Abstract
The present invention relates to a preparation method for an amide derivative copolymer, which is characterized in that under the action of a free radical initiating agent, an acrylamide derivative and a vinyl unsaturated monomer are copolymerized. The prepared amide derivative copolymer can be used for preparing antifouling paint. The antifouling paint is composed of the components of the following proportion by weight: 150 to 250% of copolymer, 5 to 20% of plasticizing agent, 1 to 35% of filling agent and 5 to 60% of antifouling agent. The antifouling paint can prevent marine organisms from attaching on the surfaces of nets, vessels, coastal facilities, etc., the antifouling paint has the advantage of good antifouling performance, and the problems of cracking, peeling, etc. can not occur.
Description
Technical field
The present invention relates to a kind of preparation method of amide derivatives multipolymer and the application in antifouling paint thereof.
Technical background
When fishing net, hull bottom, underwater facility etc. are exposed in the seawater for a long time, its outward appearance and function very easily stick to surface growth because of various marine fouling organisms and breeding suffers damage, and these marine fouling organisms comprise algae and mushrooms such as bacterium, fungi such as animals such as barnacle, hydra, Ascidian, diatom, green alga.When marine fouling organism sticks on the fishing net surface growth and breeding, stop up mesh, make the resistance of Fixed nets device increase, catch descends; And the inside and outside water body exchange of aquaculture net cage minimizing, the dissolved oxygen content in the case reduces, and the speed of growth of culturing sea-food descends even death; Make the weight of fishing net and the resistance of current increase, shorten the work-ing life of netting gear.At present, the people is arranged the multipolymer of methacrylic acid tributyl tin ester and methyl methacrylate and Red copper oxide (Cu
2O) composition is coated on surfaces such as hull bottom as a kind of antifouling paint, can prevent the harm of marine fouling organism effectively.Multipolymer in this antifouling paint is the meeting hydrolysis in seawater, discharges tributyl tin (TBT), brings into play antifouling effect.But the TBT harm marine eco-environment and sea farming industry cause gender variation and the housing distortion of oyster, blood clam and mussel as TBT.For example, the silyl ester class antifouling paint of describing in, flat 4 (1992)-264169 peace 4 (1992)-264168 flat 4 (1992)-264170 in Japanese publication can be used as not stanniferous antifouling paint, yet as what in flat 6 (1994)-157941 peace 6 (1994)-157940 of Japanese publication, point out, not only antifouling property is poor for this class antifouling paint, and be full of cracks very easily takes place and problem such as peel off.
Summary of the invention
The purpose of this invention is to provide a kind of preparation method and application of amide derivatives multipolymer, it can remedy the above-mentioned deficiency of prior art.
A kind of preparation method of amide derivatives multipolymer is characterized in that under action of free radical initiator, makes acrylamide derivative and unsaturated vinyl monomer copolymerization.
A kind of amide derivatives multipolymer is characterized in that preparing antifouling paint with it.
Multipolymer of the present invention can be used for preparing antifouling paint, and this coating can prevent that marine organisms from adhering on surfaces such as netting gear, naval vessel and coastal facility, and antifouling property is good, be full of cracks can not take place and problem such as peel off.
