Description
Technical field
The invention belongs to chemical material technical fields, and it is interim for cupric nonpolluting coating that specifically the present invention relates to one kind
The environment-friendly type aqueous paint and preparation method thereof of protection.
Background technique
Since on January 1st, 2008, the whole world was forbidden to use the antifouling paint containing organotin, scientific research personnel has been put into largely
Energy be used for novel antifouling agent exploitation, mainly include copper class anti-fouling agent (such as cuprous oxide, cuprous sulfocyanide, organic copper
Close object (copper pyridine, phenyl copper, methyl ethylene lithium copper, ethyl lithium cyanide copper, trifluoro second boron cupric dibutyldithiocarbamate etc.), copper chelate (mercapto
Yl pyridines copper oxide, picolinic acid amide copper, acetylacetone,2,4-pentanedione aluminum bronze, ethylene diamide aluminum bronze etc.)), organic anti-fouling agent (such as pyrrole
Pyridine zinc, Irgarol 1051, TCPM, TCMTB, SeaNine211, KH101, Econea etc.), natural prodcuts anti-fouling agent (such as nicotinoyl
Amine, Kaempferol glucoside, coumaric acid polygonin ester, carbohydrate oxidase etc.).Copper class anti-fouling agent has wider antifouling activity, right
Barnacle class, dwell pipe worm and most of algae etc. all have stronger antifouling activity, are in current antifouling paint using most
Main anti-fouling agent is that antifouling paint plays one of most critical component of antifouling effect.Meanwhile in order to further increase to waterside liverwort,
The inhibition adhesion effect of the algae such as water cloud class and curved bar algae, often compounds organic anti-fouling agent, to reach superior anti-fouling effect.
It is cuprous oxide (Cu using in the best copper class anti-fouling agent of most, effect in current cupric antifouling paint2O).It is anti-
After dirty coating surface and contact with sea water, cuprous oxide, which decomposes, generates cuprous ion (Cu+), and gradually dissolved to seawater, in coating
Surface forms the toxic microbedding that a layer thickness is more than ten microns, the Cu in microbedding+It can enter in marine growth larva and sporinite, it can
It reduces the activation that apoenzyme is metabolized biological life in living organism and bio-longevity is shortened with this, and with solidifying protein
Effect, to play the effect of antifouling biodeterioration.
The Cu that cuprous oxide releases+It is unstable in the seawater, stable bivalent cupric ion (Cu will soon be converted into2 +), and utilized by the various bio-absorbables in seawater rapidly, or reacted with the organic/inorganic object in seawater, generate precipitating simultaneously
Loss of activity.
In conclusion cuprous oxide (Cu2O it is) the most main anti-fouling agent of current application, it is main plays antifouling substance
It is that it decomposes the Cu generated+, Cu+It is oxidized to Cu2+Afterwards, precipitating and loss of activity, no anti-fouling effect can be quickly generated.Cupric is anti-
After dirty coating construction, the cuprous oxide pole if the long period cannot be lauched, especially under the conditions of summer higher temperatures, in coating
Easily is caused anti-fouling agent activity to fail at copper oxide (CuO) by the dioxygen oxidation in air, the anti-pollution of coating is greatly reduced.
Currently, both at home and abroad for this problem also without effective solution method, only by control anti-fouling paint construction speed, to the greatest extent
Amount shortens the atmospheric exposure time to reduce the oxidation of cuprous oxide, can not fundamentally solve asking for cuprous oxide oxidation deactivation
Topic, also proposed high requirement to site operation progress monitoring.
The present invention is a kind of environment-friendly type aqueous paint and preparation method thereof temporarily protected for cupric nonpolluting coating surface, is adopted
It is main film forming matter with aqueous degradation resin, addition waterproof resin, pigments and fillers and related auxiliaries are formulated.This is environment-friendly type aqueous
Paint is coated in the cupric nonpolluting coating surface after dry solidification, can effectively completely cut off contact of the nonpolluting coating with air, avoid aoxidizing
Cuprous anti-fouling agent is oxidized, it is ensured that the anti-pollution of coating.Meanwhile the temporary protective material is in different ocean temperatures (6-25 DEG C)
Under will be slow dissolution (dissolution time be 7-15 days), completely new nonpolluting coating is exposed after having dissolved, with excellent soil resistance
Energy.
Summary of the invention
To overcome deficiency present in background technique, the present invention provides one kind temporarily to protect for cupric nonpolluting coating surface
The environment-friendly type aqueous paint of shield is mainly used in the interim protection of the new coating cupric nonpolluting coating such as ship, harbour and offshore platform,
Contact of the nonpolluting coating with air can effectively be completely cut off, cuprous oxide anti-fouling agent is avoided to be oxidized, it is ensured that the anti-pollution of coating.It should
Interim protection environment-friendly type water paint can thoroughly solve the problems, such as cuprous oxide oxidation deactivation in air, and cupric anti-fouling paint is in high temperature
Also cocoa shifts to an earlier date long period construction under weather, is conducive to the control of protective coating site operation progress.
