Abstract

The present invention relates to a kind of with denatured silicate as vehicle with the coating of pure aluminium silicate as dispersate.Because the free radical reaction of silanol, coating of the present invention can form a kind of functional membrane special, that be similar to the full-inorganic of polymer organic coating, and described film has netted chemical structure form.Described film has stoped the loss of iron ion, therefore, has corrosion-resisting function, and can decompose the secretory product amino acid calcium colloid of ocean adhesivity biology and have harmless anti-fouling effect.Coating of the present invention also can be used as the inside and outside coating and the paint colorant of structural part, has nonvolatil smokeless, humidity control, antibiotic and anti-static function.

Description

Harmless antifouling paint with full-inorganic of permanent preservative property
The present invention relates to a kind of harmless antifouling paint with full-inorganic of permanent preservative property.
Developed since nineteen thirty-seven since the heat curing coating (Australian Patent number 1,042,317) of a kind of DAYMETCOAT by name, (USP 246263 to adopt the chemosetting method, 1970) and the self cure method (USP 4,086,616, the phosphoric acid method, USP 2,536, and 871, zinc oxide method), now developed the water glass coating series.But, when it is used as protective system, needs to increase zinc concentration bar none and just can prevent corrosion.
After thermal curing methods occurred, the water glass coating series was considered to for heavy equipment, is used for the steel structure of specific purposes, particularly is in those of desert and ocean environment, has preservative effect.But, having in most cases, it is used as the priming paint of coating or is used in combination with organic coating.
Phosphoric acid and phosphoric acid salt, for example silicon polyphosphate, titanium phosphate and metal oxide are the solidifying agent of known water glass coating as calcium oxide, aluminum oxide etc.; Glass fibre, carbon fiber etc. are then as its toughener.In addition, also has a large amount of this patents on the one hand that relates to.But, the main drawback of water glass coating series, for example non-watertight, inflexibility and tarnish etc. still do not solve.Therefore, use organic-inorganic composition coating usually, or replace with alkyl silicate coating.
In addition, the functional membrane that does not also have a patent to relate to by forming a kind of special inorganic acid salt solves anticorrosion and antifouling problem.
Recently, prevent to pollute international organization and ban use of deleterious antifouling paint by legal procedure.But, up to the present also do not have a kind of effective harmless coating to occur.
The purpose of this invention is to provide a kind of harmless antifouling paint with full-inorganic of permanent preservative property, described coating is according in ocean environment, and the adhering research of the mechanism of corrosion of iron and the adhesivity biology in the ocean is developed.
Another object of the present invention provides a kind of coating of coating structure thing ectonexine and colorant that is used to paint of being used for, and they have excellent tackiness, water-repellancy, humidity control, antistatic, antibacterium performance and make the will never fade performance of color.
A back purpose of the present invention directly relates to better succession and develops our ancestors' the lofty task of valuable cultural heritage, these legacy reside on the wall of grave and China Kongwryo on the colourful drawing that stays and pattern (make its will never fade).
The present invention and coating can prepare with diverse ways by its purposes.
The method I
M 2O/SiO 2Mol ratio is 0.4~0.25 silicate (M 2OSiO 2) solution mixes with ammonium chloride, makes NH 4Cl/SiO 2Mol ratio reaches wherein M=K of 0.2~0.5(, Na, and Li, Rb).Following reaction takes place subsequently:
Na 2O·nSiO 2+2NH 4Cl+H 2O=2NaCl+2NH 3↑+nSiO 2+2H 2O
Silica gel slaking certain hour that obtains by above-mentioned reaction and the denaturant gel attitude aminopropyl silica gel (xH that obtains being adsorbed with ammonia through washing 2SiO 3NH 4OHyH 2O), its NH 4OH/SiO 2Mol ratio preferably 0.25~0.5, this mixture and M 2O/SiO 2Mol ratio be 0.25~0.5 silicate solutions with 1~50: 100 weight ratio is mixed, and MX solution is distributed in this solution that obtains, and makes its MX/SiO 2Mol ratio reaches 0.01~0.05, obtains full-bodied denatured silicate solution (vehicle) (M wherein is K, Na, Li, Rb, Ba, Zn, Ca, Al, and X is Cl, F, Br) thus.
If in above-mentioned denatured silicate solution, add filler, pure aluminium silicate dispersate, metal oxide and metal-powder, then will obtain a kind of coating (pure aluminium silicate described herein is the M(I) 2The OM(II) OAl 2O 3NSiO 2MH 2O, wherein M(I) and the M(II) being respectively unit price and two valency metallic cation, n is SiO 2/ Al 2O 3Mol ratio, m is the mole number of water).SiO 2/ Al 2O 3Mol ratio preferably in 0.5~20 scope, Na 2Preferably in 1~10 scope, ion exchange capacity is 5~40 milligramequivalents/100 grams to the O/CaO mol ratio.The granular size of filler is 250~300 orders preferably.Vehicle preferably adds with pure aluminium silicate, and what add simultaneously also has one or both to be selected from ZnO, TiO 2, Fe 2O 3, BaO, Al 2O 3In metal oxide and one or both be selected from metal-powder among Zn, Fe, Al and the Cu, their add-on is respectively 30~40%(weight), 0~20%(weight) and 0~20%(weight).
When this coating uses, a kind of film with ionic adsorption and ion-exchange capacity will be obtained.
According to the mol ratio of filler and its add-on, the ion adsorption capacity of the film that is formed by coating changes in the scope of 90~110 milligramequivalents/100 grams, and ion-exchange capacity changes in the scope that 10~30 milligramequivalents/100 restrain.
When the application of paints that according to said method makes during in hull bottom, will form a kind of mineral membrane, this film is to cationic adsorptive power, and is higher 3 times than natural zeolite in cationic adsorptive capacity, to Ca 2+Ionic absorption more so (sees Table 1).
Infrared absorption spectrum analysis, X-ray diffraction analysis, the analysis of X-ray photoelectric and differential thermal analysis result show that described film has a kind of tridimensional network, thereby make it have ion-exchange and adsorption function.
The bio secretion that is adsorbed in hull bottom goes out a kind of viscous substance, and amino acid calcium colloid, this viscous substance will be transformed into a kind of polymer cohesiveness material with very strong cohesive force, and adhere to the hull bottom surface securely.
Because the surface of described film is contained and had very highly active alkali metal cation, it can be easily and other metallic cation generation ion exchanges.Therefore, described film can be with Ca from the adhesivity secretion generation-amino acid calcium colloidal solution that ocean adhesivity bio secretion goes out 2+Ionic adsorption is come out, thus weaken the adhesion strength of described adhesivity biology and they can not perch in the hull bottom surface.
Table 2 film is to the absorption and the exchange capacity of calcium ion
Adsorptive power 100 milligramequivalents of per 100 grams
Every square centimeter adsorptive power 0.06 milligramequivalent
Exchange capacity 17 milligramequivalents of per 100 grams
Every square centimeter exchange capacity 0.01 milligramequivalent
The juice equivalents 2 * 10 of ocean adhesivity biology -5Milligramequivalent
(every square centimeter)
As shown in table 2, the ion-exchange capacity of every square centimeter of described film is 0.01 milligramequivalent, and the amount of the calcium that ocean adhesivity bio secretion goes out is 2 * 10 -5Milligramequivalent.When showing described film, a little data the exchange capacity of calcium is much higher than the secretory volume of the calcium of described ocean adsorptivity biology.
Therefore, described film not only has the ability that absorption ocean adhesivity biology comprises all calcium that fungus secretion goes out, simultaneously also because in seawater, the absorption-desorption process of calcium and sodium is the constant reversible reaction.Therefore, as long as described film exists, it is to ocean adhesivity biology, and the antifouling ability that comprises fungi will be nonvolatil.
Described film also can obtain explaining that described film has prevented to adsorb owing to ionic the loss of the iron ion that produces from ionic absorption and fixed mechanism to the anti-corrosion capability of iron.
