Description
Technical field
The invention belongs to technical field of coatings, particularly a kind of boats and ships protective system and its preparation method and application.
Background technology
4/5 of earth surface is ocean covering, and marine economy and marine industries play a part very important to the development of human society.China reaches km more than 18000 from reaching northern coast line length in the south, and north and south temperature differs 50 ℃, and marine life is numerous.Ocean environment is very harsh corrosive environment, boats and ships for a long time in such ocean environment, corrode extremely serious, and coating topmost anticorrosion means that are always it.Anticorrosion and the antifouling paint in ocean is the basis that forms Marine Paints.According to the environment for use of various facilities with require differently, derive again various series product, for example, marine finish, oceanographic engineering facility are with heavy-duty coating etc.
Wherein, marine finish is divided into again the speciality coatings such as the anticorrosion and antifouling varnish of hull bottom, ship hull paint, porch paint, interior cabin paint and damping noise-reducing.Due to the singularity of cabin, people, except paying close attention to the solidity to corrosion of cabin coating, go back its toxicity problem of special concern.Because the solidity to corrosion of coating has influence on active time and the military service performance of boats and ships, the toxicity problem of coating is related to crewman's health of human body and safety.
With the solventless epoxy coating that thinlyfluid epoxy resin is made have one-pass film-forming thick, be convenient to spraying, the feature such as normal temperature solidified, edges cover good, antiseptic property is excellent.Due to the organic solvent-free volatilization in construction process of this coating, obviously improved construction environment and the working security in cabin, improved operating efficiency, and film thickness and preservative effect are guaranteed.This coating is applied and has obtained good result of use at fresh-water tank and the ballast tank of large ship.Estimate that the popularization and application of solventless epoxy coating in ballast tank anticorrosive coating can reduce the Maritime Accident being caused by ballast tank heavy corrosion greatly.
In epoxy coating, add the resistance to corrosion that conducting polymer can improve epoxy coating greatly, mainly add at present polyaniline and polypyrrole, yet these two kinds of conducting polymers still exist series of problems in the middle of actual practical process.Polyaniline can degrade in the middle of use procedure, discharges poisonous, carcinogenic gas, serious harm HUMAN HEALTH, and polypyrrole is unstable, and in use easily decomposition, work-ing life are short.
Summary of the invention
The above-mentioned deficiency that the object of the invention is to overcome prior art, provides a kind of boats and ships protective system and its preparation method and application, to solve the technical problem that existing epoxypaint easily decomposes, antiseptic property is poor.
In order to realize foregoing invention object, technical scheme of the present invention is as follows:
A boats and ships protective system, comprises the component of following mass parts:
66.27～66.57 parts of epoxy resin
3.13～33.28 parts of kymenes
0.15～0.60 part of PEDOT/PSS
99.4～99.85 parts, water.
And a kind of method of preparing above-mentioned boats and ships protective system, comprises the following steps:
PEDOT/PSS is dissolved in the water, is mixed with the aqueous solution of PEDOT/PSS;
To in the aqueous solution that add PEDOT/PSS at the epoxy resin taking and polymeric amide interval, carry out mixing treatment.
And, the application in structure surface treatment in seawater of above-mentioned boats and ships protective system.
Above-mentioned boats and ships protective system be take PEDOT/PSS as conductive agent, by itself and epoxy resin and polymeric amide, acts synergistically, and effectively suppresses the decomposition of polymeric amide, and has given water-fast, alkaline-resisting and artificial weathering ageing resistance's antiseptic property of this boats and ships protective system excellence.In addition, this boats and ships protective system be take water as solvent, and the suppressed decomposition of polymeric amide, therefore, and this boats and ships protective system safety and environmental protection.Just because of this boats and ships protective system, in seawater, there is this excellent preservative effect, effectively expanded its range of application, as the application in structure surface treatment in seawater.
The preparation of above-mentioned boats and ships protective system only need be carried out interval mixing treatment by each component according to its formula, and it requires low to processing condition, thus its productivity and good article rate high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is before embodiment of the present invention 1-4 and comparative example's 1 coating formation coating are carried out galvanic corrosion and coating photo afterwards; Wherein, figure a-e is respectively coating that coating in comparative example 1, embodiment 1, embodiment 2, embodiment 3 and embodiment 4 the forms photo before galvanic corrosion, and f-j is respectively coating that in comparative example 1, embodiment 1, embodiment 2, embodiment 3 and embodiment 4, coating forms at the photo after 200 hours through electrochemistry accelerated corrosion.
