Abstract
The present invention relates to ship paint with the resistance of marine organism adhesion. The paint comprises (A) silicon dioxide, alumina super fine powder or the mixture of the silicon dioxide and the alumina super fine powder and (B) polyethylene or elastic polyurea, wherein the proportion of (A) and (B) is from 1:20 to 1:10. The ship paint with the resistance of marine organism adhesion of the present invention can be used for effectively inhibiting marine organisms, such as oyster shells, algae, etc. from growing and being attached to the surface of a ship shell. In addition, the corrosion resistance of the ship shell and a pipeline is strong, and no nuisance exists.
Description
Technical field
The present invention relates to be used for the hull of ships and the coating of hull tubing, relate more specifically to ship coating and using method that a kind of anti-marine organisms adhere to.
Background technology
In shipbuilding body material, in order to suppress the apposition growth of marine organisms such as oyster and so on, people alow with the deleterious paint of drain water piping brushing, or strike off with mechanical means is rigid.First method pollutes to seawater, and second method causes damage to hull.At present, the non-harmful ship coating that does not also have a kind of effective inhibition marine organisms to adhere in the world.For this reason, the objective of the invention is to adhere to existing shortcoming anti-marine organisms, propose a kind of new coating at the hull and the used pipeline of traditional ships.
Summary of the invention
The ship coating that anti-marine organisms of the present invention adhere to can suppress the apposition growth on the ship hull surface such as marine organisms such as oyster, algae etc. effectively, thereby solved the unsolved problem of prior art, thereby provide economical and technical benefit for ships manufacturers.
Therefore, first purpose of the present invention provides the ship coating that anti-marine organisms adhere to, and comprising: (A) silicon-dioxide, ultra-fine alumina powder material, or the mixture of the two; (B) polyethylene or resilient polyurea; Wherein (A) and part by weight (B) are 1: 20 to 1: 10.
Superfine powder of the present invention is meant granularity greater than 1000 orders, 1000-4000 order especially, and 1000-2000 order more generally, the upper limit of granularity is not special restriction.
Poly molecular-weight average is preferably 5000-100000, more preferably 10000-80000.The molecular-weight average of polyureas is preferably 1000-80000, more preferably 5000-50000.
Also optional component (C) linking agent that comprises of ship coating of the present invention, linking agent is known in the art, it for example is multifunctional acrylic compounds, as Hydroxyethyl acrylate, Propylene glycol monoacrylate etc., its consumption is a conventional amount used, for example is the 0.1-0.5wt% based on polyethylene or resilient polyurea.
Second purpose of the present invention provides the production method of the ship coating that anti-marine organisms adhere to, comprise (A) silicon-dioxide, ultra-fine alumina powder material, or the mixture of the two and (B) polyethylene or resilient polyurea uniform mixing; Wherein (A) and part by weight (B) are 1: 20 to 1: 10.
Mixing can be carried out at normal temperatures, also can be higher than the temperature of normal temperature, for example carries out under 30-120 ℃.
The 3rd purpose of the present invention provides the preparation method of the coating peculiar to vessel that anti-marine organisms adhere to, and this method may further comprise the steps:
(1) with (A) silicon-dioxide, ultra-fine alumina powder material, or the mixture of the two and (B) polyethylene or resilient polyurea uniform mixing, wherein (A) is 1: 20 to 1: 10 with (B) part by weight;
(2) will mix all-in-one-piece coating is applied on hull surface and/or the pipeline peculiar to vessel; With
(3) dry solidification.
Wherein the granularity of superfine powder is greater than 1000 orders, especially 1000-4000 order, more generally 1000-2000 order, wherein poly molecular-weight average is preferably 5000-100000,10000-80000 more preferably, the molecular-weight average of polyureas is preferably 1000-80000, more preferably 5000-50000.
Method of application can be a spraying method, spread coating, sputtering method etc.The preferred spraying method that uses more preferably adopts centrifugal vacuum spraying equipment to spray, and also can use other spraying equipment.The thickness of applying coating for example can be 10 microns to 5 millimeters, preferred 100 microns to 4 millimeters, and more preferably 1-3 millimeter.
Dry solidification can adopt the seasoning mode, or adopts heating, radiation or forced air drying mode to finish.
Centrifugal vacuum spraying equipment can be buied from the market, and its temperature, pressure all can be regulated.Before hull and pipeline peculiar to vessel are sprayed, generally eliminate rust earlier, cleaning, drying treatment.
The ship coating that anti-marine organisms of the present invention adhere to not only makes hull and pipeline be difficult for adhering to marine organisms, and makes the erosion resistance of hull and pipeline stronger, and nuisanceless.Through probationary certificate, with the hull of paint spay-coating of the present invention, travelling in the ocean did not have marine organisms in 1 year and adheres to, and hull surface is smooth, and the coating adhere firmly, do not have come off, the scaling phenomenon, shown that coating of the present invention has good effect.
Though the boats and ships that coating of the present invention is particularly useful for travelling in the ocean also can be used for the boats and ships that travel at fresh water such as rivers and lakes, have the effectiveness that anti-limnobios adheres to equally.
