Description
Technical field
The invention belongs to Environmental Protective Water-paint technical fields, and in particular to one kind can be used for that marine ship is antifouling and ocean work
The aqueous non-toxic fluorine silicon antifouling paint of journey.
Background technique
Contain various metals salt in seawater, there is corrosivity to ocean engineering such as deep sea fishing ground steel frame construction coating, pass through
The seawater of a period of time impregnates, and coating can generate mostly to fall off and crack, and exposes the steel frame construction of bottom, seawater and steel frame construction
Primary battery layer is formed, the corrosion in surface layer steel face is accelerated, if things go on like this, the safety of the ocean engineerings such as deep sea fishing ground can be caused very big
Threat.
In addition, the pollution that marine organisms attachment generates is that a very headache is asked for ship and ocean engineering building
Topic, the biological pollution that can cause large area biological attachment are usually because of macros such as barnacle, diatom, mussel and primary
Animal individual is attached to marine surface, it is difficult to such large area ocean attachment is washed out with ship's speed promotion, marine organisms attachment increases
The weight of ship and deep sea fishing ground is added, so that marine fuel oil be caused to expend increase, a large amount of manpower of deep sea fishing ground needs and object
Power carries out decontamination work.
The superpower wear-resistant paint that deep sea fishing ground uses during construction at present, main purpose are to improve it in the seawater
Corrosion resistance and crocking resistance, and do not have anti-pollution, it needs to configure corresponding cleaning equipment and personnel carries out self
Cleaning, wastes a large amount of manpower and material resources.Commercially available anti-fouling ship paint is all based on oiliness, and effect preferably has Aksu promise
Intelsleek1100SR, the high-end antifouling paint of marine rainbow old man Hempaguard and the Atlantic+ middle-end antifouling paint of Bell,
The principle that wherein 1100SR and Atlantic+ is all made of low-surface-energy carries out antifouling, i.e. attachment of the reduction protein on coating
Power, antifouling to achieve the effect that, Hempaguard melts using by silicone hydrogels and controllable biocide release tech
Together in surface energy in a kind of coating, had both been reduced, the biology that adherency is killed further through insecticide is antifouling to achieve the purpose that,
And insecticide can damage marine ecology.
The above valuable product, average price are well beyond much engaged in ocean Construction Company in 800 yuan/kilogram or more
Expection, increase construction cost, and these three products are oil products, are sprayed using toluene as diluent, greatly
The organic matter volatilization of amount causes health threat to constructor and brings a large amount of environmental pollution.Three kinds of coating are made with low-surface-energy
Anti-pollution relies primarily on, however while improving surface depolluting properties, the adhesive force of antifouling paint is also reduced, is needed
The good epoxy bottom of adsorption capacity is sprayed, the cost of entire hull is substantially increased.In addition, three kinds of antifouling paints are contained with fluorine-containing
Silene hydrocarbon causes free radical polymerization as main crosslinking component, using peroxide, and obtained coating has certain brittleness,
Edge location, which is prone to wear, during practical sea-freight falls off.
