Abstract
The antifouling coating with low surface energy for marine mesh cage cover is used forsolving the problem of damaging life attachment. The antifouling coating with low surface energy is compounded with polyurethane, curing agent, ethyl acetate, zinc oxide, magnesium oxide, PTFE and chloropafaffin in certain weight proportion and through grinding and mixing. The antifouling coating with low surface energy is used in coating marine mesh cage cover.
Description
Technical field
The present invention relates to prevent the antifouling paint of the stained Coating for marine nesh cage cover of marine sessile organism.
Background technology
Marine mesh cage is cultured and is kept the unimpeded primary condition that is assurance cultured fishes health, grows fast of water body current.And nearly thousand kinds of fouling organisms very easily adhere on the net cage dictyosome and growth fast in the ocean, hinder the exchange of net cage water body, cause the aquaculture water anoxic, and fish disease takes place frequently, and directly jeopardizes the growth of fish.
At present, a kind of cage netting anti-fouling method is to adopt antifouling paint to stop marine organisms that the marine mesh cage dictyosome is adhered to comparatively effectively anti-fouling method.
But marine antifouling coating utilizes toxic agent contained in the coating to ooze out with certain speed, and forming around material has the concentration of poisons layer of toxic action to marine plant spore and marine animal larva, thereby reaches anti-fouling effect.These play the toxic agent of antifouling effect such as red precipitate, organotin, organic lead can cause the seawater water pollution, cause biomutation, and pollution of ecological environment has potential harm to marine ecology balance and human health.And traditional toxicity antifouling paint is general only some biology is had restraining effect, and along with the continuous release of toxicant, its anti-fouling effect also descends gradually.
Low surface energy anti-fouling paint is a surface physics principle of utilizing material, makes the larva of fouling organism and spore be difficult for adhering to or reduces its adhere firmly, thereby prevent adhering to of various marine lifes.There is not the release loss problem of toxicant in the effect of low surface energy anti-fouling paint coating based surface physics, can play long-term antifouling effect.
A kind of low surface energy anti-fouling paint by 50% Polyurethane, 7.0% solidifying agent, 40.0% vinyl acetic monomer, 1.0% zinc oxide, the preparation of 2.0% magnesium oxide is painted on the etting material after the shallow sea linked network is tested 3 months, the biological attachment area is more than 30%, the artifact bond area was more than 60% in 6 months, the artifact bond area reached 100% in 12 months, did not reach required antifouling requirement.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of nylon etting material surface that is suitable for being coated on, and prevent the low surface energy anti-fouling paint that marine sessile organism is stained.
Technical scheme of the present invention adopts Polyurethane, solidifying agent DN-EB, vinyl acetic monomer, zinc oxide, magnesium oxide, it is characterized in that adding in the coating composition tetrafluoroethylene, clorafin; Each composition weight percentage composition of coating is: urethane 30-35%, solidifying agent DN-EB 5-10%, vinyl acetic monomer 30-40%, tetrafluoroethylene 20-30%, clorafin 2-10%, zinc oxide 0.5-2%, magnesium oxide 0.2-2%; During modulation earlier with clorafin and color filler zinc oxide, magnesium oxide ground and mixed; Adding the vinyl acetic monomer organic solvent in Polyurethane stirs, after can not see solid mass in the solution to be mixed, in 90 minutes, divide and progressively add tetrafluoroethylene 8 times and ground mixed fillers fully stirs, add solidifying agent DN-EB in proportion, stirring promptly to become is suitable for the antifouling coating with low surface energy for marine mesh cage cover that cage netting uses.
Coating by coating composition preparation of the present invention, being painted on the try net sheet hangs to produce between the net cage in the test sea area and tests, test duration 12 months, biological attachment area 30～40%, show that the antifouling paint for preparing by the present invention can play the antifouling effect to cage netting, has solved low surface energy anti-fouling paint and use a difficult problem that does not reach required antifouling requirement on cage netting.
Embodiment
