsman International LLC's invention, Chinese patent publication number: CN01816689.X according to the content of being put down in writing in the patent document, though it has reduced isocyanic ester and amine speed of response as can be known, but still needs the bi-component spray automatic doubler surface glouer.Equally, because isocyanic ester and amine are swift in response, coating is poor to the base material wetting property, causes poor adhesive force.
The patent No. is: CN99124013.8, the content of putting down in writing in CN200610049566.9 two patent documents as can be known, its disclosed clinkery epoxy powder coating need be in the paint line application of special use, generally need in the spraying coated article to be heated to 250 ℃ with Medium frequency induction, therefore, the most suitable uniform specification of clinkery epoxy powder coating, the tubing that batch is big, and other application is subjected to certain restriction, as be not suitable for the thin-walled steel plate, and can not coating, be not suitable for short run, many kinds.
Summary of the invention
In order to overcome the defective that exists in the above-mentioned technology, the object of the present invention is to provide a kind of heavy-duty coating that is used for ocean steel construction, make protective system on coating performance, compare with polyester glass-flake coating, spray polyurea coating and clinkery epoxy powder coating, antiseptic property is suitable, and is more excellent aspect sticking power, hardness; Overcome the drawback of this three kinds of coating application equipment requirements height, complex procedures; Coating of the present invention does not contain organic solvent, and the coating cost is low; Adopt knife-coat application, one time thickness can reach 500 microns, and the application expense is low.
For achieving the above object, the present invention adopts technical scheme as described below:
