Abstract
The invention relates to antifouling material and a preparation method thereof, in particular to antifouling material and a preparation method thereof, which aim at the condition of marine environment, prevent and remove the marine organisms adhered on surfaces of ships and marine structures and can form concave-convex microstructure surfaces through direct film formation. The invention belongs to the marine organism fouling protection field. Acrylic resin which can be hydrolyzed to release silicon oil, modified silicon resin containing antifouling active functional groups, and methyl silicone resin are shaken and mixed in a container according to the volume ratio of 1:1:2 and then are placed for 2 to 3 hours, then triethylenetetramine which accounts for 0.3 to 0.6 percent of the total volume is added as curing agent, is mixed in the same container and is evenly shaken to produce antifouling material solution, and the coating forms a concave-convex microstructure surface with regularity during the use. Compared with the prior art and product, the antifouling material and the preparation method have better effect of preventing the marine organisms from adhering and fouling without problem of environmental pollution.
Description
Technical field:
The present invention relates to a kind of anti-fouling material and preparation method thereof, particularly a kind of under the ocean environment condition, prevent and kill off passing through direct film forming and can forming anti-fouling material of concave-convex micro-structure surface and preparation method thereof of boats and ships and marine structure surface attachment marine life, belong to marine biofouling protection field.
Background technology:
At present, exist a large amount of marine organisms in the seawater, these marine organisms can adhere to the boats and ships and the generation of works surface that are in for a long time in the briny environment, and this adhewsive action can increase the running resistance of boats and ships, have a strong impact on the route speed of boats and ships, increase fuel oil consumption, also can destroy the corrosion protection coating on boats and ships and works surface simultaneously, thereby cause the corrosion breakage on hull and works surface, have a strong impact on its security.Therefore seeking suitable way prevents that marine organisms from having very important significance to stained the adhering to of boats and ships and marine structure.
The existing main path that is used for preventing marine biofouling is exactly the external coating antifouling paint at boats and ships housing and marine structure, and this class coating mainly is to contain organotin, Red copper oxide or DDT, to carry out antifouling by contained stain control agent to the strong toxic action of organism.But this class coating adheres to the halobiontic while in poisoning, also can do great damage to the marine eco-environment, and use progressively is being under an embargo.
Owing to take place halobiontic adhering at material surface, if therefore can effectively change the wetting property of material surface, improve hydrophobic ability, can reduce or reduce the possibility that marine organisms adhere to effectively, and because this mode can not produce damaging influence to ocean environment, so can provide the important technology approach for preparing nontoxic anti-fouling material.Studies show that, influence the infiltrating factor of solid surface and mainly contain two: the one, surface free energy; The 2nd, surface microstructure.When Solid Surface Free Energy reduced, hydrophobic performance will be enhanced, but the minimum surface that can access material at present can only can reach 6.7mJ/m
2, promptly by-CF
3Group is the compact arranged surface of sexangle, but the contact angle of its smooth surface and water also has only 119 °.Therefore,, make up surface micro-structure, change surfaceness and just become extremely important in order to obtain better hydrophobic effect.
Carrying out comparatively deep research aspect the low surface energy anti-fouling material both at home and abroad, but the practical application effect of such material is unsatisfactory.Subject matter is exactly still to have the part marine organisms to adhere in its surface generation, and these settled organismes must can obtain removing by external force.The reason that causes present low-surface-energy material the problems referred to above is exactly only to be that to rely on the low surface energy feature of material itself to carry out antifouling when being used to be prepared anti-fouling material, and hydrophobic effect is limited.For addressing this problem, domestic some low surface energy anti-fouling materials newly developed all combine with stain control agent at present, further improve anti-fouling effect.As publication number is CN1810903, title is the patent of anti-fouling ship paint with low biological surface energy, a kind of anti-fouling ship paint with low biological surface energy by resin with low surface energy, bio-extract (capsaicine, chitin) microcapsule, nano titanium oxide, microporous type silicon-dioxide and solvent composition is disclosed; Publication number is CN1296044A, the name be called low surface energy, repelling type dirt-proof paint and using method thereof patent disclosure a kind of environmental protection antifouling paint of forming by binding material, silane coupling agent, fluorochemicals, the natural stain control agent of pungent type, mineral filler and solvent.These prior arts are utilizing low-surface-energy material further to make up micro-structure surface, improve hydrophobicity, improve aspect such as anti-fouling effect and also relatively lack.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that exists in the prior art, design a kind of anti-fouling material and preparation method thereof at preventing and kill off boats and ships and the adhering to marine life of marine structure surface in the ocean environment, this material is discharged the acrylic resin of silicone oil by hydrolyzable, be prepared from after containing the modified silicone resin of antifouling activity functional group by volume ratio being mixed with methyl silicon resin, the back formation of filming has the surface of regular concave-convex micro-structure, thereby the hydrophobicity of this material is significantly improved, can prevent halobiontic stained better, this material does not use stain control agent, and environment is not had damaging influence.
To achieve these goals, anti-fouling material that the present invention relates to and preparation process thereof be with hydrolyzable discharge the acrylic resin of silicone oil, the modified silicone resin that contains the antifouling activity functional group, methyl silicon resin shake in container by 1: 1: 2 volume ratio and mix after left standstill 2-3 hour, the triethylene tetramine that adds cumulative volume 0.3～0.6% again mixes and shakes up in same container as solidifying agent and makes anti-fouling material solution, films to form to have regular concave-convex micro-structure surface.
The acrylic resin that the used hydrolyzable of the present invention discharges silicone oil is a hydroxyl silicon oil modified acrylic resin, and its structural formula is:
X1, X2 are H or CH in the formula
3R is the alkyl chain of C1-C7; M is the natural number of 2-12, and n is the natural number of 1-3; A is O element or NH
2Group; R1, R2 are the alkyl chain of C1-C7.
The modified silicone resin that contains the antifouling activity functional group that the present invention is used is the silane coupler modified acrylic resin of suspended side chain paeonol structure, and its structural formula is:
X is H or CH in the formula
3, B is the part of unsaturated vinyl monomer remainder.
Among the present invention related material be by hydrolyzable discharge silicone oil acrylic resin, contain the antifouling activity functional group modified silicone resin with make after methyl silicon resin mixes by a certain percentage, this material is after adding the triethylene tetramine solidifying agent, film and to form surface with regular concave-convex micro-structure, the diatom larva of filming in the laboratory that forms adheres to experiment and real extra large link plate biological attachment experiment shows, have and prevent that preferably marine life from adhering to and stained effect, and the non-environmental-pollution problem.
